# Background Bitcoin serves as an if not the most important cornerstone of crypto, yet native BTC from the Bitcoin chain lacks smart contract functionality, limiting its liquidity and integration with DeFi protocols. The lack of robust liquidity is the primary obstacle preventing BTC assets from realizing their full potential within EVM chains and other ecosystems. This limitation effectively freezes a vast reservoir of dormant liquidity within the BTC ecosystem, restricting its value to flow to other ecosystems and preventing it from playing a more active role in the broader DeFi landscape. At StakeStone, we believe a strong BTC asset in the EVM ecosystems should have the following key features, and have built SBTC and STONEBTC with the following features in mind: 1. Liquidity 2. Use cases STONEBTC and SBTC together represent a comprehensive solution for enhancing the liquidity, utility, and yield potential of BTC assets within the EVM ecosystems and other chains. By addressing this liquidity challenge, StakeStone's BTC assets aim to significantly expand BTC assets' use cases in the crypto ecosystem, providing our users with liquidity and yield. StakeStone's innovative BTC assets empower users to fully unlock the potential of their BTC holdings, providing unmatched liquidity and efficiency in the ever-evolving world of crypto. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
