Asset swapper does the following:

1. Monitor db for new swap tasks
2. Do highload swaps
3. Monitors swaps states and updates swaps states in the db

Supported assets

For now only following assets are supported:

1. TON
2. stTON
3. jUSDT
4. USDT

tsTON and jUSDC are banned, but you can easily allow them in the config.ts file.

Start and stop

The swapper service can be started by ts-node src/index.ts To stop it press Ctrl + C or send the SIGINT signal, which is monitored and processed.

Environment variables

To use this service, you should create an .env file and place it to the project root. It contains configuration and sensitive data as endpoints, keys, etc. That is why it shouldn't be stored in git repository. The .gitignore file serves this goal.

TON_RPC_ENDPOINT= #your favorite rpc endpoint

TON_RPC_TOKEN= #access token for your rpc endpoint

TELEGRAM_BOT_TOKEN= #your bot access token

SERVICE_CHAT_ID= #telegram chat id

HIGHLOAD_WALLET_ADDRESS= #your highload v2 wallet address

HIGHLOAD_WALLET_MNEMONIC= #"put your mnemonic words here"

DB_PATH=./database-mainnet.db #path to the liquidator bot db

Scripts

Scripts in the project are intended for deployment and debugging. They also can be used as examples.

balances

You can use the get_balances.ts script for fetching your highload wallet balances. To monitor them just type watch -n 2 ts-node src/scripts/get_balances.ts.

database

The add_swap_task allows adding a new task to the database usage: FROM=ton TO=usdt AMOUNT=1.234 ts-node src/scripts/database/add_swap_task.ts

The get_swaps.ts script prints all swaps descriptions - it is a helpful debugging tool.

highload

The deploy_highload_wallet script can be used for deploying a highload wallet
