Bumper is a decentralized software application which establishes markets for measuring and exchanging blockchain-based asset price risk. It provides a set of mechanisms and functions which allow users to protect the value of cryptocurrencies (such as Ether (ETH), wrapped Bitcoin (wBTC), and others) by holding deposits of a price-volatile token for a fixed period of time. These deposits are pooled, and collectively incur a regular, dynamic premium. Those who take a price protection position in the protocol are known as “Takers”.
As these premiums accumulate, they are used to incentivise similar deposits of a price-stable token into a corresponding pool, which serves to back the protected value of the price-volatile token. The protocol makes the stablecoin available to individual Takers in the event of a claim. A position is able to claim the protected value from the stablecoin pool when the measured value of the backed cryptocurrency is below the individual floor price at the time of expiration. The originally protected asset is left within the protocol.
Those who make the stablecoin available in the protocol seek to develop a yield from negative price volatility of the backed cryptocurrency. They are known as "Makers".
Bumper is completely decentralised, autonomous and permissionless. Participants must lock a native protocol token (BUMP) into the system to access its cryptocurrency market functions and for decentralized community governance.
The system can be calibrated to withstand any price volatility scenario, however, tuning the system to withstand all volatility scenarios would result in untenably high premiums for Takers and low yields for Makers. To accommodate for a range of risk perspectives on each side of the market, participants select an engagement level which serves to segment them into risk-based tranches relative to one another. These segments are also used in calculating Taker premiums and Maker yields.
Bumper protects crypto assets against negative price movement when they are deposited by “Takers”, who are returned a tokenised version of the asset with the down-side volatility risk removed. The price risk is transferred to the opposing side of the market where “Makers” supply an alternative cryptocurrency that has a lower volatility; typically, a “stablecoin”.
Both the protected asset and the stablecoin deposited by Takers and Makers are held by the protocol in pools. Stablecoins are at risk for the benefit of Takers in the event of certain negative price events, and Taker assets incur a variable premium in the native asset for the benefit of Makers. Both the volatile cryptocurrency and stablecoin pools are partially subordinated, allowing actors to engage with the protocol according to their individual perspective on future price behaviour of the protected asset.
The Bumper design demonstrates how a decentralised software marketplace for asset price risk might prove superior to more traditional methods of using centralised stop-loss (which incurs slippage), or options markets (which has parasitic profits and overheads), by re-organising the utilities of the market participants.
