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.

Supported Web3 domains:

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

Example of Domain Lookup

• vitalik.eth → 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
