Gasless Funding (x402)

Gavel supports gasless funding via x402, so users can participate without needing native gas on the destination chain. The goal is simple: funding an auction should feel like a checkout flow — not a “bridge + gas + wallet juggling” tutorial.

1) What gasless funding means (plain English)

Normally, to bid on Base you need:

  • the raise asset (ETH/USDC/USDT), and

  • Base ETH to pay gas

With x402, a launch can support funding flows where users don’t need to already hold native gas on Base to participate.

2) What users experience

When x402 gasless funding is enabled for an auction:

  • Users choose the auction and the raise asset

  • They fund their bid without worrying about “do I have gas on this chain?”

  • Gavel handles the payment flow so users can get into the auction smoothly

This reduces:

  • wallet fragmentation

  • failed transactions due to missing gas

  • onboarding friction for new participants

3) What x402 changes for teams

For teams launching on Gavel, x402 support helps you:

  • broaden participation (especially for users coming from other chains)

  • reduce “I couldn’t bid because I had no gas” drop-offs

  • make curated launches easier to coordinate

In practice, it’s an adoption lever: less friction → more bids → better price discovery.

4) When x402 is available

x402 funding is launch-dependent:

  • Some auctions may enable it by default

  • Others may run with standard onchain deposits

The auction page will clearly show whether x402 is supported.

hashtag
5) Important notes / expectations

  • x402 gasless funding affects how deposits happen, not how the auction clears

  • Clearing price, allocations, and settlement rules remain onchain and verifiable

  • Users should still review the auction parameters (floor price, duration, unsold token policy, allowlist/private rules)
