Battle-Tested Technology Using Industry Standards

When evaluating blockchain infrastructure, enterprises face a critical question: are we betting on experimental technology that might not exist in five years, or on established standards with proven track records?

Integra is built entirely on industry standards. We didn't invent new cryptography, create proprietary token formats, or build isolated infrastructure. Every component uses battle-tested technology from the most trusted names in blockchain.

The Standards Advantage

Interoperability: Standard tokens work with every wallet, marketplace, and DeFi protocol. No integration work required—if it supports ERC-721, it supports Integra tokens.

Security Audits: We leverage libraries that have been audited by the industry's top security firms and battle-tested in production managing billions of dollars. Coinbase's MPC library, Ethereum's EAS, and ERC token standards have collective security investment we couldn't replicate alone.

Developer Familiarity: Developers who know Solidity, ERC standards, and Ethereum tooling can build on Integra immediately. No proprietary learning curve.

Future-Proofing: Standards evolve with the ecosystem. When EIP improvements are adopted, Integra benefits automatically. We're not locked into deprecated approaches.

The Standards We Build On

Component	Standard	Origin
Key Management	2-party ECDSA	Coinbase cb-mpc
Document Identity	SHA-256	NIST
Attestations	EAS	Ethereum Attestation Service
Tokens	ERC-721, 1155, 20	Ethereum Foundation
Vaults	ERC-4626	Ethereum Foundation
Security Tokens	ERC-3643, ERC-1400	T-REX, Polymath

Token Standards Implementation

All Integra tokenizers extend OpenZeppelin base contracts:

// OwnershipTokenizer extends ERC-721
contract OwnershipTokenizer is ERC721, ITokenizer {
    mapping(uint256 => bytes32) private _integraHashes;

    function getDocumentHash(uint256 tokenId) public view returns (bytes32) {
        return _integraHashes[tokenId];
    }
}

The novel addition is the integraHash binding—every token knows which Document Record it represents. Standard ERC interface, novel document binding.

MPC Architecture

Integra's MPC implementation follows the Lindell17 2-party ECDSA protocol:

1. Key Generation: Multiplicative-to-additive share conversion
2. Pre-signing: Paillier ciphertext computation for efficiency
3. Signing: Interactive protocol producing standard ECDSA signatures
4. Verification: Standard secp256k1—any Ethereum node accepts it

The resulting signatures are indistinguishable from single-key signatures. Full compatibility with every Ethereum application.

EAS Integration

Integra smart contracts query EAS directly for authorization:

function claimToken(bytes32 attestationUID) external {
    Attestation memory attestation = _eas.getAttestation(attestationUID);
    require(attestation.schema == CLAIM_SCHEMA, "Wrong schema");
    require(attestation.recipient == msg.sender, "Not recipient");
    // Transfer token to claimer
}

No proprietary identity system—standard EAS queries that work with any attester.
