CrossChainKeyValue

📖 Description

The CrossChainKeyValue project is a smart contract that facilitates key/value data exchange between different blockchains using the IBC (Inter-Blockchain Communication) protocol.

🚀 Functionalities

This project provides two main functionalities:

1. Read Value

• Sends a request to another blockchain to read the value associated with a specific key.

2. Store Key-Value Pair

• Stores a key-value pair on the target blockchain.

🎯 Objective

The objective of this project is to create a simple application that demonstrates cross-chain communication using IBC. The application sends a key to a destination blockchain and receives the associated value in return.

🛠️ How It Works

1. Sending the Key:

   • The contract sends a message containing the key to the destination blockchain for either reading or writing a value.

2. Receiving the Response:

   • The destination blockchain responds with the value associated with the key or confirms the storage of the key-value pair.

🔗 Encoding with ethabi

For encoding and decoding the data, we utilize the ethabi library. The data is organized in 32-byte blocks, following the Ethereum ABI standard. Below is the structure for both operations:
