Researched signs technical foundation and found interesting infrastructure details.
Sign leverages EAS (ethereum attestation service) which has hardcore development standards:
100% test coverage across all smart contracts
audited by spearbit (top security firm)
active github with multiple SDK versions
eas contracts breakdown From github:
EAS.sol: 100% coverage
SchemaRegistry.sol: 100% coverage
EIP1271Verifier.sol: 100% coverage
Resolver contracts: 100% coverage
why this matters:
most defi protocols have 70-80% test coverage, 100% is rare and shows serious engineering
eas supports both onchain and offchain attestations - sign uses this flexibility for government-scale deployments
technical architecture sign
uses:
schema registration contract (defines credential structure)
attestation contract (creates verifiable claims)
resolver contracts (advanced logic like payments)
the $4B tokentable distribution ran on this battle-tested infrastructure
compared to competitors building custom attestation systems from scratch, sign chose proven foundation
eas github activity shows:
regular updates to eas-sdk
rust SDK for performance-critical apps
offchain attestation versioning (privacy focus)
indxing services for query speed
sign layered their
$SIGN token economy on top of eas technical foundation - smart move separating infrastructure from tokenomics
institutional custody ($343M coinbase prime) makes sense when you see engineering quality underneath
no token for EAS itself - remains credibly neutral infrastructure, sign monetizes through
$SIGN governance token.
