序列

Sequence is a comprehensive modular infrastructure platform designed to simplify and unify key components of Web3 development across Ethereum Virtual Machine (EVM) compatible chains. It provides developers and ecosystems with smart wallets, seamless 1-click cross-chain payment solutions, and real-time multi-chain data indexing. This unified stack enables building scalable, user-friendly blockchain applications with reduced friction in wallet management, payments, and data access.

At its core, Sequence offers smart wallets that consolidate user accounts across multiple chains and applications, eliminating wallet fragmentation and enabling secure sandboxed sessions. Developers can integrate social and email authentication, passkeys, and time-lock recovery mechanisms to improve user onboarding and account security. The Payments SDK supports universal 1-click crypto transactions, allowing users to pay or swap tokens across chains from any wallet, simplifying complex cross-chain interactions.

The real-time Indexer API delivers near-instant multi-chain data such as token balances, contract events, and price feeds, with webhook support for reactive applications. Sequence supports a broad range of SDKs and APIs including Web (React, Next.js, Vue), Mobile (React Native), Unity, Unreal, Go, and Node.js, enabling integration into diverse development environments. Its modular design allows teams to adopt individual components or the full stack depending on their needs.

Sequence is actively used in production by millions of users and integrated with leading blockchain ecosystems, gaming platforms, DeFi protocols, and NFT marketplaces. Developers can get started quickly using boilerplates and starter projects available in the documentation. The platform also offers hosted storefronts for NFT primary sales and ecosystem wallet launches. Comprehensive docs, community support via Discord, and a public GitHub repository facilitate onboarding and customization.
