web3-glossary

web3-glossary is a skill for Claude Code, Codex from nirholas/three.ws. It costs 57 tokens per session (1,824 once invoked), scanned A, original, Apache-2.0.

A glossary that explains more than 150 Web3 and DeFi terms, including blockchain networks, financial protocols, NFTs, DAOs, and layer-2 systems. Web3 refers to internet services built around blockchains, while DeFi means financial services run by code instead of traditional institutions.

In plain words
What is it for?
It helps define terms such as airdrop, bridge, automated market maker, account abstraction, and token buyback-and-burn.
Why use it?
It removes unfamiliar crypto jargon when someone is reading documentation, news, or community discussions.

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

web3-glossary 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 yesterday.

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.

Web3 & DeFi Glossary

Quick-reference glossary for AI agents helping users navigate crypto terminology.

A

Account Abstraction (ERC-4337): Standard for smart contract wallets that enables features like gasless transactions, social recovery, and batched operations.

Airdrop: Free distribution of tokens to wallet addresses, usually to reward early users or build community.

AMM (Automated Market Maker): DEX model using liquidity pools and mathematical formulas instead of order books. Examples: Uniswap, Camelot.

APR (Annual Percentage Rate): Yearly return WITHOUT compounding.

APY (Annual Percentage Yield): Yearly return WITH compounding. Always higher than equivalent APR.

Arbitrage: Profiting from price differences between markets. Key for maintaining stablecoin pegs (e.g., USDs mint/redeem arbitrage).

Arbitrum: Ethereum Layer 2 using optimistic rollups. Largest L2 by TVL. Home of Sperax (USDs, SPA, Farms).

B

Block: A batch of transactions confirmed together. Ethereum: ~12 sec, Arbitrum: ~2 sec.

Bridge: Protocol for moving assets between blockchains. Examples: Stargate, Across, Hop.

Buyback-and-Burn: Protocol uses revenue to buy tokens on the market and permanently destroy them. Sperax uses 30% of USDs yield for SPA buyback-and-burn.

C

CDP (Collateralized Debt Position): Locking collateral to mint/borrow assets. Used by Maker (DAI) and Liquity (LUSD).

CEX (Centralized Exchange): Traditional crypto exchange (Coinbase, Binance). Custodial — they hold your keys.

Concentrated Liquidity: V3-style LP where you choose a price range. Higher capital efficiency but higher impermanent loss risk.

Composability: The ability to combine DeFi protocols like building blocks. "DeFi Legos."

D

DAO (Decentralized Autonomous Organization): Community-governed organization using smart contracts and token voting.

DCA (Dollar Cost Averaging): Investing fixed amounts at regular intervals to reduce timing risk.

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.
