Acala wins Polkadot’s debut parachain auction

Decentralized finance protocol Acala was announced as the winning project in Polkadot’s inaugural parachain auction this week, beating fellow competitor Moonbeam to the finish line with a seismic total of 32.5 million DOT ($1.28 billion) raised from 24,934 contributors.

Acala is a multi-functional DeFi platform built on Polkadot that enables developers to build smart contract applications with cross-chain capabilities, as well as being compatible with Ethereum. Its top investors include Digital Currency Group, Polychain Capital and Alameda Research, among others.

In the case of Acala, all of the proceeds from the crowdloan initial coin offering are classified as “crypto debt” and, therefore, must be paid back by the project following the conclusion of the rental agreement.

Iota Foundation set to launch staging network and reward token

The Iota Foundation, an open-source, nonprofit entity endeavoring to support the Iota ecosystem, announced the upcoming launch of a staging network, Shimmer, this week alongside an accompanying token asset, SMR.

Shimmer is a layer-one sandbox platform that will enable builders and developers to test the efficiency and compatibility of their decentralized applications within the DeFi and NFT space, prior to deployment on the Iota mainnet.

Expected to launch in early-2022, the network will also facilitate community governance confirmations for Iota’s large-scale network upgrades, including the upcoming programmable multi-asset ledger, smart contracts, full decentralization and sharding.

Almost 50% of Uniswap v3 liquidity providers are in the red

A research report published this week by Topaz Blue and the Bancor Protocol revealed that almost half, 49.5%, of liquidity providers on Uniswap v3 have experienced financial losses due to impermanent loss, a common occurrence on automated market makers when supplying two-sided, volatile liquidity pairs.

An instance of this would arise if, for example, a user has supplied equal values of Tether (USDT) and Ether (ETH) in United States dollars to a liquidity pool and the price of ETH goes up.

This would mean that arbitrageurs — investors who often work in accordance with financial institutions to benefit from price discrepancies in the market — will remove ETH from the pool to sell at a higher price. This leads to a decrease in the U.S.-dollar value of the user’s position and, consequently, an impermanent loss.

The report suggested that, based upon current statistics, it may well be more profitable to simply hodl the market, as opposed to actively participating in liquidity services, stating:

“The user who decides to not provide liquidity can expect to grow the value of their portfolio at a faster rate than one who is actively managing a liquidity position on Uniswap v3.”
