More than wallet infrastructure.

A wallet can hold and send tokens. Kepler Cash helps your business accept payments, know who paid, track what is available, and move funds through a reliable payment flow.

Match every payment

Create a dedicated address for each customer or order and receive a signed event when the payment is confirmed.

Know what is available

See received funds, fees, and balances in exact decimal amounts without maintaining your own blockchain accounting.

Move funds confidently

Create payouts and settlements through one API, with signed webhooks keeping your system up to date.

One API across supported stablecoin rails.
