Firstly, Harmony features 2-second transaction finality and 100 times lower fees than Ethereum. Furthermore, Harmony includes a highly secure random state sharding mechanism and offers cross-chain asset transfers from Ethereum, Binance, and other blockchains.
The Harmony DeFi ecosystem is now accessible to developers of all skill levels; as Tatum’s unified API allows them to leverage its powerful functionality without coding for the blockchain itself.
Tatum + Harmony
“So let’s get straight to it. Tatum’s API consolidates otherwise complex blockchain operations into single API calls that can be seamlessly integrated into your backend code. You don’t have to log in any time learning a new language or figuring out an entirely new environment, you can do everything in whatever programming language you’re already working in. If you’re already a blockchain veteran and want to code directly for Harmony nodes, you can do that too. Tatum brings the best of both worlds for all levels of developers.”
