Issue with Custom Token Fee Estimation and Price Feed

Developer Discussion
1

Hi all

I’ve whitelisted a custom token, but I’m encountering issues with fee estimation and withdrawals for this token. Interestingly, this issue doesn’t occur with other tokens I’ve whitelisted, such as a custom USDT token, which seems to have the price feed recognized automatically.

I’m wondering if the problem might be related to the price feed — possibly the token isn’t getting one like the others. Could you help me confirm if this is the case, and if so, guide me on how I can resolve it?

Any insights would be greatly appreciated!

Hi @shubhamsharma0040 could you please share the contract address of the token you whitelisted? Could you also share the workspace you whitelisted in?

Hey @Wilfred . The token name is Monkey Token, contract: 0x2e9eBD7dC93585993d3456820426151f95957EE1

The token is on Amoy Testnet, and I work in sandbox mode.

Hi @shubhamsharma0040 can you share a screenshot of what you are seeing?

I am unable to find a balance of MNK inside the tenant AGG Group Business Consulting - George Zahariev

I do see that the asset has been listed in the workspace but no asset wallets exist.
Please see this Help Center article for more information about Asset Wallets

Hey @Wilfred I am attaching the screenshot of the error I am getting. 2 users have 99 MNK tokens right now, and I am trying to withdraw tokens from one account to the other. Also, the token is of ERC3643 type, if that helps.

From our logs we can see that there is an error in the contract - {“reason”: “Error retrieving gas limit”}

message:Error retrieving gas limit with amount = 999999999999999983222784 for contract 0x2e9eBD7dC93585993d3456820426151f95957EE1. Error = <TransactionReverted: 400 Bad Request>

Hey @Wilfred Turns out there was a hold time set in the contract and due to this, the transfer was stopped. Though I wonder why fireblocks didn’t return a proper error from the contract as it was supposed to. Anything I should change to get that response?

Thanks for the help.

Hi @shubhamsharma0040 you don’t have to change anything to get that response. unfortunately the only way is to raise the error via this community forum and we will do our best to assist developers.

We are in the process of improving the error mapping and improving the user experience.
