Senior Frontend Engineer 前端开发工程师

Mantle is building the largest sustainable hub for financial and consumer on-chain applications. Conceived by a community of builders as a burgeoning on-chain ecosystem pioneering a vision for the mass adoption of token-governed technologies, Mantle Ecosystem comprises an Ethereum layer 2 (L2) — Mantle Network, a decentralized autonomous organization (DAO) — Mantle Governance, one of the largest on-chain treasuries — Mantle Treasury, and an Ether (ETH) liquid staking and restaking protocol — mETH Protocol: all built on Ethereum. To support the next-generation of innovators, builders, and developers, Mantle is growing its ecosystem via Mantle EcoFund, a catalyzed capital pool of $200M. Mantle’s Showcase Apps program lends additional support and publicity to ecosystem projects in categories such as real world assets (RWA), web3 gaming and intent-driven applications.
