Predictive Web3 wallet and contract risk scoring across 8 blockchains via a single MCP endpoint.

Try itScores a crypto wallet's on-chain activity across Ethereum, Arbitrum, Base, Optimism, and Polygon against common retroactive airdrop farming heuristics (transaction count, multi-chain diversity, wallet balance, account activity) using free public JSON-RPC endpoints with no API key required. Useful for crypto airdrop farming, defi power users, whale-style multi-wallet trackers, passive income seekers, python developers, and ai agent operators who want a quick 0-100 eligibility health-check before a snapshot. Supports scoring a single wallet or comparing several wallets side by side to see which ones have the strongest multi-chain footprint. Built from the generic criteria protocols like Arbitrum, Optimism, zkSync, and Blast have historically leaned on — cross-chain tx volume, distinct chain presence, and account age/balance — not any single project's unpublished real snapshot rules.

The skill document
Airdrop Eligibility Tracker
Pulls transaction count, native balance, and contract-deployment status for a wallet across five EVM chains (Ethereum, Arbitrum, Base, Optimism, Polygon) via free public RPC endpoints, then produces a 0-100 heuristic "airdrop farming health" score plus a plain-language tier.
When to use this skill
- The user wants to check whether a wallet "looks active enough" for retroactive airdrop snapshots before an announcement.
- The user is running multiple farming wallets and wants to compare them side by side to find weak ones that need more activity.
- The user asks "how is my airdrop farming going" or "which of my wallets has the best multi-chain footprint."
How to run it
python3 scripts/airdrop_tracker.py score 0xYourAddress
python3 scripts/airdrop_tracker.py score 0xYourAddress --json
python3 scripts/airdrop_tracker.py score 0xYourAddress --chains ethereum,arbitrum,base
python3 scripts/airdrop_tracker.py compare 0xAddr1 0xAddr2 0xAddr3
Scoring model (0-100)
- Tx volume (0-40 pts): total transaction count summed across scanned chains, capped at 200 total tx.
- Chain diversity (0-35 pts): number of chains with at least one transaction, weighted heavily because most L2 airdrops (ARB, OP) have historically rewarded cross-chain / bridge activity specifically.
- Balance signal (0-25 pts): flat bonus if any scanned chain holds more than 0.01 of its native token, as a rough sybil-vs-real-user signal.
Tiers: STRONG (75+), MODERATE (45-74), WEAK (15-44), DORMANT (<15).
Important limitation — read this before trusting the score
This tool has no knowledge of any specific project's actual, often unpublished, snapshot criteria. Real airdrops frequently filter on things this script cannot see: Discord/Twitter engagement, governance votes, specific protocol interactions (e.g. "used Uniswap 5+ times"), Sybil clustering analysis, or a hard minimum spend threshold. Treat the score as a rough directional health-check ("is this wallet obviously dormant or obviously active"), never as a guarantee of eligibility for any real airdrop.
Requirements
- Python 3.8+, standard library only.
- Outbound HTTPS access to
*.publicnode.comRPC endpoints (free, no key).

Screens Ethereum and other EVM wallet addresses (Base, Polygon, BSC, Arbitrum, etc.) against the ScamSniffer community-maintained blocklist of known phishing, wallet drainer, and scam addresses, with no API key required. Use this when the user asks to check if a crypto address is a scam, verify a wallet before sending funds or signing a transaction, screen for wallet drainer addresses, check if an address is blacklisted or flagged for phishing, do a quick on-chain safety check before an airdrop claim or NFT mint, or wants a fast keyless scam address lookup tool. Pulls a public, actively updated JSON feed (~2,500+ known bad addresses) and caches it locally for 6 hours. Complements, but does not replace, deeper on-chain forensics or paid threat-intel services — a clean result means the address is not on this particular list, not that it is verified safe.
