)

ZAP CLOB method names. These are FROZEN and MUST stay byte-identical with the d-chain gateway (github.com/luxfi/dex/pkg/api/zap_server.go) and the EVM precompile (github.com/luxfi/precompile/dex/engine_zap.go). The proxy never interprets order semantics — it forwards these frames verbatim to the single source-of-truth matcher.

	// DepositReqSize / WithdrawReqSize: user[16] + asset[8] + amount[8].

	WithdrawReqSize = 16 + 8 + 8 // 32
	// BalanceRespSize: status[1] + realizedAmount[8].
	BalanceRespSize = 1 + 8
)

Custody wire sizes (FROZEN, == github.com/luxfi/dex/pkg/zapwire). The proxy re-defines them since it cannot import the cgo-tagged d-chain package; a parity test pins byte-equality.

View Source 
const FillWireSize = 17

FillWireSize is one fill in a clob_submit response: price[8]+size[8]+side[1]. FROZEN — must equal dex/pkg/api.FillWireSize and the precompile's fillWireSize.

Variables

View Source 
var ErrRelayNotConfigured = errors.New("dexvm: d-chain ZAP endpoint not configured")

ErrRelayNotConfigured is returned when an order relay is attempted but no d-chain ZAP endpoint is configured. The proxy is inert on the relay leg until the venue operator points dex-zap-endpoint at a d-chain gateway.

Types

type Block 

type Block struct {
	// contains filtered or unexported fields
}

Block represents a DEX VM block that wraps the functional ProcessBlock results. It implements the chain.Block interface required for the ChainVM.

func (*Block) Accept 

func (b *Block) Accept(ctx context.Context) error

Accept marks the block as accepted and commits the proxy's state batch ATOMICALLY with the cross-chain shared-memory operations accumulated during Verify (the settlement leg) — the single commit point.

func (*Block) Bytes 

func (b *Block) Bytes() []byte

Bytes returns the serialized block.

WIRE FORMAT (NETWORK-UPGRADE-GATED, LOCKSTEP — RED finding #9). The block now carries the proposer's confirmed d-chain fills so every validator settles from bytes instead of relaying per-validator. The layout is: 

height[8] | timestamp[8] | parentID[32] |
txCount[4] | txCount × ( txLen[4] | txBytes ) |
carried-fills section (carried_fills.go encodeCarriedFills):
  entryCount[4] | entryCount × ( txIndex[4] | fillCount[4] | fillCount×17 ) |
  sigLen[4] | sig[sigLen]   // reserved fill-attestation, empty today

The txCount prefix (NEW) makes the txs self-delimiting so the carried-fills section can follow unambiguously; the prior format ran txs to end-of-buffer. This is a consensus-breaking change activated in lockstep across the validator set behind a network upgrade.

func (*Block) Height 

func (b *Block) Height() uint64

Height returns the block height

func (*Block) ID 

func (b *Block) ID() ids.ID

ID returns the unique identifier for this block

func (*Block) Parent 

func (b *Block) Parent() ids.ID

Parent returns the parent block's ID (alias for ParentID)

func (*Block) ParentID 

func (b *Block) ParentID() ids.ID

ParentID returns the parent block's ID

func (*Block) Reject 

func (b *Block) Reject(ctx context.Context) error

Reject marks the block as rejected

func (*Block) Status 

func (b *Block) Status() uint8

Status returns the block's status as uint8

func (*Block) Timestamp 

func (b *Block) Timestamp() time.Time

Timestamp returns the block timestamp

func (*Block) Verify 

func (b *Block) Verify(ctx context.Context) error

Verify verifies the block is valid by processing it deterministically, then attaches the block-CARRIED fills (RED #9) so accept settles from bytes rather than relaying. Verify performs NO d-chain I/O on any node — the proposer already relayed once at build (BuildBlockResult) and the fills travel in the block bytes.

type BlockResult 

type BlockResult struct {
	// BlockHeight is the height of the processed block.
	BlockHeight uint64

