Functions

func Recover

func Recover(signature ethereum.Signature, data []byte) (*ethereum.Address, error)

func Signature

func Signature(account *Account, data []byte) (ethereum.Signature, error)

Types

type Account

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

func NewAccount

func NewAccount(keyStorePath, passphrase string, address ethereum.Address) (*Account, error)

NewAccount returns a new Account instance.

func (*Account) Address

func (s *Account) Address() ethereum.Address

Address returns a address of this account.

func (*Account) Passphrase

func (s *Account) Passphrase() string

Passphrase returns a password of this account.

type Client

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

Client implements the ethereum.Client interface.

func NewClient

func NewClient(ethClient EthClient, signer pkgEthereum.Signer) *Client

NewClient returns a new Client instance.

func (*Client) Call

func (e *Client) Call(ctx context.Context, call pkgEthereum.Call) ([]byte, error)

Call implements the ethereum.Client interface.

func (*Client) MultiCall

func (e *Client) MultiCall(ctx context.Context, calls []pkgEthereum.Call) ([][]byte, error)

MultiCall implements the ethereum.Client interface.

func (*Client) SendTransaction

func (e *Client) SendTransaction(ctx context.Context, transaction *pkgEthereum.Transaction) (*pkgEthereum.Hash, error)

SendTransaction implements the ethereum.Client interface.

func (*Client) Storage

func (e *Client) Storage(ctx context.Context, address pkgEthereum.Address, key pkgEthereum.Hash) ([]byte, error)

Storage implements the ethereum.Client interface.

type ErrRevert

type ErrRevert struct {
	Message string
	Err     error
}

ErrRevert may be returned by Client.Call method in case of EVM revert.
