We’re thrilled to announce that Base, the Ethereum Layer 2 chain incubated by Coinbase, is now supported in Tatum’s Data API! Base offers fast, low-cost, and secure transactions, making it an ideal environment for scalable dApps and seamless on-chain experiences.

With this integration, developers can now query on-chain data from Base using Tatum’s unified Data API endpoints. From wallet portfolios and NFT balances to DeFi blocks and transaction histories, Tatum makes it easy to build data-driven blockchain applications on Base – without managing complex infrastructure.


Available Data API endpoints for Base:

Build smarter, faster, and more reliably on Base – powered by Tatum.

We’ve made significant improvements to our Data API infrastructure
– and we’re excited to roll out new, faster endpoints that deliver better performance and richer data.

  • Up to 2.5× faster API responses across key endpoints
  • Smarter asset detection: now capturing more token types and balances
  • Increased backend scalability for improved stability and uptime

📚 Migration Guide & Important changes in API

⚠️

Deprecated Legacy Data API endpoints will be removed on June 30, 2025

To ensure continued access and performance, all users must migrate to the new endpoints by this date.
The legacy endpoints will no longer be maintained or guaranteed to function. To take full advantage of these improvements, we encourage you to start using the new endpoints listed below.

We’re thrilled to introduce SUI to the Tatum Blockchain Gateway!

SUI is a high-performance, permissionless Layer 1 blockchain developed by Mysten Labs, engineered to support ultra-fast, secure, and scalable decentralized applications.

Built with the Move programming language, SUI features a unique object-centric data model and supports parallel transaction execution, enabling low latency and high throughput — ideal for next-generation Web3 use cases like games, finance, and asset-rich dApps.

Developers can access all SUI networks - mainnet, testnet and devnet via Tatum’s RPC Gateway:

mainnet
https://sui-mainnet.gateway.tatum.io
devnet
https://sui-devnet.gateway.tatum.io
testnet
https://sui-testnet.gateway.tatum.io

We’ve expanded our TRON support as part of the Tatum Blockchain Gateway upgrade. You can now connect to TRON using: HTTP API, Solidity HTTP API, JSON-RPC or Tatum API. All interfaces now benefit from improved infrastructure and lower latency via our global RPC gateway.

📢 Now, when you check an address, you’ll have better context on potential threats! Stay safe!

Example response:

{  
  "status": "invalid",  
  "address": "0x002bf459dc58584d58886169ea0e80f3ca95ffaf",  
  "source": "CryptoScamDB",  
  "description": "Trust trading scam site"
