Augmented Bonding Curve

Disclaimer: This is an open source app. None of the people or institutions involved in its development may be held accountable for how it is used. If you do use it please make sure you comply to the jurisdictions you may be jubjected to.

How does it work

This module provides market liquidity to the fundraising campaign by automatically matching all the buy and sell orders according to a bonding curve tied to the Bancor formula.

Initialization

Augmented Bonding Curve is initialized with:

• _tokenManager The address of the token manager contract
• _formula The address of the BancorFormula computation contract
• _reserve The address of the reserve pool contract
• _beneficiary The address of the common pool contract (to whom fees are to be sent)
• _buyFeePct The entry tribute to be deducted from buy orders (in PCT_BASE)
• _sellFeePct The exit tribute to be deducted from sell orders (in PCT_BASE)

Roles

The augmented bonding curve app implements the following roles:

• MAKE_BUY_ORDER_ROLE: Necessary to convert collateral tokens into bonded tokens.
• MAKE_SELL_ORDER_ROLE: Necessary to convert bonded tokens into collateral tokens.
• MANAGE_COLLATERAL_TOKEN_ROLE: Used to manage more than one collateral (many bonding curves can be managed with just one instance of the app).
• UPDATE_FORMULA_ROLE: Used in case we need to update the bonding curve formula.
• UPDATE_BENEFICIARY_ROLE: Used in case we need to update the funding pool address.
• UPDATE_FEES_ROLE: Used to change entry and exit fees/tributes.

The augmented bonding curve app should have the following roles:

• MINT_ROLE and BURN_ROLE: It should be able to create and destroy tokens from Token Manager.
• TRANSFER_ROLE: It should be able to transfer funds from the reserve pool.

Interface

Tokens can be converted using the convert frontend.
