Ampleforth ($AMPL) review: The essential guide to this DeFi protocol

Ampleforth is a game changer that is claiming the spotlight on Decentralised Finance (DeFi) following the success of several lending platforms such as Compound ($COMP), Aave ($LEND), dYdX, etc. Ampleforth is a DeFi protocol that aims to reinvent money both within and beyond the cryptocurrency space. While centralized finance (CeFi) and DeFi as we know today have their own unique sets of problems, the Ampleforth protocol is here with the aim to address them.

The protocol has a native token known as $AMPL. It is a stable currency that has both inflationary and deflationary capabilities designed to adapt to demand.


Ampleforth was created by Evan Kuo, an engineering graduate of UC Berkley. He was also the former CEO of Pythagoras Pizza, the first pizzeria to tokenize its franchise.

Kuo’s motivation for creating Ampleforth was twofold. The death of his father, which made him want to leave a legacy after his passing, and his passion for tech and finance which brought him into the cryptocurrency industry.

He recognised two things that cryptocurrency was trying to reinvent: money and banking. Of the two, money was a lot easier to work with and so that became his focus.

The Ampleforth Foundation was then funded by Pantera Capital, True Ventures, Huobi exchange and Brian Armstrong. Most of the members of the foundation consist of “engineers, academics, investors, and enthusiasts” from Ivy League universities.

Ampleforth raised a total of nearly $10 million USD in 2 Initial Coin Offerings (ICO) and an Initial Exchange Offering (IEO).

Ampleforth Protocol

Ampleforth Protocol is a cryptocurrency ecosystem built on the Ethereum blockchain. What makes it stand out is its adaptive supply, that is to say, Ampleforth adjusts the circulating supply according to demand.

When the demand for Ampleforth increases, the supply increases. Conversely, when demand decreases, the supply also decreases. This makes Ampleforth prone to being mistaken as a stablecoin since it does function quite similarly.

However, it is not backed by any cryptocurrency or fiat currency like most stablecoins are. And although the system attempts to keep the value close to $1 USD, sometimes it could go way past $3 USD depending on the demand.

As of press time, $AMPL is trading at $1.64 USD according to Coin Market Cap.

The Ampleforth Protocol is autonomous, but not decentralized. The Foundation still holds the keys to the system, and have the power to freeze all assets or change token supply arbitrarily. So for some decentralization purists, this is a red flag.

Ampleforth Monetary Policy

Kuo came up with Ampleforth’s economic design after examining the history of the U.S. Dollar. Back in the day, every U.S. Dollar bill was backed by gold bullions, which were stored in government vaults. Gold is a great store of value but it has an inflexible supply. Furthermore, going by the gold standard alone runs the risk of runaway deflation.

After World War II, the Dollar was in high demand globally and the U.S. couldn’t keep up. The amount of gold is fixed since mining can only introduce very small amounts of new gold in a given timeframe. Therefore, the U.S. government decided to abandon the gold standard to avoid stagnation of international trade.

And that became the birth of the fiat U.S. Dollar, which we now know has its own set of shortcomings. One problem with fiat money is that you could only print more of them but not destroy them. Therefore, the supply can only be partially controlled in a sense. Furthermore, the people in charge of the minting facility is also subject to greed and corruption.

Ampleforth’s monetary policy is a solution to both fiat and gold-backed currencies since it is designed to maintain a stable value by adjusting the supply to match demand.

As an illustration, say you have 1 AMPL worth $1 in your wallet. If the demand for AMPL rises and causes the price to jump to $2, the Amplforth Protocol will expand the supply of AMPL such that you’ll end up with two AMPL in your wallet worth $2. This process is called a “rebase”.

The rebasing process does not dilute existing token holders. You get to retain the same percentage of the total supply yet the value you held doubled.

Ampleforth use cases

Ampleforth divides its use cases based on its goals: near term, medium term and long term use cases. In the near term, AMPL aims to diversify cryptocurrency portfolios. Most cryptocurrencies are correlated to Bitcoin’s price pattern, which poses a risk. But because of AMPL’s rebase mechanism, it is decoupled from Bitcoin’s price pattern and allows cryptocurrency traders to have some diversity in their portfolio.

In the medium term, Ampleforth aims to work as a stable store of value or form of collateral for decentralised banks and DeFi applications. This is because unlike fiat-backed stablecoins, it does not pose the risk of devaluation of its underlying asset.

Ultimately, Ampleforth hopes to become a “A better Bitcoin”. It wants to be an alternative to central-bank money that can adapt to sudden shocks in the market. In that sense, it is competing with Bitcoin and XRP; not to mention national currencies. But as of the moment, it is being used primarily in the cryptocurrency space.

Another opportunity it offers is arbitrage. Arbitrage traders have the chance to reap profits during the time the supply is reduced when the price rises. On the other hand, they can increase their AMPL allocation before the supply is increased when the price drops.

How the Amplforth ($AMPL) rebase process works

The supply of Ampleforth adjusts daily every 1pm EST to match the demand via a smart contract. The system utilizes Chainlink’s oracle network alongside the Ampleforth oracle to siphon price data from KuCoin and Bitfinex.

The smart contract ensures that Ampleforth sticks within the designated equilibrium range, which is between $0.96-$1.06. If the price of AMPL hits beyond the two extremes, the smart contract will continue to “expand” or “contract” accordingly until the value of the token is in the equilibrium range again.

Ampleforth Geyser: What is it?

Ampleforth Geyser is a smart faucet that incentivizes liquidity providers to supply AMPL to a Uniswap pool. It is brought about through a collaboration between the Ampleforth Foundation and Uniswap.

Users are rewarded with AMPL tokens for depositing AMPL to Uniswap. The longer the tokens are held in the pool, the higher the returns.

To make money from Geyser, visit their web portal at and connect either your MetaMask or Coinbase wallet. You will need to deposit equal amounts of ETH and AMPL to participate.

How do I get AMPL tokens?

Aside from getting AMPL tokens during the rebase process (though this requires you to stake some AMPL in the first place), people can also buy AMPL from cryptocurrency exchanges. Here are the major exchanges that offer AMPL tokens for sale: Uniswap (v2), KuCoin, FTX exchange and Bitfinex. Learn more about our picks for the top best cryptocurrency exchanges of 2020.


Ampleforth has to some degree successfully redesigned the way money works despite only being a few years old. Their influence has not penetrated a huge portion of the market as of yet but there is a lot of room for them to grow. And being part of the DeFi movement makes it a lot easier to gain more traction. As a matter of fact, over 36 million AMPL has been deposited in Geyser as of now. This is a great stepping stone for the protocol.

Ultimately, Ampleforth’s goal is to compete against national currencies, and perhaps against Bitcoin as well, to become the world currency. For now, Ampleforth should work on establishing its trust and legitimacy within the cryptocurrency community, which will be a stepping stone for it to achieve its use-cases.
