Contracts

The usual way to deploy a contract with the geth library is to use abigen with the provided --bin option, which generates a function that deploys the smart contract. Since the deployment of a smart contract requires an EIP-712 transaction, the deployment function generated with the abigen tool does not work. In this matter, the Deploy interface is created, which provides methods for the deployment of smart contracts and smart accounts. There are the following objects that implement the Deploy interface:

• BaseDeployer,
• Wallet.

Contract instantiation is the same as in the geth library. For examples of how to deploy and instantiate contracts and accounts, refer to the following:

• Deploy smart contracts using CREATE method.
• Deploy smart contracts using CREATE2 method.
• Deploy smart accounts using CREATE method.
• Deploy smart accounts using CREATE2 method.
