Citadel.one is focusing on providing a range of high-quality Decentralized Finance products that are encased in a single platform. The team is developing 4 main features that make it a first Crypto Super App. These features include: 
- Citadel.One Validator Service 
The fundamental part of the Citadel.one concept is its Staking-as-a-Service business model. Currently, Citadel.one validates over 20 networks, including Tezos, Cosmos, Solana and others.
- Citadel.One DAO 
With Citadel.one DAO users can actually get more from their staking as XCT is rewarded for staking with Citadel.one nodes via Citadel.one platform. In that sense XCT is a securitized token, meaning it has intrinsic value based on basket of other crypto assets. XCT token also operates as a governance token, so users can be involved in platform activities directly — they can choose networks and features to integrate, vote for DAO financial and governance settings.
- The Citadel.one platform (Mobile and Web) 
Wallet functionality, staking, and extended portfolio analytics.
- Extensions 
With the introduction of extensions Citadel will be able to natively support any DeFi protocol or Dapp. It can be considered a crypto Wechat, a Super App with Dapps inside.

Opium is a new platform for launching and trading cryptocurrency derivatives.

Having begun operations in May 2020, Opium uses Ethereum to run a decentralized derivatives marketplace in which any cryptocurrency owner can participate.

The aim of the platform is to democratize access to financial derivatives while using the benefits that decentralization affords traders over legacy alternatives.

Opium’s in-house token, OPIUM, launched in January 2021 and will fulfil various roles mostly centered around platform governance. Active users will be able to vote on some of the most important decisions involved in the platform’s operations.

KardiaChain is a blockchain platform that aims to be fully interoperable and "non-invasive," meaning that blockchains can connect to the network without needing to make technical modifications to their own protocols. KardiaChain uses a dual-node structure to facilitate the connection between its own ledger and other blockchains, sharding for scalability and smart contracts for developers.

The platform relies on a native token, KAI, which is used for staking, transaction fees, participating in services and deploying smart contracts.

KardiaChain was first announced in October 2018, and its mainnet went live in December 2020.
