How it works

Wallets are customer-owned blockchain addresses used for crypto transfers, FX settlement, and payment-link collection. Create one wallet per customer per network, then use the wallet as a source or destination in the Transfers API.

For sandbox testing, create wallets on polygon and fund them with the test funding guide.
