txnBot

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

Environments

The bot supports four environments shared across the stack:

  • BASE_SEPOLIA_LOCAL_FORK – Anvil fork of Base Sepolia started by scripts/dev.sh
  • BASE_MAINNET_LOCAL_FORK – Anvil fork of Base mainnet 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.
