Functions

func AddCustomRPC added in v0.5.0 

func AddCustomRPC(cfg *config.Config, chainID int, chainName, endpoint string, readOnly bool) error

AddCustomRPC adds a single custom RPC endpoint for a chain to the eRPC ConfigMap. Uses the "custom-" prefix to distinguish from ChainList-sourced upstreams. When readOnly is true, eth_sendRawTransaction and eth_sendTransaction are blocked.

func AddPublicRPCs added in v0.5.0 

func AddPublicRPCs(cfg *config.Config, chainID int, chainName string, endpoints []RPCEndpoint, readOnly bool) error

AddPublicRPCs adds ChainList RPCs for a chain to the eRPC ConfigMap. When readOnly is true, eth_sendRawTransaction and eth_sendTransaction are blocked.

func CheckNetworkDiskSpace added in v0.10.0 

func CheckNetworkDiskSpace(u *ui.UI, dataDir, network, mode, executionClient string, scope ArchiveScope) error

CheckNetworkDiskSpace warns when the data directory has less free disk than the install is expected to need. The default answer is to continue: in non-interactive contexts (no TTY, JSON mode) the prompt auto-accepts so scripted installs don't deadlock. The user only blocks the install by explicitly declining at an interactive prompt.

func DefaultChainListFetcher added in v0.5.0 

func DefaultChainListFetcher() ([]byte, error)

DefaultChainListFetcher fetches from the real ChainList API.

func Delete 

func Delete(cfg *config.Config, u *ui.UI, deploymentIdentifier string) error

Delete removes the network deployment configuration and cluster resources

func DeregisterERPCUpstream added in v0.3.2 

func DeregisterERPCUpstream(cfg *config.Config, networkType, id string) error

DeregisterERPCUpstream removes a previously registered local upstream from the eRPC ConfigMap.

func GetERPCStatus added in v0.5.0 

func GetERPCStatus(cfg *config.Config) (podStatus string, upstreamCounts map[int]int, err error)

GetERPCStatus returns eRPC pod status and upstream counts.

func Install 

func Install(cfg *config.Config, u *ui.UI, network string, overrides map[string]string, force bool) error

Install creates a network configuration by executing Go templates and saving to config directory

func List 

func List(cfg *config.Config, u *ui.UI) error

List displays all available networks from the embedded filesystem

func ListInstanceIDs added in v0.5.0 

func ListInstanceIDs(cfg *config.Config) ([]string, error)

ListInstanceIDs returns all installed network deployment identifiers (as "network/id" strings) by walking the networks directory on disk.

func RegisterERPCUpstream added in v0.3.2 

func RegisterERPCUpstream(cfg *config.Config, networkType, id string) error

RegisterERPCUpstream reads the deployed network's RPC endpoint and adds it as an upstream in the eRPC ConfigMap. The local node becomes the primary upstream (group: "primary") with automatic fallback to existing remote upstreams.

func RemovePublicRPCs added in v0.5.0 

func RemovePublicRPCs(cfg *config.Config, chainID int) error

RemovePublicRPCs removes all ChainList RPCs for a chain from the eRPC ConfigMap.

func ResolveChainID added in v0.5.0 

func ResolveChainID(nameOrID string) (int, string, error)

ResolveChainID converts a chain name or numeric string to a chain ID. Returns the chain ID and the resolved name (for display).

func ResolveInstance added in v0.5.0 

func ResolveInstance(cfg *config.Config, args []string) (identifier string, remaining []string, err error)

ResolveInstance determines which network deployment to target based on how many deployments are installed:

  • 0 deployments: returns an error prompting the user to install one
  • 1 deployment: auto-selects it, returns args unchanged
  • 2+ deployments: expects args[0] to be a known "network/id" identifier; consumes it from args and returns the rest. Errors if no match.

func SortByQuality added in v0.5.0 

func SortByQuality(endpoints []RPCEndpoint)

SortByQuality sorts RPC endpoints by tracking quality. Preference: tracking=none > tracking=limited > tracking=unknown > anything else.

func Sync 

func Sync(cfg *config.Config, u *ui.UI, deploymentIdentifier string) error

Sync deploys or updates a network configuration to the cluster using helmfile

func SyncAll added in v0.3.2 

func SyncAll(cfg *config.Config, u *ui.UI) error

SyncAll syncs all installed network deployments found in the config directory.

