LayerEdge Partners with Sygma to Develop The First Trust-Minimized MPC-Based Bridge for Bitcoin & In

LayerEdge is partnering with Sygma to develop the first trust-minimized multi-party computation (MPC) based Bridge for Bitcoin & Inscriptions, to power the future of BTCFi.


LayerEdge offers a programmable infrastructure that leverages Bitcoin’s native security to enable BTCFi for native assets and inscriptions, fostering a utility-driven ecosystem. LayerEdge is positioned as the first Optimistic Rollup on Bitcoin, powered by its Hybrid Modular DA, which provides data verification and validation natively on Bitcoin. This Hybrid Modular DA also lets other Bitcoin L2s use Bitcoin for data verification and validation while storing data on any existing DA layer. Read more here.

Sygma is a cross-consensus interoperability protocol, enabling general message passing, asset transfers, non-fungible tokens, and decentralized finance. Sygma has been incubated by ChainSafe, a leading blockchain research and development firm specializing in infrastructure solutions for the decentralized web and evolved from the humble beginnings of ChainBridge. It provides native interoperability between the Ethereum, Bitcoin and Polkadot ecosystems. It has securely bridged over $70m in volume and holds over $120m in total value locked

Building the First Trust-Minimized Bridge

With this strategic collaboration, LayerEdge and Sygma is set to develop first trust-minimized multi-party computation (MPC) based Bridge for Bitcoin. This bridge will power users to seamlessly transfer their BTC & inscriptions between the Bitcoin network and LayerEdge.

The bridge employs a federated multi-party computation (MPC) approach to manage the key for validating bridging requests, ensuring no single entity controls the critical signing key. The key is generated through a secure ceremony involving multiple relayer agents, with the key never fully assembled in one place, preventing single points of failure and vulnerabilities.

Instead of relying on multi-sig or other traditional methods, these relayers participate in the MPC ceremony for each bridging event, enabling distributed computation on secret inputs without revealing outputs. This approach provides a secure foundation for cross-chain transactions and data transfers. These Relayer agents include ChainSafe, Beware, Phala, Blockops, Sygma, & LayerEdge Foundation.


The Sygma Protocol’s foundation, Chainbridge, was also the chosen bridge behind the launch of Avalanche’s official Avalanche — Ethereum bridge, bringing together unparalleled expertise and innovation to deliver a state-of-the-art bridge solution. This collaboration marks a significant step forward in our mission to enhance the security and efficiency of cross-chain transactions for Bitcoin ecosystem.

To mark this milestone and provide a strong commitment towards leading secure infrastructure for Bitcoin, we’re opening up an NFT badge for the community to claim and be part of the Orange Gang — claim it here.
