What's New

June 24, 2022

API v3.12.0

Support for Blockchains Deprecated: EOSIO, Lisk, Neo, Qtum, and Terra (LUNA)

We deprecated support for the following blockchains:
  • EOSIO (EOS)
  • Lisk (LSK)
  • Neo (NEO)
  • Qtum (QTUM)
  • Terra (LUNA)
What does it mean?
  • For the specified blockchains, the blockchain-specific APIs are now marked as deprecated in the API Reference. The blockchain-specific APIs are the APIs with the endpoint explicitly pointing to the blockchain, for example, https://{region}.tatum.io/v3/neo/... or https://{region}.tatum.io/v3/qtum/.... Those APIs are still usable, but we recommend that you stop using them. Eventually, we will disable and remove those APIs completely.
  • In the APIs where the specified blockchains or their assets can be used as a parameter in the request body or as a path parameter, the blockchains are no longer available in the list of available values for these parameters. For example, EOS and LUNA are no longer listed as possible values for the currency parameter for https://{region}.tatum.io/v3/tatum/rate/{currency}. Other than that, those APIs do not change in any way.
  • For EOSIO, Lisk and Terra (LUNA), you still can and will be able to connect to the blockchains directly via RPC nodes.
Need help?
If you have any question or concern regarding the deprecated blockchains, please contact Tatum Support at [email protected] or post a question in the #api channel on our Discord.

Dashboard v1.22.0

New Features on Dashboard

We added a few new features to our Dashboard. Check them out at https://dashboard.tatum.io/.
If you do not have an account yet, you can sign up here.
What’s new on the Dashboard?
The menu panel now includes the following options:
  • Explore (and its underlying options)
  • NFT Minter
  • The options under Explore let you review your assets and activities:
    • Debug This option has already been here before, we just moved it under Explore. Here, you can see the last 100 API calls that you made.
    • Deposits This option lists the deposits that you have made and received and lets you filter them by different criteria (from, to, currency, status, and so on).
    • Subscriptions This option lists your existing subscriptions and lets you create a new subscription right from the Dashboard.
    • Webhooks This option lists the last 10 webhook calls that have been made based on your subscriptions, including those that failed.
    • Virtual Accounts This option lists your existing virtual accounts and lets you filter them by different criteria (active/frozen, currency, customer ID, and so on).
  • NFT Minter allows you to mint NFTs right from the Dashboard and without the need to make API calls. You can mint NFTs for the following blockchains:
    • BNB Smart Chain (BSC)
    • Celo (CELO)
    • Ethereum (ETH)
    • Harmony (ONE)
    • Klaytn (KLAY)
    • Polygon (MATIC)
    • Solana (SOL)
Please be aware of the following:
  • All the new features use the corresponding APIs in the background (for example, listing the webhook calls under Webhooks uses the API for listing executed webhooks). Each API call consumes a specific number of credits. Please review the API Reference to see how many credits each API consumes.
  • NFT Minter runs on the API for minting NFTs and uses the NFT Express feature. When used on the mainnet, NFT Express works only with paid Tatum plans: Tatum covers the minting fee for you and then deducts the corresponding number of credits from your monthly credit allowance.

API v3.11.0

Solana and Algorand: Get the Number of Fungible Tokens per Address

For the Solana and Argoland blockchains, you can now retrieve the number of fungible (ERC-20 equivalent) tokens that a specific blockchain address holds.
To do so, use the API for getting ERC-20 tokens per address, and make sure to replace the chain path parameter with either SOL or ALGO.
https://{region}.tatum.io/v3/blockchain/token/address/SOL/{blockchain_address}
https://{region}.tatum.io/v3/blockchain/token/address/ALGO/{blockchain_address}

Solana: Get the List of NFTs per Address

For the Solana blockchain, you can now retrieve the list of NFTs that a specific blockchain address holds.
To do so, use the API for getting NFTs per address, and make sure to replace the chain path parameter with SOL.
https://{region}.tatum.io/v3/nft/address/balance/SOL/{blockchain_address}
The API returns the IDs of the NFTs connected to the address.
For a blockchain address that has fewer than 50 NFTs, the API also returns each NFT's metadata. If the metadata is not returned, you can obtain it using the metadata API.

Solana: Manage SPL Tokens

For the Solana blockchain, you can now manage SPL (Solana Program Library) tokens.
SPL tokens are Solana-specific fungible tokens equivalent to the Ethereum ERC-20 tokens.
Here is what you can do:
