We’re excited to announce that Matcha is upgrading our backend infrastructure to support 

delivering the best prices on the market to our users

.

Since the launch of Matcha just 8 months ago, Matcha users have securely exchanged over $4 Billion in value and have saved millions thanks to our aggregated order routing system enable by 0x. With our upgrade to 0x V4, these savings will get even better by delivering up to

 70% savings on gas costs and making Matcha up to 4% cheaper to trade through than Uniswap

Sushiswap, or any other DEX interface directly.

While these initial savings improvements are massive, they are not the end by any stretch. In the coming months, we’ll also be rolling out support for additional savings improvements including an estimated 10% improvement on limit order pricing, additional liquidity sources, and much more.


Starting today, existing Matcha users can begin taking advantage of these savings by:

We're thrilled to be partnering with RabbitHole, a new platform that rewards you for interacting with different Ethereum products! To celebrate this launch, in addition to the standard XP that you earn for completing various RabbitHole tasks, anyone who completes all of the Matcha specific tasks will earn a bonus reward in ZRX tokens (while supplies last).

RabbitHole is a platform that tracks your progress down the crypto rabbit hole. There are two objectives in RabbitHole: 1) complete quests and increase your XP, which entitles you to exclusive rewards in the future, and 2) complete tasks to earn tokens by completing campaigns.

Campaigns are application-specific and require the user to complete single or multiple tasks. If the user completes all the tasks before the rewards run out, they are eligible for the token reward.

RabbitHole is a web3-native application that sits on top of a querying layer and uses your Ethereum public key as your identity, watching your smart contract interactions across multiple Ethereum smart contracts. If you’ve completed a task on RabbitHole, you’ll be notified that you’re eligible to redeem the quest when you visit RabbitHole again.

Our initial campaign will run from December 7 - 14, 2020, with the following tasks:

Swap from any token to a stablecoin on Matcha

Swap from any token to a yield farming token on Matcha

The first 1,000 users who complete all three tasks will be awarded 250 XP + 15 bonus ZRX tokens.

Users who complete the campaign beyond the first 1,000 will still receive XP but not the bonus ZRX tokens.

Users will receive XP for each task completed but will only receive the bonus ZRX tokens upon completing the entire campaign (i.e., all three tasks).

Users must be fully verified with BrightID to receive the bonus ZRX tokens. This can be done at any point before submitting the completed campaign or after submission.

Ampleforth is a new type of "rebase" cryptocurrency. The 

 token, while not a stablecoin, targets being in parity to the purchasing power of the 2019 US Dollar. To accomplish this, the total supply of the token changes daily. At the same time, however, the overall ownership percentage of each holder is kept the same.

The properties of a base money influence the behavior of the financial stack built on top of it. Ampleforth is designed to be a base money that combines two previously incompatible properties: elastic supply and rules-based governance. The Ampleforth Foundation is building pieces of the financial stack that take advantage of this unique combination of attributes, further expanding what decentralized finance can accomplish.

A base money is the most elemental unit of value in a financial stack. This means that its value does not derive from convertibility into another currency—unlike casino chips, for example, which you must cash in to use outside of a casino. For this reason, the intrinsic attributes of a base money affect the financial stack and financial functions built upon it.

Fixed-supply assets like gold have been used as base money in many world economies, including the US, prior to 1971. Because the supply of gold is finite, the gold price can skyrocket in times of sudden and high demand, creating a ripple effect through the credit money system it feeds. Contracts or notes settled in gold during a demand spike are affected, as suddenly the payback value is more costly.

 of July 1944 sought to fix this. It created an international currency exchange pegged to the USD, which was, in turn, pegged to the price of gold. It also created two new international institutions; the IMF and the World bank. The agreement's goal was to add more levers with which world leaders could affect international trade through money supply, like fractional reserve banking and international lending, while maintaining gold as the base money.

Participating countries agreed to peg their national currencies to the USD, and the US agreed to keep enough gold reserves to cover all USD in circulation. Concurrently, the IMF and World bank provided outlets to create currency supply flexibility, which participating countries believed would help mitigate spikes in demand caused by the system's reliance on gold, a fixed-supply base money.

