OIN is a decentralized stablecoin issuing and trading platform. Unlike MakerDao's mechanism of issuing a single staboin Dai using mainstream assets as collateral, OIN focuses on issuing its own synthetic staboins for different project parties. Personalized staboins allow projects to quickly join the Defi ecosystem, for example for intra-ecosystem payments, exchange with mainstream staboins, leveraged transactions, etc. The OIN platform is initially based on Ethereum, and will gradually expand to popular public chains such as Polkadot, Avalanche, and Near, and eventually become a cross-chain stablecoin issuing and trading platform.

OIN is described as the first DeFi platform to offer liquidity mining and lending on ontology, and eventually on other top platforms with cross-chain capabilities. The platform will build bridge technology that seamlessly integrates Ethereum into its ecosystem, open to all current DeFi Spaces. Cross-chain technology is critical to DeFi and its growth as a legitimate financial infrastructure, after all, traditional finance also integrates the entire world, its currencies and different financial systems.
