Antenna SDK Overview

"Antenna" is the IoTeX native SDK, allowing you to directly interact with a local or remote IoTeX node using a gRPC connection, and is available for the most popular programming languages. The difference between developing using Antenna or Web3 SDK is that Antenna wraps the full gRPC Native API of the IoTeX protocol and uses the native representation of IoTeX addresses.

While IoTeX fully supports the Ethereum API, allowing you to use Web3 tools for dApp development, the fact that IoTeX architecture is more complex than Ethereum's, makes Antenna the necessary choice when you want to make use of IoTeX unique features. For example, "Delegates," "Block Producers," "Staking Transactions," "Buckets," "Voting," etc., are concepts that find no correspondence in Ethereum. Therefore if you want to use these features in your dApp, you won't find them in, e.g., Web3js: in this case, you will have to use Antenna.

The Example code section includes examples for each supported language.