	// Timestamp is when this block was processed.
	Timestamp time.Time

	// StateRoot is the merkle root of the proxy's state after this block.
	StateRoot ids.ID
	// contains filtered or unexported fields
}

BlockResult is the deterministic result of processing a block on the proxy. A STATELESS ATOMIC ZAP PROXY produces NO MatchedTrades / FundingPayments / Liquidations — matching lives ONLY on the d-chain. The proxy's per-block output is the cross-chain atomic operations it accumulated (committed at accept) and the state root over its (tiny) replay/consumption state.

type ChainVM 

type ChainVM struct {
	// contains filtered or unexported fields
}

ChainVM wraps the functional DEX VM to implement the chain.ChainVM interface required for running as an L2 chain plugin.

func NewChainVM 

func NewChainVM(logger log.Logger) *ChainVM

NewChainVM creates a new ChainVM that wraps a functional DEX VM

func (*ChainVM) BuildBlock 

func (cvm *ChainVM) BuildBlock(ctx context.Context) (chain.Block, error)

BuildBlock implements the chain.ChainVM interface. It builds a new block from pending transactions AND, as the block PROPOSER, performs the network-wide-ONCE d-chain relay (VM.BuildBlockResult -> obtainFills), carrying the confirmed fills in the block bytes so every validator settles from them without relaying (RED finding #9). This is the ONLY chain entry point that triggers a d-chain relay; Verify and Accept never do.

The proposer chooses the block time here (wall clock, clamped non-decreasing) and carries it in the bytes — the consensus-agreement point. The block id is the hash of the serialized bytes (header + txs + carried fills), so the id commits to the carried fills (a peer cannot swap fills while keeping the same id).

func (*ChainVM) BuildVertex 

func (cvm *ChainVM) BuildVertex(ctx context.Context) (vertex.Vertex, error)

BuildVertex drains pending txs and batches non-conflicting ones.

func (*ChainVM) Connected 

func (cvm *ChainVM) Connected(ctx context.Context, nodeID ids.NodeID, v *chain.VersionInfo) error

Connected implements the chain.ChainVM interface

func (*ChainVM) CreateHandlers 

func (cvm *ChainVM) CreateHandlers(ctx context.Context) (map[string]http.Handler, error)

CreateHandlers implements the interface expected by chain manager for HTTP registration

func (*ChainVM) Disconnected 

func (cvm *ChainVM) Disconnected(ctx context.Context, nodeID ids.NodeID) error

Disconnected implements the VM interface

func (*ChainVM) FeePolicy added in v1.2.6 

func (cvm *ChainVM) FeePolicy() fee.Policy

FeePolicy exposes the chain's declared fee policy for diagnostics and the boot-time Validate gate.

func (*ChainVM) GetBlock 

func (cvm *ChainVM) GetBlock(ctx context.Context, blkID ids.ID) (chain.Block, error)

GetBlock implements the chain.ChainVM interface. It returns a block by its ID.

func (*ChainVM) GetBlockIDAtHeight 

func (cvm *ChainVM) GetBlockIDAtHeight(ctx context.Context, height uint64) (ids.ID, error)

GetBlockIDAtHeight returns the block ID at the given height

func (*ChainVM) GetInnerVM 

func (cvm *ChainVM) GetInnerVM() *VM

GetInnerVM returns the inner proxy VM for direct access.

func (*ChainVM) Gossip 

func (cvm *ChainVM) Gossip(ctx context.Context, nodeID ids.NodeID, msg []byte) error

Gossip implements the VM interface

func (*ChainVM) HealthCheck 

func (cvm *ChainVM) HealthCheck(ctx context.Context) (chain.HealthResult, error)

HealthCheck implements the VM interface

func (*ChainVM) Initialize 

func (cvm *ChainVM) Initialize(
	ctx context.Context,
	vmInit vm.Init,
) error

Initialize implements the VM interface

func (*ChainVM) LastAccepted 

func (cvm *ChainVM) LastAccepted(ctx context.Context) (ids.ID, error)

