Types

type Client

type Client struct {
	CallContractF func(call ethereum.CallMsg) ([]byte, error)
	CodeAtMap     map[common.Address]bool
}

func (*Client) BlockNumber

func (c *Client) BlockNumber(ctx context.Context) (uint64, error)

func (*Client) CallContract

func (c *Client) CallContract(ctx context.Context, call ethereum.CallMsg, blockNumber *big.Int) ([]byte, error)

CallContract executes an Ethereum contract call with the specified data as the input.

func (*Client) ChainID

func (c *Client) ChainID(ctx context.Context) (*big.Int, error)

func (*Client) CodeAt

func (c *Client) CodeAt(ctx context.Context, contract common.Address, blockNumber *big.Int) ([]byte, error)

func (*Client) EstimateGas

func (c *Client) EstimateGas(ctx context.Context, call ethereum.CallMsg) (gas uint64, err error)

EstimateGas tries to estimate the gas needed to execute a specific transaction based on the current pending state of the backend blockchain. There is no guarantee that this is the true gas limit requirement as other transactions may be added or removed by miners, but it should provide a basis for setting a reasonable default.

func (*Client) FilterLogs

func (c *Client) FilterLogs(ctx context.Context, query ethereum.FilterQuery) ([]types.Log, error)

FilterLogs executes a log filter operation, blocking during execution and returning all the results in one batch.

TODO(karalabe): Deprecate when the subscription one can return past data too.

func (*Client) HeaderByNumber

func (c *Client) HeaderByNumber(ctx context.Context, number *big.Int) (*types.Header, error)

func (*Client) PendingCodeAt

func (c *Client) PendingCodeAt(ctx context.Context, account common.Address) ([]byte, error)

PendingCodeAt returns the code of the given account in the pending state.

func (*Client) PendingNonceAt

func (c *Client) PendingNonceAt(ctx context.Context, account common.Address) (uint64, error)

PendingNonceAt retrieves the current pending nonce associated with an account.

func (*Client) SendTransaction

func (c *Client) SendTransaction(ctx context.Context, tx *types.Transaction) error

SendTransaction injects the transaction into the pending pool for execution.

func (*Client) SubscribeFilterLogs

func (c *Client) SubscribeFilterLogs(ctx context.Context, query ethereum.FilterQuery, ch chan<- types.Log) (ethereum.Subscription, error)

SubscribeFilterLogs creates a background log filtering operation, returning a subscription immediately, which can be used to stream the found events.

func (*Client) SuggestGasPrice

func (c *Client) SuggestGasPrice(ctx context.Context) (*big.Int, error)

SuggestGasPrice retrieves the currently suggested gas price to allow a timely execution of a transaction.

func (*Client) SuggestGasTipCap

func (c *Client) SuggestGasTipCap(ctx context.Context) (*big.Int, error)

SuggestGasTipCap retrieves the currently suggested 1559 priority fee to allow a timely execution of a transaction.
