Glossary
Definitions and terms explained.
Contract
A contract is written in Solidity, a programming language specifically designed for the Ethereum platform, and defines the rules, conditions, and logic of a trade. Typically referred to as the CA, the Contract Address.
Open Method
The "open trade" method in Solidity refers to a function in a smart contract that is used to initiate a trade or transaction in a decentralized exchange built on the Ethereum network.
Tax
Taxes are fees charged by protocols for using their services and can impact the final price of a trade. Normally there are buy and sell taxes, and even sometimes a transfer tax.
Max txn
Max txn is short for max transaction amount, which is set by a contract to limit the amount spent for each transaction. It is used to make sure wallets do not buy up to much of a supply early.
Max wallet
Max wallet refers to the maximum amount of funds or tokens a trader is able to swap whilst sending a transaction across the blockchain. It is set by the contract creator within the contract deployed for a particular token.
Hidden mint
Hidden mint functions can be used for malicious purposes, such as to scam traders by hiding a function with in the code that will still enable a developer to perform a rug pull, even if liquidity is locked or the contract is renounced.
Checksum
Slippage
Fast-moving and highly liquid nature of decentralized exchanges can amplify the effects of slippage. Slippage can occur when a trade is executed and the presence of taxes can cause the final price to be higher than the initially quoted price, resulting in slippage.
Sniping
Sniping refers to a trading strategy in which a trader quickly executes a trade at a specific price in order to take advantage of a perceived market inefficiency or price discrepancy. The goal of sniping is to buy low or sell high, and to make a profit in a short period of time.
Rug
A "rug" is a term used to describe an unethical practice where a scammer tricks investors into putting money into a certain asset or pool, only to immediately remove the liquidity and run off with the funds.
The term "rug pull" is used to describe the act of the scammer withdrawing the liquidity, causing the asset price to drop suddenly and leaving investors with worthless tokens.
This practice is referred to as a "rug pull" because it is similar to pulling a rug out from under someone.
Tax farm
A "tax farm" is a strategy that involves providing liquidity to a certain asset in exchange for a portion of the trading fees generated from that asset.
Participants in a tax farm earn rewards in the form of the underlying asset as well as additional tokens that are distributed as a form of "tax" on trading activity.
However in DeFi, in the niche of sniping and meme coins, a tax farm refers often to scams whereby something within the contract inhibits traders from exiting positions where the LP is still unlocked, so a Developer can run away with the funds, as outlined in the rug explanation, as well as keeping all the tax accumulated.
