Description

About us Bitget Wallet is the non-custodial crypto wallet designed to make crypto simple and secure for everyone. With over 80 million users, we bring together a full suite of crypto services, including swaps, market insights, staking, rewards, DApp exploration, and payment solutions. Supporting 130+ blockchains and millions of tokens, Bitget Wallet enables seamless multi-chain trading across hundreds of DEXs and cross-chain bridges. Backed by a $300+ million user protection fund, it ensures the highest level of security for users' assets. What you'll do Backend: Build on-chain service middleware, such as transaction processing, account management, on-chain data indexing, risk control, etc. Frontend: Responsible for DApp web interface development, implementing user features such as on-chain asset management and trading interactions. App: Develop multi-chain mobile wallet applications, supporting capabilities like account management, transactions, and push notifications. Smart Contract: Design and develop smart contracts in Solidity / Move / Rust, covering core logic such as authorization, swap, and payment, ensuring contract security and upgradability. Support mainstream blockchain ecosystems (such as Ethereum, Solana, Polygon, BSC, etc.) Drive the implementation of multi-chain wallets in key scenarios such as on-chain trading, asset security, and gas optimization Collaborate with teams including Product, Design, Security, and On-chain Infrastructure to continuously iterat
