/v3/multitoken/transaction/batch

2 credits per API call

Transfer Multi Token Batch from account to various other accounts in one transaction. Transfer multiple Multi Tokens token from smart contract defined in contractAddress.

Multiple token with specified tokenIds and values can be transferred. This method invokes ERC1155 method safeTransfer() to transfer the token in case of ETH, Celo and BSC.

This API is supported for the following blockchains:

• BNB Smart Chain
• Celo
• Ethereum
• Harmony
• Klaytn
• KuCoin Community Chain
• Polygon
• Flare
• Cronos
• Base
• Avalanche
• Fantom

Signing a transaction

When transferring multiple Multi Tokens, you are charged a fee for the transaction, and you must sign the transaction with the private key of the blockchain address from which the fee will be deducted.

Providing the private key in the API is not a secure way of signing transactions, because the private key can be stolen or exposed. Your private keys should never leave your security perimeter. You should use the private keys only for testing a solution you are building on the testnet of a blockchain.

For signing transactions on the mainnet, we strongly recommend that you use the Tatum Key Management System (KMS) and provide the signature ID instead of the private key in the API. Alternatively, you can use the Tatum JavaScript client.
