Can access to USDC on the ARB network be obtained through a trustline in Xaman?

No, and here's why:

  • Trustlines only work on the XRPL, not on Arbitrum or Ethereum.

  • The USDC you sent is on the Arbitrum network, not XRPL.

  • There is no trustline for USDC on the XRPL in the Arbitrum network — these are different blockchains.

Is there a chance to recover the funds?

Yes, if:

  1. You have the private key or seed phrase from the Xaman wallet.

  2. You import it into a wallet compatible with Arbitrum, such as MetaMask.

  3. If the address matches and the funds have indeed arrived, you will gain access to them.

✅ What needs to be done:

  • Check if you can export the private key or seed phrase from Xaman.

    • If yes: import it into MetaMask, connect to the Arbitrum network, and check the balance.

    • If no: you will most likely not be able to access the funds.

🚫 Gatehub offers recovery for $500 without a guarantee — most likely, they will try to do the above using their tools.


Steps for self-recovery (if you have access to the seed phrase):

  1. Install or open the MetaMask wallet.

  2. Import the wallet using the Xaman seed phrase.

    • (Important: only if this is a standard 12/24-word BIP-39 format phrase).

    • Add the Arbitrum One network to MetaMask.

  3. Compare the address with the one you sent USDC to.

  4. If the address matches, open arbiscan.io and check the USDC balance.

  5. If the funds are in place — you will be able to transfer them to another wallet.

If you do not have access to the private key

  • Unfortunately, the funds are likely lost unless:

    • Gatehub cannot recover them (which is not guaranteed).

    • Or KuCoin somehow does not cancel the transaction (which is almost impossible in reality).

Summary

  • Trustline won't help — they only work on XRPL.

  • The possibility of recovery depends on whether you have the seed phrase/private key from the Xaman wallet.

  • Try importing the phrase into MetaMask and checking on the Arbitrum network.

  • Gatehub is the last option, but it's expensive and without a guarantee @Cryptoland_88
