Functions

func AddCustomRPC added in v0.8.1 

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 v0.8.1 

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 DefaultChainListFetcher added in v0.8.1 

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 

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

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

func GetERPCStatus added in v0.8.1 

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 v0.8.1 

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 

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 v0.8.1 

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

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

func ResolveChainID added in v0.8.1 

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 v0.8.1 

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 v0.8.1 

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 

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

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

Types

type ChainEntry added in v0.8.1 

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 v0.8.1 

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

ChainListFetcher abstracts the HTTP fetch so tests can inject fixtures.

type RPCEndpoint added in v0.8.1 

type RPCEndpoint struct {
	URL      string `json:"url"`
	Tracking string `json:"tracking"` // "none", "limited", or "yes"
}

RPCEndpoint represents a single RPC endpoint from ChainList.

func FetchChainListRPCs added in v0.8.1 

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

FetchChainListRPCs fetches RPCs for a given chain ID from ChainList, filters for free/public HTTPS endpoints, and returns up to maxRPCs sorted by quality (tracking=none preferred over tracking=limited).

func FilterFreeRPCs added in v0.8.1 

func FilterFreeRPCs(endpoints []RPCEndpoint) []RPCEndpoint

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

func ParseAndFilterRPCs added in v0.8.1 

func ParseAndFilterRPCs(data []byte, chainID, maxRPCs int) ([]RPCEndpoint, string, error)

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

type RPCNetworkInfo added in v0.8.1 

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

RPCNetworkInfo represents a network (chain) configured in eRPC.

func ListRPCNetworks added in v0.8.1 

func ListRPCNetworks(cfg *config.Config) ([]RPCNetworkInfo, error)

ListRPCNetworks reads the eRPC ConfigMap and returns configured networks with their upstreams.

type RPCUpstreamInfo added in v0.8.1 

type RPCUpstreamInfo struct {
	ID       string
	Endpoint string
	ChainID  int
}

RPCUpstreamInfo represents an upstream in the eRPC config for display.

type TemplateField
