ENGINEERING EXCELLENCE
Core Technical Capabilities
Our Bitcoin-to-Aptos bridge is built on a foundation of proven, secure, and performant engineering principles, designed to give your team a production-ready asset gateway.
03
Sub-Second Finality on Aptos
Once a Bitcoin transaction is confirmed, the wrapped asset is minted on Aptos in under one second, leveraging the network's parallel execution and BFT consensus for instant settlement.

Bitcoin-to-Aptos Bridge
Frequently Asked Questions
Get clear answers on the technical details, security, and process of building a custom Bitcoin-to-Aptos bridge with Chainscore Labs.
Our bridges use a secure, multi-signature custodian model. Bitcoin is locked in a Taproot/P2WSH address controlled by a decentralized set of validators. On the Aptos side, we deploy a custom Move module that mints a canonical wrapped asset (wBTC.a) upon verification of the lock transaction. We leverage Move's resource-oriented model for superior security and formal verification of the mint/burn logic. The bridge state is monitored 24/7 by our proprietary Chainscore Sentinel nodes.
