Create Fungible Token Transaction Request From Address Without Fee Priority

POST
/wallet-as-a-service/wallets/{walletId}/{blockchain}/{network}/addresses/{senderAddress}/feeless-token-transaction-requests

Through this endpoint customers can make a single feeless token transaction on the Tron blockchain protocol. TRX transactions burn certain resources called Bandwidth and Energy. Each account has 1500 bandwidth free for use every 24 hours and more can be obtained by staking TRX. The unit price of Energy is 280 SUN and of bandwidth - 1000 SUN. If the resources are insufficient, TRX will be burned to pay for them.

Path Parameters

blockchain string Required

Represents the specific blockchain protocol name, e.g. Ethereum, Bitcoin, etc.

network string Required

Represents the name of the blockchain network used; blockchain networks are usually identical as technology and software, but they differ in data, e.g. - "mainnet" is the live network with actual data while network like "nile" is a test network.

senderAddress string Required

Defines the specific source address for the transaction.

walletId string Required

Defines the unique ID of the Wallet.

feeLimit string Optional

Fee limit of the smart contract. If "OUT_OF_ENERGY" error appears - It is necessary to check whether the address of the calling contract has TRX and whether it is enough to pay for the burning energy or bandwidth cost, otherwise the address needs to obtain enough TRX. If there is enough TRX, the feeLimit set by the transaction is smaller, and it needs to be increased.
