MegaNode Skills

A collection of AI agent skills for blockchain development powered by NodeReal MegaNode.

Introduction

MegaNode Skills helps AI agents (like Claude Code) understand and use NodeReal's MegaNode blockchain infrastructure APIs effectively. It provides structured knowledge about RPC endpoints, Enhanced APIs, gasless transactions, MEV protection, and more across 25+ supported blockchains.

What are Skills?

Skills are structured knowledge files that enhance AI coding agents with domain-specific expertise. They follow the Agent Skills open standard — a portable format that works across different AI tools. When you install a skill, the AI agent gains deep understanding of specific APIs, tools, and best practices without needing to search external documentation.

Available Skills

Skill	Description
meganode-skill	NodeReal MegaNode blockchain infrastructure — RPC (25+ chains), Enhanced APIs, MegaFuel, Direct Route, Debug/Trace, Marketplace, and more

Installation

Quick Install (Recommended)

npx skills add node-real/nodereal-skills

Install globally (available across all projects):

npx skills add node-real/nodereal-skills -g

Manual Install

Personal skill (available across all projects):

git clone git@github.com:node-real/nodereal-skills.git
cp -r nodereal-skills/skills/* ~/.claude/skills/

Project skill (current project only):

git clone git@github.com:node-real/nodereal-skills.git
cp -r nodereal-skills/skills/* .claude/skills/

Local Testing

git clone git@github.com:node-real/nodereal-skills.git
claude --plugin-dir ./nodereal-skills

Usage

Once installed, just ask natural language questions. The skill activates automatically based on context:

"Get the ERC-20 token balance of 0x... on BSC mainnet"
"What NFTs does this wallet hold?"
"Get the verified contract source code for 0x... on BSC"
"Set up a MegaFuel gasless transaction sponsor policy"
"Trace this transaction to debug the revert"
"Monitor new blocks on Ethereum via WebSocket"
"Get the Klaytn account info for 0x... using klay_getAccount"
"How many compute units does eth_call cost?"

MegaNode Integration

RPC Endpoints

import { ethers } from "ethers";

const provider = new ethers.JsonRpcProvider(
  `https://bsc-mainnet.nodereal.io/v1/${process.env.NODEREAL_API_KEY}`
);

Enhanced APIs (Token & NFT Data)

// Get all ERC-20 tokens held by a wallet
const response = await fetch(RPC_URL, {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    jsonrpc: "2.0", id: 1,
    method: "nr_getTokenHoldings",
    params: ["0xWalletAddress", "0x1", "0x64"],
  }),
});

Smart Contract Source Code

curl "https://open-platform.nodereal.io/${NODEREAL_API_KEY}/bsc-mainnet/contract/?action=getsourcecode&address=0xContractAddress"
