Hey,

I’m currently dealing with two connected issues on Coinbase and I’m honestly not sure if this is a system bug or something on my side.

1. USDC deposit issue

I sent 1986.197942 USDC from an external wallet (Polymarket).

• Network: Polygon
• Transaction status: SUCCESS (confirmed on-chain)
• Tx hash: 0x876c22bf2920ab4a4ae80a46598faf41237a82932802f417b7ad0342cee8b0f1

The transaction is clearly confirmed on-chain, but the deposit is not showing in my Coinbase account or history.

I also initially received an email asking to provide sender information (Travel Rule), but now I can’t access that flow anymore.

2. Identity verification issue

I’m also stuck in Coinbase identity/address verification.

• The form does not accept Slovak special characters (ž, š, č)
• After multiple attempts I get locked for 24 hours
• Even when I try ASCII-only versions, the form still rejects the input

So I’m basically stuck in a loop where:

• correct data fails validation
• retries cause 24h lock
• no alternative input method is provided

What I need help with

If anyone has experience with this or works at Coinbase, I’d really appreciate clarity on:

• Where exactly are these funds currently (on-chain vs Coinbase custody)?
• Is this a known issue with Polygon USDC deposits?
• Is there any supported format for EU addresses in KYC (without diacritics)?
• Is there a manual verification or escalation path for this?

Right now I’m basically unable to proceed due to system limitations, not incorrect data.

Thanks in advance.
