Transak One

Note: All the query parameters marked with *(asterisk) are mandatory to send to successfully load the widget and complete the transaction.

If your smart contract will be sending some kind of receipt token like Liquid Staking Tokens (LST) back to the user wallet, you need to pass the details about that token in "cryptoCurrencyData".

If you are not sending any token back to the user, you need not send the "cryptoCurrencyData".

More details can be found in the Product docs here.

00a261da49......
stringThe calldata/hex that needs to be passed to your smart contract in order to execute the required function successfully.

The calldata should contain the method ID of the function to be executed and the values of all the parameters in that function.

Note: You need to compress the calldata and send the output as the value for this query param. Detailed explanation here.
network *EthereumstringA crypto network that you would allow your customers to buy NFTs on. You can get the list of supporting networks here. For ex: Ethereum
estimatedGasLimit *34589000numberGas limit that needs to be filled while executing the transaction

Note: This cannot be 0
smartContractAddress *0x86349020e9394b2BE1b1262531B 0C3335fc32F20stringThe address of the smart contract on which the calldata needs to be executed
cryptoCurrencyDataExampleDetails of the crypto user is going to receive after they do the transaction.

Taking example of Aave, if you deposit USDC in a staking pool, user will receive AUSDC in return.

So details about AUSDC token needs to be sent in this query parameter.
sourceTokenData *Example The code of the cryptocurrency that your smart contract accepts in order to execute the function.

Taking above example of Aave, if you deposit USDC in a staking pool, user will receive AUSDC in return.

The wallet address needs to be valid for the blockchain network so to make sure this works you should pass cryptoCurrencyData or network.

This wallet address passed here should be same as the one used to generate the calldata. As the receipt token will be sent to the address mentioned in the calldata.
