TON based wallet has different type as we generally use for KIP7. Please refer to the scripts' hashPart for switching your address to 32byte address
https://github.com/jaybbbb/bridge-utils​
amount : 1 
Basically, you are sending the minimum amount to register the token, 1/10^18 since the contract is based on the standard of decimal 18
Send Transaction referring to the Send Transaction using Metamask step
You can check the bridged token by searching for toAddr in toChain's explorer
If the chainFee shows any gas fee, put the same amount in the GAS FEE value
When the transaction is completed, tochain's explorer shows the result as above
