# DLT Gateway

## Description

The DLT Gateway consists of a **fabricConnect.ts** TypeScript file, which contains the logic for identification management (certificates required for the MSP), connection management to the blockchain, and finally, it exposes a contract object with all the required information for interacting with the chaincode. The **fabricConnect.ts** is coded following the Fabric Gateway API recommendations from Hyperledger Fabric 2.4+. The compiled **fabricConnect.ts** logic is imported into a **dltGateway.js** file, which contains the gRPC logic for interaction with the TFS controller. Testing code for various performance tests is included inside the [/tests](./tests/) folder.

The chaincode is written in Go, providing a reference for the operations that are recorded in the blockchain. This chaincode must already be deployed in a working Hyperledger Fabric blockchain.
