Bridge Monitor

Monitor cross-chain bridge health, TVL, transaction status, and liquidity pools. Get alerts on bridge anomalies and stuck transactions.

Supported Protocols

Stargate — LayerZero-based cross-chain liquidity transport
Wormhole — Guardian-network message passing across EVM chains

Additional bridges (Across, Hop, and native L2 bridges like Arbitrum/Optimism/Polygon PoS) are on the roadmap. Follow our changelog for updates.

Configuration

{
  "name": "Stargate ETH → Polygon",
  "bridgeProtocol": "stargate",
  "sourceChainId": 1,
  "destChainId": 137,
  "sourceRpcUrl": "https://eth.llamarpc.com",
  "destRpcUrl": "https://polygon-rpc.com",
  "trackedAddresses": ["0x8731d54E9D02c286767d56ac03e8037C07e01e98"],
  "checkIntervalSeconds": 120,
  "stuckThresholdMinutes": 60
}

trackedAddresses are the bridge contracts or user wallets whose transactions you want to correlate across source and destination chains.

Metrics Monitored

Metric	Description	Alert

Use Cases

1. Bridge Health Monitoring

Monitor: All major bridges

Channel: Slack #bridge-alerts
Action: Notify users

2. Personal Transaction Tracking

Monitor: Your bridge txs
Alert: Pending > 1 hour
Channel: Telegram personal
