Taifoon V5 MMR Proof Coverage
Every Across Protocol transaction indexed by the Taifoon universal scanner automatically receives a V5 MMR block header proof. The 5-layer proof chain attests:
01Transaction included in a specific block on source chain
02Block committed to the chain's Merkle Mountain Range (MMR)
03Chain MMR anchored in Taifoon's aggregated SuperRoot
04SuperRoot verifiable on-chain via TaifoonUniversalVerifier
Integration Checklist
01
Deploy Verifier
Reference TaifoonUniversalVerifier on your destination chain — one contract, all chains.
02
Create Subscription
Specify your source chain, contract address, and event signature.
03
Receive Proofs
Webhook delivers V5 MMR proofs on every matching event in real time.
04
Execute On-Chain
Call verifyAndExecute() — proof validates against the on-chain SuperRoot.
