This flexibility allows developers and studios to incorporate Sequence Smart WaaS directly within their apps, combining it seamlessly with any game’s existing UI to maintain brand consistency and familiar gameplay aesthetics. But that’s not all. For developers and studios aiming to prioritize rapid, smooth onboarding, Sequence Embedded Wallets offer the perfect solution.

Sequence Embedded Wallets: The tech under the hood

Sequence Smart WaaS is built on a novel combined architecture of smart wallet technology and a secure enclave signing service.

Sequence Smart WaaS is built on a novel combined architecture of smart wallet technology and a secure enclave signing service. By design our solution is fully equipped with OpenID Connect and OAuth2 support, designed in a non-custodial framework, making it simple to connect any OAuth2 provider for seamless wallet access. Developers can bring in their own authentication system for full oversight to manage player profiles — and integrate with Google, Apple, or any OAuth provider right out of the box. Sequence Smart WaaS sets a new standard for onboarding processes, unmatched by competitors. With support for secp256k1 and secp256r1, our web version ensures that session keys are stored securely in an enclave, making them completely tamper-proof. Wallet keys are safeguarded by a cutting-edge secure enclave signing service, utilizing multi-factor multisig technology powered by Sequence smart wallets. This service is not only novel but also fully open source and verifiable. Additionally, Sequence Smart WaaS prioritizes user recovery, providing straightforward options for account retrieval. In the unlikely event of authentication provider issues, users can effortlessly regain access to their wallets by exporting their recovery key. Designed with best-in-class flexibility and security, Sequence Smart WaaS is compatible with popular libraries like ethers.js and Viem, ensuring a frictionless integration tailor-made for developers. We champion open ecosystems, avoid vendor lock-ins, and support seamless interoperability with Metamask, Wallet Connect, and any web3 wallet you choose to bring to your project. This approach guarantees an optimal experience across both web2 and web3 ecosystems, from day one and beyond. We focus on future-proofing technology so you can focus on building great games that players will love.
