V4 Timelocks Contracts

Tests Coverage Status built-with openzeppelin GPLv3 license


Timelock contracts assist with Phase 1 in the roll-out of V4. Granting authority to the operations teams to prevent a "bad actor" oracle from incorrectly setting a draw or prize distribution params.


The DrawCalculatorTimelock adds a timelock for PrizeDistributor to execute a claim with the most recently pushed PrizeDistribution params pushed.

L1TimelockTrigger & L2TimelockTrigger

Both L1TimelockTrigger/L2TimelockTrigger contracts set a timelock or a "cooldown" period in the linked DrawCalculatorTimelock contract. The DrawCalculatorTimelock routes calculate execution through a DrawCalculator contract for the linked PrizeDistributor contract.


The L1TimelockTrigger contract pushes DrawLib.Draw and DrawLib.PrizeDistribution params onto the DrawBuffer and PrizeDistributionBuffer contracts.


The L2TimelockTrigger pushes DrawLib.PrizeDistribution params onto a PrizeDistributionBuffer contract.


Getting Started

The project is made available as a NPM package.

$ yarn add @pooltogether/pooltogether-contracts

The repo can be cloned from Github for contributions.

$ git clone
$ yarn

We use direnv to manage environment variables. You'll likely need to install it.

cp .envrc.example .envrc

To run fork scripts, deploy or perform any operation with a mainnet/testnet node you will need an Infura API key.


We use Hardhat and hardhat-deploy

To run unit & integration tests:

$ yarn test

To run coverage:

$ yarn coverage

Fork Testing

Ensure your environment variables are set up. Make sure your Alchemy URL is set. Now start a local fork:

$ yarn start-fork

Setup account impersonation and transfer eth:

$ ./scripts/


Deploy Locally

Start a local node and deploy the top-level contracts:

$ yarn start

NOTE: When you run this command it will reset the local blockchain.
