x402 Gasless Betting

Hivebets is the first prediction market platform to integrate x402 gasless betting technology, allowing you to place bets without paying any gas fees.

What is x402?

x402 is a revolutionary gasless transaction protocol that eliminates the need for users to pay gas fees when interacting with smart contracts. Instead of submitting transactions directly, users simply sign messages, and our facilitator network sponsors the gas and submits the transaction on-chain.

The Problem x402 Solves

Traditional blockchain betting requires:

• Holding extra BNB for gas fees

• Understanding gas prices and limits

• Waiting for transaction confirmations

• Dealing with failed transactions due to insufficient gas

x402 eliminates all of this.

3. x402 Facilitator Receives

   • Our facilitator network receives your signed message

   • Verifies the signature is valid
