Bitcoin Sent to Unknown Address After Trust Wallet Purchase

Hello,

I'm hoping someone can help me understand a Bitcoin transaction that originated from a purchase made through Trust Wallet.

I purchased approximately 0.00387670 BTC through Trust Wallet/MoonPay. I did not manually enter a destination address. The Bitcoin was sent to:

bc1qq9xgfxfhazw2zqmvqswe2u6469fh7h89g9ltq0

The transaction was:

69bf9f34140a4f810bddd83378ad9eddc167bf4e2080445b806d1360b0271c13

The address received the BTC on June 19, 2026, and then on June 21, 2026, the full amount was sent out in transaction:

cd1dbea27e5e535f0e6c9855fde9b2faa962c1df83f1a18a15668bd59bed68d3 to: bc1q4f5uwlm6gw9e2z3nwphlwrpwhhhp23u2v3jz08

The blockchain explorer labels this as "Possibly self-transfer", and the output remains unspent with approximately 0.00387560 BTC.

My question is: Does this transaction pattern look like a wallet moving funds between addresses it controls, or does it look like the Bitcoin was sent to a completely different wallet? I'm trying to determine whether these addresses could have been generated by Trust Wallet and whether there is any way to identify if the destination address belongs to the same wallet.

I have already contacted MoonPay and Trust Wallet support and am waiting for a response.

Thank you for any insight.
