Claude skills for crypto: before you install one
What's the best Claude skill for crypto?
Yes: 158 public skills from 79 GitHub repositories mention crypto. The best-known ones named for it are solidity security (wshobson/agents, ★ 42k), web3 testing (wshobson/agents, ★ 42k) and offensive crypto attacks (SnailSploit/Claude-Red, ★ 9.8k). Stars belong to the whole repository, not to one skill.
How do I add solidity security to Claude?
For crypto, copy the solidity-security folder from wshobson/agents (the folder that holds SKILL.md) into ~/.claude/skills/ to use it in every Claude Code project, or into .claude/skills/ for one project. For the Claude apps, upload the zipped folder as a custom skill instead.
Skill or MCP server for crypto: which do I need?
A skill teaches Claude a way of working; an MCP server gives it new tools, like access to crypto itself. We list 422 MCP servers for crypto if you need the connection.
Are there crypto skills in other languages?
No: crypto onchain trading master is written mainly in Chinese, Japanese, Korean or Russian rather than English, though the crypto task is the same. Claude can follow it either way, but read it before you install.
What licences do these crypto skills use?
Of the 50 crypto skills listed here, 35 sit in repositories under an open licence such as MIT or Apache 2.0, and 2, such as cryptofeed and crypto ta analyzer, state no licence at all, which legally means you may not reuse them. The licence badge on each card tells you which is which.
