Kevo submits and tracks the tx hash

Smart accounts without changing the wallet address.

Kevo uses an EIP-7702 smart-account path for supported embedded EVM wallets, so the account can execute UserOperations while preserving a familiar EOA-style address experience.

  • Same user wallet address
  • UserOperation execution path
  • Authenticated signing before submit

Kevo policy methods

Sponsor only what your policy allows.

Before a sponsored transaction is submitted, Kevo checks the chain, target contract, value, rate limits and monthly sponsor budget configured for the project.

  • Allowed chains and contracts
  • Per-user and project gas budgets
  • Hourly transaction limits

Policy checked before sponsorship

Graceful fallback when sponsorship is unavailable.

If a chain is unsupported, the policy rejects the action, or the project budget is exhausted, your app can fall back to a regular user-paid transaction flow.

  • Project-funded execution when eligible
  • Submitted transaction tracking
  • SDK flow stays unified by chainId

Account abstraction

A smoother transaction layer, controlled by your budget.

Turn on smart accounts, fund your sponsor wallet, and let Kevo enforce the policy before eligible sponsored transactions are sent.
