BaseX smart contract

Running the code

• uses Truffle and Remix IDE
• git clone ...
• remixd -s . -u https://remix.ethereum.org/

Integration with Kleros

Creating a proxy contract that has single purpose: INTEGRATION WITH KLEROS

Kleros parameters

Defaults as much as possible, convention over configuration.

Reasonably low deposit (so that it is not a barrier to entry)

Deployment launch sequence

• Deploy list of organisations to Kleros in their UI: https://curate.kleros.io/factory (Is this a list of lists? YES)
• Add the newly created list to global "list of lists" in Kleros UI
• Save the address of the list to: migrations/1_deploy_upgradeable.js

LAUNCH CHECKLIST

• 1. Deploy BaseX, following the instructions from: https://forum.openzeppelin.com/t/openzeppelin-upgrades-step-by-step-tutorial-for-truffle/3579
  • npx truffle migrate --network goerli (need to delete previous build files, or move to a sepate folder, see deployment_logs)
  • truffle run verify BaseX --network goerli
• 2A. Deploy PVT NVT (passing address of BaseX to grant roles). This can happen via remix: remixd -s . -u https://remix.ethereum.org/ (verification can happen via remix Etherescan plugin)
• 2B. If already deployed - update the BaseX (the proxy) on these contracts to grant required roles. Note that at some point (old version which is now staging) were using 0x85 address, not the MetaMask2 (which is the current deployer of other contracts)
• 3. Set PVT NVT address at BaseX
• 4. On the front-end update contract address and ABI
• 5. On the back-end (now we have Express backend) update contract address and ABI

If KlerosProxy updates, we can reuse existing PVT NVT contracts, there is a convenient method updateBaseX that will grant minting / burning roles. — we are using upgradeable contracts, the BaseX address will stay the same

UPGRADE CHECKLIST:

1. Create a new file BaseXV4.sol
2. NICE TO HAVE Use OpenZeppelin plugin to ensure that the new contract is compatible with the old one
3. Deploy the new contract using Remix
4. Verify the new contract on Etherscan
5. Update the proxy admin to point to the new contract
6. Update the ABI in front-end
7. Update the readme below with latest implementation address
