What it does
Solidity Development is an agent skill from hiromaily/go-crypto-wallet. Solidity smart contract development workflow. Use when modifying smart contracts in apps/eth-contracts/contracts/.
Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Backend & APIs, covering Smart contracts. It works with Solidity and Ethereum. The repository describes itself as: Cryptocurrency wallet for trading for Bitcoin, Bitcoin cash, Ethereum, ERC20, XRP Leger (Ripple). The licence is MIT.
When your agent uses it
- Modifying smart contracts in apps/eth-contracts/contracts/
- Tasks that involve Smart contracts
Example prompts
- “/solidity-development”
Requirements
- A credential in PRIVATE_KEY
What it can do on your machine
Read from SKILL.md and the folder at commit 798ab10. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
bunmake
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
PRIVATE_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Solidity Development loads about 826 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 247 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:83
- [ ] `.env` added to `.gitignore`
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Solidity Development Workflow
Workflow for Solidity smart contract changes in the apps/eth-contracts/ Foundry project.
Prerequisites
Use git-workflow Skill for branch management, commit conventions, and PR creation.
Applicable Directories
| Path | Description |
|---|---|
apps/eth-contracts/contracts/ | Smart contract source files |
apps/eth-contracts/script/ | Foundry deployment scripts |
apps/eth-contracts/test/ | Foundry test files (*.t.sol) |
Toolchain
| Tool | Version | Role |
|---|---|---|
Foundry (forge) | 1.6.0-nightly | Compile, test, deploy |
| Solidity | ^0.8.34 | Smart contract language |
| OpenZeppelin Contracts | ^5.6.1 | ERC-20 / standard base contracts |
| bun | primary | npm package manager |
| solhint | ^6.0.3 | Solidity linter |
| dprint | ^0.52.0 | JS/TS formatter |
Note:
forgeis installed at~/.foundry/bin/forge(may not be in PATH). Run with full path or add~/.foundry/bintoPATH.
Setup (first time)
cd apps/eth-contracts
# 1. Install forge-std (Foundry testing/scripting library)
forge install foundry-rs/forge-std
# 2. Install npm dependencies (@openzeppelin/contracts, solhint, dprint)
bun installVerification Commands
cd apps/eth-contracts
forge build # Compile all contracts (artifacts → out/)
forge test -v # Run Foundry unit tests
bun run lint # Solidity lint via solhint (must exit 0, zero errors)
bun run fmt # Format JS/TS files via dprint (must exit 0)Deployment (local)
cd apps/eth-contracts
export PRIVATE_KEY=0x<deployer-private-key>
forge script script/DeployHYC.s.sol --rpc-url http://localhost:8545 --broadcast
# → outputs contract address, tx hash, gas usageCompatible with both anvil and geth nodes at http://localhost:8545.
Self-Review Checklist
Code Quality
- Named imports used (
import {Foo} from "...") — no global imports - NatSpec tags present (
@title,@author,@notice,@param) on contracts and public functions - Explicit visibility on all functions (constructors exempt in Solidity ≥0.8)
- Gas optimization considered
- Events emitted for state changes
Security
- No reentrancy vulnerabilities
- No hardcoded private keys or sensitive values — use env vars
-
.envadded to.gitignore - Access control properly implemented
- Integer overflow protection (Solidity ≥0.8 has built-in checks)
Testing
- Foundry test file (
test/*.t.sol) covers all acceptance criteria -
forge testpasses with zero failures -
bun run lintexits 0 with zero solhint errors
ABI / Go Bindings
After contract changes, if Go bindings are needed:
# 1. Compile
cd apps/eth-contracts
forge build
# 2. Regenerate Go bindings (if target ABI changed)
make gen-abiRelated Chain Context
- ETH (Ethereum)
- ERC-20 token standard
- Local nodes:

Can I use Solidity Development in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add hiromaily/go-crypto-wallet --skill solidity-development -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/solidity-development, .gemini/skills/solidity-development, .github/skills/solidity-development and .opencode/skills/solidity-development in your project.
What does Solidity Development need to run?
Going by SKILL.md and its folder, Solidity Development needs the command-line tools its instructions call (bun and make) and credentials named PRIVATE_KEY. Our summary lists: A credential in PRIVATE_KEY.
Does Solidity Development access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Solidity Development safe to install?
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
What licence does Solidity Development use?
Solidity Development is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Solidity Development use?
About 826 tokens (SKILL.md is roughly 3.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Solidity Development?
Skills that share tags, products or a category with Solidity Development: Developing Smart Contracts (LFDT-Lineth/lineth-monorepo, 126 stars), Ethskills (austintgriffith/ethskills, 295 stars), Smart Contract Development (vechain/x-app-template, 450 stars) and Smart Contract Interaction (Nethereum/Nethereum, 2.3k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Solidity Development?
