What is Bumper in a nutshell?

Bumper is a DeFi protocol which protects your crypto from price drops and market crashes whilst simultaneously making sure you don't lose out in case the price pumps. Protection seekers pay a premium for doing so, which is earned by liquidity providers who deposit stablecoins, which are used to pay out claims.

How does Bumper protection work?

Users of protection set a floor price for their ‘unstable’ asset (eg. ETH), and if the price drops, their asset will never fall below that floor price. Importantly, if the price rises, they retain their native asset as the value increases, thus removing downside risk but still capturing the upside potential.

The Bumper protocol aggregates sellers of risk (Takers) and buyers of risk (Makers) into separate but decentralised, non-custodial pools. The protocol is constantly monitoring a variety of ratios governing the balance of those pools, and then uses incentivised mechanisms to retain that balance to provide the required price protection.

What benefits can Bumper provide to users?

Put simply, Bumper can provide protection for the price of your crypto assets. This means that the volatility that we have all become aware of in the crypto market can be mitigated in exchange for a fee.

As a result, you can invest into a cryptocurrency, and then 'bumper' some or all of it and wait until the value of that asset rises.

Then, at what ever point you want to sell your assets, you'll never lose less than your set price floor. Considering this, you could wait until the asset price rises and then Bumper that price, effectively removing any chance that your whole crypto portfolio will suffer from heavy losses. On the other side, Makers have the opportunity to earn yield, not only from premiums which are collected by the Bumper protocol, but also from the automated Yield farming capabilities which the system makes possible. All of these benefits mean that using Bumper can make crypto a sustainable long-term investment choice.

Isn’t Bumper just a Stop Loss?

A Stop Loss places a sell order to an exchanges order book when the threshold is triggered, converting your crypto asset to stablecoins or fiat (assuming the order is filled, which it isn’t guaranteed to be). But if the price rebounds, you end up missing out on upside gains.

Bumper preserves upside gains whilst protecting your wallet's value from drops without transferring your tokens to an exchange. Your token isn’t sold when the floor is crossed, unlike when using a Stop Loss.

Isn’t Bumper just a Put Option?

Bumper’s price protection is a novel alternative to the Put Option with significant benefits for both sides of the market.

You can buy a Put option without having to own any tokens. It’s essentially a gamble based on price movements with a fixed premium paid in advance. You either win, and thus can exercise your option (or just take profit), or you lose and are returned nothing.

Bumper protects tokens that you already own, and its premiums are calculated dynamically and applied incrementally, based on actual market volatility. When your position is closed you either claim stablecoins to the value of your floor, or you retrieve your original token (minus the premium).

Unlike a Put option, Bumper returns a composable ‘Bumpered asset’ to the protection taker. It also allows protection terms to be renewed (extended) if required.

On the other side of the market, yield seekers generate income over time without the need to continually price, write and locate buyers for Put contracts. Bumper’s pooled architecture facilitates earning from multiple different positions even while reducing exposure to losses from individual contracts.

Is Bumper easy to understand for new users?

The Bumper dApp is intuitive and very easy to use. On the app, it takes just a few clicks to get protected. We recommend taking a look at our repository of content which provides how-to guides, videos and a range of documentation to help you understand Bumper.

What is a 'Taker'?

A taker is a user who wishes to protect the value of their crypto assets by purchasing protection, and thus 'bumpering' their crypto. Takers pay a premium for their protection, and this is earned as a yield by Makers who provide the liquidity for claims made by Takers.

What is a 'Maker'?

A maker is a user who provides liquidity into the protocol by depositing Stablecoins into a Bumper capital pool.

Makers earn a yield for doing so, as they are assuming some of the risk from Takers.

Does Bumper have any fees?

Yes, and the protocol seeks to minimise fees to be as low as possible. The fees levied on Takers are a function of market risk; so as the market conditions degrade (i.e. with increased volatility or down-side risk markers), then the premium (fee) will adjust accordingly. This ensures that the fees only accumulate for the risk that the protected asset presents, meaning that they can be as low as possible.

The beauty in Bumper with this approach is that it doesn't have any long-term unsustainable incentives that we find in other protocols. The incentives balance in real time based on the internal state of the protocol and a measure of the external prices of the protected assets, including the fees for Takers and yields for Makers.

Why can’t I know the premium before I take out protection?

Bumper redefines risk markets in a novel and inventive way.

Using an Options desk, the premium is known up front, but the method in which it is calculated is not. This means that the cost is arbitrary, and decided by the seller alone.

Using Bumper, this opaque way of costing protection is not used. Instead, the method by which incremental premiums are calculated (based on the actual future volatility of the market) is known up front, with both sides agreeing that the method of costing protection is fair.

Do I need to verify my identity to use Bumper?

There are no KYC (Know Your Customer) or AML (Anti-Money Laundering) requirements, and we do not require you to register to use Bumper. Simply connect your compatible wallet, and you can use the protocol.

Doesn't the high number of daily transactions for a user's account incur some kind of additional risk?

No, the clever thing about the protocol is there's no real need to do lots of transactions.

Bumper works like an aggregated ledger, monitoring and maintaining the relevant ratios that keep the protocol stable, it limits that transaction security risk and reduces things like slippage down to an irrelevant problem.

Will Bumper expand to multiple networks?

Our native BUMP token is an ERC-20 token on the Ethereum and Arbitrum networks. In the future, we are looking at possibilities in expanding to other networks to reach more users in the crypto space.

How is Bumper able to deal with large drops in the market?

The protocol is extremely efficient and robust and more than capable of dealing with BlackSwan events.

Drops in price are a two-part problem. Firstly, the actual level of drop and secondly, the time it takes to drop and/or recover. The worst-case scenario is a big and fast drop with an elongated flatline. Bumper is well-equipped to handle those kinds of drops.

So, yes, Bumper can be tuned to in fact withstand any kind of market drop, and has undergone in-depth modelling of many different scenarios to ensure that the protocol is as robust and cost-effective as possible.

There is only one theoretical kind of market drop that Bumper cannot withstand, and that is if the price of ETH goes to 0 instantaneously and stays there for an infinite amount of time. So as long as that doesn't occur, then there are a set of parameters under which the protocol works.

You’ll need to read Bumper's technical documentation to fully understand the mechanics of how Bumper deals with flash crashes, but the protocol is extremely efficient and robust and more than capable of dealing with BlackSwan events and the kind of drops recently witnessed.

How do stablecoins work with the smart contract?

Users deposit stable coins into the Bumper protocol in order to open Maker positions. The Bumper smart contract balances both the pool of stablecoins with the more volatile crypto asset. For a more in-depth description of how the protocol's economic and rebalancing system works, we highly recommend reading the Litepaper.

What is the maximum amount of BUMP tokens that will be available?

The BUMP total supply is 250,000,000 (two hundred and fifty million).

What is the purpose of BUMP token?

The BUMP token is woven into every facet of the platform and is the first entry point to the Bumper ecosystem — since both protection “Takers” and liquidity providing “Makers” need to deposit BUMP tokens to begin interacting with the protocol. The token also acts as the governance token for the protocol, allowing users to stake their BUMP in return for voting rights. Read more about the BUMP token here.
