Smart wallets stopped being a research topic in 2026. Coinbase Smart Wallet hit hundreds of thousands of weekly active users, Safe crossed $100B in assets secured, and Argent rebuilt around StarkNet. Eight options now matter, and they split cleanly by who they serve: end users, treasuries, gamers, or apps embedding wallets for their customers. This guide compares the eight that ship today against the criteria that actually move a decision: account abstraction standard, signing method, gas sponsorship, multi-chain reach, recovery model, target user, and cost.

A smart wallet is a contract account, not an externally owned account. That means the signing key is decoupled from the address, transactions can be batched, gas can be paid by someone other than the sender, and recovery does not require a 12-word phrase. The dominant standards are ERC-4337 for greenfield contract accounts and EIP-7702 for upgrading existing EOAs into smart accounts on Pectra-era Ethereum.

The default consumer pick. Coinbase Smart Wallet is ERC-4337, passkey-native (WebAuthn signs every transaction with Face ID or Touch ID), and free to deploy. On Base, users can pay gas in USDC instead of ETH, which removes the single biggest onboarding cliff. It supports Base, Ethereum, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, and Zora.

Recovery works through the passkey itself, which syncs across iCloud Keychain or Google Password Manager, plus an optional recovery key the user can stash. There are no app downloads — the wallet runs at keys.coinbase.com and any app integrating the SDK gets popup-based signing. Source: Coinbase Wallet docs.

Safe (the rebranded Gnosis Safe) is the institutional anchor. It secured roughly $100B in assets across 15+ EVM chains as of early 2026 and remains the default choice for DAO treasuries, protocol multisigs, and corporate crypto operations. The wallet enforces M-of-N signature thresholds — typical configs are 2-of-3 for small teams or 5-of-9 for large DAOs.

Safe added ERC-4337 support through its 4337 module in 2024, which means Safe accounts can also use bundlers and paymasters. The trade-off: Safe is built for deliberate, multi-party transactions, not consumer speed. Deployment costs gas (a few dollars), but there are no protocol fees. Source: Safe documentation.

Argent pivoted decisively to StarkNet. Argent X is the StarkNet-only wallet that takes advantage of StarkNet's native account abstraction — every account on StarkNet is a contract account by default, so Argent doesn't need a 4337 bundler stack. It uses guardian-based social recovery (a phone, an email, or a friend's wallet can help recover) and supports session keys for dApps that want one-tap interactions.

If your activity is on Ethereum L1 or other L2s, Argent X is not the right pick. If you're trading on Ekubo, AVNU, or Nostra, it is the best wallet on StarkNet by a wide margin. Source: Argent X docs.

Soul Wallet is an open-source ERC-4337 wallet that emphasizes passkey signing plus guardian-based social recovery. It is closer to Coinbase Smart Wallet in shape than to Safe, but it ships as a self-custody browser extension and web app rather than a Coinbase-branded product. Supported chains include Ethereum, Arbitrum, Optimism, Base, Polygon, and BNB Chain, with paymaster integrations for sponsored gas.

The audience is users who want a passkey smart wallet without tying their account to a centralized brand. Source: Soul Wallet docs.

Biconomy is not a wallet for end users — it is the infrastructure other apps embed. The SDK ships a 4337 bundler, a paymaster service, and modular smart-account templates that support both ERC-4337 and EIP-7702 flows. Apps can plug in any signer (passkey, EOA, MPC) and get gasless transactions, batched calls, and session keys without running their own infra.

Pricing is usage-based per UserOperation, which makes it suitable for apps that want to predict costs as they scale. If you're building a wallet, Biconomy is a competitor to Pimlico, Alchemy Account Kit, and ZeroDev. Source: Biconomy docs.

Sequence is built for game studios. It supports email and social login, session keys (so a game can pre-authorize many transactions in one signing event), and gas sponsorship in either native gas or in-game tokens. It runs across 14 EVM chains including Base, Arbitrum, Polygon, and several gaming-focused L2s.

The technical design is a custom modular smart account with optional ERC-4337 compatibility. The pricing is tiered SaaS — free up to a certain MAU, then per-seat or per-transaction. Source: Sequence docs.

Privy is the auth-provider-shaped wallet. It embeds wallets behind email, SMS, social, or passkey login, defaults to an embedded EOA for speed, and offers an upgrade path to ERC-4337 or EIP-7702 smart accounts when an app needs gas sponsorship or batched calls. It supports both EVM chains and Solana.

Pricing is monthly-active-user based, which fits B2B SaaS pricing models. Privy's pitch is that consumer apps can ship a wallet without users ever knowing they have one. Source: Privy docs.

Magic predates the 4337 era. Its core product is email magic-link authentication that produces an embedded EOA, with optional account-abstraction features bolted on. It supports 25+ chains including non-EVM networks like Solana and Flow, and offers a paymaster add-on for sponsored gas.

Magic is the right pick when an app needs broad chain coverage and Web2-shaped auth, and a less obvious pick if the app is EVM-only and wants modern AA primitives from day one. Source: Magic docs.

If you are an end user on Base or Ethereum, Coinbase Smart Wallet wins on cost and onboarding. If you run a treasury, Safe is the only serious choice. If you live on StarkNet, Argent X. If you are an app embedding wallets for your customers, the question is whether you want infra (Biconomy), a gaming-tuned stack (Sequence), an auth-provider shape (Privy), or maximum chain coverage (Magic.link). Soul Wallet is the open-source alternative for users who don't want the Coinbase brand on their account.

Every smart wallet on this list except Argent X (which has its own StarkNet model) uses an ERC-4337 paymaster, EIP-7702 sponsorship, or a hybrid. The wallet builds a UserOperation, the paymaster signs off on paying the gas, the bundler submits it onchain. The user can pay in USDC, in an app's native token, or pay nothing if the app sponsors. The mechanics are uniform across wallets — what differs is whose paymaster signs and who pays the bill.
