Phosop is a seller-first payout stack built for global USDC payments. Sellers do not need SOL, gas, rent, or wallet funding before receiving payouts. They simply receive USDC directly in their wallet, while operators manage the payout flow behind the scenes.

Hey everyone! 👋 I built Phosop solo out of my own frustration with managing global seller payouts using Stripe Connect. If you’ve ever built a platform that pays out to international creators or sellers, you know the headache. With Stripe Connect, you constantly run into rigid bank payout windows, high cross-border transfer fees, slow settlement times, and regional limitations where traditional banking rails simply fall short. USDC on Solana is the obvious upgrade for instant, low-cost, global settlement. But when I looked for existing crypto payout solutions, the receiver experience was a massive bottleneck. Why should a non-crypto-native seller have to figure out how to buy SOL, transfer it to an exchange, and manage gas fees or account rent just to receive their hard-earned money? They shouldn't. That’s why I built Phosop. I wanted to create a payout stack that strips away all blockchain friction for the end-user while giving developers the familiar, reliable architecture of a modern web2 payment system. Why I built Phosop this way: Zero Friction for Sellers: Sellers receive USDC directly into their wallets. No SOL, no gas fees, and no rent funding required on their end. You, as the operator, manage the flow behind the scenes. Familiar Web2 Developer Experience: If you've worked with traditional payment APIs, Phosop will feel right at home. It’s designed around accounts, automated retries, structured logs, and reliable webhooks. Open & Self-Custodial: I didn't want to build another third-party intermediary or custodian. Phosop is software that you run yourself. You stay in full control of your wallets, ledger, and compliance processes—keeping your stack from becoming an opaque black box. Safe Sandbox Testing: You can test the entire payout flow edge-to-edge safely on devnet before switching to live USDC when your operation is ready. I built this to scratch my own itch, and I’m really excited to finally share it with you all. You can spin it up and test the full flow on devnet today.

The devnet test was smooth and the docs were easy to follow, but what really stood out was not needing any SOL or rent just to receive USDC, that has always been a pain point.

@ayaz540061 Thanks for testing it! The "no SOL/rent to receive" part is the whole reason Phosop exists — a dedicated fee payer sponsors both the gas and the associated-token-account rent, so the recipient gets the full USDC with zero prerequisites on their side. Great to hear the devnet run and docs were smooth. Would love your feedback as you push it further — feel free to open an issue or PR.
