Bitlayer is a pioneering <a href="https://www.toolsforbitcoin.com/tag/layer%202" target="_blank">Layer 2</a> solution designed to enhance Bitcoin's scalability and programmability while maintaining its foundational security and decentralization. By implementing the BitVM paradigm, Bitlayer introduces Turing-complete smart contract capabilities to the Bitcoin network, enabling developers to build complex decentralized applications (dApps) directly on Bitcoin. This integration allows for seamless migration of Ethereum-based applications to Bitlayer without significant modifications.

Hermetica is a decentralized finance (DeFi) platform that introduces USDh, the first Bitcoin-backed, yield-bearing synthetic dollar. USDh allows users to hold a stable, liquid dollar asset fully backed by Bitcoin, providing an alternative to traditional fiat-backed stablecoins. By staking USDh, users can earn yields of up to 25% APY, derived from perpetual futures funding payments.

Echo Protocol is a Bitcoin-native staking and liquidity layer, enabling users to bridge, stake, and earn yield on their BTC without leaving the Bitcoin ecosystem. With over $260 million in total value locked (TVL) and more than 3,000 BTC staked, Echo is positioning itself as the foundational infrastructure layer for Bitcoin DeFi, unifying liquidity and composability across multiple chains and platforms.

Arkadiko is a decentralized, non-custodial liquidity protocol built on the Stacks blockchain, aiming to bring DeFi capabilities to Bitcoin. It allows users to collateralize assets like STX tokens to mint USDA, a stablecoin soft-pegged to the US Dollar, enabling increased liquidity while maintaining original asset exposure.

Badger is a decentralized finance (DeFi) platform focused on enabling users to earn yield on their Bitcoin holdings by providing liquidity across various DeFi protocols. With an emphasis on simplicity and security, Badger allows Bitcoin holders to maximize returns through automated yield farming, staking, and other yield-generating strategies.
