Legacy DDEX will move to open source on September 30, 2020. The UI interface at legacy.ddex.io will turn off at that time.

Back in early 2018, we launched the first form of DDEX which we now refer to as “Legacy” DDEX. We originally used 0x for our settlement, with a focus on wallet-to-wallet transactions for tons of token pairs. As time passed, it became clear that this strategy needed some adjustments: the ecosystem was shifting and we evolved alongside it.

We moved more deeply into the DeFi space, creating the new DDEX platform — we completely rewrote our smart contracts from scratch, focusing on utilizing high liquidity markets to power margin trading and lending in addition to spot trading. …

Neutral and DDEX Collaborate to Bring Superior Digital Currencies to the Decentralized Community

Neutral, an open financial protocol, has announced the listing of its first digital currency, a stablecoin called Neutral Dollar (NUSD) on DDEX decentralized exchange. Neutral Dollar is currently collateralized by a basket of stablecoins comprising DAI, TUSD, PAX, and USDC. Users can contribute any constituent stablecoin at fair value in exchange for NUSD during an initial contribution period from May 16th through the Neutral platform. …

A huge portion of daily cryptocurrency trading volume currently lies in Bitcoin (BTC) based trades. As an Ethereum based exchange, there is an inherent challenge in reaching traders that trade in BTC — even if we have trading pairs they might use, the fact that we don’t have ALL of their pairs can cause friction. The continual shifting of funds back and forth from centralized platforms to decentralized wallets is not only costly (yay deposit/withdrawal fees!), but inconvenient and slow. …

Token prices dropping on a volatile crypto day, yet DAI remains stable as ever.

DDEX now offers 4 trading pairs utilizing Dai as the base pair

WETH-DAI, MKR-DAI, ZRX-DAI, and OMG-DAI are all active markets now. Dai is the first non-WETH base pair on DDEX! In the first couple weeks of Dai trading, we have already seen over $1m USD worth of trading volume on these four trading pairs.

Dai is a decentralized “stablecoin” —a digital asset designed to maintain a consistent price, often pegged to a fiat currency like the US dollar or collateralized against commodities like gold. Dai’s value is held constant with the US dollar, such that 1 Dai equals 1 USD.

Why Stablecoins?

DDEX reached a new milestone of 25,000 users and currently ranks #2 on Etherscan’s DEX tracker


DDEX, the first Hydro Protocol based 0x Relayer, just cleared a couple of noteworthy milestones after first launching open beta testing in January of 2018. We are extremely grateful for the tremendous amount of support from both our community and the 0x project team throughout these last several months.

While there is still a long road ahead to reach our vision of a predominately decentralized ecosystem, it’s important to celebrate major milestones as we grow. This is a small achievement along the path towards a much greater vision for not only our team, but for all decentralized exchanges/relayers.

A massive…
