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

• 🔍 Get Wallet Portfolio
• 📜 Get Transaction History
• 🖼️ Get NFT Balances
• 🪙 Get Multi-Token Balances
• 🧱 Get DeFi Blocks

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.

💡

Some endpoints now include usage-based pricing to maintain high performance and prevent abuse. Pricing info is shown at the top of each endpoint page.

Action required

• Review your current integration
• Migrate to the listed endpoints
• Update your codebase accordingly to handle the updated responses

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:

🌐 Ethereum’s Pectra Upgrade Just Landed

The Ethereum Pectra hard fork introduces 11 new EIPs, bringing major enhancements across staking, transaction logic, and data throughput. 📖 Read more on Pectra Upgrade (Tatum Blog)

Tatum is fully ready. No action needed on your side. All required versions have been deployed. No downtime.
✅ Ethereum Mainnet services are fully operational.

🧪 Ethereum Hoodi Testnet Now Available

We’ve also added Ethereum Hoodi – the latest testnet in the Ethereum ecosystem – to our Blockchain RPC Gateway. Hoodi joins Sepolia and Holesky as supported Ethereum testnets on Tatum.

⛽ Hoodi Testnet

We’ve extended our Faucets collection to support developers using the new Ethereum Hoodi Testnet.

We’ve supercharged our Exchange Rate API to get the current exchange rate for exchanging fiat/crypto assets (BTCUSD, ETHUSD,...). We added new data source - CoinGecko. Prices are updated every minute.

Example response:

"value": "83413.24185600",
"basePair": "USD",
"timestamp": 1742207158192,
"source": "CoinGecko",
"id": "BTC"

We are excited to share that we have improved Malicious Address API to provide more transparency and insight into flagged addresses. We added new fields:

• Source: where the malicious report originates (Hackbounty, Blockmate, CryptoScam DB,...)
• Description: Get details on why an address is flagged as malicious (e.g., Trust trading scam site)

📢 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"
