DAOsign: On-Chain Attestation Middleware
DAOsign is a web3 middleware platform enabling on-chain attestation issuance.
DAOsign is a web3 middleware platform enabling on-chain attestation issuance.
DAOsign began as an internal research initiative to explore a trustless alternative to traditional electronic signatures. Over time, it evolved into a modular attestation middleware designed to bridge verified off-chain data with blockchain-native proofs.
This internal venture allowed us to experiment, ship production-grade components, secure ecosystem grants, and develop deep expertise in on-chain attestations, identity verification, and privacy-preserving infrastructure.
We built a trustless document signing solution using cryptographic proofs, wallet-based identity, and content hashing (CID). Each signing event generates three verifiable proofs — Proof of Signature, Proof of Authority, Proof of Agreement, and Proof of Identity — forming a complete on-chain alternative to traditional e-signatures.
This evolved into a modular Attestation Service that bridges off-chain data with blockchain-verifiable outputs: on-chain proofs, Verifiable Credentials, NFT attestations, and E-Sign/UETA-compliant documents — all returned as DIDs for third-party validation.
Secured grants from Oasis, Polkadot, and others. Integrated EVM chains, Polkadot (Ink!), and partial NEAR support, with privacy enhancements via Oasis Sapphire.
Solidity / Rust (Ink!), React / Next.js, TypeScript SDKs. Core protocol is production-ready and modular.
Through DAOsign, we secured multiple ecosystem grants, built and tested multi-chain attestation flows, and built deep hands-on experience in on-chain attestations, identity proofs, and verifiable data issuance.