LastAccepted implements the chain.ChainVM interface. It returns the ID of the last accepted chain.

func (*ChainVM) NewHTTPHandler 

func (cvm *ChainVM) NewHTTPHandler(ctx context.Context) (http.Handler, error)

NewHTTPHandler implements the chain.ChainVM interface

func (*ChainVM) ParseBlock 

func (cvm *ChainVM) ParseBlock(ctx context.Context, data []byte) (chain.Block, error)

ParseBlock implements the chain.ChainVM interface. It parses a block from bytes.

func (*ChainVM) ParseVertex 

func (cvm *ChainVM) ParseVertex(ctx context.Context, b []byte) (vertex.Vertex, error)

ParseVertex deserializes a vertex from bytes.

func (*ChainVM) Request 

func (cvm *ChainVM) Request(ctx context.Context, nodeID ids.NodeID, requestID uint32, deadline time.Time, request []byte) error

Request implements the VM interface

func (*ChainVM) Response 

func (cvm *ChainVM) Response(ctx context.Context, nodeID ids.NodeID, requestID uint32, response []byte) error

Response implements the VM interface

func (*ChainVM) SetPreference 

func (cvm *ChainVM) SetPreference(ctx context.Context, blkID ids.ID) error

SetPreference implements the chain.ChainVM interface. It sets the preferred block for building new blocks.

func (*ChainVM) SetState 

func (cvm *ChainVM) SetState(ctx context.Context, state uint32) error

SetState implements the VM interface

func (*ChainVM) Shutdown 

func (cvm *ChainVM) Shutdown(ctx context.Context) error

Shutdown implements the VM interface

func (*ChainVM) SubmitTx 

func (cvm *ChainVM) SubmitTx(tx []byte) error

SubmitTx adds a transaction to the pending pool. This is the canonical user-mempool entry on D-Chain — every public submission funnels through here. The FeePolicy gate refuses zero-fee tx before the bytes touch pendingTxs.

Internal callers (consensus engine -> VM, replay) feed pendingTxs directly via BuildBlock; they do NOT route through SubmitTx, so the fee gate stays out of the consensus-internal path.

func (*ChainVM) Version 

func (cvm *ChainVM) Version(ctx context.Context) (string, error)

Version implements the VM interface

func (*ChainVM) WaitForEvent 

func (cvm *ChainVM) WaitForEvent(ctx context.Context) (vm.Message, error)

WaitForEvent implements the chain.ChainVM interface. It blocks until an event occurs that should trigger block building.

type DexVertex 

type DexVertex struct {
	// contains filtered or unexported fields
}

DexVertex represents a DAG vertex in the DEX proxy chain.

func (*DexVertex) Accept 

func (v *DexVertex) Accept(ctx context.Context) error

func (*DexVertex) Bytes 

func (v *DexVertex) Bytes() []byte

func (*DexVertex) Conflicts 

func (v *DexVertex) Conflicts(other *DexVertex) bool

Conflicts returns true if this vertex and other share any (symbol, side, orderID) tuple.

func (*DexVertex) ConflictsVertex 

func (v *DexVertex) ConflictsVertex(other vertex.Vertex) bool

ConflictsVertex performs the same check against the vertex.Vertex interface.

func (*DexVertex) Epoch 

func (v *DexVertex) Epoch() uint32

func (*DexVertex) Height 

func (v *DexVertex) Height() uint64

func (*DexVertex) ID 

func (v *DexVertex) ID() ids.ID

func (*DexVertex) Parents 

func (v *DexVertex) Parents() []ids.ID

func (*DexVertex) Reject 

func (v *DexVertex) Reject(ctx context.Context) error

func (*DexVertex) Status 

func (v *DexVertex) Status() choices.Status

func (*DexVertex) Timestamp added in v1.3.8 

func (v *DexVertex) Timestamp() time.Time

func (*DexVertex) Txs 

func (v *DexVertex) Txs() []ids.ID

func (*DexVertex) Verify 

func (v *DexVertex) Verify(ctx context.Context) error

type Factory 

type Factory struct {
	config.Config
}

Factory creates new DEX VM instances.

