Functions

func ActionTypeString added in v1.19.0 

func ActionTypeString(act action.Action) string

ActionTypeString names an action for the indexes that record a type column.

It lives here because two plugins — block_action and block_action_partition — both need it and both used to carry their own copy. When the reward grants were split into three types, only one copy was updated, and the API reads the other table: the explorer went on showing every IIP-59 voter payout as a generic "grantReward" even though the fix was in.

func ChainClient 

func ChainClient() iotexapi.APIServiceClient

func ChainClientWithEndPoint added in v1.4.0 

func ChainClientWithEndPoint(endpoint string, withInsecure bool) (iotexapi.APIServiceClient, error)

func CheckInterfaceID added in v1.8.20 

func CheckInterfaceID(addr string, interfaceID [4]byte) (bool, error)

func ComputeAuthorizationValidity added in v1.18.2 

func ComputeAuthorizationValidity(
	ctx context.Context,
	authority common.Address,
	blockHeight uint64,
	chainID *uint256.Int,
	authNonce uint64,
) (bool, error)

ComputeAuthorizationValidity evaluates whether an EIP-7702 authorization would have been accepted by the chain at the time it was included.

Validity rules (mirroring iotex-core's validateAuthorization):

  1. chain_id is 0 or matches the network chain id
  2. authority's code at blockHeight-1 is empty OR a delegation designator
  3. authority's nonce at blockHeight-1 equals authNonce

The blacklist rule is intentionally skipped. Signature recovery is the caller's responsibility (the recovered authority is an input).

Returns:

  • (true, nil) if all rules pass
  • (false, nil) if any rule failed for a deterministic reason
  • (false, err) only when RPC could not reach a decision after retries

func EthArchiveClient added in v1.18.2 

func EthArchiveClient() (*ethclient.Client, error)
