Binance API: Dust conversions use the wrong currency

planned

Jack

When I sync my Binance wallet using API, dust conversions assume that I traded dust for BNB, but in fact it was a different currency
Workaround
I need to edit those transactions manually or use CSV to import my data instead

Small amount exchange to USDC on Binance is not being reported accurately

Linas Zemaitis

This is what I see on my Binance account:
Date	Coin	Amount	Fee	Converted To
2025-10-04 13:09:50	MORPHO	0.62350976	0.02312345 USDC	1.13304945 USDC
However, the same transaction imported to Koinly via API is showing:
Summary: You traded 0.62350976 MORPHO for 1.1561729 BNB (worth €1,128.95) and paid a fee of 0.02312345 BNB (worth €22.58) on top. Your cost-basis for 0.62350976 MORPHO and the 0.02312345 BNB fee has been calculated using FIFO / Ireland (universal) from the investments listed below. Your final capital gain for this transaction is €1,127.82.
Koinly is misclasifying USDC as BNB. Please fix.
