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.

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.

It streamlined our services, but also required pricing adjustments.

📖

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.

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.

Supported Web3 domains:

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