OHM (and associated contracts) may need to be deployed on testnets. If so, this document can help with the steps.

1. Check out the olympus-contracts repo.

2. In the olympus-contracts repo:

   1. Install dependencies: yarn install
   2. Compile contracts: yarn run compile
   3. Set up the environment (using .env.sample)
   4. Ensure that hardhat.config.ts has the testnet defined
   5. Run yarn run deploy:<network> to deploy
   6. Run yarn run etherscan:<network> to verify on Etherscan

3. Record the addresses in scripts/env.json

After this, the Bophades stack can be deployed (e.g. using shell/L2/deploy.sh).

Update env.json with the addresses.

Then run ./shell/L2/grantRoles.sh.

The following are also likely to be required (deployment and installation):

• Clearinghouse Registry
• Clearinghouse

Run mint() in DeployUsdsMocks.sol

Grant the minter admin role:

./shell/roles/grantRole.sh --role minter_admin --to <address> --chain <chain> --account <wallet> --broadcast true

Add a minting category:

./shell/mint/addCategory.sh --category test --chain <chain> --account <wallet> --broadcast true

Mint OHM:

./shell/mint/mint.sh --to <recipient> --amount <amount> --category test --chain <chain> --account <wallet> --broadcast true

Run ./shell/mint/stakeToGOhm.sh.
