This repository contains the predeploy contracts for the Sova Network.
The Sova Network enables smart contract to directly interact with the Bitcoin blockchain. This interaction is done through the use of custom precompiles and predeployed contracts. This feature set allows smart contract to do things like broadcast transactions, decode payloads, verify signatures, get block height and more!
The Sova precompiles provide built-in Bitcoin transaction validation, broadcast capabilities, and UTXO management with safeguards against double-spending and replay attacks. These features power the SovaBTC.sol predeploy contract and are available to any developer through the SovaBitcoin.sol library. Our goal is to make it as easy as possible to add native Bitcoin functionality to your Sova smart contracts.
