# Terminology

* **WISE** — the token and contract described herein.
* **YODA** — the base unit of the WISE token, analogous to wei for ETH, or satoshi for BTC.  One WISE equals one quintillion YODA (1,000,000,000,000,000,000).
* **Stake** — a time locked deposit of WISE which earns interest over time.
* **Liquidity Transformer Epoch** — the first fifty days of the contract's existence, during which users may deposit ETH to reserve part of the initial supply of WISE.
* **Circulation Epoch** — the epoch immediately following the end of the LT Epoch, during which users may mint their tokens reserved in the LT Epoch, transfer tokens, stake tokens, etc.
* **Uniswap** — a decentralized, non-custodial ERC-20 token and ETH exchange on the Ethereum blockchain.  The WISE contract is integrated directly with Uniswap.  General info on Uniswap is [here](https://uniswap.org/), Uniswap exchange stats are [here](https://uniswap.info/), and the main exchange is [here](https://app.uniswap.org/).
* **ERC-20** — a standard interface for Ethereum smart contract tokens.  ERC stands for “Ethereum Request for Comment”.  The original EIP (Ethereum Improvement Proposal) describing ERC-20 tokens can be found [here](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-20.md).
