Network Configuration

NEUS operates on a hub-and-spoke architecture with verification processing centralized on Base Sepolia and optional cross-chain proof storage on multiple testnet networks.

Hub Chain - Base Sepolia (Chain ID: 84532)

All verification processing occurs on the hub chain:

Contract ABIs

Complete contract ABIs are available in the open-source repository:

Source Code

All smart contract source code is available under Business Source License 1.1:

Note: Core contracts are under BSL 1.1; the testnet NEUSToken is MIT-licensed.

Verification Status

All deployed contracts have been verified on their respective blockchain explorers. Source code matches the deployed bytecode and can be independently verified.

Network Status

Current deployment status: Hybrid mainnet/testnet phase

Production Components

  • Asset Verification: Uses mainnet blockchain data for all verifiers

Development Components

  • Hub Processing: Base Sepolia (84532) - testnet for verification processing

  • Cross-chain Propagation: Operational across all spoke testnets

  • Protocol Infrastructure: Testnet contracts for development and testing

Mainnet Migration

Protocol infrastructure (VerifierRegistry, VoucherHub, Token) will migrate to mainnet following successful testing, audits, and community validation.
