Onchain Bridges Documentation

Interoperability and compliance infrastructure for tokenized real-world assets (RWAs). A single token, the same KYC posture, on every chain a regulated investor wants to use, built on Chainlink (CCIP, the Cross-Chain Token standard, the Automated Compliance Engine, the Runtime Environment, and Proof of Reserve). Live testnet dApp: https://rwa-testnet.onchainbridges.com

Protocol documentation

1. Overview, what the protocol does and who it is for
2. Architecture, system layers and components
3. Compliance Model, KYC enforced at every transfer via Chainlink ACE
4. Cross-Chain Routing, how tokens move across chains (CCIP + CRE)
5. Integration Guide, onboarding chains, issuers, and dApps
6. Contract Reference, live testnet addresses across supported chains
7. Security Model, threat model, key custody, upgrade paths

Security audit

• Security Review, independent source-based audit (Foundry forge-lint + Cyfrin Aderyn + solhint + cargo-audit): 0 Critical/High/Medium across all live networks (EVM + Solana + Stellar).
• Verification and Audit Ledger, every contract, every chain, with block-explorer links.

Networks

The protocol is deployed natively across multiple public testnets. Full per-chain contract addresses are in the Contract Reference; the multi-chain design is in Architecture.

• EVM testnets: Ethereum (Sepolia), Polygon (Amoy), Soneium (Minato), Plume, Sonic, Astar (Shibuya)
• Non-EVM: Solana (Devnet), Stellar / Soroban
• In progress: Stacks (Bitcoin L2), bridge working, integration ongoing

Compliance (allowlist + pause enforced on every transfer) and the cross-chain bridge are implemented natively on each chain, EVM and non-EVM alike.

Status: pre-mainnet. Deployed and live on public testnets; a formal audit precedes mainnet.
