NFT(ERC721) estimateGas?

@TheGreatAxios Thank you for answer.

This is my fault.
The same to: address was used.
I separated the to: address, and it works fine.
(contract address, wallet address)

...
final contractFunction = contract.function('safeTransferFrom');
        return await client.estimateGas(
          sender: EthereumAddress.fromHex(from),
          to: EthereumAddress.fromHex(contract address),
          data: contractFunction.encodeCall([EthereumAddress.fromHex(from), EthereumAddress.fromHex(wallet address), tokenId, Uint8List.fromList([])]),
          gasPrice: EtherAmount.inWei(gasPrice),
          amountOfGas: gasPrice,
          value: EtherAmount.inWei(BigInt.from(1)),
        );
...        

The gasLimit is similar to 90,000. (real 87,933)

Thank you very much.
Have a good day.

your code is ok. change your rpc url

@ttb-inc Is it working? if not, what network are you using?

@TheGreatAxios
It still doesn't work.

[Network]
80001 (Polygon Testnet(Mumbai))
(https://docs.polygon.technology/docs/develop/network-details/network/)

[RPC Endpoint]
RPC Endpoint tested two things.

1. https://rpc-mumbai.matic.today/
2. Supported by Moralis. (https://speedy-nodes-nyc.moralis.io/[API_KEY]/polygon/mumbai)
   Both of the above result in the same result.

Thank you.

@ttb-inc Please send your code here, I will take a look. Currently, I am having no issues estimated gas on Mumbai; so it may be something related to your setup/config.

NOTE: DO NOT UPLOAD ANY API KEYS when you upload your code (Just a reminder :)) I see you commended the one out above

          gasPrice: EtherAmount.inWei(gasPrice),
          amountOfGas: gasPrice,
          value: EtherAmount.inWei(BigInt.from(1)),
        );
...        

If there is no problem with the above code, I will check it again.

Let me create testable code.
Thank you.

@ttb-inc Is this for an ERC-1155 or an ERC-721?
Also, can you please provide the error.

Thanks