Over the next several decades, the downsides of using a fixed-supply asset as the foundation for a complex financial system became increasingly evident. No amount of tweaking the financial stack built on that foundation could fix all of the systemic problems that arose. In 1971, due to the concern that the US gold supply was inadequate to cover dollars in circulation, the US decoupled USD from gold, undoing the Bretton Woods Agreement. Unbacked USD became the base money of the US economy.

Fiat-based-monies like the USD have a flexible supply, which is modulated by central banks. Central banks can increase or decrease the money supply—whether by changing interest rates, asset purchases, etc.—to meet their stated policy goals. In the US, the Federal Reserve, for example, seeks price stability and full employment.

However, throughout history, elastic supply almost necessarily implies governance by discretion, not rules. This is because only a fiat money that is not convertible into a fixed-supply asset like precious metals can be issued or removed from circulation with the degree of control needed. The ability of central banks to create or destroy portions of the money supply makes them attractive targets for political pressure or regulatory capture.

Fiat monies have supply flexibility but governance concerns. Monies built on fixed-supply assets have some governance immunity but supply rigidity. This is where the Ampleforth token, 

, fits in; by providing a base money with an elastic supply governed by rules, not discretion.

AMPL was designed to be the most straightforward solution to supply inelasticity, and thus an effective building block for the future of decentralized finance. This is how it works:

AMPL is a decentralized digital currency that automatically adjusts supply daily, based on market conditions. This adjustment is called a 

. During a rebase, oracles capture the market price of AMPL. Suppose the price is above or below the target price. In that case, the protocol will automatically inflate or deflate the supply of AMPL across all user wallets, universally and proportional to how much AMPL each user owns. In this way, AMPL is non-dilutive, so the percentage of one’s ownership of the network remains fixed through the rebase.

The rebase incentivizes counter-cyclical price pressure, as short term market actors seek to capitalize on perceived value discrepancies. For example, when demand for AMPL increases, and the price climbs above the target price, the protocol automatically inflates the supply during the daily rebase. Since AMPL owners now have more tokens, short-term holders are incentivized to sell their AMPL to capture their sudden value increase. More sellers mean downward price pressure towards the target price, ultimately encouraging structural stability no matter if demand spikes or wanes.

The Ampleforth Foundation introduced the AMPL as a rules-based, elastic token that could make unique and innovative contributions as a building block for decentralized finance. Next, the Ampleforth Foundation aims to build out “Elastic Finance,” that is, financial-function protocols that can natively make use of unique elastic assets like AMPL. The 

 to achieving that goal is expressed here as a stack. The foundation builds vertically up the stack and horizontally across blockchains, creating a cross-chain value highway.

In order to realize the Ampleforth mission of becoming a new base money used as a building block for the future of finance, there must be low-friction ways of obtaining and using AMPL. The foundation promotes AMPL adoption through its 

. Geysers are smart faucets that incentivize on-chain liquidity. Users receive AMPL for providing liquidity on automated market making platforms (AMMs) like Uniswap. The more liquidity a user provides and the longer the timeframe supplied, the more significant share of the AMPL pool you receive.

 are fundamental needs in any financial stack, including a decentralized, elastic one. AMPL exhibits unique properties that make it an attractive asset for these use cases. For example, debts can be denominated in AMPL so that their real value remains relatively stable. This allows protocols to natively and in a decentralized manner, place the exchange-rate risk with the lender, not the borrower.

Healthy money markets benefit from access to futures contracts and insurance contracts. The Elastic Finance Stack would not be complete without on-chain versions, purpose-built for elastic tokens like the AMPL.

Ampleforth is committed to the long-term vision of creating tools for the future of decentralized finance. That began with releasing the AMPL, the world’s first elastic, digital token, and continues as the foundation builds up the Elastic Finance Stack and across chains.

