Class Instantiation
Importing a Contract Class and making it your own
import { ComptrollerLib } from '@enzymefinance/protocol'
Next, instantiate a new class by passing it two parameters:
- 1.The
addressat which the contract is located on chain. Vault-specific contract addresses are available on the Vault's overview page on the Enzyme app. Non vault-specific contract addresses can be found here. - 2.A
Signerobject. A Signer is a class imported fromethersand instantiated per their documentation. It describes the user on whose behalf the contract is being instantiated (and who will eventually call any methods on the class) and a connection to an Ethereum node.
Ethers provides a good description of the
Signer object, and it's beyond the scope of this document to go into more detail. You can see an example of how a signer object is instantiated and passed to an Enzyme class in practice in the example Enzyme Bot repo and accompanying blog post.const address = '0xw23r...' // for example only
const signer = new Signer(privateKey, ethNodeAddress) // for example only
const vaultComptroller = new ComptrollerLib(address, signer)
