How to deploy MIM OFT

For SPELL OFT, replace MIMOFT with SpellOFT in the commands below and use the configuration in layerzero.spell.config.ts instead of layerzero.mim.config.ts.

1. Deploy FeeHandler

Can be reused for both MIM and SPELL OFT.

Edit deploy/FeeHandler.ts and update configurations with the right values for the network you are deploying to.

bunx hardhat deploy --network <network-name> --tags FeeHandler

2. Deploy MIMOFT

be sure to update the owner of the MIMOFT to the multisig address

bunx hardhat lz:deploy --tags MIMOFT --networks <network-name>

Rename the DefaultProxyAdmin file to MIMOFT_ProxyAdmin

3. Verify

bunx hardhat etherscan-verify --network <network-name>

On Hyperliquid it should be sourcify:

bunx hardhat sourcify --endpoint "https://sourcify.parsec.finance"

4. Change Endpoint Delegate To Owner

endpoints: https://docs.layerzero.network/v2/deployments/deployed-contracts

cast --rpc-url <url> send <oft proxy address> "setDelegate(address)" <owner address>

Double check the delegate is set to the owner.

cast --rpc-url <url> call <layer zero endpoint> "delegates(address)(address)" <oft address>

5. Change OFT Ownership

bunx hardhat lz:ownable:transfer-ownership --oapp-config layerzero.mim.config.ts

Double check the owner is the safe address.

cast --rpc-url <url> call <oft proxy address> "owner()(address)"

6. Change Proxy Admin Ownership

cast --rpc-url <url> send <MIMOFT_ProxyAdmin address> "transferOwnership(address)" <safe address>

Double check the owner is the safe address.

cast --rpc-url <url> call <MIMOFT_ProxyAdmin address> "owner()(address)"

7. Review

Ask the team to review the deployment.

8. LayerZero Wiring

be sure the safe api endpoint is the right transaction api one. For example, appending /api/v1/safes/<safe address>/ should not fail.

bunx hardhat lz:oapp:wire --oapp-config layerzero.mim.config.ts --safe
