How Does Sequence Compare to Competitors?

vs Argent

Sequence is targeting gaming ecosystems and platforms that will allow for unlimited wallets and branded UX across many apps, while Argent is targeting the individual mobile first smart wallet users. Sequence has a much higher degree of cross-app session isolation then Safe does however it requires an agreement from each ecosystem to participate.

Sequence is best suited for unifying multiple apps across a platform, while Argent is best suited for individual power users.

vs Safe (Gnosis Safe)

Safe has a larger multi-sig security market share for DAOs and teams, while Sequence offers a seamless consumer experience with social onboarding and gaming SDKs. Safe has more widespread DeFi adoption however it doesn’t have the capability to unify a single wallet across all apps.

Safe is best suited for institutional multi-sig uses, while Sequence is best suited for consumer based ecosystem development.

vs Biconomy

Both offer account abstraction however Sequence focuses on providing single addresses and Smart Sessions across the entire ecosystem while Biconomy focuses on providing SDKs and relayer services for developers. Sequence has a greater gaming heritage and branded wallet abilities.

Branded Ecosystem Hub (for a particular ecosystem) vs App Specific AA (for an app).

vs Dynamic

Dynamic offers social login wallets that are similar to what Sequence offers however Dynamic lacks the ability to provide ecosystem wide unification of multiple apps as well as the Smart Session security model that Sequence has available. Sequence has a better view of a user’s cross-chain portfolios and also has more robust developer hub features for chain teams.

Comprehensive Ecosystem Infrastructure.

What are the strengths and limitations of Sequence?

Pros

  • Unlimited wallets at every tier — perfect scalability for the ecosystem without having to pay per user.
  • Security of Smart Sessions — allows you to isolate the permissions of each app and prevent malicious access.
  • Single Unified Address — prevents fragmentation in addresses across different applications and chains.
  • Gaming Optimized SDK's — supports Unity, Unreal, Web to build immersive gaming experiences.
  • Branded Ecosystem Wallet — can be hosted on your domain, fully customizable.
  • Hardware TEE Security — uses AWS Nitro Enclaves with attestation from Quantstamp/CoinCover.
  • Seamless Onboarding — supports social login, email, passkey without any authentication configurations needed.
  • Cross Chain By Default — includes built-in swap functionality, on-ramp capabilities, portfolio view.

Cons

  • Pricing Not Transparent — requires sales contact to get pricing, difficult to plan for small teams.
  • Ecosystem Focused — less desirable for single app devs who just need a basic wallet.
  • Currently Only EVM Support — does not natively support Solana or any other non-EVM chains.
  • Complexity of Self Hosting — requires significant engineering resource to develop using the Wallet Development Kit.
  • Limited Individual Wallet Features — designed for platform use, not for personal wallet usage.
  • Dependent on Sequence Infrastructure — potential for vendor lock-in when using hosted wallets.
  • Relatively New to the Market — newer than Safe which has been around longer.
  • No Public Pricing Tier — makes it hard to evaluate cost prior to making a commitment.

Who Is Sequence Best For?

Best For

  • Gaming ecosystems and publishers — SDK's for Unity/Unreal & Unified Wallet Across Multiple Titles Boost Retention.
  • Chain growth and DevRel teams — Branded Wallet is Developer Hub Attracts Apps to Your Ecosystem.
  • DeFi platforms with multiple protocols — Eliminates Liquidity Fragmentation Across Apps.
  • App platforms with 10+ integrated applications — Unlimited Wallets Scale Cost Effectively For High Volume Ecosystems.
  • Teams building branded wallet experiences — Hosted Wallet on Custom Domain With Full UI Customization.

Not Suitable For

  • Single app developers — One App Will Be Too Much; Use A Simpler Embedded Wallet Like Dynamic or Web3Auth.
  • Individual retail traders — Personal Focused; Use Consumer Wallets Such As MetaMask or Argent X
  • Non-EVM projects — Currently EVM-only; Consider Solana native wallets or cross chain alternatives
  • Budget-conscious startups — Opaque pricing model; Start with free / open source wallet contracts

Is Sequence Worth It?

The sequence is a delivery system for producing ready-to-use smart wallet infrastructures that are designed to resolve the three major issues associated with the UX of Web3 — fragmentation, friction in the onboarding process, and signature fatigue. By using an ecosystem wallet-based approach, that has an embedded SDK for all platforms, sequence can position itself as the infrastructure for all types of chains, games, and applications for DeFi, instead of being viewed as a consumer wallet. With enterprise-level security and the ability to provide cross-chain functionality, it is capable of supporting serious production implementations.

What Are the Best Alternatives to Sequence?

  • •
    Privy: A simple embedded wallet solution that allows for a seamless social sign-up process using passkeys. Less complex to set up compared to Sequence, however, it is missing some of the same ecosystem capabilities as Sequence. Good for dApps looking to quickly integrate their wallet while focusing more on the wallet itself rather than having a large amount of the total infrastructure. (privy.io)
  • •
    Dynamic: A smart account infrastructure that has a wide range of blockchain support and also supports embedded wallets. Has a wider range of blockchain support than Sequence but does not have as much gaming-focused support. Best for DeFi protocols that need maximum support from all the different blockchains they may be operating on. (dynamic.xyz)
  • •
    Arcana Network: An embedded authentication feature with gasless transaction options and social account recovery. Provides a strong mobile option and competes with Sequence's SDKs in React Native. Best for mobile first Web3 applications that want to make user account creation as easy as possible. (arcana.network)
  • •
    Web3Auth: A multi-party computation (MPC) based wallet infrastructure that provides users with an option for social-based login and threshold-based security. Offers more customizability in how keys are managed compared to Sequence's enclave model. Best for white label wallet solutions for various blockchains. (web3auth.io)
  • •
    Biconomy: A platform for account abstraction that offers users paymaster and bundler services. Allows developers to create more fine-grained control over account abstraction compared to Sequence's focus on providing a wallet. Best for use cases that require more advanced use of account abstraction compared to embedded wallets. (biconomy.io)
  • •
    Particle Network: A universal account layer that provides users with access to all accounts in a single place through its chain abstraction. Supports a broader array of blockchains compared to Sequence's ecosystem. Best for developing applications that allow users to easily switch between multiple blockchains and unify all of their accounts into one single account. (particle.network)
