HOW IT WORKS

Lotero is a provably fair, on-chain slot machine built on Base. Every spin is verified by Chainlink VRF (Verifiable Random Function), making it impossible for anyone to manipulate the results.

How to play

1
Connect your wallet

Connect any wallet that supports Base network (MetaMask, Coinbase, etc.)

2
Have USDC on Base

You need at least 1.1 USDC in your wallet on Base network to play

3
Hit SPIN

Sign the payment authorization in your wallet. No gas needed — the agent handles everything

4
Wait for result

Chainlink VRF generates the random numbers on-chain. Results appear in a few seconds

5
Claim your wins

If you win, your earnings accumulate and you can claim them anytime

Pay table

Match 3 of the same symbol to win. Each spin costs 1 USDC (+ 0.1 USDC service fee).

BNBBNB x 314 USDC
ETHETH x 320 USDC
BTCBTC x 330 USDC

Provably fair

Every spin uses Chainlink VRF 2.5 to generate verifiable random numbers on-chain. This means:

  • No one can predict or manipulate the outcome — not even the developers
  • Every result can be verified on the blockchain
  • The smart contract is open-source and auditable
  • The RTP (Return to Player) is ~93%, hardcoded in the contract

The contract address on Base is 0xC4b8...edE9

No gas needed

Lotero uses the x402 payment protocol so you never need ETH for gas. When you hit SPIN:

  • You sign a USDC transfer authorization (not a transaction)
  • The Lotero agent receives your payment and executes the spin on your behalf
  • You only need USDC in your wallet — no ETH required
  • Your wallet may show a security warning when signing — this is normal for x402 gasless payments and does not indicate a scam
Bet amount1.00 USDC
Service fee0.10 USDC
Total per spin1.10 USDC
