Adora.Promo is an on-chain social media advertising marketplace leveraging AI to secure deals between advertisers and creators. I built all of the platform's smart contracts using Solidity, Hardhat, and Javascript. Our biggest challenges were: * ensuring that users can remain anonymous as everything on EVM blockchains is publicly visible * managing a tight project deadline How we overcame them: * reduced the project scope to only crucial features * used client-side encryption and Sismo ZK account ownership proofs to ensure user anonymity I learned to: * use Chainlink functions * integrate Tableland into smart contracts * work in a web3 team (communication and managing a tight deadline)
