OIN is a decentralized stable currency issuance and trading platform. Different from MakerDao's mechanism of issuing a single stable currency Dai using mainstream assets as collateral, OIN is committed to issuing its own synthetic stable currency for different project parties. Personalized stablecoins can enable projects to quickly join the Defi ecosystem, such as payment within the ecosystem, exchange with mainstream stablecoins, leveraged transactions, etc. The OIN platform was originally based on Ethereum, and will gradually expand to popular public chains such as Polkadot, Avalanche, and Near, and eventually become a cross-chain stable currency issuance and trading platform.
