Payments

SDP provides a Solana-native payments stack: stablecoin transfers, fiat on-ramps and off-ramps, wallet policies, and reconciliation primitives. This section mirrors the structure of the public Solana payments documentation and maps each workflow to the SDP APIs you call to ship it.

If you have not yet provisioned a custody wallet or token, start with Set Up Wallets and Tokenize an Asset.
