Sequence Embedded Wallet SDK & Ecosystem Wallet

Sequence Embedded Wallet Infrastructure

Sequence provides a comprehensive Wallet-as-a-Service platform for application developers and ecosystem operators who need to embed crypto wallet functionality without managing keys, building auth flows, or handling gas sponsorship.

Embedded Wallet SDK (Developer)

The Sequence Developer Wallet is the embedded wallet SDK for individual application developers shipping crypto wallet functionality at scale.

Key capabilities:

• Frontend SDKs – Web, React Native, Unity, and Unreal SDKs with customizable UI components
• Zero-Config Auth – Non-custodial sign-in via Google, Apple, email, and passkeys with no custom auth setup required
• Backend SDKs – Programmatic mints, burns, transfers, batching, and contract monitoring
• Sequence Sidekick – Dockerized, ready-to-deploy crypto backend with integrated key management
• Gas sponsorship – Customizable gasless transaction rulesets enabling friction-free user onboarding
• Smart sessions – Per-app permission isolation protecting users from malicious contracts
• Enterprise-grade security – Hardware-isolated signers in AWS Nitro Enclaves with public attestations by Quantstamp and CoinCover

Ecosystem Wallet (Platform Operators)

The Sequence Ecosystem Wallet extends wallet infrastructure to chain operators, game publishers, and cross-app platforms, providing a single account address spanning an entire app ecosystem.

Key capabilities:

• Single address across all ecosystem apps – One wallet address per user works across every integrated application, eliminating wallet fragmentation
• Sandboxed Smart Sessions – Per-app permission boundaries prevent cross-app asset access
• Branded wallet on your domain – Fully branded wallet experience deployable via the Wallet Development Kit (WDK)
• Immersive app discovery – Users discover ecosystem apps directly within the branded wallet interface
• Predictable pricing – Unlimited wallets at all tiers with no per-active-wallet fees

Both products are built on the same non-custodial infrastructure and trusted by Arbitrum, Avalanche, Base, BNB Smart Chain, Ethereum, Gnosis, Optimism, and Polygon ecosystems.
