Multiple Issues with Revolut Wallet Sync (Transfer + API Warnings)

Koinly Support
1

Hi,

I’m seeing several issues flagged in my Revolut wallet and would like clarification so everything is reconciled correctly.

  1. Missing purchase history warning
  • Koinly shows:
    “Missing 0.04632786 BTC on 2023-06-06 18:44:11 UTC.”
  • On that date, I transferred approximately 0.046 BTC from Revolut to a self-custody Ledger wallet that I control.
  • This was a transfer, not a sale.
  • I attempted to manually add a receiving wallet to reconcile it, but the system is still flagging a missing cost basis.
  • There appears to be a slight amount discrepancy between the sent amount and what Koinly flags as missing (possibly fees or API rounding).
  1. API upgraded warning
  • The wallet was created using an older API version.
  • Please confirm whether re-adding the wallet is recommended to ensure historical accuracy.
  1. No crypto deposits found
  • The wallet indicates no crypto deposits were detected.
  • I want to confirm that my full acquisition history is being captured correctly and that cost basis is not incomplete.
  1. API limitations notice
  • I understand the fiat balance discrepancy warning may not affect crypto gain calculations, but I’d appreciate confirmation that it does not impact capital gains reporting.

My objective is to ensure:

  • The June 6, 2023 transaction is treated as a non-taxable self-transfer.
  • All cost basis data is complete and correctly calculated.
  • My 2025 capital gains report reflects accurate FIFO treatment.

Please advise on the cleanest way to resolve these issues (API re-sync vs full CSV re-import).

Thanks

Hi @Ian_Murphy

I suggest you delete the wallet and recreate it as you have the “API upgraded” warning:

API sync: “API has been upgraded” warning on the troubleshooting page
