n8n-nodes-chainscope

This is an n8n community node. It lets you use ChainScope in your n8n workflows.

ChainScope is a multi-chain (Ethereum, Base, Bitcoin, Solana, Arbitrum, Optimism, Polygon) wallet and transaction intelligence API — balances, transaction lookup, network fees, contract metadata, token holdings, address activity history, ENS resolution, and a flagship wallet-scan combining all of it plus OFAC sanctions screening. Paid per call in USDC on Base via x402 — no API keys, no signup.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation, or install n8n-nodes-chainscope directly from the Community Nodes tab in a self-hosted n8n instance.

Operations

  • Wallet Balance — native balance for an address on any of the 7 supported chains.
  • Transaction Lookup — status/from/to/value/fee/timestamp for a transaction hash.
  • Network Fee Estimate — current slow/standard/fast fee levels for a chain.
  • Contract Inspect — name/symbol/decimals for an ERC-20-style contract (EVM chains only).
  • Token Holdings — a wallet's token balances (watchlist on EVM chains, full enumeration on Solana).
  • Address Activity — recent transaction history for an address.
  • Wallet Scan (Flagship) — balance + holdings + activity + OFAC sanctions check in one call.
  • ENS Resolve — forward (name.eth → address) or reverse (address → name) resolution.
  • Wallet Balance Batch — up to 10 wallets across mixed chains in one call.

Credentials

You need an EVM wallet funded with a small amount of USDC on Base mainnet (a few dollars covers thousands of calls at ChainScope's per-call prices, currently $0.01–$0.04). Create a "ChainScope Wallet" credential in n8n and paste the wallet's private key — it's used locally, at execution time, to sign each payment; it is never sent to ChainScope or logged anywhere.

The credential also has a Max Payment Per Call field (default $0.25) — a local safety ceiling. The node refuses to sign a payment above this amount no matter what a response asks for, protecting the wallet against a compromised or malicious server requesting an inflated charge.

Compatibility

Tested against n8n's programmatic node API v1. Requires Node.js 20+ (same as n8n itself).

Usage

Pick a Tool from the dropdown; the relevant fields (address, chain, etc.) appear below it. Each execution pays for exactly one call — chain a Schedule Trigger node in front of this node for recurring checks (e.g. daily wallet balance monitoring).
