POOL-2139 Avalanche: Deploy RNG Chainlink 2.0 on Avalanche

Chainlink VRF 2.0 Docs: https://docs.chain.link/docs/vrf-contracts/

Interface: https://vrf.chain.link/

BLOCKERS

Chainlink VRF 2.0 needs to be deployed on Avalanche.

The Chainlink VRF interface need to be available for the Avalanche network.

TODO

• Create a subscription through the Chainlink VRF interface

• Fund this subscription with LINK tokens

• Update the v4-mainnet deployment scripts to deploy the RNG Chainlink v2.0 contract: https://github.com/pooltogether/pooltogether-rng-contracts/blob/master/contracts/RNGChainlinkV2.sol

  • add the following code to deploy/v1.3.0/avalanche.ts

    await deployAndLog('RNGChainlinkV2', {
        from: deployer,
        args: [
    	  deployer,
          0x6168499c0cFfCaCD319c818142124B7A15E857ab, // VRF Coordinator address on Rinkeby
          1, // Id of the subscription that was created through the interface
          0xd89b2bf150e3b9e13446986e571fb9cab24b13cea0a43ea20a6049a85cc807cc, // 30 gwei key hash gas lane for Rinkeby
    		],
        skipIfAlreadyDeployed: true,
      });
    
    await setManager('RNGChainlinkV2', null, drawBeaconResult.address);
    

• Update the v4-mainnet deployment scripts to deploy the DrawBeacon contract:

  • add the following code to deploy/v1.3.0/avalanche.ts

    const rngService = await ethers.getContract('RNGChainlinkV2');
    
    // Should be in sync with DrawBeacon on Mainnet
    const drawBeaconResult = await deployAndLog('DrawBeacon', {
        from: deployer,
        args: [
          deployer,
          drawBuffer.address,
          rngService.address,
    	  // We can call the getNextDrawId on DrawBeacon Mainnet contract to determine this value.
          1, // Starting DrawID
          // We can call the calculateNextBeaconPeriodStartTimeFromCurrentTime on DrawBeacon Mainnet contract to determine this value.
          BEACON_START_TIME,
          BEACON_PERIOD_SECONDS, // 86400 = one day
          RNG_TIMEOUT_SECONDS // 2 * 3600 = 2 hours
        ],
        skipIfAlreadyDeployed: true,
      });
    

• Add v1.3.0 commands to test, deploy and verify

• Test the deployment script: test:v1.3.0.avalanche

• Run the deployment script: deploy:v1.3.0.avalanche

• Verify the contract on Snowtrace: avalanche

• Update the manager on the DrawBuffer contract to be the DrawBeacon contract

• Set the newly deployed RNG Chainlink V2 contract as a consumer of the Chainlink VRF subscription

• Don't forget to release a new version of v4-mainnet package afterwards, this package should include the new deployment artifacts
