# iRWA Token Bridge (AI Token Bridge)

The AI Token Bridge uses AI to read any real estate security token regardless of its original standard and wraps it into iRWA (Integra Real-World Asset): a universal ERC-20 format that can trade on the Global Orderbook, participate in DeFi, and move across chains via IBC.

The bridge has four components:

* Standard Classifier: identifies the token’s original standard via ERC-165 supportsInterface() calls deterministic bytecode pattern-matching, not ML. The genuine AI component is the compliance normalization layer: reading transfer restrictions, eligibility rules, and jurisdiction mappings from heterogeneous schemas and normalizing them into a unified policy object for the compliance engine.
* Lock Vault: securely holds the original token during the wrapping process
* iRWA Factory: mints the iRWA wrapper
* Compliance Sync Oracle:  keeps compliance rules (transfer restrictions, eligibility, jurisdiction) synchronized between the original token and the iRWA wrapper. Propagates updates within one block finality (≤6 seconds). Trust model: initial deployment uses a permissioned oracle operated by Integra; decentralization path via Chainlink CCIP in Phase 2 roadmap.

**How compliance survives wrapping**

ERC-3643 and ERC-1400 tokens carry transfer restrictions and investor eligibility rules at the token contract level. The WrapperFactory preserves these restrictions via compliance hooks in the iRWA contract the wrapped token inherits the source token's restriction schema, which the oracle layer continuously synchronizes. An iRWA token representing a Reg D asset cannot be transferred to an unaccredited investor, even after wrapping. Compliance follows the token, not the platform. WrapperFactory.sol is deployed on testnet contract address available at docs.integralayer.com.
