Cross-Chain Bridge Monitor

Name: monitoring-cross-chain-bridges
Author: jeremylongshore

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

Supported Bridges

Bridge	Type	Avg Time	Typical Fee
Wormhole	Messaging	~15 min	~0.1%
LayerZero	Messaging	~3 min	~0.06%
Stargate	Liquidity	~2 min	~0.06%
Across	Liquidity	~1 min	~0.04%

Supported Chains

Ethereum, BSC, Polygon, Arbitrum, Optimism
Base, Avalanche, Fantom, Solana (Wormhole)
45+ total chains via DefiLlama

Output

TVL rankings: Bridges sorted by locked value
Fee comparison: Side-by-side fee and time estimates
TX status: Source/destination confirmation status
JSON format: Structured data with -f json flag

Error Handling

See ${CLAUDE_SKILL_DIR}/references/errors.md for comprehensive error handling including:

API unavailability and fallback behavior
Transaction tracking edge cases
Rate limiting mitigation

Examples

See ${CLAUDE_SKILL_DIR}/references/examples.md for detailed examples including:

Finding best route for large transfers
Monitoring transactions after bridging
Research workflows for bridge safety
