SkillProof tested Claude skills

Best Claude Skills for Crypto (2026)

Most "best skills" lists are copied README summaries. This one isn't: we installed all 34 crypto skills in our catalog, ran each against a baseline and scored four criteria. 7 passed cleanly, average score 8.6/10. The one to start with: Vly Money.

Ranked by SkillProof Score · how we score

  1. 1

    Vly Money

    Builds vly.money deep links for crypto sends and X402 paywalled-content redirects -- no execution, just correct URLs.

    From our test: Fed it 'send 0.01 USDC to <Solana address> on Solana' and it produced the exact deterministic vly.money URL per its own table; fed it an invalid pair (vUSD on Solana, which the table restricts to the…

    Quicknode Skill

    Quicknode's own reference skill covering RPC, Streams, SQL Explorer, x402/MPP agent payments, CLI, MCP, and more.

    From our test: Asked it to wire up a keyless, wallet-paid x402 RPC call with no Quicknode API key. Baseline (general x402 knowledge only) got the protocol right but had to guess at Quicknode's actual gateway domain…

    Hyperliquid (ChainGPT)

    Live read-only Hyperliquid mainnet data — markets, orderbook, account state, funding — via the ChainGPT MCP server.

    From our test: Built and ran the real mcp-server over stdio against live Hyperliquid mainnet endpoints — chaingpt_hl_funding's auto-annualized BTC rate (10.95%) matched an independent manual curl-plus-arithmetic…

    Smart Contract Vulnerability Auditor

    4-phase Solidity vulnerability scan across 36 exploit classes (Solidity only).

    From our test: Ran it against a 4-function test vault seeded with 3 bugs: it caught the reentrancy in withdraw() (external call before balance update), the missing access control on setOwner(), and — only because…

  5. 5

    Dune Sim Onchain Analytics

    Dune Sim vs Dune Analytics SQL decision framework for wallet/token intelligence — guidance only, no bundled scripts.

    From our test: Correctly routes 'watch this wallet live' to Sim's realtime endpoints and 'analyze 90 days of swap volume' to Dune Analytics SQL, with an explicit fact-vs-inference caveat on wallet labels — but it's…

  6. 6

    Wallet Security Review

    Structured 8-section wallet security checklist: keys, approvals, signing, phishing, opsec, multisig, incident response.

    From our test: Fed it a MetaMask-with-photographed-seed-phrase-and-unlimited-approvals scenario and got back a structured 'Critical risk' verdict flagging the permit-signature exploit risk a generic answer missed…

    Cosmos Vulnerability Scanner

    Spawns parallel Cosmos SDK / CosmWasm scanners for chain-halt and fund-loss bugs across 54 documented patterns.

    From our test: Fed it a synthetic Cosmos rewards module with a map-iteration bug and an unvalidated msg_server payout; the skill's own pattern docs caught both plus a third bug a generic review missed…

  8. 8

    Drift Protocol SDK Guide

    Reference guide and code patterns for the Drift Protocol perp/spot/vault SDK on Solana.

    From our test: Cross-checked the documented npm packages against the live registry -- @drift-labs/sdk and @coral-xyz/anchor are real, actively-published packages (unlike a sibling skill's broken pinned version)…

    Clone Contracts

    Pulls verified Solidity source from Etherscan V2, resolves proxies, rewrites @-imports to relative paths.

    From our test: Ran the core pipeline live on synthetic Etherscan-style JSON: it correctly split a multi-file source, rewrote an `@openzeppelin/...` import to the right relative `../lib/...` path, and laid out…

    Arbitrum DApp Skill

    Exact cargo-stylus / Foundry / nitro-devnode commands for scaffolding, testing, and deploying Arbitrum Stylus + Solidity dApps.

    From our test: Every command is copy-paste exact (cargo stylus new/check/deploy/export-abi, devnode port 8547, chain-id 412346) and it proactively surfaces two non-obvious footguns a generic-knowledge baseline…

How this ranking works

Each skill gets a fresh install in Claude Code, three trigger phrasings, and the same task run with and without it. Scores: installation (5), trigger reliability (5), output vs baseline (10), documentation honesty (5) — normalized to a 10-point SkillProof Score. Full rubric on the methodology page. Queue-verdict skills sit at the bottom until testing completes.
