Protocol

Overview of the EXA Market protocol.

Empowering users

The EXA Market protocol introduces a new range of possibilities for peer-to-peer trading on the Algorand network.

The protocol allows users to:

Trade both NFTs and fungible tokens
- Unlike Ethereum where NFTs use ERC721/ERC1155 standards and fungible tokens use the ERC20 standard, Algorand assets share the same standard called ASA (Algorand Standard Assets). This gives the ability to natively support a wide range of operations without any extra layer.
Exchange up to 4 assets* at once (bundle of assets)
- Up to 4 assets can be bundled for sales at the moment.
- For instance: a user could sell (ASA 1 + ASA 2 + ASA 3 + 100 ALGO) for (ASA 4).
- Important to point out that the 4 assets limit could be extended in the future according to market needs.
Sell NFT for any type of assets
- Users are not just limited to the native ALGO payment token, any type of ASA can be used as a payment method thus enabling NFT to NFT trades by design.
Make offers
- Negotiate with any user for both NFTs and fungible tokens.
Perform standard sales, auctions and multi-mints.

*assets here refer to NFTs and fungible tokens.

Sales types

As mentioned in the last section standard sales, auctions and multi-mints can be performed.

Standard sales

Baskets* are sold for a fixed price specified by the seller. This sale can be made public (to the market) or private (to a specific user) and can have start and end listing dates.

*basket(s) represent(s) the container(s) whereby assets are sold

Auctions

Normal auction – Potential buyers bid in an auction in order to claim the assets in the basket, and the highest bidder wins.
Reverse/dutch auction – The price of a basket is reduced according to the progression of time.

Multi-mints

A basket containing a supply of a single asset type, where different buyers can purchase portions of the supply available.

Creator fees

The Creator sets its fee (up to 15%) globally on-chain using its Creator Address. That means that all assets created by this address will be governed by this fee. In addition to earning royalties in ALGO, Creators could also earn royalties over time in the following currencies, if they have opted-in the assets. Here is the list of assets that the protocol currently supports as means of payment:

Asset

ASA ID

ALGO

N/A

USDC

USDT

gALGO

goBTC

goETH

goUSD

AKTA

xUSD

PEPE

COOP

mALGO

GORA

EURS

COSG

Finite

BLOOM

Listing of a single asset

Let’s say Creator has created 10 NFTs with Creator Address and sets its royalty to 8%. All of these NFTs will have a 8% royalty attached to them, meaning that 8% of the listing price will be paid to Creator whenever a sale occur.

Case study 1

Seller lists an NFT from Creator for 100 ALGO.

Buyer purchases the NFT:

8 ALGO goes to Creator
1.99 ALGO goes to Platform fee
90.01 ALGO goes to Seller

Case study 2

Seller lists an NFT from Creator for 200 USDC.

Buyer purchases the NFT:

16 USDC goes to Creator
3.98 USDC goes to Platform fee
180.02 USDC goes to Seller

Note that if the Creator has not opted-in USDC, the royalties will be sent to the Platform fee address. This is applicable for any ASA (USDC, USDT, gALGO, goBTC, goETH…etc).

Listing of a bundle of assets

The EXA protocol allows users to create bundles of up to 4 assets but how do the royalties are computed? Especially for bundles with assets from different Creators? Let’s find out in this section. The royalties are computed according to the following formula:

R = \frac{P}{N}\sum_{i}^{N} r_{i}

$R$ is the total royalties a Buyer will pay to the Creators
$P$ is the price of the listing
$N$ is the number of assets with a Creator fee set (> 0%)
$r_{i}$ is the royalty of asset of index i

Case study 1

Seller lists a bundle of 3 NFTs from Creator for 100 ALGO. Creator has 5% royalties set.

Buyer purchases the NFT:

5 ALGO goes to Creator

R = \frac{100}{3}\sum_{1}^{3} r_{i}=\frac{100}{3}\ \times (r_{1}+r_{2}+r_{3})=\frac{100}{3}\ \times (0.05+0.05+0.05)=5

1.99 ALGO goes to Platform fee
93.01 ALGO goes to Seller

Case study 2

Seller lists a bundle of 3 NFTs from Creator1, Creator2, and Creator3 for 100 ALGO.

Creator1 has 9% royalties set. Creator2 has 4% royalties set. Creator3 has 8% royalties set.

Buyer purchases the NFT:

7 ALGO in royalties goes to the Creators (Creator1, Creator2, and Creator3)

R = \frac{100}{3}\sum_{1}^{3} r_{i}=\frac{100}{3}\ \times (r_{1}+r_{2}+r_{3})=\frac{100}{3}\ \times (0.09+0.04+0.08)=7

3 ALGO goes to Creator1
1.33 ALGO goes to Creator2
2.66 ALGO goes to Creator3
1.99 ALGO goes to Platform fee
91.01 ALGO goes to Seller

Case study 3

Seller lists a bundle of 3 NFTs from Creator1, Creator2, and Creator3 for 100 ALGO.

Creator1 has 9% royalties set. Creator2 has 4% royalties set. Creator3 has 0% royalties set.

Buyer purchases the NFT:

6.5 ALGO in royalties goes to the Creators (Creator1, and Creator2)

R = \frac{100}{2}\sum_{1}^{2} r_{i}=\frac{100}{2}\ \times (r_{1}+r_{2})=\frac{100}{2}\ \times (0.09+0.04)=6.5

4.5 ALGO goes to Creator1
2 ALGO goes to Creator2
0 ALGO goes to Creator3
1.99 ALGO goes to Platform fee
91.51 ALGO goes to Seller

Algorand inheritance

Being built on Algorand, the protocol natively inherits essential features such as:

Low gas fee
- Network fees cost less than a penny. This limits the risk of paying more fees than the value of the asset itself, opening the doors to new users and use cases.
Low carbon footprint
- Its Pure Proof of Stake (PPoS) consensus algorithm makes Algorand a sustainable blockchain with very low power consumption in contrast to other chains. In addition to that it offsets its additional carbon footprint with environment-focused organizations (more details provided here).
Low block confirmation time
- It takes less than 3 seconds for a transaction to get validated.
