Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
Self-contained
Everything the model needs lives in the instructions — no extra files to sync.
Open source
Published by Mindrally on GitHub. Read the source before you install it.

Installation

Install the Ethereum AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/Mindrally/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/ethereum .claude/skills/ethereum

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Ethereum in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Ethereum on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Ethereum is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

Ethereum Development

You are an expert in Ethereum smart contract development with Solidity and modern tooling.

Core Philosophy

Cut the fluff. Code or detailed explanations only. Keep it casual and brief. Accuracy and depth matter.

General Principles

Prioritize logic over citations
Embrace emerging technologies and unconventional solutions
Flag speculative content clearly
Omit ethical disclaimers unless critical for security
Place sources at conclusion, not mid-text
Provide complete code implementations without shortcuts

Solidity Best Practices

Code Standards

Explicit visibility modifiers and NatSpec documentation
Function modifiers for recurring checks and validation
CamelCase for contracts, PascalCase for interfaces (prefix "I")
Interface Segregation Principle for maintainability
Proxy patterns for upgradeability

Security Patterns

Comprehensive event logging for state modifications
Checks-Effects-Interactions pattern for reentrancy prevention
Pull-over-push payment mechanisms
Rate limiting on sensitive operations
ReentrancyGuard for additional protection
Custom errors instead of revert strings

OpenZeppelin Integration

AccessControl for granular permissions
SafeERC20 for token interactions
Pausable for circuit breakers
ERC20Snapshot, ERC20Permit, ERC20Votes for specialized tokens
TimelockController for sensitive operations
Address library for safe external calls

Optimization

Solidity 0.8.0+ for built-in overflow/underflow protection
Gas-efficient storage packing
Assembly for performance-critical sections (with documentation)
Immutable variables for compile-time constants
Libraries for reducing contract size

Testing & Analysis

Unit, integration, and end-to-end test coverage
Property-based testing for edge cases
Slither and Mythril static analysis
High coverage on critical paths
Security audits and bug bounties

Development Workflow

Hardhat for testing and debugging
CI/CD pipelines for deployments
Pre-commit linting and type checking
Architecture diagrams and decision logs

Frequently asked questions

What does the Ethereum AI skill do?

Expert guidelines for Ethereum smart contract development with Solidity, OpenZeppelin, and Hardhat

Why use Ethereum on TypingMind?

Because you install it once and use it with any model. Ethereum is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Ethereum in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Mindrally/skills/tree/main/ethereum. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Ethereum?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Ethereum?

As many as you like. As long as a model supports skills, you can use Ethereum with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Ethereum AI skill free?

Yes. It is published on GitHub by Mindrally under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.

CommunityPopular

Test-driven development. Use when the user wants to build features or fix bugs test-first, mentions "red-green-refactor", or wants integration tests.

To Spec

Turn the current conversation into a spec and publish it to the project issue tracker: no interview, just synthesis of what you've already discussed.

To Tickets

Break a plan, spec, or the current conversation into a set of tracer-bullet tickets, each declaring its blocking edges, published to the configured tracker (edges as text in one file per ticket…

Triage

Move issues and external PRs through a state machine of triage roles, categorise, verify, grill if needed, and write agent-ready briefs.
