What it does

Monitoring Cross Chain Bridges is an agent skill from jeremylongshore/tons-of-skills-marketplace. Monitor cross-chain bridge TVL, volume, fees, and transaction status across networks. Use when researching bridges, comparing routes, or tracking bridge transactions. Trigger with phrases like "monitor bridges", "compare bridge fees", "track bridge tx", "bridge TVL", or "cross-chain transfer status".

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 15 other files, including scripts and reference files (for example `ARD.md`, `PRD.md` and `config/settings.yaml`). Compatibility notes: Designed for Claude Code

The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Researching bridges
  • Comparing routes
  • Tracking bridge transactions
  • With phrases like monitor bridges

Example prompts

  • “monitor bridges”
  • “compare bridge fees”
  • “track bridge tx”
  • “/monitoring-cross-chain-bridges”

Requirements

  • Python 3
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Grep, Glob, Bash(python:*bridge_monitor*)

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Check bridge TVL rankings
  2. Compare bridge routes before transferring
  3. Get bridge details for research
  4. Track a transaction
  5. Export to JSON for analysis

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Grep
    • Glob
    • Bash(python:*bridge_monitor*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 6 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • defillama.com
    • wormholescan.io
    • layerzeroscan.com
    • across.to

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Monitoring Cross Chain Bridges loads about 1.1k tokens when it runs, and up to ~4.3k if it reads all its reference files. Until then it costs about 83 tokens; SKILL.md has 298 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~83
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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
bash
python bridge_monitor.py tvl --limit 20

Shows bridges ranked by Total Value Locked.

bridges - List All Bridges
bash
python bridge_monitor.py bridges
python bridge_monitor.py bridges --chain arbitrum

Lists bridges by 24h volume with optional chain filter.

detail - Bridge Details
bash
python bridge_monitor.py detail --bridge stargate

Shows detailed info including volume, chains, and TVL breakdown.

compare - Compare Routes
bash
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
bash
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
bash
python bridge_monitor.py chains

Shows all supported chains.

protocols - List Protocols
bash
python bridge_monitor.py protocols

Shows supported bridge protocols with their chains.

Instructions

  1. Check bridge TVL rankings:

    bash
    cd ${CLAUDE_SKILL_DIR}/scripts
python bridge_monitor.py tvl

  2. Compare bridge routes before transferring:

    bash
    python bridge_monitor.py compare -s ethereum -d base -a 5000 -t USDC  # 5000: bridge transfer amount in USD

  3. Get bridge details for research:

    bash
    python bridge_monitor.py detail --bridge across

  4. Track a transaction:

    bash
    python bridge_monitor.py tx --tx-hash 0x1234...

  5. Export to JSON for analysis:

    bash
    python bridge_monitor.py -f json bridges > bridges.json

Supported Bridges

BridgeTypeAvg TimeTypical Fee
WormholeMessaging~15 min~0.1%
LayerZeroMessaging~3 min~0.06%
StargateLiquidity~2 min~0.06%
AcrossLiquidity~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
