What is Maash?
Maash is a stablecoin payment processor that lets you accept USDC and USDT payments across 8 blockchain networks through a single API. Payments are automatically bridged and settled to USDC on Solana, so you receive funds in one place regardless of which chain your customer pays on.Start here
