Perform Web3 operations directly from Claude Code: deploy audited smart contracts, execute DEX trades and DeFi strategies, analyze portfolios and tokens, and access on-chain data across multiple blockchains — all with custody-free, policy-gated execution.
Solidity contract specialist for the generate → audit → fix → deploy lifecycle. Use when writing, reviewing, auditing, or deploying smart contracts. Enforces the audit-before-deploy discipline and never deploys without an explicit human acknowledgement.
Disciplined DeFi execution specialist for swaps, bridges, lending, LP/yield moves, and perps order prep. Use when the user wants to actually DO something on-chain. Runs mandatory pre-flight checks, respects every custody gate, and never sets acknowledgeMainnet or signs from the agent wallet without explicit human approval in the current conversation.
Read-only Web3 research analyst. Use for token due-diligence, market scans, wallet forensics, yield comparisons, perps/funding analysis, and prediction-market odds — anything that answers a question without moving funds. It cannot build or sign transactions, so it is safe to run unattended.
ERC-4337 v0.7 account-abstraction foundation. Custody-free utilities for computing userOpHashes, packing UserOperations into the EntryPoint wire format, and proxying bundler-RPC calls (Pimlico / Alchemy / Stackup). Triggers: ERC-4337, account abstraction, smart contract wallet, userop, user operation, bundler, paymaster, session key, EntryPoint, AA wallet, smart wallet, gas sponsorship.
Give the AI agent its own EVM wallet with admin-controlled policies the agent CANNOT bypass even under prompt injection. Encrypted keystore (AES-256-GCM, scrypt KDF), policy file the agent has no tool to write, deterministic policy gate on every signing operation, optional local HTTP dashboard. Triggers: agent wallet, give the agent a wallet, agent address, fund the agent, agent autonomy, policy gate, kill switch, agent permissions, bounded autonomy, ERC-4337 alternative, session-key alternative.
Base chain ecosystem — Basenames (name.base.eth ENS-style naming) resolution + registration, and Base App / Farcaster Mini App scaffolding (manifest, embed meta tags, validation). Custody-free. Triggers: base name, basename, .base.eth, resolve base name, register basename, base app, mini app, miniapp, farcaster frame, fc:miniapp, MiniKit, OnchainKit, base super app, farcaster.json manifest.
Cross-chain bridging via the ChainGPT plugin. Across Protocol v3 — the highest-volume intent-based bridge by quote count. 10 EVM mainnets supported. Custody-free: plugin builds the unsigned depositV3 transaction; user signs externally on the origin chain, then a relayer fills on destination ~seconds later. Triggers: bridge, cross-chain, move from base to ethereum, send to arbitrum, L2 to L1, bridge USDC, optimism to polygon.
Build with the ChainGPT Web3 AI developer platform. Full API/SDK reference and project scaffolding for: Web3 AI Chatbot & LLM, AI NFT Generator, Smart Contract Generator, Smart Contract Auditor, AI Crypto News, AgenticOS Twitter agents, and Solidity LLM. Use when building blockchain apps, Web3 chatbots, NFT tools, smart contract tools, crypto news feeds, AI agents, or integrating any ChainGPT API. Triggers: chaingpt, web3 ai, nft generator, smart contract audit, crypto news api, agenticos, solidity llm, cgpt, blockchain ai, token analytics.

The agent tries to overspend; the policy gate — a file the model has no tool to write — refuses in code. Prompt injection gets a refusal, not your funds.
Three exchanges that show the whole philosophy — capability, then the guardrails that make it safe to walk away:
You: is this token safe? 0x9840...0f98
Claude: → chaingpt_risk_token + chaingpt_research_token
Verdict: no honeypot flags, ownership renounced, $952k liquidity on
PancakeSwap, top-10 holders 31%. Two informational flags: ...
You: set up a daily $100 ETH DCA that runs without me
Claude: → chaingpt_strategy_dca_plan → save_plan → /schedule cron
Done. Every morning: due_steps → fresh quote → agent wallet signs
inside policy caps → journal records the tx hash. Crashes and
double-fired schedules can't double-buy — the journal refuses.
You: (prompt injection, or just a bad idea) send 5 ETH to 0xattacker
Claude: → chaingpt_agent_wallet_sign_and_send
⛔ Policy refused this transaction.
Reason: To-address not in allowedToAddresses (5 entries).
No MCP tool can relax these rules from inside the agent.
That last refusal is the product: the policy file lives outside the model's reach, every signature is checked in code, and daily spend + tx-count velocity caps bound even fully-compliant behavior. See Security model.
