Vault

Web3

A self-custodial wallet that finally feels like an app — not a browser extension.

About

Why another wallet

Most wallets ask the user to think like a node operator. Vault assumes the opposite: the user wants to send money, sign in to apps, and know what they're approving — nothing else.

Built on ERC-4337 smart accounts, Vault has no seed phrase, recoverable accounts via passkeys, and gasless transactions by default through a sponsored paymaster.

Stack

  • React + Viem + Permissionless.js for the smart account layer
  • Privy for passkey-based key management
  • Pimlico bundler & paymaster
  • Tested against Base, Optimism and Arbitrum

Open source

The core account logic is open source on GitHub. Contributions, audits and bug reports very welcome.
