# Introduction
Vexy is a purpose-built NFT exchange and marketplace aggregator created to improve the secondary market for veAERO and veVELO. It offers market insights and a single, intuitive interface for buyers and sellers to more efficiently trade these unique NFTs.
# How it works
Vexy consists of [Listings](/listings) and [Offers](/offers). In both cases, users retain custody of their NFTs and fungible tokens until a sale is consummated. Buyers and sellers simply grant allowances to the Vexy marketplace contract when creating listings and offers.
Security is ensured by only allowing a small number of whitelisted currencies and NFTs to be traded. Currently, purchases can be made using USDC, WETH, and the underlying escrowed token (AERO or VELO). We look forward to supporting additional tokens in the future as the market grows.
Prices are denominated in the token chosen by the seller and this same token must be used by the buyer. For example, a seller may choose to list veAERO for some amount of USDC. This will cause the discount rate to fluctuate with AERO/USDC volatility. But a buyer will be required to pay the same amount of USDC specified in the listing. Pro tip: it's much simpler if we all just buy and sell using AERO.
# Listings
There are two types of "for sale" listings that can be created by NFT sellers.
1. Fixed price
* Priced in either AERO, USDC, or WETH
* Price remains unchanged in the selected currency
* 1% fee to the seller collected upon sale
2. Dutch auction
* Priced in either AERO, USDC, or WETH
* Starting discount (e.g. 10%)
* Ending discount (e.g. 20%)
* Auction duration (e.g. one week)
* Price gradually moves from starting discount to ending discount
* Price remains at ending discount after the auction duration if not sold
* 1% fee to the seller collected upon sale
All listings expire after 60 days if not sold.
#### Indicators
We've added small icons to highlight listings that meet certain criteria.
* **Dutch Auction time remaining**
The discount rate for this listing will gradually approach its max until the ending time. Hover over the icon to see the ending discount and scheduled auction deadline.
* **Great deal!**
These listings each have the lowest discount relative to other listings of similar size. You can see this visualized on the Discount vs Lock Size chart with the yellow dots.
* **Vote can be changed immediately**
Holders of veAERO or veVELO can only change which pools they vote on once per epoch (week). Some buyers prefer locks where the vote can be changed during the current epoch instead of having to wait for up to a week. This is particularly helpful for buyers who want to participate in an [Ignition](https://x.com/AerodromeFi/status/1980741852094750954) launch.
* **Has unclaimed rebase**
These locks have pending, unclaimed rebase (see [Aerodrome Tokenomics](https://aerodrome.finance/docs#tokenomics)). This indicates that the effective discount rate may be *better* than what's advertised. For example, imagine a 1,000 AERO lock that earns an additional 1 AERO rebase each week and is worth \~1,052 AERO after one year. If the owner lists it on Vexy without first claiming the rebase, it will be displayed as 1,000 AERO locked. Despite being advertised at a 20% discount (`800 / 1000`), the effective discount rate would be closer to 24% (`1 - 800/1052`).
Sellers who leave the rebase unclaimed often also leave voting rewards unclaimed. This is usually just dust but can be a meaningful amount of rewards. We recommend doing your own research on potentially mispriced listings. This indicator just serves as a tip that there may be an opportunity to investigate.
# Offers
Standing "want to buy" offers can be created by users who desire a lower discount rate than what's currently listed. Unlike "Offers" on other marketplaces, Vexy Offers are not limited to individual NFTs or existing listings. They are global offers indicating that you are willing to spend up to X amount of AERO at Y discount.
This novel feature allows for the demand side of the order book to be established. Traditional NFT marketplaces lack this critical element necessary to foster a healthy exchange and reliable liquidity for these assets. Offers allow sellers to instantly sell veAERO instead of listing and waiting for a buyer to make a purchase.
