// Package bind implements utilities for interacting with Solidity contracts

|

|
// methods for calling/transacting, filtering chain history for

|
// specific custom Solidity event types, creating event subscriptions to
|
||||||
|
// monitor the chain for event occurrences.

// Two methods for contract deployment are provided:
|
||||||
|
// - DeployContract is intended to be used for deployment of a single contract.
|
||||||
|
// - LinkAndDeploy is intended to be used for the deployment of multiple
|
||||||
|
// contracts, potentially with library dependencies.
