Thanks to EAS there can be a chain of schemas off-chain up until the last attestation of the completion of the match is on-chain here is an example: https://x.com/ludus_eth/status/1744415413285327064?s=20 .
However now I face a problem with the SDK: https://github.com/ethereum-attestation-service/eas-sdk . Its only in ts/js so i cannot call it directly from the custom function in dart, i undrstand there is a web 3 package built in pub.dev but only for reading smart contracts through a client which i dont want to, i also know there is a way to wrap the SDK into dart but im open to any suggestions.
