DUAL-PATH VERIFICATION

Add Taifoon as a trustless verification layer alongside your existing security stack. Your validators + our proofs = mathematical finality.

INTEGRATE PROOFS →Dev Channel

HOW IT WORKS

Three steps to integration

Message Sent

Source chain emits a cross-chain message. Your existing validator set processes it normally.

Taifoon Proof in Parallel

Simultaneously, Taifoon generates an MMR inclusion proof for the source event. No added latency to your flow.

Dual Verification

Destination verifies both: your validators AND Taifoon's cryptographic proof. Mathematical finality, zero bridge trust.