func (*Factory) New 

func (f *Factory) New(logger log.Logger) (interface{}, error)

New implements vms.Factory interface. It creates a new DEX ChainVM instance with the factory's configuration. The ChainVM wrapper implements block.ChainVM for integration with the chains manager. Allocates a per-VM GPU session at PriorityHigh because the DEX hot path is latency-critical (1ms block times).

type Fill added in v1.3.8 

type Fill struct {
	Price float64
	Size  float64
	Side  uint8
}

Fill is one execution returned by the d-chain matcher: price + size + the taker side this submit took with. The proxy derives the settlement delta ONLY from these server-returned fills — never from a client-supplied amount.

func DecodeFills added in v1.3.8 

func DecodeFills(data []byte) ([]Fill, error)

DecodeFills parses a clob_submit response: count[4] then count×(price[8] + size[8] + side[1]). Every field is range-checked so a backend that lies (or a MITM on the socket) cannot inject a structurally invalid fill into settlement: price/size must be finite and strictly positive, and side MUST be a valid CLOB side (0=BUY, 1=SELL). A side byte outside {0,1} is malformed wire exactly like a NaN price — rejecting it here keeps a Fill value always well-formed, so no downstream consumer ever sees an impossible side. (Cross-fill side CONSISTENCY — "a single submit takes exactly one side" — is a settlement-policy invariant enforced in settleFromFills, not a per-fill wire property; the two checks own different invariants and do not overlap.)

type Genesis 

type Genesis struct {
	// DexZapEndpoint optionally overrides the d-chain ZAP gateway address.
	DexZapEndpoint string `json:"dexZapEndpoint,omitempty"`
	// TrustedChains are chain IDs trusted for the Warp attestation channel.
	TrustedChains []string `json:"trustedChains,omitempty"`
}

Genesis is the proxy's genesis configuration: trusted chains for the attestation channel and the d-chain ZAP endpoint. There are NO trading pairs / pools / perp markets — the proxy seeds no DEX state.

type OrderKey 

type OrderKey struct {
	// Market is the 32-byte poolId (hex) for order relays, or "utxo" for the
	// atomic-import double-spend key.
	Market  string
	Side    uint8
	OrderID ids.ID
}

OrderKey is the conflict key for the proxy: (poolId, side, orderID) for relay envelopes, or the consumed source-UTXO id for imports. Two vertices conflict iff their OrderKey sets intersect — relays/cancels touching the same resting order, or imports claiming the same exported UTXO. The proxy does NOT match, so this is a transport-level conflict key, not a matching one.

type RelayClient added in v1.3.8 

type RelayClient struct {
	// contains filtered or unexported fields
}

RelayClient forwards byte-identical clob_* frames to the d-chain's ZAP gateway. It is PURE TRANSPORT to the single source-of-truth matcher: it holds NO order/pool/book state, performs NO matching, and never mints. This is the ORDER RELAY leg (NOT atomic, NOT consensus) of the two-primitive proxy; value settlement is the separate atomic SharedMemory import/export leg (atomic.go).

func NewRelayClient added in v1.3.8 

func NewRelayClient(addr string, timeout time.Duration) *RelayClient

NewRelayClient creates a relay targeting the d-chain ZAP endpoint (e.g. "127.0.0.1:9100"). An empty addr yields a relay that returns ErrRelayNotConfigured on every call — the inert relay leg.

func (*RelayClient) Close added in v1.3.8 

func (r *RelayClient) Close() error

Close closes the cached connection, if any.

func (*RelayClient) Configured added in v1.3.8 

func (r *RelayClient) Configured() bool

Configured reports whether a d-chain endpoint is set.

func (*RelayClient) Relay added in v1.3.8 

func (r *RelayClient) Relay(ctx context.Context, method string, payload []byte) ([]byte, error)

