We’re excited to announce a powerful update to our Get Token Information endpoint in Tatum’s Data API — you can now fetch native token details for Ethereum (ETH), Celo (CELO), Polygon (MATIC), and Solana (SOL) directly via a single unified interface!
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
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.
Deprecated Legacy Data API endpoints will be removed on June 30, 2025To 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.
Legacy endpoints 👎 | Improved endpoints 👍 | Breaking Changes |
|---|---|---|
Get All Token Balances of an Address /v3/data/balances /v4/data/balances /v4/data/wallet/balances | Get All Assets of a Wallet | Requires at least one token type (native, fungible, nft, multitoken) |
Get Transactions | Get Transaction History | transactionIndex removed from response |
Get NFT Balances of a wallet | Get NFTs of Wallet | blockNumber removed from response |
Get all Multi Tokens that a blockchain address holds | Get Multitokens of Wallet | blockNumber removed from response |
Get Transactions by Hash /v3/data/transactions/hash | Get Transactions by Hash | No Breaking Changes |
Get Specified Blocks | Get Specific Block | Dropped eventIngestedSize, nftIngestedSize |
Get latest Block | Get Latest Block | Dropped eventIngestedSize, nftIngestedSize |
Get specified events | Get specified events | BlockRange adjusted to max of 500. |
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.
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:
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.
We’ve expanded our Blockchain RPC Gateway to Asia with a new balancer in 🌏 Singapore
– delivering significantly lower latency for users in the region, especially for “follow the tip” scenarios.
Deployment of Tatum Blockchain RPC Gateway to Singapore
🚀 5× performance boost: Chains like Tron, Kaia (Klaytn), Ethereum, BSC, Polygon, Base and others now benefit from response times reduced from ~250ms → ~50ms.
Try it now by switching to https://{network}.gateway.tatum.ioand enjoy 99% uptime.

Major news for Ethereum developers. The Pectra upgrade is here – one of the most impactful updates in Ethereum’s history. As part of the infrastructure update, we’ve also added the new Ethereum Hoodi Testnet to our RPC Gateway.
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.
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.
We’ve extended our Faucets collection to support developers using the new Ethereum Hoodi Testnet.