RenVM is an interoperability protocol for decentralized finance (DeFi), allowing anyone, anywhere to move digital assets between blockchains.

RenVM brings interoperability to DeFi, which allows assets like BTC, ZEC, and others to be used within the Ethereum ecosystem (DeFi) and other smart contracting platforms.

The easiest way to imagine RenVM is to first think of it as a custodian that holds your digital assets as they move between blockchains. You provide BTC to RenVM; it holds that BTC, and then 

 (a.k.a. renBTC) on Ethereum with 1:1 ratio to ensure the same amount of BTC always backs your renBTC. This approach applies to almost any digital asset and smart contracting platform. For example, RenVM can hold native Dogecoin and mint it on the Polkadot blockchain.

RenVM achieves interoperability because it serves as a “universal translator” or an adapter of sorts. It takes the blockchain’s native format and converts it to the format needed by its destination chain (e.g., RenVM takes BTC in its native form and converts it to an ERC-20, the Ethereum token standard).  More information on RenVM can be found 

’s native token and is used as a bond to run a node, which powers RenVM.

While anyone can run a node, to prevent the forging of identities, 100,000 REN tokens are required to register and run the node, thus ensuring good bond behavior. This also prevents malicious adversaries from running an unbounded number of nodes and overwhelming the network with misbehaving nodes.

Every time RenVM moves an asset from one blockchain to another, it takes a small fee. Nodes (and those who run them) earn these

Synthetix is a derivatives liquidity protocol allowing anyone, anywhere to gain on-chain exposure to a vast range of assets. It enables the creation of synthetic assets called Synths, which are derivative tokens tracking the price of other assets, including cryptocurrencies, forex, indices, equities, and commodities. These Synths are backed by 

, which is staked as collateral, entitling stakers to fees generated by Synth trades.

Synthetix allows people to gain exposure to assets on Ethereum they might not otherwise be able to access. It also solves problems of liquidity and slippage, as all trades between Synths are operated peer-to-contract. The protocol does all this without compromising on decentralization — traders retain custody of their funds at all times. Other decentralization trading options like AMM’s have major liquidity and slippage restrictions for most assets.

 token enables all of this — it gets staked as collateral to mint these Synths, creating a distributed liquidity pool. The incentive for SNX holders is that all contract exchanges between Synths generate trading fees, which are shared between SNX stakers. There is a correlation between the value of SNX and the number of Synths that can be minted into the system, which means there is a self-scaling mechanism built into the protocol.

5 short months ago, our small but mighty team released Matcha to the world. Today, we’re thrilled to share that we’ve surpassed over $1B in cumulative volume across just 55 tokens - and it’s all thanks to our passionate user base of thousands of traders from Hong Kong to the US to Finland.

To celebrate this milestone, and in response to the insatiable demand our users have for accessing more markets through Matcha, we’ve enabled over 1,000+ new tokens along with the ability to add custom tokens to Matcha through a best-in-class experience that ensures anyone in the world can access and trade any market on Matcha with just a few clicks.

Starting today, when you navigate to the 

 page, you’ll now be able to search all available markets and begin trading immediately with assurance that Matcha will do the work to find you the best price for your trade across over 14 sources of liquidity. What’s more, because of the incredible work our team has done to create a custom routers for sources like Uniswap, it’s always cheaper to trade through Matcha than directly at the source.


Separately, if you find yourself unable to locate a specific token that you’d like to trade, you can follow our simple 

 to add the contract address and begin trading instantly.

We’ve been extremely humbled by the response to Matcha in the few short months since launch, and we have much more planned before the end of the year that will continue to make Matcha the best place to trade tokens.

All the things!

 with the listing of DONUTs on Matcha! It’s exciting to watch Internet communities grow around tokens like DONUT, and we look forward to listing more tokens in this vertical. This simple guide covers the function of DONUT tokens and how to easily trade them on Matcha. Let’s dive in!

These tokens were originally released in October 2018 as “Community Points“ to the ETHtrader subreddit, which has 260,000+ members. Shortly after, though, the community voted to rename them to “DONUTs”. 

 to vote on community polls, grant special membership, and purchase the subreddit’s ad space.

