solidity integration with sendToken, but tokens does not arrive on the destination

[devton]

Hi,

I've testing this contract snippet that I've created, but when I execute the the function to send tokens to Polygon destination chain the tokens does not arrive:

contract that I'm using:

https://github.com/devton/solidity-snippets/blob/main/AxelarIntegration.sol

The transaction was successful, the axlUSDC goes to the 0x00000 on base chain but not arrive on the Polygon destination.

@devton, could you please share the txn hash?

Thank you for sharing the transaction hash, but it seems that there was an error that says "insufficient transfer fee." This indicates that the amount you want to transfer is too small. You can check the details of the error here at https://axelarscan.io/transfer/0xbb9b44cd3088c7e68058e9664530abc209db19225a955316af18985e610ff37d.

This is a mainnet txn, it might be better to test things out on the testnet first. The testnet doesn't require an actual fee, just a faucet, before you push to the mainnet.

thanks @Olanetsoft I've forgot to check on the axelarscan, about this one the transfer fee would be 11.5 axelUSD? "Transfer Fee: 11.5", how I can calculate the transfee fee before send the tokens? and if I want to recover this 0,81 axlUSD I just need to add this 11.5 amount into the contract balance or is just gone?

@devton to calculate the transfer fee, you can use our JS SDK to do that as referenced here. To recover this txn, you can add more gas for it to go through using this API.
