TAIFOONDeFi Protocols
Every proof follows the same 5-level path. Your protocol contract only needs to verify against L5 (SuperRoot) — all lower levels are proven automatically.
A user deposits ETH as collateral on Ethereum. Your lending market on Base wants to extend credit. Instead of using an oracle or relayer, your contract calls verifyInclusion() against the on-chain SuperRoot — confirming the deposit event with cryptographic certainty.
No trusted relayer. No validator committee. Your Solidity contract directly verifies the proof against the committed SuperRoot — which is updated on-chain every block.
Multi-hop routes (A → B → C) can be reconstructed into a verifiable ledger. A DEX aggregator attaches an inclusion proof per hop — creating an end-to-end cryptographic audit trail.
| Component | What You Get | Integration Effort |
|---|---|---|
| TaifoonUniversalVerifier | Solidity contract validating SuperRoot proofs — deploy once, works for all chains | ~20 lines |
| V5 Proof API | REST endpoint: generate proof for any tx/event on any supported chain | Standard HTTP |
| Sync Subscription | Webhook delivery — proofs auto-generated for your contract events | Webhook only |
| Event Filter | Filter by source chain, contract address, event signature (topic0) | Config only |
1. Deploy or reference TaifoonUniversalVerifier on your destination chain
2. Create a Sync subscription specifying source chain + event signature
3. Implement webhook handler to receive proof payloads
4. Call verifyAndExecute(proof) with the delivered V5 proof
5. Execute protocol logic (mint, release, liquidate) after verification passes
Custom Bridge: 6–12 months development, security audit, validator management, per-chain maintenance.
Taifoon Protocol Verification Integration: Days to integrate, battle-tested verifier, 41 chains immediately, one proof format forever.
A multi-chain lending protocol integrated Taifoon to verify collateral deposits across Ethereum, Arbitrum, and Base without deploying custom oracle infrastructure. By verifying MMR proofs on-chain, the protocol eliminated trust assumptions and reduced cross-chain collateral verification latency to under 30 seconds—securing over $2B in loans with cryptographic finality.