How to buy and sell the r/EthTrader ad banner with DONUTs

The mechanism for buying and selling the ad banner is unique in that a Harberger tax is applied to each purchase. A Harberger tax is a concept popularized by the book called 

Radical Markets written by Glen Weyl and Eric Posner

1. The person who buys the banner sets the daily ad price. They can purchase multiple days of banner ad time.

2. Anyone can purchase it from them with their DONUTs for the set price, and the owner cannot refuse to sell at the current set price.

3. The person who owns the banner pays a tax on it (100% of the one-day banner price, daily) to keep the banner. Set the price too high, the more the owner pays in tax. But if it’s set too low, someone may buy it immediately.

4. If no one else buys the banner from the current owner, their banner image continues to be shown until the amount they deposited for the banner purchase is depleted.

5. When the banner is purchased, the DONUTs are sent to the original owner.

You can learn more about the philosophy and rationale behind this form of taxation 

The price of DONUTs is determined by the market, like any other token listed on decentralized exchanges. Matcha provides a simple interface to buy, sell, and trade DONUTs easily.

2. Register your Reddit account with MetaMask

3. Earn DONUTs by participating in the sub’s discussions (paid out weekly)

Transaction costs are too high, especially for single source orders

 Matcha needs more tokens listed (Big update coming soon, stay tuned!)

Matcha’s goal is to always find you the best price for your trade, plain and simple. We do this by aggregating more than 13 liquidity sources and intelligently splitting up your order across multiple exchanges. But often the best deal can be found on a single exchange like Uniswap. In those instances Matcha has always been more expensive than going directly to the source. However, we’re excited to say this is no longer the case!

Starting today, 

it’s now actually cheaper to access Uniswap liquidity through Matcha

 than it is to go directly to the Uniswap UI! This is all thanks to the ongoing innovation of

 about how Matcha stacks up against other DEXs.

Matcha outperforms other exchanges ~72% of the time by offering better prices after accounting for gas.

In addition to the Uniswap price optimizations we’re rolling out a few features we designed to give you more control and insight into your trades.


First, when reviewing your order we’ll now show you exactly how much money you’re saving by using Matcha. By comparing ourselves to the next best option.


Next, you’ll notice that most markets on Matcha now have depth charts enabled. Depth charts assist traders by providing an x-ray view into where liquidity is coming from. Drag your mouse over to see how your trade might be distributed across different exchanges in order to receive the best rate.

Finally, in order to have more control over how your trade is executed, we’ve introduced advanced controls. These controls will allow you to toggle on and off liquidity sources, adjust maximum slippage and change gas speed.

Create your first limit order on Matcha for free today



Over the past few months, Ethereum’s gas costs have risen dramatically, which has resulted in extremely high transaction costs and difficulty for DeFi users to get the prices they want when trading. We have been aware of this issue for quite some time and have designed Matcha to give traders the tools they need to navigate these high fee environments. In this post, we cover how to create free limit orders and how we transparently display fees so you know exactly the price you’re paying on each trade.



Before diving into how to set limit orders on Matcha, it’s important to understand the difference between a regular market order vs a limit order. A

 is used when a trader wants to buy or sell a token at a specific price.



Limit orders are extremely useful when gas costs are high because traders can ensure that they receive the exact amount of tokens at their desired price without having to spend money on fees. Often times, market orders will fail because traders are not setting their fees high enough to be confirmed on-chain. Every time the order fails, they lose the amount they paid for the fee. On Matcha, all traders can set limit orders for free and can sleep soundly while they wait for their orders to be filled at their target price.

Unlike other decentralized exchanges (DEXs) that operate solely on-chain like Uniswap, Curve, Kyber, etc. Matcha does not store orders on the blockchain. Instead, orders are stored off-chain via 0x protocol, and only move on-chain to complete the trade. The maker of orders never pays fees, only the taker. This unique feature allows Matcha to offer free limit orders while other DEXs can’t.
