Transaction Bot - CLAUDE.md

Automated service for triggering protocol maintenance transactions.

Purpose

This bot monitors the KRAIKEN protocol and automatically:

  • Triggers liquidity position recentering when needed
  • Processes tax liquidations for defaulting positions
  • Maintains protocol health through timely interventions

Architecture

Core Components

service.js - Main bot loop

  • Queries subgraph for protocol state
  • Evaluates recentering conditions
  • Submits transactions when profitable

generateKey.js - Utility for creating bot wallets

  • Generates secure private keys
  • Provides addresses for funding

Configuration

Environment variables (.env):

PRIVATE_KEY=0x...
RPC_URL=https://...
SUBGRAPH_URL=https://...

Recentering Logic

The bot evaluates:

  1. Current price vs liquidity position centers
  2. Gas costs vs expected rewards
  3. MEV protection considerations

Triggers recentering when:

  • Price has moved significantly from position centers
  • Expected rewards exceed gas costs by threshold
  • No recent recentering has occurred

Tax Liquidation

Monitors staking positions for:

  • Tax payment defaults
  • Insufficient balances
  • Expired grace periods

Development Commands

# Install dependencies
npm install

# Generate new bot wallet
node generateKey.js

# Run the bot
node service.js

# Run with debug logging
DEBUG=* node service.js

Deployment Considerations

  • Fund bot wallet with ETH for gas
  • Set appropriate gas price limits
  • Monitor for stuck transactions
  • Implement proper error handling and retries

Security Notes

  • Private key must be kept secure
  • Use dedicated bot wallet (not personal)
  • Limit wallet balance to operational needs
  • Monitor for unusual activity

Performance Optimization

  • Cache subgraph queries
  • Batch similar operations
  • Use flashbots for MEV protection
  • Implement exponential backoff for retries
