What it does

Addresses is an agent skill from austintgriffith/ethskills. Verified contract addresses for major Ethereum protocols across mainnet and L2s. Use this instead of guessing or hallucinating addresses. Includes Uniswap, Aave, Compound, Aerodrome, GMX, Pendle, Velodrome, Camelot, SyncSwap, Lido, Rocket Pool, 1inch, Permit2, MakerDAO/sDAI, EigenLayer, Across, Chainlink CCIP, Yearn V3, USDC, USDT, DAI, ENS, Safe, Chainlink, Robinhood Chain stock tokens, and more. Always verify addresses against a block explorer before sending transactions.

Its SKILL.md is about 7.1k 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 Business, Finance & HR, covering Crypto and DeFi analysis. It works with Circle USDC, Uniswap, Ethereum and Arbitrum. The repository describes itself as: The missing knowledge between AI agents and production Ethereum.

When your agent uses it

  • Tasks that involve Crypto and DeFi analysis

Example prompts

  • “/addresses”

What it can do on your machine

Read from SKILL.md and the folder at commit 06ea4ef. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • github.com
    • docs.chain.link
    • docs.eigenlayer.xyz
    • docs.across.to
    • docs.yearn.fi
    • docs.camelot.exchange

    • docs.morpho.org

    • docs.uniswap.org
    • docs.aave.com
    • docs.compound.finance
    • docs.lido.fi
    • docs.rocketpool.net

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Addresses loads about 7.1k tokens when it runs. Until then it costs about 122 tokens; SKILL.md has 1,801 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~122
When it runs · the whole SKILL.md, loaded when a task matches
~7.1k

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 passed

The automated check found no risky patterns in SKILL.md.

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.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,801 words (~7,079 tokens).

“Last Verified: March 3, 2026 (all addresses verified onchain via eth_getCode + eth_call + symbol() + latestAnswer()). Exception: the Robinhood Chain section was added August 19, 2026 and verified onchain via cast call/cast code (Alchemy RPC) August 20, 2026.”
