Sequence Wallet

One crypto wallet that works everywhere

Sequence Wallet is a non-custodial smart wallet infrastructure that gives users a single crypto wallet address across an entire ecosystem of apps. It features sandboxed smart sessions for per-app permission isolation, zero-config auth (Google, Apple, email, passkeys), and enterprise-grade security with hardware-isolated signers in AWS Nitro Secure Enclaves.

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.
