Bridging from Polygon to Solana doesn't work

Brave Wallet (Self Custody)
1

I have tried to bridge half of my MATIC tokens and convert them to SOL on the Solana Mainnet Beta, however I have not received anything on the Solana side yet. It has been approximately one hour since I originally used the “Bridge” feature directly in the Brave Wallet, and the transaction has gone through on the Polygon side of things. As I am fairly new to crypto, I don’t know how long these things usually take but I feel like something may have gone wrong as I don’t think it should take this long.

Here is my transaction on the blockchain on Polygon, and here is my Solana account, which has received nothing yet at the time of writing.

From what I see, your transaction didn’t complete. https://li.quest/v1/status?txHash=0x2415762bd083b13a084d427440e50aff396fcd07d4596bda7bbb3a224c268f9d

The key pieces of information are at the very bottom of that data:

  • "status": "DONE": The bridging process is finished.
  • "substatus": "REFUNDED": This is the critical part. It means the bridge failed to send the SOL to your Solana wallet, and instead, it returned the funds to you on the Polygon network.
  • "substatusMessage": "The tokens were refunded to the user."

Where are your tokens now?

Because the bridge couldn’t complete the swap to Solana (likely due to a price change or a technical error during the process), it sent your funds back to your original Polygon wallet address.

However, if you look at the "receiving" section of that data, you will see that they weren’t sent back as native POL/MATIC. They were refunded as:

  • Token: USDC.e (Bridged USD Coin)
  • Amount: Approximately 50794 (which, with 6 decimals, is about $0.05 USD).

The bridge worked exactly as it was supposed to for a “failed” transaction. It realized it couldn’t complete the swap to Solana and safely returned your funds to your Polygon wallet. You now have about 0.05 USDC.e sitting in your Polygon wallet.

While the bridge doesn’t give a specific error code, the most likely reason is the transaction size. Most bridges have a minimum limit (often $5 to $10) to ensure the amount being sent is enough to cover the network fees on the destination side (Solana).

Since the total value here was approximately $0.05 USD, the bridge likely triggered an automatic refund because the cost to process the transaction on Solana would have been nearly as high as the transfer itself.
