Description
Lightning-fast crypto swaps. 240+ coins, best rates, done in minutes. Chat, CLI, or web — however you prefer.
README (SKILL.md)
Crypto Swap Skill (LightningEX)
A versatile cryptocurrency swap service powered by LightningEX API with three interaction modes:
- Chat Mode: Natural language conversation for swaps and queries
- CLI Mode: Command-line interface for scripting and automation
- UI Mode: Web-based DeFi interface for visual trading
Quick Start
Chat Mode (Default)
Simply talk to perform exchanges:
Exchange & Rates:
- "Swap 100 USDT to ETH"
- "What's the exchange rate for BTC to USDT?"
- "Exchange rate for 100 USDT (TRC20) to USDT (BEP20)"
Explore:
- "Show me supported tokens"
- "List all currencies"
- "What networks does USDT support?"
Order Management:
- "Check order status I1Y0××××"
- "Monitor order I1Y0××××"
- "Where is my order?"
Cross-chain Swaps:
- "Swap USDT from Tron to BSC"
- "Bridge ETH from Ethereum to Arbitrum"
- "Convert BTC to SOL"
CLI Mode
Prerequisite: Install the CLI tool globally:
npm install -g crypto-swap
Run the CLI:
# Start interactive wizard (default)
crypto-swap
# Show all available commands
crypto-swap --help
# List supported currencies
crypto-swap currencies
# List supported currency-network pairs
crypto-swap pair-list --send USDT --receive USDT
crypto-swap pair-list --send USDT --receive USDT --send-network TRX
# Get pair info
crypto-swap pair --send USDT --receive USDT --send-network TRX --receive-network BSC
# Check exchange rate
crypto-swap rate --send USDT --receive USDT --send-network TRX --receive-network BSC --amount 100
# Check order status
crypto-swap status --id I1Y0...
# Monitor order until complete
crypto-swap monitor --id I1Y0...
UI Mode
# Launch web UI (default port 8080, auto-assign if occupied)

Usage Guidance
This package appears to implement a crypto swap CLI and web UI that talks to the LightningEX API — that is consistent with its description. However, the registry entry lacks a verified homepage/source despite README claims of a GitHub repo, and npm packages can execute arbitrary code at install time. Before installing or running this skill: 1) Verify the package on the npm registry and that the repository (github.com/yoyoemily/crypto-swap) exists and matches the published package; 2) Inspect package.json for postinstall scripts and review source (swap.js and package dependencies) locally; 3) Prefer installing in a sandbox or container (not with sudo globally) to inspect behavior; 4) When using the UI/CLI, expect network calls to api.lightningex.io — do not supply private keys or secrets to the tool; 5) If you plan to move real funds, cross-check the service reputation and endpoint TLS fingerprints, and consider using a small test transaction first.
Capability Assessment
Purpose & Capability
Name/description, required binary (crypto-swap), SKILL.md instructions, and included JS/UI files all align with a command-line + web UI crypto swap tool backed by LightningEX API. However, registry metadata shows no homepage/source while README and SKILL.md claim a GitHub repo (https://github.com/yoyoemily/crypto-swap) — this mismatch is unexpected and worth verifying.
Instruction Scope
Runtime instructions are limited to installing and running the crypto-swap binary (npm install -g crypto-swap, run crypto-swap commands, launch UI). The included front-end code only contacts api.lightningex.io for currency lists, pair info, rates, and order operations — behavior consistent with the described purpose and not asking the agent to read unrelated local files or secrets.
Install Mechanism
Install uses npm (package: crypto-swap) which is a common mechanism for CLIs but has moderate risk because npm packages can include postinstall scripts and arbitrary code. No install URL or pinned release host is provided in the registry metadata. Given the missing homepage/source in the registry, verify the npm package content and package.json (postinstall scripts, dependencies, binaries) before global installation.
Credentials
The skill declares no required environment variables, no config paths, and no credentials. The front-end makes network calls to api.lightningex.io (expected for a swap service). There are no hidden requests for unrelated secrets or access to other services in the provided files.
Persistence & Privilege
The skill is not forced-always, does not request elevated system-wide privileges in metadata, and its install is the normal global npm CLI pattern. It does not declare modifications to other skills or system agent settings in the provided materials.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install crypto-swap - After installation, invoke the skill by name or use
/crypto-swap - Provide required inputs per the skill's parameter spec and get structured output
