WorldBridge

Bridge World ID verification to unsupported EVM chains using Chainlink CRE.

DeFi & Tokenization World Tenderly Thirdweb

What it is

WorldBridge is a World ID attestation gateway for EVM chains that do not natively support World ID verification. A user verifies once with World ID in the frontend, then a Chainlink CRE workflow validates that proof offchain and writes a signed attestation onchain via receiver contracts. Apps can later read a simple onchain verification status instead of re-running full proof verification each time. This solves the integration gap for unsupported chains, reduces repeated verification complexity, and provides a reusable human-verification primitive for minting, claims, voting, and other gated actions.

How it Works

  • Next.js + React frontend (/simulate) for wallet connect, World ID capture, simulation flow, and onchain readback.
  • Chainlink CRE workflow in cre-workflows/worldid-workflow for proof verification and report generation.
  • CRE EVMClient.writeReport() to broadcast signed reports to receiver contracts.
  • Upgradeable Solidity contracts (WorldIdReceiver, WorldIdReceiverImpl) as store + receiver path.
  • Tenderly virtual testnets for Avalanche Fuji and ApeChain Curtis deployment lanes.
