Asigna is a native multisig solution tailored for Bitcoin and Stacks made specifically to offer an extra layer of security to trusted wallets on both ecosystems. By implementing a native approach, we address two fundamental concerns: eliminating potential risks associated with smart contract strategies (specifically in the context of Stacks), and optimizing gas fees.
Our approach mirrors Bitcoin's native use of Taproot multisig transactions, widely regarded as the most gas-efficient solution. Similarly for Stacks, we've discovered through rigorous testing and comparison that native transactions prove far more cost-effective than other smart contract methods. Also we've gained the ability to link multisigs on both Stacks and Bitcoin using the sBTC approach, details of which can be found here: https://www.stacks.co/sbtc-deck.
Native strategies offer a pathway for extensive flexibility as they enable all the operations a standard wallet can usually perform. This includes interactions with Decentralized Exchanges (DEXes), bridges, a myriad of Dapps on Stacks, NFT marketplaces, Ordinals, and BRC20 among others.
In addition, we ensure the security of your assets by not interacting with users' private keys, dealing solely with signatures from widely-used wallets. Also, even in the unlikely event of Asigna protocol discontinuing, both Stacks and Bitcoin wallets can be restored - that's the resilience and strength of our native approach.
