Bạn sẽ kiến tạo, triển khai hạ tầng DeFi hiện đại trong lĩnh vực stablecoin, staking, thanh khoản, cross-chain với tiêu chuẩn bảo mật cao, đồng thời dẫn dắt phát triển các sản phẩm tài chính phi tập trung toàn cầu.

Who We Are:

Ethena Labs is at the forefront of the next wave of DeFi, dedicated to building products for modern finance. Ethena is a synthetic dollar protocol built on Ethereum that provides a crypto-native solution for money, USDe, alongside a globally accessible dollar savings asset, sUSDe.

Our core mission is to provide truly crypto-native financial solutions that are globally accessible and bridge the gap between TradFi and the digital asset economy. We believe in transparency, efficiency, and empowering both individuals and institutions with greater control over their assets.

What we are Doing:

Ethena Labs is actively building and deploying a suite of groundbreaking products designed to address key challenges and unlock new opportunities within the digital finance landscape.

Our flagship product, USDe, is a synthetic dollar backed by digital assets, and takes the novel approach of using a delta-neutral hedging strategy to maintain its peg. This provides a truly scalable and censorship-resistant digital dollar.

Building upon USDe, we offer sUSDe. sUSDe provides crypto-native rewards generated from funding rates in derivatives markets, offering an alternative to existing products tethered to the traditional financial system.

Furthermore, we are actively developing solutions to facilitate institutional adoption of digital assets. In partnership with Securitize and Blackrocks BUIDL fund, USDtb provides a more traditional, asset-backed stablecoin option, leveraging established financial infrastructure to appeal to institutional clients. Expanding on this, iUSDe is designed specifically for traditional financial institutions, incorporating necessary compliance features to enable them to access the crypto-native rewards our protocol generates, in an institutional-friendly manner.

Finally, our most ambitious undertaking to date is Converge, our joint blockchain initiative with Securitize. This hybrid blockchain is designed to be the nexus where DeFi meets the needs of CeFi and TradFi. Converge aims to be a primary issuance layer for tokenised assets, integrating seamlessly with existing DeFi protocols to provide institutions with an environment to participate in the decentralised economy.

Through these offerings, Ethena Labs is not just creating new financial products; we are building the foundational infrastructure for a more open, efficient, and interconnected global financial system.
