Smart Account Infrastructure Platform (Wallet-as-a-Service)

ZeroDev is a complete, vertically integrated smart account infrastructure stack designed for developers building Web3 applications with Web2-grade user experience. Built on Kernel — a minimal, audited, and extensible smart contract account — the platform implements ERC-4337 (account abstraction) and co-authored ERC-7579 (modular accounts standard), powering 5+ million smart accounts and $2 billion+ in monthly volume across 300+ applications on 130+ EVM chains.

Core Platform

ZeroDev provides a full-featured TypeScript SDK, a proprietary ERC-4337 Bundler (UltraRelay), a Paymaster, and a developer dashboard — enabling any dApp to embed smart account functionality without infrastructure overhead. Developers access tiered plans from free (Developer) through Growth ($69/mo), Scale ($399/mo), and Enterprise (custom).

Key Abstraction

Eliminates seed phrases by decoupling the account controller from the account itself. Supports social login (Google, Apple, GitHub), Passkeys (WebAuthn/biometrics with FaceID and TouchID), hardware security modules, and TEE-secured Passkeys for institutional use cases. Guardian recovery enables "forgot password" style key rotation without permanent asset loss.

Gas Abstraction

Removes the requirement for users to hold native gas tokens. Full gas sponsorship allows developers to cover transaction fees entirely via the Paymaster; ERC-20 fee payment lets users pay in stablecoins (USDC/USDT) or any protocol token. Universal gas sponsorship operates across all 130+ supported chains from a single developer balance.

Transaction Abstraction

Transforms multi-step transaction flows into one-click experiences. Transaction batching combines multiple actions (Approve + Swap + Stake) into a single atomic UserOperation. Session keys provide temporary, granular permission tokens — analogous to JWT tokens for the wallet — enabling seamless gaming, DeFi automation, subscription payments, and AI agent-driven transactions.

Chain Abstraction

Unifies the fragmented multi-chain experience with a single Smart Account identity across 130+ EVM chains. Users never manage separate accounts or balances per chain. Chain-agnostic fee payment and universal gas sponsorship ensure a consistent gasless experience on Arbitrum, Ethereum, Base, Polygon, zkSync, Optimism, and beyond.

Smart Routing Address

A universal deposit gateway that generates a single persistent address accepting funds from any chain, CEX, or fiat onramp and automatically routes them to the target Smart Account — eliminating manual bridging.
