AutoLock DeFi

AutoLock DeFi is a Real World Asset (RWA) tokenization protocol that converts vehicle ownership data into blockchain assets.
In Brazil, millions of vehicles represent locked capital that cannot easily be used in decentralized finance. AutoLock DeFi unlocks this value by tokenizing vehicles as ERC-721 NFTs.
The system verifies the vehicle through oracle-verified data and verifies the user through World ID before minting the asset on-chain.
A Chainlink CRE workflow orchestrates the verification pipeline. The workflow fetches vehicle registry data and valuation information from external APIs, reaches consensus through the oracle network, and sends the verified report to smart contracts that mint the vehicle NFT.
This approach demonstrates how decentralized oracle workflows can securely tokenize real-world assets and bridge physical collateral with DeFi liquidity.

AutoLock DeFi is built using a modular architecture that combines decentralized oracle workflows with smart contract settlement.

The frontend is built with Next.js and integrates wallet connectivity using Thirdweb and identity verification using World ID.

A backend worker triggers a Chainlink CRE workflow responsible for orchestrating the verification process.

The CRE workflow performs several steps:
• verifies the user using World ID
• fetches vehicle registry data from external APIs
• retrieves market valuation data
• reaches consensus through the Chainlink DON

Once verified, the workflow sends a report to the on-chain settlement layer.

The smart contract layer consists of three contracts:
• Forwarder
• VehicleTokenConsumer
• VehicleNFT (ERC-721)

The consumer contract receives the oracle report and mints the NFT representing the vehicle.

The entire system runs on Tenderly Virtual Testnet, which provides deterministic blockchain infrastructure and transaction debugging.

This process also helped validate how CRE can be used as a powerful orchestration layer for real-world asset tokenization workflows.
