Sequence Kit
Sequence is a modular crypto infrastructure stack that unifies wallets, 1-click cross-chain payments, and real-time data layers across EVM chains.
Overview
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 offers developers and ecosystems a suite of integrated tools including smart wallets, seamless cross-chain payments, and a real-time multi-chain data indexer. This unified stack addresses common challenges such as wallet fragmentation, complex cross-chain transactions, and unreliable data feeds by providing a single account system, 1-click crypto payments, and instant access to indexed blockchain data.
The platform’s smart wallets enable ecosystems to offer users a single account that works across multiple dapps and chains, improving user experience by simplifying account recovery and enhancing security through sandboxed sessions. Its payment infrastructure supports accepting any token from any wallet on any chain with a single click, enabling developers to build frictionless payment flows including swaps, funding, and earnings. The real-time indexer delivers near-instant multi-chain data such as balances, token prices, contract events, and webhooks, powering applications that require reliable and up-to-date blockchain information.
Sequence stands out by combining these capabilities into one modular stack, reducing integration complexity and operational overhead for developers. It supports a wide range of verticals including DeFi (swaps, vaults, lending), stablecoins (cross-chain transfers and settlements), gaming (gasless buys, token economies), and branded chain hubs. With over one million blockchain interactions powered and partnerships with notable projects like Ubisoft and Immutable, Sequence demonstrates strong adoption and real-world utility. Developers can get started quickly using the open SDKs and comprehensive documentation available on their website, with options to build directly on the platform or engage with the team for tailored roadmap support.
The Problem
Developers face fragmented wallet experiences, complex cross-chain payment flows, and unreliable real-time blockchain data, which hinder building seamless Web3 applications. Managing multiple accounts, handling token payments across chains, and integrating consistent data feeds remain significant challenges.
