Types

type LocalRelayer

type LocalRelayer struct {
	Sender *ethwallet.Wallet
}

LocalRelayer is a simple implementation of a relayer which will dispatch meta transactions locally. This should only be used for testing / debugging, and never seriously in a real app.

func NewLocalRelayer

func NewLocalRelayer(sender *ethwallet.Wallet) (*LocalRelayer, error)

func (*LocalRelayer) EstimateGasLimits

func (r *LocalRelayer) EstimateGasLimits(ctx context.Context, walletConfig sequence.WalletConfig, walletContext sequence.WalletContext, txns sequence.Transactions) (sequence.Transactions, error)

func (*LocalRelayer) GetNonce

func (r *LocalRelayer) GetNonce(ctx context.Context, walletConfig sequence.WalletConfig, walletContext sequence.WalletContext, space *big.Int, blockNum *big.Int) (*big.Int, error)

func (*LocalRelayer) GetProvider

func (r *LocalRelayer) GetProvider() *ethrpc.Provider

func (*LocalRelayer) Relay

func (r *LocalRelayer) Relay(ctx context.Context, signedTxs *sequence.SignedTransactions) (sequence.MetaTxnID, *types.Transaction, ethtxn.WaitReceipt, error)

func (*LocalRelayer) Wait

func (r *LocalRelayer) Wait(ctx context.Context, metaTxnID sequence.MetaTxnID, optTimeout *time.Duration) (sequence.MetaTxnStatus, *types.Receipt, error)

type RpcRelayer

type RpcRelayer struct {
	Service proto.Relayer
	// contains filtered or unexported fields
}

func NewRpcRelayer

func NewRpcRelayer(provider *ethrpc.Provider, rpcRelayerURL string, httpClient proto.HTTPClient) (*RpcRelayer, error)

func (*RpcRelayer) EstimateGasLimits

func (r *RpcRelayer) EstimateGasLimits(ctx context.Context, walletConfig sequence.WalletConfig, walletContext sequence.WalletContext, txns sequence.Transactions) (sequence.Transactions, error)

..

func (*RpcRelayer) GetNonce

func (r *RpcRelayer) GetNonce(ctx context.Context, walletConfig sequence.WalletConfig, walletContext sequence.WalletContext, space *big.Int, blockNum *big.Int) (*big.Int, error)

NOTE: nonce space is 160 bits wide

func (*RpcRelayer) GetProvider

func (r *RpcRelayer) GetProvider() *ethrpc.Provider

func (*RpcRelayer) Relay

func (r *RpcRelayer) Relay(ctx context.Context, signedTxs *sequence.SignedTransactions) (sequence.MetaTxnID, *types.Transaction, ethtxn.WaitReceipt, error)

Relay will submit the Sequence signed meta transaction to the relayer. The method will block until the relayer responds with the native transaction hash (*types.Transaction), which means the relayer has submitted the transaction request to the network. Clients can use WaitReceipt to wait until the metaTxnID has been mined.

func (*RpcRelayer) Wait

func (r *RpcRelayer) Wait(ctx context.Context, metaTxnID sequence.MetaTxnID, optTimeout *time.Duration) (sequence.MetaTxnStatus, *types.Receipt, error)
