Description
Overview
Sequence Wallet is a developer-first, non-custodial smart wallet infrastructure designed to unify crypto wallet experiences across entire ecosystems. It eliminates wallet fragmentation by giving every user a single address that works across all apps in a platform.
Key Features
- One Address Across Apps — Users get a single non-custodial wallet address that spans the entire ecosystem, eliminating scattered assets and fragmented liquidity.
- Sandboxed Smart Sessions — Each app's permissions are isolated in sandboxed sessions, meaning even if one app is compromised, the rest of the ecosystem stays secure.
- Zero-Config Authentication — Supports Google, Apple, email, and passkey sign-in with no seed phrases required, plus multi-factor recovery options.
- Enterprise-Grade Security — Signing keys are hardware-isolated in AWS Nitro Secure Enclaves (TEE), with public remote attestations audited by Quantstamp and CoinCover.
- Multi-Platform SDKs — Available for Web, React Native, Unity, and Unreal Engine, enabling rapid integration across any platform.
Use Cases
- Gaming Ecosystems — Onboard players across multiple titles with a shared wallet, gasless transactions, and seamless token portability.
- DeFi & Payments — Enable gas-sponsored onboarding, built-in swaps and onramps, 1-click cross-chain transactions, and real-time portfolio data.
- Chain Growth & DevRel — Attract developers and users with a branded wallet and developer hub hosted on your domain.
- Wallet & Infrastructure Teams — Deploy a complete wallet solution in minutes using the Wallet Development Kit (WDK) or Sequence Builder.
Highlights
Pros
- Single wallet address works across an entire ecosystem of apps, eliminating wallet fragmentation and scattered assets for users.
- Hardware-isolated signers in AWS Nitro Secure Enclaves (TEE) with public attestations audited by Quantstamp and CoinCover provide enterprise-grade security.
- Sandboxed Smart Sessions isolate permissions per app, so even if one app is compromised the rest of the ecosystem stays secure.
- Zero-config authentication via Google, Apple, email, and passkeys eliminates the need for seed phrase management while supporting multi-factor recovery.
- Multi-platform SDKs for Web, React Native, Unity, and Unreal Engine enable rapid wallet integration and gas sponsorship for frictionless onboarding.
Cons
- The Guard Key is owned by Horizon (the parent company) and the Torus Key is not user-controlled, partially undermining the full self-custody claim.
- Login delays via social/email can reach 20–30 seconds due to third-party authorization, creating a sluggish onboarding experience.
- Limited to EVM-compatible chains (Ethereum, Polygon, Arbitrum, Optimism, BSC, Avalanche, Gnosis), with no native support for non-EVM ecosystems like Bitcoin or Solana.
- WalletConnect interactions require QR code scanning, which is more cumbersome and time-consuming than browser extension wallets like MetaMask.
- Social/email login depends on a third-party Torus key, meaning the wallet can be compromised if the user's email or social account is breached.
