How to deploy/upgrade proxy through TypeChain?

atom · August 16, 2021, 11:40am

With regular non-upgradeable contracts, the generated Typescript files from Typechain can be used to directly deploy a contract through the ContractFactory using its deploy function.

However, when using an upgradeable contract, the files generated from TyepChain doesn't have deployProxy and upgradeProxy. I have to go back to the upgrades module from the hardhat-upgrades plugin to deploy through hardhat.

Is there a way to deploy/upgrade an upgradeable contract and its proxy through TypeChain so that the whole process can be done in Typescript?

It is not possible to deploy the proxy through TypeChain directly. You need to use deployProxy.

Also keep in mind that there is a bug where a TypeChain Factory will not type as the argument to deployProxy.

This adds a generic to the return result of the DeployFunction. This allows bett…er integration with Typechain types, like so: ```ts const WhitelistFactory = await hre.ethers.getContractFactory('Whitelist'); // Notice the `: Whitelist` here, which casts the Contract return to the Typechain const whitelist: Whitelist = await hre.upgrades.deployProxy(WhitelistFactory, [args.address]); await whitelist.deployed(); // We could then use custom RPC methods on Whitelist and have it fully typechecked here. ```

But I still encourage you to go ahead and find a way, I'm sure there is a workaround, and please share with us!
