Smart Contracts Architecture

Secure & Transparent Smart Contracts

Explore the blockchain-based contracts powering AlgoKYC. Audited, transparent, and designed for maximum security.

Core Contracts

Three main smart contracts work together to provide secure KYC verification

Verification Contract

Manages the KYC verification process and stores verification proofs on-chain.

Zero-knowledge proofs
Immutable records
Batch verification

Identity Registry

Maintains a registry of verified identities with privacy-preserving commitments.

Merkle trees
Privacy hashing
Revocation support

Access Control

Manages permissions and controls who can verify and access identity data.

Role-based access
Multi-sig support
Time-locked operations

Contract Interaction Flow

How the contracts work together to verify identity

2

Proof Verification

Verification contract validates the ZK proof without revealing data

3

Registry Update

Identity registry records the verified commitment on-chain

4

Access Grant

Access control contract grants permissions to verified users
