2Settle update: crossed $583K processed this year moving crypto to fiat across BTC, ETH, and Tron. Every user gets their own HD wallet, and each incoming transaction runs a fraud detection pass before it settles. The tricky part was never the chains. It was making settlement feel instant while on-chain confirmations lag behind. We landed on optimistic settlement with risk-scored holdbacks, so clean payments clear fast and flagged ones wait.
