2 credits per API call
Deploy a fungible token smart contract on the blockchain. In a deployed smart contract, you can mint and burn fungible tokens. The whole supply of fungible tokens (the supply parameter in the request body) will be transferred to the specified blockchain address (the address parameter in the request body).
Smart contracts are standardized and audited.
This API is supported for the following blockchains:
- Algorand
- BNB Smart Chain
- Celo
- Ethereum
- Harmony
- Klaytn
- KuCoin Community Chain
- Polygon
- Solana
- XinFin
- Flare
- Cronos
- Base

Signing a transaction
When deploying a fungible token smart contract, 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.
