Bonding Curve
The Bonding Curve
A token bonding curve (TBC) is a mathematical curve that defines a relationship between price and token supply.
In a typical TBC, the price increases as the supply of the token increases, and decreases as the supply decreases. As the Aavegotchi Bonding Curve was launched through an Aragon Decentralized Autonomous Initial Coin Offering (DAICO), this article discusses DAICOs as well.

Mechanics
Minting / Burning on demand
Bonding Curves use a pricing algorithm to serve as an automated market maker and provide an always available source of liquidity. Users can interact with a bonding curve by staking tokens into the bonding curve’s reserve pool. When they do so, the bonding curve mints the corresponding tokens for the user based on the pricing algorithm. The newly minted tokens can have specific utility and even be traded among users, but can always be exchanged back through the bonding curve for tokens in the bonding curve’s reserve pool.
When a token is purchased via a TBC, each subsequent buyer will have to pay a slightly higher price for each token, generating a potential profit for the earliest investors. As more people find out about the project and the buying continues, the value of each token gradually increases along the bonding curve. Early investors who find promising projects early, buy the curve-bonded token, and then sell their token back can earn a profit in the future.
Formula
Bonding curves come in different shapes and sizes. For the Aavegotchi project, the team adopted the Bancor Formula:
Formula Explanation
The Reserve Token refers to the token that users stake into the bonding curve.
The Continuous Token refers to the token that is received from the bonding curve upon staking the Reserve Token.
In the case of Aavegotchi, the Reserve and Continuous Tokens are DAI and GHST, respectively.
The Connecting Weight (also known as Reserve Ratio) represents a fixed ratio (between 0 and 100%) between the Continuous Token's total value (total supply × unit price) and the value of its Reserve Token balance. This CW is constant by the Bancor Formula as both the Reserve Token balance and the Continuous Token’s total value (a.k.a. 'market cap') fluctuate with buys and sells.
Each purchase or sale of the Continuous Token (GHST) triggers an increase or decrease of Reserve Tokens (DAI). The price of the Continuous Token with respect to its Reserve Tokens must then continuously recalculate to maintain the configured Connecting Weight between them.
The Connecting Weight determines how sharply a Continuous Token's price needs to adjust in order to be maintained with every transaction, or in other words, its price sensitivity.
A higher reserve ratio between the Reserve Token balance and the Continuous Token will result in lower price sensitivity, meaning that each buy and sell will have a less than proportionate effect on the Continuous Token’s price movement. Conversely, a lower ratio between the Reserve Token balance and the Continuous Token will result in higher price sensitivity, meaning that each buy and sell will have a more than proportionate effect on the Continuous Token’s price movement.
Aavegotchi's Reserve Ratio is 33% frens! This means that whales can't pump & dump GHST as the bonding curve is hardened against their huuugge transactions!

Aavegotchi Bonding Curve
The Aavegotchi Bonding Curve was created on 14 September 2020 via a bonding curve smart contract powered by Aragon Fundraising. After the conclusion of a presale for 500,000 GHST, the bonding curve was immediately opened. The bonding curve is unlimited in size, has no time limit, and offers an opening price of 0.2 Dai per GHST. It has a connecting weight of 33%.
You will have to complete KYC in order to purchase straight from/sell to the curve. Compliance is important my dudes - we live in a society, and we also don't want the project to get rugged by the government. Purchases from the curve are made in DAI. The reverse also applies; you can sell your GHST back to the curve for DAI, but why would you wanna do that? :( :( :(
If you are unable to perform KYC because of your citizenship, don't worry! You will still be able to interact with every other part of the Aavegotchi metaverse. You simply have to purchase your GHST via other alternatives here.
Aavegotchi DAICO
A Decentralized Autonomous Initial Coin Offering (DAICO) is a new fundraising method that seeks to incorporate the best features of a Decentralized Autonomous Organization (DAO) with those of an Initial Coin Offering (ICO) in order to create a structure that provides a higher level of effectiveness to the token sale fundraising model. A DAICO is a model whereby investors have control over the funds collected once the fundraising is over. The investors could influence how developers have access to the funds and at what frequency through a "tap" mechanism. In addition, investors can also vote to do away with the project and have their funds returned.
The Aavegotchi project launched the token bonding curve through a DAICO on Aragon.
The Bonding Curve prevents investors from getting rugged as they ultimately have control over the funds within the DAICO/bonding curve!
The first iteration of AavegotchiDAO launched in tandem with the GHST distribution on the bonding curve. GHST holders had the power to vote on increasing / maintaining the funds distributed by the tap mechanism of the token bonding curve (TBC) reserve to Pixelcraft Studios (the team behind Aavegotchi) to support development. The first AavegotchiDAO proposal of increasing the Aavegotchi DAICO tap from 50,000 DAI to 100,000 DAI per month passed with 99% approval on 18 October 2020.
Closure of the Bonding Curve
In 2023, the DAO brought the closure of the bonding curve to a vote.
Following the passing of AGIP-64, the bonding curve was immediately closed, capping the supply of GHST. The DAI in the bonding curve was allocated in equal proportions (25%) to liquidity provisioning, the DAO, Pixelcraft, and protocol rewards (see AGIP-65).
A Curve transition team (see AGIP-66) was formed and a Curve transition plan was devised to secure funds for liquidity (see AGIP-67).
