Types

type Connection

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

func NewConnection

func NewConnection(endpoint string, http bool, kp *secp256k1.Keypair, log log15.Logger, gasLimit, gasPrice *big.Int, gasMultiplier *big.Float, gsnApiKey, gsnSpeed string) *Connection

NewConnection returns an uninitialized connection, must call Connection.Connect() before using.

func (*Connection) CallOpts

func (c *Connection) CallOpts() *bind.CallOpts

func (*Connection) Client

func (c *Connection) Client() *ethclient.Client

func (*Connection) Close

func (c *Connection) Close()

Close terminates the client connection and stops any running routines

func (*Connection) Connect

func (c *Connection) Connect() error

Connect starts the ethereum WS connection

func (*Connection) EnsureHasBytecode

func (c *Connection) EnsureHasBytecode(addr ethcommon.Address) error

EnsureHasBytecode asserts if contract code exists at the specified address

func (*Connection) EstimateGasLondon

func (c *Connection) EstimateGasLondon(ctx context.Context, baseFee *big.Int) (*big.Int, *big.Int, error)

func (*Connection) Keypair

func (c *Connection) Keypair() *secp256k1.Keypair

func (*Connection) LatestBlock

func (c *Connection) LatestBlock() (*big.Int, error)

LatestBlock returns the latest block from the current chain

func (*Connection) LockAndUpdateOpts

func (c *Connection) LockAndUpdateOpts() error

LockAndUpdateOpts acquires a lock on the opts before updating the nonce and gas price.

func (*Connection) Opts

func (c *Connection) Opts() *bind.TransactOpts

func (*Connection) SafeEstimateGas

func (c *Connection) SafeEstimateGas(ctx context.Context) (*big.Int, error)

func (*Connection) UnlockOpts

func (c *Connection) UnlockOpts()

func (*Connection) WaitForBlock

func (c *Connection) WaitForBlock(targetBlock *big.Int, delay *big.Int) error

WaitForBlock will poll for the block number until the current block is equal or greater. If delay is provided it will wait until currBlock - delay = targetBlock