Relay forwards an opaque clob_* frame to the d-chain and returns the raw response bytes verbatim. The proxy does not interpret the payload beyond routing it to the configured matcher.

type Status 

type Status uint8

Status represents block status 

const (
	StatusUnknown Status = iota
	StatusProcessing
	StatusAccepted
	StatusRejected
)

type VM 

type VM struct {
	config.Config
	// contains filtered or unexported fields
}

VM implements the DEX proxy Virtual Machine: a STATELESS ATOMIC ZAP PROXY on the Lux consensus network. It holds ZERO canonical DEX state. It does exactly two orthogonal things, each its own primitive (do NOT conflate them):

  1. ORDER RELAY (proxy -> d-chain): forwards byte-identical clob_* frames over ZAP (RelayClient) to the single source-of-truth matcher. NOT atomic, NOT consensus — pure transport.

  2. VALUE SETTLEMENT (C-Chain <-> proxy, atomic): moves value in/out via atomic.SharedMemory import/export (atomic.go), exactly as X/P-chains do. The ONLY primitive in the proxy that moves value across chains.

Warp is retained ONLY as the optional fill-attestation channel (off the hot path) — it is NOT the settlement primitive.

DESIGN: No background goroutines. All operations are block-driven and deterministic, so every node produces identical state from identical inputs.

func NewVMForTest 

func NewVMForTest(cfg config.Config, logger log.Logger) *VM

NewVMForTest creates a new VM instance for testing purposes.

func (*VM) BuildBlockResult added in v1.3.8 

func (vm *VM) BuildBlockResult(ctx context.Context, blockHeight uint64, blockTime time.Time, blockTxs [][]byte) (*BlockResult, error)

BuildBlockResult is the PROPOSER's full build of a block: it plans the block (the deterministic ProcessBlock pass) and then performs the network-wide-ONCE d-chain relay (obtainFills), attaching the confirmed fills to the result. The caller (BuildBlock / BuildVertex) serializes result.carriedFills + result.fillSig into the block/vertex bytes so every validator settles from them — the matcher is hit exactly once for the whole network (RED finding #9).

This is the ONLY method that triggers a d-chain relay. Verify (ProcessBlock) and Accept (acceptBlock) never relay. A non-proposer obtains the same fills by parsing the block bytes, not by calling this.

The relay is best-effort per order: obtainFills carries a zero-fill entry for any order whose relay failed, so the build always yields a valid block (the escrow is refunded at settle). It returns an error only on a fault that should abort the proposal entirely (e.g. the planning pass failed).

func (*VM) Connected 

func (vm *VM) Connected(ctx context.Context, nodeID ids.NodeID, v *version.Application) error

Connected implements consensuscore.VM.

func (*VM) CreateHandlers 

func (vm *VM) CreateHandlers(ctx context.Context) (map[string]http.Handler, error)

CreateHandlers implements consensuscore.VM. The proxy's API is a thin pass-through to the relay client (no local book to query).

func (*VM) CrossChainRequest 

func (vm *VM) CrossChainRequest(ctx context.Context, sourceChainID ids.ID, requestID uint32, deadline time.Time, request []byte) error

CrossChainRequest implements consensuscore.VM. The proxy retains ONLY the Warp attestation-ingress dispatch — it does NOT move value over Warp (the atomic SharedMemory import/export leg does that). Cross-chain swap/transfer value handlers were removed; an incoming Warp message is a fill attestation receipt, off the settlement hot path.

func (*VM) CrossChainRequestFailed 

func (vm *VM) CrossChainRequestFailed(ctx context.Context, chainID ids.ID, requestID uint32, appErr *consensuscore.AppError) error

CrossChainRequestFailed implements consensuscore.VM.

func (*VM) CrossChainResponse 

func (vm *VM) CrossChainResponse(ctx context.Context, chainID ids.ID, requestID uint32, response []byte) error

CrossChainResponse implements consensuscore.VM.

