Celestia Transfer

A TypeScript-based tool for interacting with the Celestia blockchain using the CosmJS library.

Logic

Reads mnemonic phrases from a data/mnemonic.txt;
Waits for a specified genesis timestamp before proceeding;
Waits the positive balances of wallets;
Sends transactions from donors to recipients;
Prints the new balances of wallets again.

Feature: Batch Transactions

This script is capable of bundling multiple messages into a single transaction, allowing you to send tokens from one wallet to multiple different wallets in one action.

To utilize this feature, simply create a new line in data/mnemonic.txt with the same sender (donor mnemonic), but a new recipient and a new amount of tokens.

Important Note on RPC Endpoint and Explorer Path

The RPC_ENDPOINT and EXPLORER_TX_PATH values provided in the src/config.js file are set for the testnet. It's imperative that every user of this script specifies their own values for these configurations.

RPC Endpoint: If everyone uses the same RPC endpoint, it will likely become overloaded and fail, resulting in unsuccessful transactions. Moreover, as of now, there are no publicly available mainnet RPC endpoints since the mainnet has not been launched yet. The functionality of this script heavily relies on the RPC endpoint, hence ensure to provide a reliable and unique endpoint for your use.
Explorer Transaction Path: Similar to the RPC endpoint, ensure to set the EXPLORER_TX_PATH to a suitable value based on your network (testnet/mainnet).

Please treat these configurations with utmost attention to ensure the proper functionality of the script.

Installation

Ensure you have Node.js v20.5.1 or newer installed on your machine, then follow these steps:

Clone the repository:

git clone https://github.com/cyberomanov/celestia-transfer.git
cd celestia-transfer/

Install the dependencies (@cosmjs/proto-signing: ^0.31.1, @cosmjs/stargate: ^0.31.1):
```
npm install
```
Install TypeScript globally (if you haven't already):
```
npm install -g typescript
```
Prepare your data/mnemonic.txt file with the mnemonic phrases, recipients and amount to transfer (you can use the same mnemonic with several unique recipients).

A memo is required for depositing funds on certain centralized exchanges. However, if you don't wish to specify a memo, ensure that the string ends with amount_to_transfer.
```
word1 word2 ... word12##celestia_recipient1##amount_to_transfer1##memo1
word1 word2 ... word12##celestia_recipient2##amount_to_transfer2
word13 word14 ... word24##celestia_recipient3##amount_to_transfer3
word25 word26 ... word36##celestia_recipient4##amount_to_transfer4##memo2
```

Update the src/config.js file to set the RPC endpoint, gas multiplier, and other settings (carefully change the url from testnet to mainnet):

export const RPC_ENDPOINT = "https://celestia-testnet-rpc.polkachu.com"
export const GAS_MULTIPLIER = 1.5
export const EXPLORER_TX_PATH = "https://celestia.explorers.guru/transaction"

export const GENESIS_TIMESTAMP = 1698764400000
export const DEFAULT_ADDRESS_PREFIX = "celestia"
export const DEFAULT_TOKEN_PREFIX = "utia"
export const DEFAULT_DENOMINATION = 1_000_000

Compile TypeScript to JavaScript:
```
tsc
```

Run the generated JavaScript file:

node build/index.js
