How about the Polkadot ecosystem?
"Kusama- Kusama is often considered to be the testing ground for Polkadot projects. Described as the âcousinâ of Polkadot, Kusama was also built on Substrate and was created by Polkadot co-founder Dr. Gavin Wood in 2019, using an almost-identical codebase to Polkadot. Although it is often referred to as the âtestnetâ for Polkadot, Kusama has provided a versatile environment that has assisted in the rapid growth of several top Polkadot projects.
Moonbeam- Moonbeam is an interoperable platform for smart contract deployment that will allow users to easily bridge Polkadot and Ethereum. The Moonbeam utility token âGlimmerâ (GLMR) will be used for transaction fees when executing and interacting with smart contracts.
Centrifuge- Centrifuge is a Polkadot-compatible protocol for decentralized financial assets that serves as a âgateway for real-world assets into DeFiâ. Working in conjunction with MakerDAO, Circle, and Celo Protocol, Centrifuge facilitates borrowing and lending on the blockchain. Moreover, users can take out loans using real-world assets as collateral. For example, using Centrifuge, it is possible to take out a loan using invoices, mortgages, and other tokenized assets as collateral. Centrifuge has two key components, Centrifuge Chain, and Tinlake.
Edgeware- Edgeware is a âself-improving smart contract blockchainâ built for the Polkadot ecosystem. Development of the Edgeware blockchain is sustained by the Edgeware on-chain treasury, which is run by elected network participants.
Polkastarter- Polkastarter is a crypto launchpad and fundraising platform that facilitates cross-chain auctions and token pools. The Polkastarter platform makes it easy for projects to raise capital from a decentralized, interoperable, Polkadot-based environment. The native POLS ERC-20 token has experienced incredible price action, as several projects launched on Polkastarter have seen significant success.
Exeedme- Launched on Polkastarter, Exeedme is a gaming platform designed to create new revenue streams for users of the platform. Exeedme harnesses the power of non-fungible tokens (NFTs) and decentralized finance (DeFi) to incentivize gamers to monetize their skills. This is achieved with the native XED token.
Akropolis- Akropolis is an autonomous, decentralized platform powered by Polkadot for building community economies. As one of the most innovative cross-chain decentralized finance (DeFi) protocols to-date, Akropolis facilitates under-collateralized borrowing and lending. This could be a complete changer for DeFi, as most DeFi lending protocols require over-collateralization to take out a loan."- https://academy.ivanontech.com/blog/top-polkadot-projects-2021-exploring-the-polkadot-ecosystem
