Polygon NFT ist an Trezor/Metamaske hängen geblieben.

Ich habe also eine NFT in meine Trezor-Metamaske fliegen lassen. Die NFT ist im Polygon-Netzwerk und jetzt steckt sie fest. Anscheinend unterstützt trezor/metamask keine Polygon NFT’s. Ich habe zwei mögliche Lösungen gesehen.

1. Eine ist das Importieren meiner Seedphrase in eine neue Wallet, aber das kompromittiert dann meinen trezor.

2. Die andere ist, einen Ledger zu kaufen und das Konto darauf zu importieren. Ledger hat dieses Problem offenbar nicht.

Es ist eine Schande, da ich Trezor bis jetzt geliebt habe.

Gibt es Alternativen?

I sent an ERC-1155 to my Trezor wallet not realizing it was not supported in Suite. I assume it’s still in wallet and secure even though the token shows 0? and error symbol says: We had trouble loading your token balances. You can view them here

And what is the best way to send it back to Metamask wallet if I would like to? I attempted once but never went through (even with sufficient funds I think) and ultimately cancelled the transaction.

Looks like you and u/Dubmanz are in the same boat.

> Apparently trezor/metamask does not support Polygon NFT’s

I’ve seen that asserted, but I’m not totally convinced that the coins are burned. I know Trezor Suite doesn’t support Polygon NFTs, but imagine that Polygon ERC-721 assets use the same signing mechanics as Ethereum ERC-721 assets. If that is true, there should be a path out. Unfortunately I don’t own any Mumbai NFTs that I can test with. There are a few things that would be useful to know for sure:

1. The NFT contract address
2. The exact Polygon chain (assume EIP-155 id:137)
3. The derivation (possibly `m/44’/60’/0’/0/0` or `m/44’/966’/0’/0/0`)
4. The NFT type (ERC-721 or ERC-1155)

I know Trezor firmware supports EIP-155, EIP-712, EIP-1559, [ERC-20, ERC-721 and ERC-1155](
https://github.com/trezor/trezor-suite-guide/blob/c534aa9/en/supported-crypto-assets/eth-tokens.md
), but not all through Suite. The wallets that can do token / NFT transactions against the Trezor firmware are MetaMask, MyEtherWallet, MyCrypto and TrezorCTL. Of all of these, TrezorCTL is likely to most updated in regards to Trezor, but is difficult to use. What’s more, both MyEtherWallet and MyCrypto can touch Trezor either directly, or via MetaMask. You would want to take MetaMask out of the mix if that is causing problems.

TrezorCTL will accesses the firmware directly via USB. All the other wallets go from

Wallet->TrezorConnect->TrezorBridge->TrezorFirmware

There are some known issues with Metamask both in the „Wallet“ layer and the „TrezorConnect“ layer in regards to EIP-712. My first suggestion would be to update everything, turn off Trezor [safety-checks](https://wiki.trezor.io/Using_trezorctl_commands_with_Trezor#Safety-checks), enable Trezor [experimental-features](https://github.com/trezor/trezor-firmware/pull/1297), then try to move the coins through MyEtherWallet, MyCrypto, or TrezorCTL. Take heed of the first four points, knowing all that info is more important than most realize.

If you choose to abandon Trezor entirely and expose your seed-mnemonic, you should take great care to move EVERYTHING but your NFTs before anything. Once done, you may be able to access your NFTs through the following ways:

1. Enter your Trezor Seed and Passphrase into a Ledger
2. Enter your Trezor Seed and Passphrase into MetaMask
3. Enter your Trezor Seed and Passphrase into MyEtherWallet
4. Enter your Trezor Seed and Passphrase into MyCrypto

Of course you will need the first four points here as well in case the auto-detect of chains and assets doesn’t work.
