SolSettle

Automated stablecoin settlement and payout API for Solana merchants expanding across borders.

Merchant payment infrastructure on Solana lacks a dedicated settlement layer despite surging USDC liquidity and large merchant adoption; existing tools focus on swaps or cross-chain messaging, not automated stablecoin payouts.

Why Now

Stablecoin liquidity is accelerating: Circle minted $500M USDC on Solana as total stablecoin supply surpassed $15B, and KSNeT's MOU will bring Solana Pay to 330,000 merchants. Yet Infrastructure has only 8 tracked projects and none address automated cross-border settlement flows. The upcoming Webinar: Cross-Border Payments on Solana signals growing developer demand for exactly this.

Suggested First Step

Prototype a devnet API that splits incoming USDC between merchant treasury and payout wallets, then test settlement with 5 volunteer merchants from KSNeT's network.

Go Further

"I'm building SolSettle, a stablecoin settlement API for cross-border merchants on Solana. The signal: $500M USDC minted, 330K merchants via Solana Pay, and only 8 infrastructure projects tracked. Help me scope an MVP that uses Solana Pay for settlement — should I build a smart contract escrow or just use a wallet/payment splitter? What are the top 3 tech risks to validate first?"
