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.
Weβre excited to introduce Web3 Name Service in Tatumβs 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.
Added domains: .eth, .base, .arb, .bsc, .sol

Weβve added HyperEVM support to Tatum's Blockchain Gateway! You can now start building on the HyperEVM Mainnet and Testnet via Tatumβs managed RPC gateway using familiar Ethereum JSON-RPC methods.
HyperEVM is an Ethereum-compatible Layer 2 built on the Hyperliquid ecosystem, designed for ultra-low latency, high throughput, and low-cost transactions. With full EVM compatibility, it enables developers to deploy smart contracts and dApps without changing their existing Ethereum tooling. Ideal for DeFi, NFTs, and on-chain trading applications, HyperEVM provides performance and scalability without the burden of running your own infrastructure.
Weβve added Monad support to Tatum's Blockchain Gateway! You can now start building on the Monad Testnet via Tatumβs managed RPC gateway using familiar Ethereum JSON-RPC methods.
Monad is an EVM-compatible Layer 1 engineered for parallel execution, fast finality, and minimal gas fees, while preserving full Ethereum tooling compatibility. Delivering up to 10,000 TPS, ~0.5s block times, and ~1s finality, it empowers developers to build scalable DeFi apps, NFT marketplaces, DAOs, and other high-performance dApps without the burden of running their own infrastructure.
Monad - a high-performance, EVM-compatible Layer 1 built for parallel execution, fast finality, and low-latency performance - is now supported in Tatumβs Data API.
With Monad integrated, you can build high-speed DeFi protocols, NFT marketplaces, DAOs, and real-time analytics platforms β all without running your own infrastructure. Simply query the blockchain, get clean structured data, and keep building.
