Lovable OUSD skill

OUSD (Open USD) is a USD stablecoin issued by Bridge (a Stripe company) and governed by Open Standard. It went live on 30 September 2026 and is native on four chains. Mainnet only — there is no testnet.

Always apply

  • No contract deploys. OUSD is live; every feature is an OUSD transfer (EVM ERC-20 / Tempo TIP-20 / Solana SPL).
  • Privy for every chain. Google sign-in, embedded wallets (EVM + Solana), loaded lazily inside <ClientOnly>.
  • Read decimals on chain. Never hardcode them.
  • Real money. Show "Mainnet · real OUSD" above every pay button and default to ≤ 1 OUSD.
  • Compliance footer. OUSD is unavailable in the EEA and sanctioned regions; prohibited use cases are never built.
  • Secrets: only PRIVY_APP_ID is required. Optional server-only RPC URLs (ETHEREUM_RPC_URL, SOLANA_RPC_URL). Never use a VITE_* secret name — read secrets in a route loader.

Guides

  • Chains — per-chain setup and gotchas.
  • Privy wallets — provider config for EVM + Solana and gas sponsorship.
  • Payments — pay, split, tip and provenance patterns.
  • Compliance — geo restrictions and prohibited use cases.
  • Failure modes — symptoms and fixes.

Getting OUSD

Through integration partners (Stripe / Bridge / Privy, Coinbase, Visa, Mastercard — all mint and burn 1:1 with USD at no cost) or exchanges (Coinbase, Kraken, Uniswap).
