Cross-Chain Bridge Monitor
Overview
Monitor cross-chain bridge activity across multiple protocols. Track TVL, compare fees and transfer times, and monitor transaction status for bridges like Stargate, Across, Wormhole, and LayerZero.
Prerequisites
Before using this skill, ensure you have:
- Python 3.8+ with
requests library
- Internet access for DefiLlama and bridge APIs
- Optional: Custom RPC URLs for on-chain verification
Commands
tvl - Bridge TVL Rankings
python bridge_monitor.py tvl --limit 20
Shows bridges ranked by Total Value Locked.
bridges - List All Bridges
python bridge_monitor.py bridges
python bridge_monitor.py bridges --chain arbitrum
Lists bridges by 24h volume with optional chain filter.
detail - Bridge Details
python bridge_monitor.py detail --bridge stargate
Shows detailed info including volume, chains, and TVL breakdown.
compare - Compare Routes
python bridge_monitor.py compare --source ethereum --dest arbitrum --amount 1000 --token USDC # 1000: 1 second in ms
Compares fees and transfer times across bridges for a route.
tx - Track Transaction
python bridge_monitor.py tx --tx-hash 0x...
python bridge_monitor.py tx --tx-hash 0x... --bridge wormhole
Tracks bridge transaction status across protocols.
chains - List Chains
python bridge_monitor.py chains
Shows all supported chains.
protocols - List Protocols
python bridge_monitor.py protocols
Shows supported bridge protocols with their chains.
Instructions
- Check bridge TVL rankings:
cd ${CLAUDE_SKILL_DIR}/scripts
python bridge_monitor.py tvl
- Compare bridge routes before transferring:
python bridge_monitor.py compare -s ethereum -d base -a 5000 -t USDC # 5000: bridge transfer amount in USD
- Get bridge details for research:
python bridge_monitor.py detail --bridge across
- Track a transaction:
python bridge_monitor.py tx --tx-hash 0x1234...
- Export to JSON for analysis:
python bridge_monitor.py -f json bridges > bridges.json

How It Works
The bridge monitor agent automatically activates when you discuss:
- Cross-chain bridges and transfers
- Bridge security and TVL
- Transaction status lookups
- Bridge fee comparisons
- Exploit detection and monitoring
