Supernova Bitcoin Account Abstraction (AA)

Supernova is the first EVM extension-chain of Zenon and a hub for upcoming DeFi innovation where Solidity developers can directly participate in the Network of Momentum’s ecosystem using familiar tools and resources. Supernova is run by a subset of Pillars and is closely aligned with all the principles of the Network of Momentum, including Bitcoin support and use-cases.

The Bitcoin Account Abstraction (AA) layer of the Supernova extension-chain allows users to leverage their existing Bitcoin keys to sign transactions via smart wallets deployed as Solidity smart contracts.

It is designed to provide full compatibility with popular Bitcoin wallets like Xverse, which allows users to hold, swap and send Ordinals and Runes. This enables new DeFi use-cases on Supernova by tapping into well-established Bitcoin communities.

For developers, this solution opens up new opportunities to create innovative applications that leverage the strengths of Bitcoin and the use-cases provided by the EVM. It also helps attract a larger user base to Supernova by offering a familiar and convenient way to interact with it.

The implementation adheres to EIP-4337 specification.

Bitcoin support for both ECDSA and Schnorr. More info about popular Bitcoin addresses types here.
