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 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.

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.
