The challenge

Crypto-native UX without a custodial fallback to a card processor.

The operator's audience expected on-chain rails: USDC and USDT deposits direct from a Web3 wallet, settlement on chain, no email-and-password gates between the player and a bet. The team was small. They couldn't afford separate integrations for sportsbook, casino, prediction markets and a fiat on-ramp. They needed one stack that handled all of it.

What we did

Stablecoin-first wallet, fiat as a parallel ramp.

Player identity is the wallet address. KYC defers to withdrawal threshold rather than gating registration. On-chain deposits and settlement run on USDC and USDT across L1 and L2 (Base, Arbitrum). Card-to-stablecoin sits next to it as a parallel on-ramp with provider-handled KYC. Casino, Turbo Sport and Polybetting all run on the same wallet on day one.

Results

By the numbers.

  • 6 weeks from kick-off to live with casino + sportsbook + Polybetting
  • L1 + L2 stablecoin rails covering USDC and USDT
  • Card on-ramp settles directly to player wallet — provider-handled KYC
  • Single team integration — one platform, one risk view
We shipped a casino, a sportsbook and a prediction-market book on stablecoin rails with a four-engineer team. The platform did the work we couldn't have hired for.
