The simplest path from “user has no ETH” to “transaction confirmed”
Permissionless gas abstraction and intent execution built around wallet standards that are already shipping — EIP-7702, EIP-7710, and EIP-7715 — with the operational rigor to run in production.
No API keys, no SDK
Just point your app at relayer.1shotapi.com/relayers. No sdks, no paymasters, and no vendor sign-up - just enterprise-grade gas abstraction.
Upgrade + transact in one action
Upgrade any EOA into an EIP-7702 smart account and execute a gas-abstracted transaction in the same atomic call.
Sponsor exactly what matters
Perform 7702 upgrades, token transfers, or DeFi trades — sponsor your users or let them pay in stablecoins they already hold.
Non-custodial by design
EIP-7710 delegations are sophistcated user intents bound by scope, amount, expiry and outcome conditions. Users stay in full control of their keys and assets; you only ever see what they explicitly delegate.
The account abstraction endgame.
Save your team and your users money by upgrading to a smart account with EIP-7702. Your user grants an EIP-7710 permission scoped to your app from an EIP-7715 enabled wallet. Give the signed permission context to an agent and it can execute transactions on behalf of the user.
- Save up to 50% on gas costs compared to EIP-4337
- No prefunding - pay only when a transaction is confirmed
- Callable from any agentic environment with a simple POST request

Network fee
Let users pay for transactions in stablecoins they already have
Your users pick the token they want to pay with — USDC, USDT, USDG, etc. We bridge, swap, and settle the gas fee under the hood, even when the transaction is executing on a different network than the payment token sits on.
- Users never need native gas on the destination chain
- Transparent fee quote shown in the currency they’re paying with
- Sub 200ms response time for fee quotes and transaction sumbission
- SLAs available for high-volume integrations

- Total source code ownership - no vendor lock-in

Transparent relayer pricing with no surprises
Many providers tax growth with MAU-based pricing, charging you for users even when they do not transact. 1Shot only charges when a transaction is confirmed: flat $0.01 gas fee for any transaction payload under $0.01, and a 20% gas premium when the gas fee is over $0.01. No other charges or hidden fees.
Flat fee per transaction. Great for batching.
Premium applied to the network gas cost.
