Types ¶

type BackendClient ¶

type BackendClient interface {
	ChainID(ctx context.Context) (*big.Int, error)
	CallContract(ctx context.Context, call ethereum.CallMsg, blockNumber *big.Int) ([]byte, error)
	PendingNonceAt(ctx context.Context, account common.Address) (uint64, error)
	SuggestGasPrice(ctx context.Context) (*big.Int, error)
	SuggestGasTipCap(ctx context.Context) (*big.Int, error)
	EstimateGas(ctx context.Context, call ethereum.CallMsg) (gas uint64, err error)
	SendTransaction(ctx context.Context, tx *types.Transaction) error
	TransactionByHash(ctx context.Context, hash common.Hash) (*types.Transaction, bool, error)
	BalanceAt(ctx context.Context, address common.Address, block *big.Int) (*big.Int, error)
}

type Key ¶

type Key string

func GenerateKey ¶

func GenerateKey() (Key, error)

func (Key) PrivateECDSA ¶

func (k Key) PrivateECDSA() (*ecdsa.PrivateKey, error)

func (Key) PublicAddress ¶

func (k Key) PublicAddress() (common.Address, error)

func (Key) PublicECDSA ¶

func (k Key) PublicECDSA() (*ecdsa.PublicKey, error)

type Option ¶ added in v0.4.0

type Option func(*options)

Option configures a Wallet.

func WithLookup ¶ added in v0.4.0

func WithLookup(timeout, interval time.Duration) Option

WithLookup sets how long, and how often, the chain is asked for a transaction whose send failed before the send is reported as failed. The defaults are 15s and 1s. A timeout at or below zero uses the default, an interval at or below zero asks once. Some nodes reject a transaction they did keep, e.g. Nethermind answers "replacement transaction underpriced" for one already in its pool.

func WithRetry ¶ added in v0.4.0

func WithRetry(retries int, delay time.Duration) Option

WithRetry sets how many times a failed send is retried, waiting delay between attempts. The default is 0, which sends once; negative values count as 0. Every attempt re-sends the same signed transaction, so at most one can be mined. A transaction the node rejected is not retried.

type Token ¶

type Token struct {
	Contract common.Address
	Symbol   string
	Decimals int
}

func NativeCoinForChain ¶

func NativeCoinForChain(cid int64) (Token, error)

func SwarmTokenForChain ¶

func SwarmTokenForChain(cid int64) (Token, error)

type TokenInfoGetterFn ¶

		toAddr common.Address,
		amount *big.Int,
		token Token,
	) error
}

type TransactionSender ¶

type TransactionSender interface {
	Send(
		ctx context.Context,
		toAddr common.Address,
		amount *big.Int,
		callData []byte,
	) error
}
