deploy

deploy is a skill for Claude Code from ChainGPT-org/chaingpt-claude-skill. It costs 127 tokens per session (1,371 once invoked), scanned A, original, MIT.

A custody-free workflow for deploying Solidity smart contracts to Ethereum-compatible networks. Solidity is a programming language for blockchain contracts, and deployment publishes a contract so it can run on a chosen blockchain.

In plain words
What is it for?
Use it to generate or audit a contract, compile it, estimate deployment cost, prepare an unsigned deployment transaction, and verify the published source on Etherscan.
Why use it?
It organizes generation, security review, compilation, cost estimation, transaction preparation, signing, and source verification into one process. The user's wallet signs and broadcasts the transaction; the workflow does not handle private keys.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

deploy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ChainGPT Deploy Skill

You orchestrate Solidity-contract deployment to real mainnet chains through the ChainGPT plugin. This skill is mainnet-first by design — testnet is an opt-in via the network parameter, never the default behavior.

The plugin is custody-free: it builds an unsigned transaction object and returns it. The user signs and broadcasts via their own wallet (MetaMask, Rabby, hardware wallet, ERC-4337 smart account, WalletConnect). Never ask the user for a private key. Never accept one in a tool argument.

The mandatory pipeline

       ▼

       │
       ▼

       │
       ▼
[user signs externally + broadcasts]

       │
       ▼
chaingpt_deploy_verify_status    ← poll until ✓ Pass — Verified

Hard rules for mainnet

  1. Never call chaingpt_deploy_build_tx with a mainnet network and acknowledgeMainnet=true until you have surfaced the audit report to the user. If the audit raised any high-severity finding, refuse to proceed until the user explicitly waives it.
  2. Always surface the estimated cost in USD before the build-tx step. Pull from chaingpt_deploy_estimate and convert via the current native-coin price.
  3. Echo the constructor args back to the user in plain English before the build-tx step. ("You're about to deploy MyToken with name='X', symbol='Y', initialSupply=1,000,000 * 10**18 to mainnet Ethereum. Confirm?")
  4. Echo the deployer address back and remind the user it must be the wallet they control.
  5. Default to testnet only when the user explicitly says "test", "testnet", "dry run", or names a testnet chain (sepolia, base-sepolia, etc.). Anything else is mainnet.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

deploy is a skill published in the GitHub repository ChainGPT-org/chaingpt-claude-skill (16 stars, last pushed 6d ago), licensed MIT. It adds 127 tokens to every session and 1,371 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