\
**How to place an offer**
To place an offer, select the green "Make Offer" button and input your budget in AERO along with your desired discount percentage. You’ll be asked to submit two transactions in order to create your offer: approve funds and make offer. \
\
It’s possible for your offer to get partially filled by smaller NFTs that don't max out your budget. In this case, the remainder of your offer will remain open. You will only be charged for the amount of veAERO you receive.\
\
Your offer will expire after 60 days.\
\
**How to accept an offer**
The easiest way to accept an offer is to navigate to "My Portfolio" from the header menu. Under "My NFTs" you will see a list of the veAERO NFTs you own along with the best existing offer for each NFT. Select "sell now" to instantly sell your NFT into that offer. You will be prompted to review and confirm before proceeding with the transaction.
You can also view the global list of offers by selecting the "Offers" tab on the main listings view. There, you will see an overview of all offers, which may or may not pertain to any of your NFTs. From there, you can select "Accept Offers" and you will be taken your portfolio page to complete the transaction. If "Accept Offers" is disabled, you don't currently own any qualifying NFTs.

# FAQ
## Getting Started With Aerodrome’s veAERO and the Vexy Marketplace
New to the veAERO market? We’ve answered some of the most commonly asked questions about Aerodrome (AERO) locking and veAERO below to help you get started.
If your question isn’t answered below, feel free to reach out to the team via our vexy.eth or vexy.base.eth ENS domains. You can also get in touch with the team on Discord:
### Where Can I view Aerodrome veNFT Listings?
You can view Aerodrome veNFT listings on the Vexy marketplace [homepage.](https://vexy.fi) Vexy aggregates veAERO listings from multiple sources, letting you view nearly all veAERO listings that are currently for sale.
### What are Aerodrome NFTs (veAERO)?
Aerodrome NFTs represent a users’ locked AERO and voting power. Vote-escrowed NFTs (veNFTs) follow a similar model to veTokens, such as veCRV, where a user’s voting power is a function of the amount of tokens locked and the lock’s duration.
### How Liquid is veAERO?
Want to lock AERO but unsure whether you can sell your veAERO position? Vexy’s marketplace makes it easy to sell veAERO. Based on historical volume, veAERO holders can sell their tokens within 24 hours at competitive discounts (10% to 35% depending on lock size). You can view [historical sales data](https://vexy.fi/) to get an idea of what discount rate your veAERO would sell for.
### How Does Aerodrome fund veAERO Staking Rewards?
Aerodrome staking rewards are generated from Aerodrome’s trading fees. To receive staking rewards, AERO holders must lock AERO for veAERO (Aerodrome’s veNFT). veAERO is an ERC-721 non-fungible token that represents a users’ locked AERO and grants governance rights over the protocol.
### How Can I Buy veAERO Using Offers?
Vexy’s offers feature lets you buy veAERO at your preferred discount rate. Navigate to the “make offer” section of Vexy’s marketplace, set your discount rate and budget, and confirm the offer in your wallet. Once placed, any veAERO holder with a qualifying NFT can sell into your offer.
Note that veAERO cannot be split, so offers with small budgets are unlikely to be filled. We recommend you place offers with a minimum of 1,000 AERO at a competitive discount rate to get your order filled quickly.
### How Long Will It Take for My veAERO Offer to be Accepted?
The time it takes for your veAERO offer to be accepted depends on how competitive your offer is. Competitive offers for smaller budgets require smaller discount rates, while users with larger budgets could get their offers filled at higher discount rates. You can view [historical sales data](https://vexy.fi/) on the Vexy marketplace to get an idea of what kinds of offers will get accepted.
Your veAERO offer will be valid for 60 days and can be cancelled at any time.
### How Can I Stake AERO for veAERO?
You can stake AERO for veAERO on the [Aerodrome dapp.](https://aerodrome.finance/locks) By staking AERO for veAERO, you can earn Aerodrome trading fees and vote on which pools receive AERO incentives. Alternatively, users can purchase veAERO on Vexy to acquire locked AERO at discounted pricing.
### How do veAERO Dutch Auctions Work?
veAERO holders can use Dutch auctions to help get the best price for their veNFTs on Vexy’s marketplace. Dutch auctions gradually lower your veAERO discount rate over a set period of time until your veAERO is sold. This helps you get the highest price for your veAERO while allowing you to sell your position quickly.
### How Can I get In Touch With the Vexy Team?
You can get message the Vexy team in the Vexy Discord (), or you can reach out to us on DeBank using the official Vexy account ().
