HOW IT WORKS

Authorize. Start. Use. Stop.

Four steps. Fully on-chain. Under 30 seconds from MetaMask to internet.

01

Authorize

MetaMask signs an ERC-7710 scoped delegation. You set the maximum — not a raw transfer.

02

Start

x402 gate opens, your credential is verified. IP whitelisted. Internet begins immediately.

03

Use

Browse freely. Live timer shows elapsed time and estimated charge in real-time.

04

Stop & Pay

1Shot executes for the exact seconds used. Delegation ensures you never pay more.

TECHNOLOGY

Built on the cutting edge.

Every component is a production-grade primitive — not a demo hack.

RFC-standard

x402 Protocol

HTTP 402 native payments. No checkout, no redirect — server demands payment inline, wallet signs in seconds.

EIP-7715

ERC-7710 Delegation

Scoped smart contract delegation. Caveats enforce exact amount, target, and expiry at the contract level.

Gasless

1Shot Relay

No gas wallet needed. 1Shot executes your delegation on-chain, pays gas, and confirms via webhook.

Pay-as-you-go

Top-Up Billing

Authorize a max. Start when ready. Stop any time — 1Shot charges only the exact seconds consumed.

pfctl

IP Firewall

pfctl allowlist updated the moment payment confirms. No VPN, no login — your IP is whitelisted instantly.

Non-custodial

Zero Custody

USDC flows wallet-to-hotspot via smart contract. No intermediary ever holds your funds.

PRICING

Pay only for what you use.

Fixed plans or top-up by the second. USDC on Base. No subscription.
