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.

We’ve completely redesigned the Dashboard Overview to give you a cleaner, more intuitive experience when working with Tatum Platform. Everything you need – from RPC Gateways, Notifications and Data Insights – is now accessible in one unified page.

Try the New Dashboard

RPC Gateway

Quickly start interacting with popular blockchains using pre-configured endpoints. Monitor chain health and view details for each supported network – all at a glance. Use the built-in “Try Now” widget to run live RPC calls directly from the Dashboard without leaving the page – perfect for quick tests and troubleshooting.

API Keys

Access and manage your API keys more easily to authenticate and start using Tatum’s services faster than ever.

Notifications

Create subscriptions to track blockchain events in real-time. From wallet transfers to native currency movements, set it up in just a few clicks. Keep an eye on your activity with the Sent Notifications widget on the right – it shows webhook events delivered to your endpoints.

Data Insights

Run ready-made queries to explore blockchain data instantly. Check portfolio balances, wallet transactions, or token holdings – all in seconds. Use the Quick Search widget on the right to instantly look up Wallets, NFTs, or Tokens and run insights on the spot.

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.

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 December 1, 2025, 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.

Blockchain RPC Gateway for Celo

We’re excited to introduce Web3 Name Service in Tatum’s Data API. Now you can easily resolve human-readable domains into blockchain wallet addresses across major networks. This makes it simple for wallets, explorers, and dApps to accept user-friendly names instead of long cryptographic addresses.

🔍 Try Name Service API

Supported Web3 domains:

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

Example of Domain Lookup

• vitalik.eth → 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
• rekt.eth → 0xA7499Aa6464c078EeB940da2fc95C6aCd010c3Cc
• tatumio.eth → 0xE1b2Fd65eddd29Bec2c08D6abFbD14D747F70f0e

Unichain and Monad Testnet are now supported in Tatum Notifications.

With Notifications for Unichain and Monad Testnet, you can build real-time DeFi protocols, NFT marketplaces, DAOs, and analytics platforms – all without running your own infrastructure. Simply subscribe to blockchain events, receive clean structured alerts, and keep building.

### **Available Notification Types**

• Finality-based Alerts: Be notified when transactions are mined, confirmed, or finalized

We’ve added HyperEVM support to Tatum's Blockchain Gateway! You can now start building on the HyperEVM Mainnet and Testnet via Tatum’s managed RPC gateway using familiar Ethereum JSON-RPC methods.

HyperEVM is an Ethereum-compatible Layer 2 built on the Hyperliquid ecosystem, designed for ultra-low latency, high throughput, and low-cost transactions. With full EVM compatibility, it enables developers to deploy smart contracts and dApps without changing their existing Ethereum tooling. Ideal for DeFi, NFTs, and on-chain trading applications, HyperEVM provides performance and scalability without the burden of running your own infrastructure.

We’ve added Monad support to Tatum's Blockchain Gateway! You can now start building on the Monad Testnet via Tatum’s managed RPC gateway using familiar Ethereum JSON-RPC methods.

Monad is an EVM-compatible Layer 1 engineered for parallel execution, fast finality, and minimal gas fees, while preserving full Ethereum tooling compatibility. Delivering up to 10,000 TPS, ~0.5s block times, and ~1s finality, it empowers developers to build scalable DeFi apps, NFT marketplaces, DAOs, and other high-performance dApps without the burden of running their own infrastructure.
