Liquid staking provides increased token utility for locked staked tokens. It allows users to leverage additional DeFi activities (such as securing Kintsugi vaults) using yield-bearing derivatives of staked tokens which otherwise have no utility beyond locking for staking rewards.

LIQUID STAKING 101

Users can compound their yield by utilizing the derivative token for engaging in DeFi activities, including things like trading, liquidity providing, or lending. Liquid staking provides a practical and flexible alternative to the traditional staking model by allowing users more control over their funds and greater access to additional earning opportunities.

Karura is Acala’s experimental “canary” network on Kusama. The DeFi appchain runs a suite of applications for the Kusama ecosystem, including Karura Swap, the AMM-style DEX for trustless trading and liquidity provider rewards, aUSD, an over-collateralized stablecoin, and KSM Liquid Staking (LKSM) — the unlocked, yield-bearing staking token that empowers users to stay liquid while earning their Kusama staking rewards.

Stay Liquid While Staking, and Utilize your LKSM on Kintsugi

In addition, Liquid KSM (LKSM) allows users to stake their KSM while maintaining access to its liquidity. When KSM is staked, users receive LKSM (a tokenized receipt for their stake) with the additional benefit of it being a yield-earning token.

Liquid KSM offers low staking minimums, and no unbonding period for the underlying KSM since users can unbond at any time for a fee. New to LKSM? Follow this guide to start staking your KSM on Karura for LKSM.

Sending your KSM to Kintsugi

Once you have your LKSM on Karura, the process of sending it to Kintsugi is quite simple. Just navigate to Karura’s bridge page, select Karura as the original chain and Kintsugi as the Destination chain and send it to your account on Kintsugi.

Registering a Multi-Collateral Vault on Kintsugi

A single Kintsugi Vault account can support more than one collateral asset.

After installing a vault client, you should follow this guide, which offers you different ways to register a vault. During the registration process, you will select the types of collateral you would like to use. Select LKSM as your desired option and then deposit it as a new collateral asset. Once this is done, the new collateral Vault will appear in the cards in the Vault dashboard.

The first web3 inbox, Notifi Hub, supports Aptos, Polygon, Acala, Ethereum, and Solana and aggregates new cross-chain integrations notifications and messaging into a single hub.

Notifi is building products for a multi-chain world. With new ecosystems popping up all the time, Notifi wants to cater to all users and environments by providing a communication infrastructure that suits any web3 need.

Overview

The first web3 inbox to combine cross-chain notifications and messaging into a single hub is called Notifi Hub. Users can currently track and manage all of their messages and alerts across various blockchains, wallets, and dApps in one place thanks to Notifi Hub. We at Notifi want to gather all of a user’s important web3 data under one roof. Anyone with an Ethereum, Solana, Polygon, Aptos, or Acala wallet can connect immediately through Notifi Hub!

The best way to think of Notifi Hub is as a web3 inbox. Similar to an email client, Notifi Hub gathers all messages and notifications from all subscribed dApps that are pertinent to you. Anyone can sign up for a variety of alerts, such as those for wallet transactions, security flaws, updates for dApps or DAOs, and more.

Another feature of the Notifi Hub that enables cross-chain messaging between users is xMS. Users of Solana and Polygon can communicate with Ethereum wallets via Aptos, and so forth. Simply connect your wallet to one of our many options, then leave!

How it Works?

Users must first access this website to start using Notifi Hub. You can sign up for the notification channels you want, such as email, SMS, and/or Telegram, after choosing which wallet to use. Checking the history of alerts is also possible using the native, in-app web3 inbox.

From Metamask and Phantom to Pontem and Unstoppable Domains, they support almost every wallet. You can link both your Ethereum and Solana wallets, for instance!

Users can click around and explore all the helpful features they have available after signing up and getting set up. Notifi Hub is packed with tools to enhance any cryptocurrency experience, from private transactions to whale watching and security alerts. If you’re not sure where to begin, we even have a carefully curated list of subscriptions from some of our partners available.

Notifi in a multi-chain world

There is no shortage of innovation in web3, and as a company that wants to build on the bleeding edge, Notifi is creating tools that can integrate across many blockchains and ecosystems.

They see user experience as one of the biggest hurdles for onboarding the next 100 million crypto users. Most users without prior web3 experience probably won’t care if they are using Ethereum or Solana. Instead, they want a seamless experience that removes all of the complexities.

For instance, the typical iPhone or Android user is not familiar with the technology that enables these devices to communicate with one another. Calls, texts, and even social media apps all function the same way and have a similar user interface across phones. A similar experience for blockchains should be provided, according to Notifi.

Notifi wants to be at the forefront of web3’s expansion to meet the needs of the general public by developing solutions that anyone can use and find useful. The success of their business and the widespread use of web3 depend critically on the effectiveness of the communication infrastructure.

About Notifi

Notifi is the Twilio for Web3. Notifi simplifies communication across all Web3 messaging channels. The Notifi platform is designed with simple APIs.

They are launching Astar and Acala DeFi Rising Campaign–solidifying one of our most important partnerships. Acala is pivotal to the booming ecosystem of dApps on Astar. Why? Because they have a suite of flexible financial products that serve the Polkadot network. Our two communities will be able to explore Astar’s vibrant DeFi ecosystem using Acala native assets, like aUSD, LDOT, and ACA, while receiving extra ACA and additional rewards from various Astar ecosystem teams.

Building a Strong Ecosystem through XCM

DeFi Rising is the first step to building innovation by leveraging the power of Cross-Consensus Message Format (XCM). Establishing Astar as the future of smart contracts for multichain requires having deep liquidity of institutional-grade assets, like aUSD and LDOT, for our builders to work with. Astar developers can build new dApps on top of Acala’s reliable assets, providing a foundation to expand our network. In return, our ecosystem will build the early use-cases needed for aUSD mass adoption across the multichain future.

Why this matters to the Polkadot ecosystem?

As this is the first official collaboration between two parachains on Polkadot, the initiative will highlight the capability of Polkadot to execute trustless and decentralized cross-chain transfers through XCM. With two of the biggest parachains working together, the potential of XCM to build value across ecosystems will be recognized by the builders outside of Polkadot–gaining their attention is a step towards expanding the developers-first Dotsama ecosystem.

Astar x Acala DeFi Rising

Astar x Acala DeFi Rising Campaign will invite major dApps on Astar to integrate with native Acala assets (i.e. aUSD, LDOT, and ACA) by offering extra incentives to eligible pools. It takes off on August 10, as ArthSwap–the one-stop DeFi on Astar Network–joins this campaign as the first project of Astar x Acala DeFi Rising!

Follow our social media: More Astar ecosystem projects are on the horizon! We will update as new projects join the campaign.

The extra incentives for this campaign will consist of increased token rewards from Astar dApps and ACA provided by Acala. Details for the first eligible pools are:

aUSD-WASTR Pool

Start: August 10
