Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00019 | $0.02288 |
| Opus 5.5 | $0.00008 | $0.00915 |
| Sonnet 5.5 | $0.00004 | $0.00458 |
| Haiku 4.5 | $0.00002 | $0.00229 |
Grade A, and why
evm scanned grade A with 1 finding 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 1mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
(urllib, json, argparse, threading). This is a copy
100% identical to evm — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 212 lines — stays where its author put it; the contents beside it link to each section on GitHub.
EVM Blockchain Skill
Query EVM-compatible blockchain data across 8 chains with USD pricing. 14 commands: wallet portfolio, token info, transactions, activity, gas tracker, network stats, price lookup, multi-chain scan, whale detection, ENS resolution, allowance checker, contract inspector, and transaction decoder.
Supports 8 chains: Ethereum, BNB Chain (BSC), Base, Arbitrum One, Polygon, Optimism, Avalanche (C-Chain), zkSync Era.
No API key needed. Zero external dependencies — Python standard library only (urllib, json, argparse, threading).
Supersedes the standalone
baseskill. Base-specific tokens (AERO, DEGEN, TOSHI, BRETT, WELL, cbETH, cbBTC, wstETH, rETH) and all Base RPC functionality previously living underoptional-skills/blockchain/base/have been folded into this skill. Pass--chain baseto any command for Base coverage.
When to Use
- User asks for a wallet balance or portfolio on any EVM chain
- User wants to check the same wallet across ALL chains at once
- User wants to inspect a transaction by hash (or decode what it did)
- User wants ERC-20 token metadata, price, supply, or market cap
- User wants recent transaction history for an address
- User wants current gas prices or to compare fees across chains
- User wants to find large whale transfers in recent blocks
- User asks to resolve an ENS name (vitalik.eth) or reverse-lookup an address
- User wants to check if a contract has dangerous token approvals
- User wants to inspect a smart contract (proxy? ERC-20? ERC-721? bytecode size?)
- User wants to compare gas costs across chains before a transaction
Prerequisites
Python 3.8+ standard library only. No pip installs required. Pricing: CoinGecko free API (rate-limited, ~10-30 req/min). ENS: ensideas.com public API. Tx decoding: 4byte.directory public API.
Override RPC endpoint: export EVM_RPC_URL=https://your-rpc.com
Helper script path: ~/.hermes/skills/blockchain/evm/scripts/evm_client.py
Quick Reference
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

evm is a skill published in the GitHub repository nobodyohm-web/Thot (0 stars, last pushed 1mo ago), licensed MIT. It adds 19 tokens to every session and 2,288 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). It is 100% identical to evm, differing in 0 lines, and is treated as a copy.
