Sequence

Sequence was created to address some of the most persistent technical and user experience challenges in the Web3 development space. Traditional wallets and payment systems fragment user identities and create friction in the transaction process. Meanwhile, developers often face long integration times and unreliable or slow blockchain data. Sequence solves these issues with a unified platform designed from the ground up for scalability, interoperability, and ease of use.

The core offering is the Sequence Wallet—a smart contract wallet that enables users to maintain a single identity across multiple applications within an ecosystem. Unlike traditional wallets that generate a new address for every interaction, Sequence gives users one wallet that works everywhere. Developers can easily integrate this wallet into their apps using SDKs for Web, React Native, Unity, and Unreal, significantly reducing build time.

On top of the wallet layer, the platform offers Sequence Payments, a universal 1-click payment infrastructure. This tool lets users pay, fund, or earn using any token on any chain with just one click. It removes the need for manual bridging and token swapping by handling everything under the hood—enabling a truly seamless payment experience. Whether you’re building an NFT storefront, DeFi app, or gaming platform, Sequence’s Trails SDK makes payment flow integration a matter of minutes.

Another critical part of the stack is the Sequence Indexer, a real-time data service that supports every ERC20, ERC721, and ERC1155 token on all major EVM chains. It provides token balances, transaction history, price data, and smart contract events with sub-300ms response times. This allows developers to power responsive interfaces, analytics dashboards, and offchain workflows without needing to build a separate indexing service.

Competitors in this space include Alchemy, QuickNode, and Infura, all of which offer blockchain infrastructure services like RPC nodes and indexing. However, Sequence stands apart by providing a holistic stack that includes wallet, payments, and indexing—all tightly integrated and optimized for rapid development. Its focus on UX, developer speed, and production readiness makes it a go-to solution for projects that need to launch fast and scale efficiently.

Sequence provides numerous benefits and features that position it as a top-tier platform in the Web3 infrastructure ecosystem:

• Unified Smart Wallet: One non-custodial wallet address per user that spans across all apps in an ecosystem. No more wallet fragmentation or scattered assets.
• Smart Session Security: Apps run in sandboxed environments with isolated permissions. Keys are hardware-isolated and never co-located, offering strong guarantees of security.
• 1-Click Payments: Accept any token from any wallet on any chain. Sequence handles the swaps, bridges, and gas fees automatically.
• Developer-Friendly SDKs: SDKs available for Web, React Native, Unity, and Unreal. Integrate payments, wallets, and data in minutes.
• Real-Time Indexer: Fast, multi-chain data with sub-300ms response times. Get balances, prices, metadata, and event logs from any EVM chain.
• Chain-Agnostic Support: Works across Ethereum, Arbitrum, Polygon, Avalanche, Optimism, Gnosis, and Base (Coinbase) with native integration.
• Custom Wallet Branding: Launch your own branded wallet instance or self-host using the Wallet Development Kit.
• Gas Sponsorship Options: Developers can sponsor gas fees with customizable rulesets to onboard users frictionlessly.
