CoApp
introduce yourself with onchain reputation
The problem CoApp solves
CoApp allows anyone to gain their first reputation onchain, adding AI assesments of their casts on Farcaster to an EAS schema on Base with over 66K attestations. The app also allows anyone to tag their friends with reputation, assisted by the AI. The economy of this is powered by CoDAO's CO token, which gives individuals and agents write access to the EAS social oracle.
CoApp supports and proves onchain reputation on Base, which is portable and supports contract level interactions with natural language context, web3 personas and global markers of value and appreciation.
Challenges I ran into
We had some problems with the Base App supporting all of the Mini App SDK features, but got through them. We relied on support from the Base team.
Smart Contract Address(es)
Our onchain interactions are with the Base EAS protocol (Ethereum Attestation Service)
Our Schema can be seen here on EAS

Other Onchain Proof
There are 66,000+ intereactions on the EAS schema since about 18 months ago. The CoApp mini app has added about 2K since we launched a few weeks ago.
