A checkout that lets users top up OpenRouter using USDT, USDC across BNB Chain, Ethereum, Solana, and Stellar or Bitcoin.
I started with a clear goal: make topping up OpenRouter possible through more cryptocurrencies and networks. We structured the experience around choosing an asset, selecting a compatible chain, and completing payment with minimal friction. The AI helped shape the interface, implementation, and edge-case handling, while I decided which currencies, networks, and user flow to support. The result is a focused checkout that turns a complicated multi-chain process into a straightforward transaction.
Can I top up OpenRouter with sats?
Yes. You can top up with sats over the Bitcoin Lightning Network: http://checkout.rozo.ai/btc
Smooth run—the narrow scope and clearly defined payment combinations kept the build focused and avoided major design detours.
I began with the desired user outcome, then refined the build feature by feature. Prompts focused on one decision at a time—supported assets, networks, checkout behavior, and presentation—so each iteration stayed easy to evaluate.
