We’ve released the new Tatum Postman Workspace - your central hub for exploring, testing, and integrating the Tatum across all supported blockchains. This workspace provides a complete setup for blockchain developers to build faster and more efficiently using Tatum’s RPC Gateway. It includes:

  • Test suites for all supported blockchains and endpoints
  • Ready-to-run examples for immediate testing

How to use the Postman Collection

  1. Get your API key: Visit Tatum Dashboard to obtain your free API key
  2. Import the collection: Click the "Run in Postman" button or select collection
  3. Configure your environment: Update the gateway-api-key variable in the Tatum Gateway environment
  4. Start testing: Execute any RPC method and see real-time responses

We’ve integrated Plasma into Tatum’s Blockchain Gateway, unlocking reliable RPC access to both Mainnet and Testnet. Developers can now interact with Plasma using standard Ethereum JSON-RPC methods - without managing any infrastructure.

Plasma is a Layer-1 blockchain architected specifically for stable-coin payments and high-velocity dApps. With full EVM compatibility, zero-fee USD₮ transfers, instant settlement and a native trust-minimized Bitcoin bridge, it enables developers to deploy smart contracts and scale financial applications effortlessly.

We’ve added MANTRA Chain support to Tatum’s Blockchain Gateway! You can now start building on the MANTRA Chain Dukong (testnet) and Mainnet via Tatum’s managed RPC gateway using familiar Ethereum JSON-RPC methods.

MANTRA Chain is an EVM-compatible Layer-1 built on the Cosmos SDK, engineered for parallel execution, high throughput, and minimal gas fees — while preserving full Ethereum tooling compatibility (MetaMask, Hardhat, Truffle) and supporting real-world asset (RWA) tokenization, inter-chain IBC interoperability, and regulatory-ready infrastructure.

Following Kadena’s recent announcement regarding the cessation of business operations and the discontinuation of active maintenance for the Kadena blockchain, Tatum has removed the Kadena Testnet from its supported environments.

The Kadena Mainnet remains operational and continues to be available through Tatum at this time. However, we are closely monitoring the situation and will update our documentation and platform status accordingly should any changes affect network stability or continuity.

Data Insights in Tatum Dashboard Overview

We’re thrilled to announce significant improvements to Exchange Rates in Tatum’s Data Insights.
The new endpoints deliver faster, broader, and more accurate market data, giving you real-time visibility into crypto and fiat prices.


Get Exchange Rate by Symbol

GET /v4/data/rate/symbol
Fetch the current exchange rate for a single crypto or fiat asset by symbol (for example, BTC, ETH, USD).

Explore Docs →


Get Exchange Rate by Contract Address

GET /v4/data/rate/contract
Retrieve the exchange rate for a token using its contract address on a supported blockchain. Ideal for multi-chain tokens and wrapped assets.

Explore Docs →


Highlights

  • Coverage of more than 1,000 tokens by market cap
  • Data aggregated from 10+ centralised and 100+ decentralised exchanges
  • Supports ERC-20, BEP-20, and other token standards
  • Updated as soon as tokens are listed on supported exchanges

📘

Note : Older Versions EOL Notice

Starting January 1, 2026, the v1 and v3 Exchange Rates APIs will be merged into v4. All existing calls will automatically route to v4, with no action required from users. The v4 pricing will apply going forward.

We're excited to introduce advanced filtering and search in Tatum's Error Logs page. Now you can quickly find the logs you need with precise filters and search options for all your API Errors on Non RPC Methods.

🔍 What’s New

  • Filter by API Key: View logs for a specific API key or all keys at once.
  • Search by Log ID: Quickly locate a specific request or error using its unique log ID.
  • Filter by Time Range: Narrow down logs to a custom time window, including the last 30 days.

These enhancements make it easier to debug issues, monitor usage, and gain insights from your logs in real time.

Tatum Notifications got a makeover.
Our aim was to improve service reliability and provide you with best-in-class speed:

  1. Tatum is now 4x faster at sending hooks as soon as they finalize on-chain.
  2. Our system now scales to unlimited transaction notifications.
  3. Berachain, Unichain, and Monad have been added with many more to come.

We achieved this by unifying multiple versions of our infrastructure.

📡 Try Notifications

Here's what changed:

  • Sending webhooks: 50 credits per webhook event sent
  • Daily monitoring cost: 50 credits per active notification subscription

The Celo Foundation has announced the sunset of the Celo Alfajores testnet. As a result, access to Alfajores via Tatum endpoints will be discontinued after September 1, 2025 (EOD).

To ensure a smooth transition, Tatum now supports Celo Sepolia via JSON-RPC. We recommend updating your integrations to use Celo Sepolia going forward.

Supported Web3 domains:

Added domains: .eth, .base, .arb, .bsc, .sol
