What is smart-contract?

A read-only tool for inspecting Ethereum smart contracts and calling their view or pure methods without changing blockchain state.

Use it to read ERC-20 token details, balances, and allowances; inspect ERC-721 ownership and metadata; read storage; decode events; and retrieve contract code.

It provides contract and token information without sending transactions or modifying data.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00014	$0.00278
Opus 5.5	$0.00006	$0.00111
Sonnet 5.5	$0.00003	$0.00056
Haiku 4.5	$0.00001	$0.00028

Security

Grade A, and why

smart-contract 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 2mo 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.

What it actually says

Smart Contract Skill

Provides read-only smart contract interaction capabilities:

Read ERC20 token info (name, symbol, decimals, total supply)
Check ERC20 token balance for an address
Check ERC20 allowance for spender
Read contract storage slots
Decode contract events/logs
Get contract code

Use builtin_smart_contract tool with fields:

operation: one of "erc20_info", "erc20_balance", "erc20_allowance", "erc721_owner", "erc721_metadata", "code", "storage"
contract_address: Ethereum contract address
address: (optional) wallet address for balance/allowance queries
spender: (optional) spender address for allowance query
token_id: (optional) NFT token ID for ERC721 queries
network: (optional) Ethereum network: "mainnet", "sepolia", "holesky" (default: "mainnet")

Note: Only read-only (view/pure) contract calls are supported. No state-changing transactions.

Changes

What this file has done since we first saw it

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.
