Documentation - Simplified blockchain navigation

We’ve streamlined our documentation to help you find what you need faster.

Blockchain functionality is now organized by interfaces (e.g., Tatum API, JSON-RPC, Rosetta, gRPC REST). This makes it easy to locate methods and see supported features for every blockchain.

We’ve revamped our documentation to make finding what you need faster and easier.

We’re excited to announce the launch of Bitcoin Testnet4.

Bitcoin Testnet 4 provides a reliable and risk-free environment for developers, miners, and users to experiment with Bitcoin applications. This new testnet addresses significant limitations of the deprecated Testnet3, including challenges in acquiring testnet coins and issues with network stability. Testnet4 features improved mining activity, more predictable difficulty adjustments, and reduced network abuse, ensuring a seamless testing experience.

Bitcoin Testnet4 Support

  • Tatum integration: Integrated with Core API, Dashboard and SDK
  • Bitcoin testnet4 endpoint (⭐ Tier 2): https://bitcoin-testnet4.gateway.tatum.io

Transition to Testnet4 and unlock new opportunities to innovate on the Bitcoin network!

As part of our ongoing efforts to deliver improved performance and operational stability, we’re excited to announce an upgrade to Binance Smart Chain (BSC) RPC infrastructure.

⏱️ All nodes will operate exclusively on Erigon since Tuesday, November 26.



Why Erigon?

The migration to Erigon enables us to provide better overall node stability, lower latency, and a more robust experience for your applications. Erigon nodes have already been used for debug methods, and now they will fully replace Geth nodes for all operations. This change allows us to improve service quality. However, some changes in RPC method compatibility may impact certain integrations.

🚧

Deprecated and Unavailable methods:

  • eth_feeHistory: Modified structure; Erigon now provides more detailed information.
  • txpool_inspect: Not available on Erigon.
  • txpool_status: Includes a new parameter baseFee.

We encourage users to review their current usage. If you’re using eth_feeHistory, note that its structure has changed, providing more granular data. Reach out to us for guidance if you experience any issues.

You can now access comprehensive balance data using our enhanced Get Balances endpoint. Previously, our supported endpoints were limited to retrieving Fungible Token Balances and Non-Fungible Token Balances. With this upgrade, the new Get Balances endpoint now also includes native balances, providing a complete view of your wallet's assets—all in a single API call.

No additional parameters are needed. Just make the call with your API key 🔑, specifying the required chain and address parameters, and you'll receive a categorized array of balances, covering fungible tokens, non-fungible tokens, and native balances.

As part of our ongoing commitment to deliver enhanced performance and stability, we're excited to announce a major upgrade to our Polygon RPC infrastructure.

⏱️ All nodes will operate exclusively onErigon since Tuesday, November 19.



Why Erigon?

The transition to Erigon enables us to provide better overall node stability, lower latency, and a more robust experience for your operations. However, this shift means some specific methods will no longer be supported.

🚧

Deprecated and Unavailable methods:

  • Deprecated: eth_sign, eth_signTransaction
  • Not available: eth_sendTransaction, txpool_inspect, eth_mining

In our commitment to delivering higher performance and stability, we’re excited to announce a significant upgrade to our Ethereum RPC node infrastructure.

⏱️ Beginning this Thursday, all Ethereum nodes will exclusively operate onErigon



This transition to Erigon allows us to improve overall node stability, reduce latency, and offer a more robust experience for your operations. However, please note that this migration means certain Geth-specific methods will no longer be supported.

🚧

Method: "txpool_inspect" will be no longer available.

These changes represent another step toward more robust and reliable service for your operations.

We’re excited to roll out Blockchain Tiering at Tatum, a new way to categorize supported blockchains based on service level, ensuring you get optimal performance tailored to your needs:

  • 💎 Tier 1: High-availability nodes with 99% uptime & 24/7 support for mission-critical applications.
  • ⭐ Tier 2: Reliable access with stable performance, suitable for professional use.
  • Tier 3: Accessible nodes for development, testing, or less-demanding apps, with gateway support.

View all details on our Supported Blockchains page. This tiering is also displayed on the Tatum Dashboard.
