Hemi bridges the gap between the distinct worlds of Bitcoin and Ethereum like no other network. For Bitcoin users, it provides new opportunities to utilize your BTC effectively. For Ethereum users, Hemi delivers the scalability and performance expected from an L2, along with native access to Bitcoin’s security, data, and deep liquidity.

This wouldn’t be possible without the contributions of all the Day One participants in the Hemi ecosystem — those who share the vision of One Network, powered by Bitcoin and Ethereum.

Explore the wide range of possibilities available on Hemi from the very beginning.

For Users

Hemi integrates with leading decentralized exchanges (DEXs) to make token swaps seamless, secure, and efficient. DeFi on Hemi allows for the native integration of Bitcoin alongside the full gamut of EVM-supported tokens, creating new opportunities for Bitcoin holders to generate passive income via liquidity provision and yield farming. On day one, users can trade popular tokens like xBTC, yBTC, zBTC, and WETH across the following platforms:

Sushi – Trade on the Sushi DEX, featuring an automated market maker, yield farming, optimizations for efficiency with a dAPP interface, and community-driven governance.
iZumi – A multi-chain DeFi protocol providing One-Stop Liquidity as a Service (LaaS).
DODO – Trade on a DEX featuring a Proactive Market Maker (PMM) built to increase capital efficiency and reduce slippage. DODO also offers fair token launches with crowdpooling, and single-sided liquidity provision enabling users to farm with a single asset rather than a balanced pair. The PMM algorithm maintains the balance of the pool.
Atlas – Hemi’s native DEX provided by Algebra Finance that will implement a v4 architecture to enable hooks and additional yield-generating opportunities for liquidity providers.
Oku (Uniswap): A non-custodial meta-aggregator for EVM featuring access to advanced analytics and a dashboard from which traders may enter or exit positions via market or limit orders, manage various liquidity positions, and convert to and from fiat currencies via integrated onramps.
PassDEX: A multi-EVM chain DEX allowing users to swap, provide liquidity, and earn rewards built around rewards and community-driven governance to drive participation.

Maximize asset utility with Hemi’s integrated lending platforms. Lending on Hemi is uninhibited, empowering individuals holding crypto who may be underserved or sidelined by traditional institutions to borrow, lend, and grow their assets in a decentralized environment. These protocols allow you to lend tokens and earn interest, making your holdings work for you. Day One integrations include:

Layerbank – Access a scalable, secure, and efficient institutional-grade lending protocol, designed for larger liquidity providers and sophisticated users that facilitates high-volume lending and borrowing with competitive interest rates.

LendOS – With LendOS, find flexible borrowing and lending solutions, tailored for retail users. With its decentralized and transparent tools, LendOS offers liquidity or opportunities to earn interest beyond the scope of what is typically available in the traditional banking system.
ZeroLend – Explore a lending market for DeFi lending, liquid restaking token (LRT) lending, and real-world asset (RWA) lending on a fully audited, custody-free platform.
AJNA – Participate in peer-to-pool permissionless lending pools serving lenders and borrowers, functioning free of governance or price feeds.

Hemi also connects the gap between other networks, enabling effortless cross-chain transfers. Tunnels to Hemi are completely sovereign, and decentralized, without intermediaries or central providers. Tunneled assets serve as direct on-chain collateral, promoting trustless and secure interactions. Day One cross-chain solutions include:

Native Tunnels between Bitcoin/Hemi and Ethereum/Hemi

Hemi’s multi-asset staking platform is designed specifically to accommodate Bitcoin with a trust-minimized, secure approach that lets holders stake and earn without fear of slashing conditions. Hemi utilizes a fully audited staking reward smart contract, which is fine-tuned to allocate to depositors. These staked assets are not used to validate blocks, removing any slashing risks for participants.

Move assets in and out of the staking contract in minutes, subject to network confirmation times, without lengthy bonding or unbonding rounds, for equal access to staking rewards and liquidity as needed.

Compound your earnings with Hemi’s restaking solutions.

Cygnus– By integrating Cygnus, a platform offering efficient delegation and restaking services for liquid-staked assets, Hemi enables you to maximize returns with ease.
