A honeypot contract is a malicious token or smart contract designed so that buyers can purchase it but cannot sell. The code includes hidden restrictions — blacklists, tax functions, or transfer locks — that only trigger when a non-deployer wallet tries to exit.
A governance token is a token that grants its holders the right to vote on changes to a protocol — fee parameters, treasury spending, code upgrades, or strategic decisions. Holding the token is the on-chain equivalent of owning a share of the project's decision-making.
A flash loan is an uncollateralized loan that must be borrowed and repaid within a single blockchain transaction. If the loan is not repaid by the end of the transaction, the entire transaction reverts as if nothing happened — making default impossible.
Farcaster Frames are interactive mini-applications that render inside posts on the Farcaster social network. A frame can show a user interface — buttons, inputs, images — and execute on-chain transactions (mints, swaps, votes) without the user leaving the feed.
ERC-6551 (Token-Bound Account) ERC-6551 is an Ethereum standard that gives every ERC-721 NFT its own smart contract wallet. The NFT becomes the owner of an account that can hold tokens, sign transactions, and interact with dApps — making the NFT itself a portable, on-chain identity and asset container.
ERC-4337 is the Ethereum standard that enables account abstraction without requiring changes to the base protocol. It defines how smart contract wallets can submit transactions through a new infrastructure layer — UserOperations, bundlers, EntryPoint contracts, and paymasters — rather than relying on traditional Externally Owned Accounts
A dust attack is the deliberate sending of tiny token amounts ("dust") to many wallet addresses, typically used to deanonymize users, link addresses, or trick them into interacting with malicious contracts when they try to "clean up" or move the dust.
DePIN (Decentralized Physical Infrastructure Network) DePIN refers to networks that use token incentives to coordinate real-world physical infrastructure — wireless coverage, GPU compute, data storage, sensor networks, energy, or mapping — owned and operated by distributed individuals rather than a single corporation.
A data availability (DA) layer is a blockchain or network whose primary job is to publish and prove that transaction data is available for anyone to download and verify. Rollups and other modular chains rely on a DA layer to ensure their state can be reconstructed and challenged independently.
Margin mode determines how collateral backs leveraged positions on a derivatives exchange. In cross-margin, all positions share one pool of collateral and can offset each other. In isolated margin, each position has a dedicated collateral allocation that cannot be drawn from by other positions.
Concentrated liquidity is an AMM design — pioneered by Uniswap v3 — that lets liquidity providers (LPs) deposit capital within a specific price range rather than across the full 0-to-infinity curve. Within that range, capital efficiency can be hundreds of times higher than a traditional constant-product AMM.
Cliff vesting is a token unlock schedule where the recipient receives zero tokens until a specific date (the "cliff"), after which a large initial tranche unlocks and the remainder vests gradually. It is used in most venture rounds, team allocations, and advisor grants.
Chain abstraction is a design goal where users interact with crypto applications without needing to know, or manually switch to, the specific blockchain hosting the asset or app. Wallets, intents, and middleware handle bridging, gas, and routing in the background.
BTCfi is the broad category of decentralized finance applications built directly on or around Bitcoin — including Bitcoin Layer 2s, restaking protocols, lending markets, and DEXes that use BTC (not wrapped versions on other chains) as their primary asset.
BRC-20 is an experimental token standard for issuing fungible tokens on the Bitcoin blockchain using the Ordinals protocol. It inscribes JSON-formatted text into individual satoshis to define token deployments, mints, and transfers.
A bonding curve is a mathematical formula that prices a token based on its circulating supply — the more tokens minted, the higher the price; the more burned/redeemed, the lower. The curve is enforced by a smart contract that acts as a permanent automated market maker against a reserve asset.
Blob space refers to the temporary data storage area introduced to Ethereum by EIP-4844 (proto-danksharding), where rollups post compressed transaction data ("blobs") that are available for about 18 days and then pruned. It is a separate fee market from regular gas.
A basis trade is a market-neutral strategy that profits from the price difference (the "basis") between a spot asset and its futures contract, or between two derivatives on the same asset. The trader holds offsetting positions so directional price moves largely cancel out.
An atomic swap is a smart-contract-based trade in which two parties exchange tokens across different chains (or within the same chain) with a guarantee that either both legs execute or neither does. No custodian, escrow, or centralized exchange sits in the middle.
A crypto AI agent is an autonomous software program that uses large language models or other AI systems to make decisions on-chain — holding a wallet, executing trades, posting to social platforms, or interacting with smart contracts without a human pressing the button for every action.
