Recently Defined
DePIN
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.
Deposit / Withdrawal
Deposit = adding funds/assets to your exchange account; Withdrawal = sending them out to external wallet or bank.
Deposit Address
A unique wallet address (string of letters/numbers) generated by the CEX for receiving crypto from external wallets.
DEX Aggregator
A DEX aggregator is a protocol or service that sources liquidity from multiple decentralized exchanges and routes a user’s trade across the best available pools or paths to achieve optimal price and minimal slippage.
Diversification
Diversification means spreading investments across multiple assets to reduce risk.
Dollar Cost Averaging
Dollar-cost averaging (DCA) is an investment strategy where fixed amounts are invested at regular intervals regardless of price.
Double Spending
Double spending is an attempt to spend the same cryptocurrency more than once.
Dust Attack
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.
DYOR
DYOR means Do Your Own Research. It is a reminder that every trader and investor should investigate a project, market, or trade idea independently before committing capital.
ERC-4337
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
ERC-6551
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.
EVM (Ethereum Virtual Machine)
The Ethereum Virtual Machine (EVM) is a decentralized computation engine that executes smart contracts on the Ethereum network.
EVM Compatibility
EVM compatibility means a blockchain can execute smart contracts written for the Ethereum Virtual Machine (using Solidity/Vyper) with little or no code changes, supporting the same opcodes, standards (ERC-20, etc.), and tooling.
Exchange Reserve
Exchange reserves measure how much cryptocurrency is held on centralized exchanges.
Exploit
An exploit is when someone uses a weakness in code, design, or security to gain unauthorized value.
Fakeout (False Breakout)
A fakeout is a false breakout where price briefly moves beyond a key level and then reverses.
Farcaster Frames
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.
Faucet
A faucet is a tool that gives small amounts of testnet tokens for free.
Fear and Greed Index
The Fear & Greed Index measures overall market sentiment.
Fiat Currency
Government-issued money (USD, EUR, ZAR, etc.) used for deposits, withdrawals, or trading pairs on a CEX.
