Released: 4 October 2023

What’s new

We are launching a new version of Overledger smart contract Write and smart contract Read APIs. Version 3 APIs are even more robust, clear and easy to use.

How you can benefit

The two brand new APIs will allow Overledger users to invoke any write or read function on any smart contract on the chosen blockchain, providing you indicate the functions you want to call and the smart contract ID.
