WHY YOU CAN TRUST THE ARRIVAL

One transfer, six steps up to one root.

Your transfer is a cell on the tape. Seventeen sibling hashes carry it up to the root anchored on Taifoon mainnet. Anyone can redo the climb.

Reading the last transfer's proof.

INCLUDED
Steps 1 to 4 reach the chain root.
FINAL
Past the chain’s reorg depth.
ANCHORED
The root is on Base.

Submissions into the root

How often each chain and each protocol submits into its twig roots under the superroot, and what has reached the target chains. Counts are measured in spinner; a row is live when its last submission is within 3 block times, quiet when it lags, silent when nothing arrived in the window. Measured 1h ago.

Six layers, one root

A proof is a path. The block is hashed into its chain’s root, the chain’s root into the one root over every chain, and the block is final on its own chain. This is one proof, read live; each tick is one sibling hash it folds with.

Prove what your protocol depends on, with one API

Bridges, intents, solvers, oracles and agents all rest on the same facts: this block happened, this transaction is in it, this event was emitted. The coordination layer proves them on 60+ chains through one API, and anyone can check the proof without trusting Taifoon.

Check it yourself

The proof explorer above does exactly this in your browser: it recomputes the proof with keccak and compares it with the published root. The same construction runs in Rust and in Solidity, where checking a batch of blocks costs about 18k gas.

Fold 1
Hash your block with its siblings, level by level. The result must equal the chain’s root.
Fold 2
Hash the chain’s leaf with its siblings. The result must equal the published root.

Onboard your protocol

Get a proof of one of your own transactions, verify it, then register your contracts and events so the layer decodes and tracks your orders. Registration has a dry run that tells you, per chain, what is proven for you.

TWIGS · LIVE

Browse the most recent MMR twig per chain.

Every block header lands in a twig. Each {chain, block, twig_index} maps to a Merkle path to that chain's own root, then into the one root over every chain. These are the live tips, sampled from the busiest chains right now.

Idle. No twigs sampled yet.
