Testing with simulated Crypto Donations

Testing crypto via Testnet has a few limitations. Currently only tBTC is supported, and in many cases syncing is slow. To overcome these limitations, we supported creating simulated donations. Simulated donations are donations that do not happen on a blockchain but are inserted into our system manually.

Currently supported currencies for simulated donations: ETH, SOL.

Creating a simulated donation can be done using API call, or using Crypto Donation Simulator interface.

Using API call
1. Use CreateTestDonation API when you would like to create test donation programatically.
Using Crypto Donation Simulator interface
1. Visit TGB Donation Form, and initiate a Crypto donation. Make sure to select one of the supported currencies.
2. On the last step in the Donation Form, copy a deposit address.
3. Visit Crypto Donation Simulator, paste deposit address from the previous step, enter currency and amount, and click donate.
4. If everything went through successfully, the simulated donation should be visible in our system shortly.
