• +1. Deployed on Linea Sepolia.

• +2. Used as ERC-20 deposit token for Linea Sepolia RLN smart contract deployment.

@fryorcraken no specs, as this is a testnet-only arrangement, but I've added links to the other items in the checklist. I think this deliverable can now be closed. Also synced with js-waku re #341 which should be closeable soon, thus completing the milestone.