func (*VM) Disconnected 

func (vm *VM) Disconnected(ctx context.Context, nodeID ids.NodeID) error

Disconnected implements consensuscore.VM.

func (*VM) GetBlockHeight 

func (vm *VM) GetBlockHeight() uint64

GetBlockHeight returns the current block height.

func (*VM) GetLastBlockTime 

func (vm *VM) GetLastBlockTime() time.Time

GetLastBlockTime returns the timestamp of the last processed block.

func (*VM) Gossip 

func (vm *VM) Gossip(ctx context.Context, nodeID ids.NodeID, msg []byte) error

Gossip implements consensuscore.VM. The proxy gossips nothing matcher-related (it has no book); it only acknowledges peer messages.

func (*VM) HealthCheck 

func (vm *VM) HealthCheck(ctx context.Context) (chain.HealthResult, error)

HealthCheck implements consensuscore.VM.

func (*VM) Initialize 

func (vm *VM) Initialize(ctx context.Context, vmInit vmcore.Init) error

Initialize implements consensuscore.VM. It sets up the proxy with the provided context, database, and genesis/config data.

func (*VM) IsBootstrapped 

func (vm *VM) IsBootstrapped() bool

IsBootstrapped reports whether the proxy is fully bootstrapped.

func (*VM) ProcessBlock 

func (vm *VM) ProcessBlock(ctx context.Context, blockHeight uint64, blockTime time.Time, blockTxs [][]byte) (*BlockResult, error)

ProcessBlock is the proxy's PURE DETERMINISTIC VERIFY: it validates the block's transactions and builds a plan, performing ZERO d-chain I/O. Concretely it applies the atomic IMPORT legs (consuming UTXOs into the versiondb in-memory layer, accumulating RemoveRequests) and the EXPORT legs, and it records every order RELAY as a plannedRelay. Matching is NEVER done here — it lives only on the d-chain.

Why no relay here (RED finding #9): a Verified block is later decided Accept OR Reject, and Reject must undo everything Verify did with a plain db.Abort(). But more fundamentally, Verify runs on EVERY validator: a clob_submit issued here would be relayed per-validator against a MOVING d-chain book, so each validator would observe independently-timed fills => divergent settlement => divergent StateRoot => the network forks. The relay is therefore performed exactly ONCE, by the block PROPOSER at build (VM.obtainFills), and the confirmed fills are CARRIED in the block bytes; every validator settles purely from those carried fills (settleCarried at accept). Block output is thus a pure function of (height, carried time, tx bytes, carried fills).

CONSERVATION ORDERING within a block: each tx is processed in order, and an import always precedes the relay/export that depends on its locked value. The plan preserves that order (settleCarried settles in capture order at accept).

func (*VM) Relay added in v1.3.8 

func (vm *VM) Relay() api.Relayer

Relay exposes the relay client to the API pass-through layer as the neutral api.Relayer surface (the proxy's only DEX capability is transport).

func (*VM) Request 

func (vm *VM) Request(ctx context.Context, nodeID ids.NodeID, requestID uint32, deadline time.Time, request []byte) error

Request implements consensuscore.VM. The proxy serves no orderbook/pool sync (it holds no such state); unknown requests are ignored.

func (*VM) RequestFailed 

func (vm *VM) RequestFailed(ctx context.Context, nodeID ids.NodeID, requestID uint32, appErr *consensuscore.AppError) error

RequestFailed implements consensuscore.VM.

func (*VM) Response 

func (vm *VM) Response(ctx context.Context, nodeID ids.NodeID, requestID uint32, response []byte) error

Response implements consensuscore.VM.

func (*VM) SetState 

func (vm *VM) SetState(ctx context.Context, stateNum uint32) error

SetState implements consensuscore.VM. NOTE: No background goroutines.

func (*VM) Shutdown 

func (vm *VM) Shutdown(ctx context.Context) error

Shutdown implements consensuscore.VM.

func (*VM) Version 

func (vm *VM) Version(ctx context.Context) (string, error)

Version implements consensuscore.VM.
