How it works

Three steps to free transactions

01

Connect

Link your Pera Wallet to GhostGas. Works even with zero ALGO balance.

02

Watch Ad

A 5-second sponsored ad plays. The agent records your impression on-chain as proof.

03

Transact

Your transaction is fee-pooled with a sponsor. Confirmed on Algorand, zero fees paid.

Features

Built for Algorand, not a wrapper

On-Chain Attestation

Every ad impression is recorded as a cryptographic proof in contract box storage. Advertisers can verify every view.

Atomic Settlement

7 inner transactions execute atomically: verify proof, deduct budget, split payments, fund sponsorship. All or nothing.

Native Fee Pooling

Uses Algorand's built-in fee pooling. No relayer infrastructure, no paymaster overhead. Just native protocol features.

x402 Protocol

When campaign budget hits zero, the agent returns HTTP 402 Payment Required. Clean, standards-based budget enforcement.

SDK Integration

5 lines of code for any dApp. Install @ghostgas/sdk, configure your campaign, and your users transact for free.

Autonomous Agent

The settlement agent runs fully autonomously. No human trigger needed. Ad plays, agent settles, user transacts.

For Developers
