Best Sequence Alternatives [2025]

Sequence is a powerful developer platform offering open-source SDKs and a robust library of pre-built, extensible smart contracts. Its standout features include a Unity-verified embedded wallet, multisig smart wallets, AWS Nitro enclave security, and account abstraction support. Still, teams building advanced wallet experiences may benefit from exploring other options. Here are the top alternatives to Sequence in 2025:

1. Openfort (that's us 👋)

Openfort is a fully open-source wallet infrastructure stack and ecosystem SDK, built to enable developers to craft embedded, self-custodial wallets with full control over UX, authentication, and infra.

Why Openfort aligns with Sequence developers

  • Modular smart wallets: ERC-4337 + EIP‑7702, built-in session and auth workflows.
  • End-to-end open stack: MIT-licensed SDKs, UI, and backend—usable on any infrastructure.
  • Multiverse SDK support: React, React Native, Unity WebGL/Native, Telegram mini‑apps.
  • Auth flexibility: Integrate Auth0, Firebase, or custom OIDC flows.
