Senddy is free to build on. There are no plans, no monthly fee and no minimums. Senddy earns a small fee on each operation your users make, and you can add your own fee on top and keep it.
Fees per operation#
| Operation | Senddy's fee | Your fee, optional |
|---|---|---|
| Private transfer | About $0.05 | Flat, percentage, or both |
| Private swap | 0.15% | Flat, percentage, or both |
| Deposit | About $0.05 | Flat, percentage, or both |
| Withdrawal | About $0.05 | Flat, percentage, or both |
Flat fees are set in dollars and converted to each asset's units. Gas is sponsored on every operation, so your users never pay network fees. How to add your own fee is in Set your fee.

FAQ#
Do my users pay gas?#
No. Senddy sponsors gas on deposits, transfers, swaps and withdrawals.
Is there a catch for building and testing?#
No. Building, testing and running an app costs nothing until your users move money, and then only the per-operation fee above.

Yes. Write to developers@senddy.com.