Types

type ArchiveScope added in v0.10.0 

type ArchiveScope struct {
	// Kind is one of: "all" (full archive from genesis), "before" (prune
	// before a specific block), "distance" (keep last N blocks of history).
	Kind string
	// Block is set when Kind == "before".
	Block uint64
	// Distance is set when Kind == "distance".
	Distance uint64
	// Label is a human-readable description for logs/picker confirmation.
	Label string
}

ArchiveScope is the resolved meaning of --since after parsing.

func ParseSince added in v0.10.0 

func ParseSince(raw string) (ArchiveScope, error)

ParseSince resolves a --since value into an ArchiveScope. Accepted forms:

  • "genesis", "all": full archive from genesis
  • "merge", "shanghai", "cancun", "prague", "osaka": EL hardfork name
  • "<N>d", "<N>mo", "<N>y": duration back from chain head (12s slots)
  • "<block>": raw block number (any unsigned integer)

Mode is reth-anchored: "before" presets get translated to reth's --prune.<segment>.before flags; "distance" presets to --prune.<segment>.distance.

type ChainEntry added in v0.5.0 

type ChainEntry struct {
	Name    string `json:"name"`
	Chain   string `json:"chain"`
	ChainID int    `json:"chainId"`
	RPC     []any  `json:"rpc"` // mix of strings and objects
}

ChainEntry represents a single chain entry from the ChainList API.

type ChainListFetcher added in v0.5.0 

type ChainListFetcher func() ([]byte, error)

ChainListFetcher abstracts the HTTP fetch so tests can inject fixtures.

type Hardfork added in v0.10.0 

type Hardfork struct {
	// Name is the canonical EL fork name used by --since=<name>.
	Name string
	// DisplayName is shown in the interactive picker.
	DisplayName string
	// Block is the first execution block at or after the fork activation.
	Block uint64
	// Date is the activation date, used only for picker labels.
	Date string
	// ApproxArchiveSizeTB is a rough estimate of mainnet archive disk usage
	// when pruning state history before this block (reth). Used in picker
	// labels so users have a realistic expectation. Values rounded.
	ApproxArchiveSizeTB float64
}

Hardfork describes a mainnet hardfork activation point used by the partial-archive picker. All block numbers are verified for Ethereum mainnet — paris from the reth chainspec source, post-merge forks from the beacon API by computing slot = (fork_ts - beacon_genesis) / 12 and reading execution_payload.block_number from the canonical block at (or shortly after) that slot.

Verified 2026-05-27 against:

  • reth v2.2.0 crates/chainspec/src/spec.rs (paris)
  • go-ethereum params/config.go (post-merge fork timestamps)
  • ethereum-beacon-api.publicnode.com (slot → execution block lookups)

func HardforkByName added in v0.10.0 

func HardforkByName(name string) *Hardfork

HardforkByName returns the hardfork with the given name, or nil.

type RPCEndpoint added in v0.5.0

func FetchChainListRPCs added in v0.5.0 

func FetchChainListRPCs(chainID int, fetcher ChainListFetcher) ([]RPCEndpoint, string, error)

func FilterFreeRPCs added in v0.5.0 

func FilterFreeRPCs(endpoints []RPCEndpoint) []RPCEndpoint

FilterFreeRPCs filters RPC endpoints to only include free, HTTPS, non-tracking endpoints.

func ParseAndFilterRPCs added in v0.5.0

ParseAndFilterRPCs parses ChainList JSON, finds the chain, filters and sorts RPCs. Exported for testing.

type RPCNetworkInfo added in v0.5.0 

type RPCNetworkInfo struct {
	ChainID   int
	Alias     string
	Upstreams []RPCUpstreamInfo
