Chain-Key Tech

chainkey.tech introduces a new kind of bridging technology that moves beyond traditional intent or message passing. Send ICP and BTC to any chain with a single transaction.⊕ Coming Soon

The Bridge Problem

Today's most popular bridge aggregators can't move BTC directly to chains like BASE, SOL, or ARB. ICP remains even more isolated - a technological island in the vast crypto ocean.

Action Driven Addresses

Current bridges force users to either sign multiple transactions or grant extended wallet access - both poor solutions for security and usability. We've reimagined this entirely: send your assets to a single address that knows exactly what to do with them. Actions include trading, borrowing, lending, or any other DeFi operation

Each address is composed of three elements:

Chain A Base Address
+ Chain B Destination Address
+ Intent
--------------------------------------
Chain A Derived Action Driven Address

Behind the scenes, we handle all complexity using threshold ECDSA or EdDSA signatures, powered by:

• On-chain validation - all verification happens directly on ICP, with no external dependencies or trust requirements
• Native oracles - ICP's direct web integration eliminates the need for third-party oracle networks
