Building Blocks

The Tatum API is a set of building blocks for any blockchain/transactional application. It delivers prebuilt blocks available via the JSON REST API. The Tatum API is divided into 3 logical sections.


A set of API calls to access Tatum Private Ledger. Tatum Private Ledger is an abstraction layer to provide easy access to crypto/blockchain accounts and assets. In addition, it supports FIAT currencies and non-blockchain transactions (virtual currencies).


A set of API calls to directly access any supported blockchains, without any abstraction. API calls are as similar as possible between supported blockchains, which further speeds up the development of cross-chain applications.


A set of API calls that interconnect Tatum Private Ledger and blockchains. Developers can assign blockchain addresses to ledger accounts, which automatically synchronizes blockchain balances and the transaction history into the private ledger, and is accessible instantly. Tatum's off-chain solution is available for most of the supported blockchains in the Tatum API.
