What the rules ask for on the token side, why the number is harder to pin down than it looks, and what changes when it comes with a proof.Read post →
·7 min readHow Three Bridges Accepted Forged ProofsA bridge releases money on one chain because something happened on another, and a verifier in the middle decides whether the claim is true. Nomad, BNB Chain's Token Hub, and Hyperbridge each made that verifier check a Merkle proof, and each accepted a forged one, about $750M between them. Where each check stopped short, and what a verifier has to be anchored to.

The attacker got Ethereum to release the funds against a burn on Unichain that never happened. Nobody stole a key. The verifier asked an RPC node what happened, and the node lied. Here's how it worked, and what changes when a verifier checks a proof instead of a report.
·4 min readWillow's State, Verified on EthereumWillow runs as its own chain, and its entire state is a single hash its validators sign into every block. A contract on Ethereum mainnet verified a proof of that consensus, stored the root, and checked a record from Willow's state against it. Ethereum contracts can now act on anything Willow indexes or stores, with no oracle in between.
·5 min readA Base Index, Verified on EthereumA contract on Ethereum mainnet verified that a sequence of consecutive Base blocks had been indexed completely and correctly, and that the sequence was a real, finalized stretch of Base itself. Ethereum contracts can now execute on indexes of Base events without a trusted oracle or relayer.

We proved the whole set of pool events behind it, every Swap and ModifyLiquidity across eight mainnet blocks with none missing, and a contract on Ethereum verified it for a few cents.

This week an Ethereum mainnet contract verified the same figure without a vote - the exact registered validator set and its consensus-layer balance, at a single finalized slot, in one transaction.
·4 min readAn Ethereum Index, Verified on EthereumWe deployed a contract to Ethereum mainnet that checked a Willow completeness proof — confirmation, on-chain, that a window of blocks was indexed with nothing left out, anchored to the real canonical chain. Here's how it works and what it unlocks.
