Olympus V3

Olympus V3, aka Bophades, is the latest iteration of the Olympus protocol. It is a foundation for the future of the protocol, utilizing the Default Framework to allow extensibility at the base layer via fully onchain governance mechanisms.

Use pnpm run build to refresh deps.

Set up a foundry config in foundry.toml.

Deployments

Up-to-date addresses of all the deployments can be found in:

Privileged Testnet Accounts (Multi-sigs)

Setup

Add FORK_TEST_RPC_URL to the .env file in order to run fork tests

Copy the .env.deploy.example file into one file per chain, e.g. .env_deploy_goerli and set the appropriate variables. This chain-specific environment file can then be called during deployment, e.g. env $(cat .env_deploy_goerli | xargs) PRIVATE_KEY=<PRIVATE KEY> ./shell/deploy.sh

How To Deploy

  1. Update the solidity deployment script src/scripts/deployment/DeployV2.sol.
    • If necessary, add external dependencies (e.g. sdai = ERC20(envAddress("external.tokens.sDAI"));)
    • Create a function to handle the deployment of the new contracts (e.g. _deployBLVaultLusd())
    • Add the new contracts to the selectorMap with their corresponding keys.
  2. Update the configuration-input JSON file src/scripts/deployment/deploy.json
    • Use the corresponding keys for the selectorMap in #1.3.
    • Use any necessary configuration parameters.
    • Create a copy the file under src/scripts/deploy/savedDeployments/ and give it the same name as internal function created in #1.2.
  3. If external dependencies are required, add them in src/scripts/env.json, so that they can be used in DeployV2.sol.
  4. If necessary, update your .env file. It should, at least, have the same variables as in .env.deploy.example.
  5. Run shell/deploy.sh $DEPLOY_FILE_PATH to run the deployment shell script (e.g. shell/deploy.sh src/scripts/deploy/savedDeployments/rbs_v1_3.json).
    • If you want to broadcast the tx to the network, uncomment the line of the script containing --broadcast. Only do so after having tested the deployment.
  6. After a successful deployment, update src/scripts/env.json with the new contract addresses.
  7. Finally, use olymsig (or olymsig-testnet if testing the deployment) to plug the newly deployed contracts into olympus-v3.

How To Verify

Sometimes the automatic etherscan verification fails when deploying a contract. If that's the case, follow the these steps to verify existing contracts:

  1. Execute the shell/verify_etherscan.sh script with the following arguments:

    • CONTRACT_ADDRESS: Address of the target contract to be verified.
    • CONTRACT_PATH: Relative path to the target contract.
    • CONSTRUCTOR_ARGS: Calldata of the constructor args. The preferred method is to manually encode the data, but cast abi-encode "constructor(args)" "values" can also be used.

  2. This is an example execution of the shell script:

    shell/verify_etherscan.sh 0x0AE561226896dA978EaDA0Bec4a7d3CfAE04f506 src/policies/Operator.sol:Operator 0x0000000000000000000000002286d7f9639e8158fad1169e76d1fbc38247f54b000000000000000000000000007f7a1cb838a872515c8ebd16be4b14ef43a22200000000000000000000000073df08ce9dcc8d74d22f23282c4d49f13b4c795e00000000000000000000000064aa3364f17a4d01c6f1751fd97c2bd3d7e7f1d50000000000000000000000006b175474e89094c44da98b954eedeac495271d0f00000000000000000000000083f20f44975d03b1b09e64809b757c47f942beea0000000000000000000000000000000000000000000000000000000000000bb8000000000000000000000000000000000000000000000000000000000003f48000000000000000000000000000000000000000000000000000000000000186a0000000000000000000000000000000000000000000000000000000000000384000000000000000000000000000000000000000000000000000000000000003e8000000000000000000000000000000000000000000000000000000000007e90000000000000000000000000000000000000000000000000000000000000000120000000000000000000000000000000000000000000000000000000000000015

    Where the CONSTRUCTOR_ARGS have been decode in the following way:

    constructor(address,address,address,uint256,uint256[2],uint256[2])"
