DeFi
Acala Network
Acala is building a sustainable liquidity layer for Web3 finance that automatically captures returns, aiming to become the HyFi (DeFi+CeFi) infrastructure for crypto and real-world assets. Acala's multi-chain asset center UAH (Universal Asset Hub) provides multi-chain liquidity staking (LST) protocols such as LDOT and synthetic assets tDOT (DOT-LDOT), AMM, and highly compatible and customizable EVM+ (based on Substrate). The security of the Acala network is supported by the Polkadot relay chain and is also a liquidity gateway for Polkadot parachains and L1/L2 blockchains.

Bifrost
Bifrost (Rainbow Bridge) is the basic DeFi protocol of the Polkadot ecosystem. It is committed to becoming an infrastructure that provides liquidity for pledged assets and is a member of the Substrate Builders Program and Web3 Bootcamp. Its token can optimize transactions in multiple scenarios, serve as a transfer channel for pledged rights, and achieve risk hedging of pledged assets.

Smart Contracts
Moonbeam Network
Moonbeam is a developer-friendly blockchain that is fully EVM-compatible, Web3 API-compatible, and a bridge that connects Moonbeam to the existing Ethereum network. With Moonbeam, developers can easily achieve cross-chain compatibility using existing Ethereum developer tools and networks. Developers can easily deploy existing Solidity smart contracts and DApp front-ends to Moonbeam with only minor modifications based on their own development results.
