✍️ The BTCFi innovation on @Starknet is transforming Bitcoin from its singular role as "digital gold" into a highly productive core asset within the Web3 ecosystem. Through unique architecture and design, BTCFi not only drives real liquidity and network security but also introduces institutional funds and priority borrower strategies, enhancing the vitality and sustainability of the ecosystem. Core products include: Bitcoin staking, where users can directly stake BTC to earn annualized returns while contributing to network security; Institutional funds that bring in large-scale capital, enhancing liquidity and reducing risk; Leverage vaults that allow users to borrow and reinvest, amplifying returns; The money market builds a BTC-based lending ecosystem, enriching DeFi application scenarios. In terms of incentive programs, Starknet has invested 100 million $STRK to promote BTC pools, lending, and liquidity, incentivizing real productive activities and avoiding the pitfalls of past projects where incentives flowed to idle deposits. Early data shows that stakers and liquidity providers have already achieved double-digit annualized returns, with user participation rapidly increasing. The entry of institutional capital and priority borrower strategies ensures that the project is aimed at long-term development from the outset, promoting broader on-chain applications of BTC. In the future, BTC will no longer be merely a store of value but an asset with high financial productivity, deeply involved in lending, investing, and network security. As the BTCFi ecosystem matures, will Bitcoin's role in DeFi experience a qualitative leap, becoming a truly productive asset? This is not only about technology but also about the future direction of the entire crypto economy.
