NOM's Bonding Curve (BC)

Bonding Curve Contract: 0x264C13cfEd981e3137Fb43B198D14D8D5D64977E


Bonding curves are crypto-economic token models that automate the relationship between price and supply. It is a decentralized automated market maker that is on-chain with community-driven liquidity. Liquidity within the automated market maker cannot be controlled by any central entity. The code cannot be adjusted after its deployment. The tokens in this model are referred to as Continuous Tokens because their price is continuously calculated. In continuous token models, there is no ICO or token launch. Instead of pre-selling tokens during a launch phase, the tokens are minted continuously over time via an automated market maker contract. Tokens are minted when purchased as needed, in conjunction with demand, and used within the protocol or application when required or desired. Continuous Tokens have other properties such as instant liquidity and deterministic price. Bonding curves act as an automated market maker such that token buyers and sellers have an instant market. Additionally, bonding curve models don’t have central authorities responsible for issuing the tokens. Instead, users can buy a project’s token through a smart contract platform. The cost to buy these tokens is determined by the supply of those tokens. Unlike traditional models, the cost of these tokens increases as the supply increases. This price is determined by a pre-existing algorithm, further described below. A fee of 1% is applied per trade with the bonding curve. The Bonding Curve Contract has been audited by NCC Group, an enterprise-level cybersecurity firm headquartered in the United Kingdom.

bNOM to NOM Distribution

The Onomy Protocol token (NOM) is primarily distributed through a bonding curve contract deployed on the Ethereum Network where bondingNOM (bNOM) tokens are purchased that are bridged 1:1 for NOM on the Onomy Network. NOM is the native utility token of the Onomy Network. An interface is provided for this exchange at - commonly referenced as "bridging" bNOM tokens from Ethereum and into the Onomy ecosystem for native NOM. When bridged, bNOM is burned from the bonding curve, and an equivalent amount of NOM is provided on the Onomy Network.
The following is the equation governing the bonding curve:
100,000,000 is the supply of bNOM loaded into the bonding curve. Supply is provided as it is purchased, thereby acting as a minting mechanism over time. The emission of tokens requires significant capital to prevent over-dilution of the NOM circulating supply.

Distribution Benefits

The bonding curve has many benefits:
  • Deterministic Price: The buy and sell prices of tokens increase and decrease along the price curve.
  • Continuous Price: The price of token n is less than token n+1 and more than n-1.
  • Instant Liquidity: Tokens can be bought or sold instantaneously at any time, with the bonding curve acting as an automated market maker. A bonding curve contract acts as the counterparty of the transaction and always holds enough ETH in reserve to buy bNOM back. Note that once bNOM is bridged for NOM, it cannot be bridged back for bNOM.
  • Collateralization: In conjunction with the staking inflation curve, ETH acts as reserve backing of the bNOM.

Staking & Bridge Incentives

The Onomy Network Staking Curve carries a tight relationship with the Bonding Curve. The staking curve acts as a principal motivator for participants who purchased bNOM to bridge from Ethereum to the Onomy Network to capture the opportunity to obtain staking rewards. NOM holders can either choose to become validators themselves, or delegate their NOM to a validator to earn staking rewards minus a validator fee.
The staking rewards incentivize bNOM on the bonding curve to bridge into NOM, thereby driving value into the Onomy Ecosystem. Once bridged, bonding curve participants formalize their entry into Onomy and relinquish the ability to sell back to the bonding curve. Liquidity for NOM is not guaranteed, nor are secondary markets.
The bonding curve is perpetual until all 100M bNOM are issued.

Revenue Disclosure

The Bonding Curve Automated Market Maker (AMM) earns revenue in two ways. The first is a 1% transaction fee applied to each trade with the AMM. The second is the release of Ether used to purchase bNOM in proportion to the amount of bNOM bridged to the Onomy Network. These two methods together constitute the "Revenue" of the bonding curve. Revenue is currently distributed to PENDULUM LABS LIMITED as voted by the Onomy DAO Proposal 5. PENDULUM LABS LIMITED may only obtain the Revenue in the manner described above and has no ability to change, manage, or otherwise alter the Bonding Curve smart contract that has been deployed to the Ethereum Mainnet.

Risk Disclosure

The Bonding Curve Automated Market Maker is a decentralized protocol that people can use to create liquidity and trade bNOM tokens, as well as convert bNOM (ERC-20) for NOM tokens on the Onomy Network one-for-one. Your use of the Bonding Curve Contract and its Platform involves various risks, including, but not limited to, losses due to the fluctuation of prices of tokens in a trading pair or smart contract vulnerabilities. You are responsible for doing your own diligence on those interfaces to understand the fees and risks they present.
THE BONDING CURVE CONTRACT AND PLATFORM IS PROVIDED "AS IS", AT YOUR OWN RISK, AND WITHOUT WARRANTIES OF ANY KIND. Although PENDULUM LABS LIMITED developed the code, it does not provide, own, or control the Bonding Curve Contract or Platform, which is run by smart contracts deployed on the blockchain. No developer or entity involved in creating the Bonding Curve Contract or Platform will be liable for any claims or damages whatsoever associated with your use, inability to use, or your interaction with other users of, the Bonding Curve Contract or Platform, including any direct, indirect, incidental, special, exemplary, punitive or consequential damages, or loss of profits, cryptocurrencies, tokens, or anything else of value.
