Why use YAD API?

Lowest transaction cost
Pissed off with high gas prices? We feel you. That’s why we developed a smart contract using the low-level programming language Yul, thus making our transactions more cost-efficient.
Low transaction cost
High transaction costs prevent users from making swaps on the Ethereum network. We have developed a smart contract written in the low-level programming language Yul, which enables lower gas costs while processing transactions.
24/7 support
Our support team is ready to answer any questions at any time. Besides, we are always happy to receive feedback from you.
While a transaction is initiated through our API, it is still the user who signs and sends it into the smart contract for making a swap. We do not have access to their private keys and, therefore, to their funds.
We pay great attention to the technological core of the product integrated within our service. Thanks to this, our uptime is above 99.99%, and response time is less than 200 ms.
