# txnBot

Automation worker that monitors staking positions and calls `recenter()` / `payTax()` when profitable.

## Environments

The bot supports three environments shared across the stack:

- `BASE_SEPOLIA_LOCAL_FORK` – Anvil fork started by `scripts/dev.sh`
- `BASE_SEPOLIA` – Public Base Sepolia testnet
- `BASE` – Base mainnet

Set `ENVIRONMENT` alongside the other variables listed below to target the desired chain.

## Configuration

Create an environment file (e.g. `.env`) with:

```
ENVIRONMENT=BASE_SEPOLIA
PROVIDER_URL=<rpc-url>
PRIVATE_KEY=<hex-private-key>
LM_CONTRACT_ADDRESS=<liquidity-manager-address>
STAKE_CONTRACT_ADDRESS=<stake-contract-address>
GRAPHQL_ENDPOINT=<ponder-graphql-url>
# Optional: PORT=43069
```

`scripts/dev.sh start` generates these values automatically for the local fork, writes them to a temporary file, and keeps the process running in the background.

## Local Run

```
npm install
npm start
```

The service exposes a lightweight status endpoint at `GET /status` reporting uptime, balances, and the most recent automation activity.

## Generate a New Operator Key

Run `npm run generate-key` to produce a fresh EOA. The command writes the private key and address as JSON log entries to `txnbot.log`. Be sure to rotate the log or move the credentials to a secure store immediately after use.
