In TypeScript, Rust, Go, Python, Ruby, PHP, Lua, Kotlin, or Swift. --- Why stablecoins? Stablecoins are digital dollars (USDC, USDT, PYUSD, EURC, …) that move on public payment rails. For a developer building an API, a SaaS, or an agent that needs to pay for things, they unlock a few properties that classical card networks can't match: - No middleman. Funds settle directly from payer to recipient. No gateway, no acquirer, no PSP holding the money for 2–30 days. - No 2.9% + 30¢. Network fees are measured in fractions of a cent, not percentage points. Micro-transactions stop being a rounding error. - No chargebacks. Payments are final once confirmed on-chain. Refunds happen because you choose to send one, not because a card network reversed it 90 days later. - No accounts to open. Anyone with a wallet — a person, a script, an agent — can pay. No KYC dance before the first dollar moves. - Programmable. Splits, fees, sponsored gas, subscriptions, refunds — all expressible as a transaction your server constructs. Why Solana? Solana is the most-used blockchain for payments today, and it's the one this kit is built on. - 200ms settlement. A buyer signs, your server sees the confirmation before the next render frame. - $0.0013 median fee. Stable, even when the network is busy. Predictable enough to charge $0.001 for an API call without losing money on the transfer. - $2T in stablecoin transfers per quarter.
