Functions

func OpenKeystore 

func OpenKeystore(dir string) *keystore.KeyStore

func StoredContracts 

func StoredContracts() map[string]StoredContract

Types

type Client 

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

func (Client) BalanceAt added in v0.5.0 

func (c Client) BalanceAt(ctx context.Context, address common.Address, blockHeight uint64) (*big.Int, error)

func (Client) BlockByHash 

func (c Client) BlockByHash(ctx context.Context, blockHash common.Hash) (*ethtypes.Block, error)

func (Client) DeployContract 

func (c Client) DeployContract(
	ctx context.Context,
	chainID *big.Int,
	contractAbi abi.ABI,
	bytecode,
	constructorInput []byte,
) (contractAddr common.Address, tx *ethtypes.Transaction, err error)

func (Client) ExecuteSmartContract 

func (c Client) ExecuteSmartContract(
	ctx context.Context,
	chainID *big.Int,
	contractAbi abi.ABI,
	addr common.Address,
	method string,
	arguments []any,
) (*etherumtypes.Transaction, error)

func (Client) FilterLogs 

func (c Client) FilterLogs(ctx context.Context, fq etherum.FilterQuery, currBlockHeight *big.Int, fn func(logs []ethtypes.Log) bool) (bool, error)

FilterLogs will gather all logs given a FilterQuery. If it encounters an error saying that there are too many results in the provided block window, then it's going to try to do this using a "binary search" approach while splitting the possible set in two, recursively.

func (Client) FindBlockNearestToTime added in v0.5.0 

func (c Client) FindBlockNearestToTime(ctx context.Context, startingHeight uint64, when time.Time) (uint64, error)

func (Client) TransactionByHash 

func (c Client) TransactionByHash(ctx context.Context, txHash common.Hash) (*ethtypes.Transaction, bool, error)

type CompassConsensus struct {
	Valset     CompassValset
	Signatures []*big.Int
	// contains filtered or unexported fields
}

func BuildCompassConsensus(
	ctx context.Context,
	v *types.Valset,
	signatures []chain.ValidatorSignature,
) CompassConsensus

func (CompassConsensus) OriginalSignatures added in v0.4.0 

func (c CompassConsensus) OriginalSignatures() [][]byte

type CompassValset added in v0.4.0

	QueryGetEVMValsetByID(ctx context.Context, id uint64, chainID string) (*types.Valset, error)
}
