When you use blockchain payments, keep the following in mind:
Funds sent to unsupported asset/blockchain pairs or to incorrect addresses may be irretrievable and permanently lost.
Make sure you send amounts above the transaction minimum. See Transaction Minimums below.
Lead does not support USDB for users in the EEA due to regulatory restrictions.

Transaction Minimums

The minimum is $3.00 on every rail — 300 minor units (for example, cents) of instructed_amount. If you submit an instructed_amount below 300, Lead rejects the payment at creation and returns HTTP 422 with an invalid_parameters entry for amounts.instructed_amount. Lead accepts only USD for instructed_currency_code — the debtor is always an account_number_id — so the minimum is the same $3.00 regardless of the destination rail or its settlement currency.
