+# 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/local_env.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/local_env.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.
