    Login with [passkeys](/onboarding/passkeys/overview) or [social accounts](/onboarding/auth-providers), and [recover accounts](/advanced/account-recovery/sdk-recovery) if users lose their login.
  </Card>

  <Card icon="gas" title="Gas abstraction">
    [Sponsor gas](/smart-accounts/sponsor-gas/evm) for your users, or let them [pay gas with ERC-20 tokens](/smart-accounts/pay-gas-with-erc20s).
  </Card>

  <Card icon="transaction" title="Transaction abstraction">
    [Batch multiple transactions](/smart-accounts/batch-transactions) into one, no more tedious approvals. [Automate transactions](/smart-accounts/permissions/intro) with session keys, great for AI agents.
  </Card>

  <Card icon="chain" title="Chain abstraction">
    [Spend tokens on any chain](/smart-accounts/chain-abstraction/overview) without bridging, and [on/offramp with any exchange](/onramp/smart-routing-address), even on L2s.
  </Card>
</Cards>

ZeroDev can be used as a standalone embedded smart account, or alongside WaaS solutions such as Privy and Dynamic.

ZeroDev is the most trusted solution in account abstraction:
