Why teams choose it

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.

How a sponsored transaction flows

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.

Any stablecoin. Any network.

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

Pricing

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.

Under $0.01 gas

$0.01

Flat fee per transaction. Great for batching.

Over $0.01 gas

20%

Premium applied to the network gas cost.
