invUSD is a USD-pegged stablecoin developed within the Monolith infrastructure framework by Inverse Finance. The token is designed for use within decentralised finance applications including lending markets, decentralised exchanges, liquidity pools, collateralisation systems, treasury operations, and other Ethereum-compatible financial applications. Monolith provides the infrastructure supporting invUSD and related stablecoin systems through smart contract-based architecture intended for integration across the broader decentralised finance ecosystem. invUSD is a USD-pegged stablecoin launched through Monolith, a permissionless stablecoin-as-a-service protocol developed within the Inverse Finance ecosystem. Monolith allows anyone to deploy an over-collateralized and immutable stablecoin on Ethereum using standardised smart contract infrastructure designed for decentralised finance applications. Each stablecoin deployed through Monolith operates as an isolated system with its own ERC-20 Coin contract, ERC-4626 staking Vault, and Lender contract, while sharing audited protocol infrastructure including Factory, Lens, Metadata, and InterestModel components. The protocol uses a dual-debt model consisting of redeemable 0% debt and interest-bearing non-redeemable debt. Monolith also includes an autonomous interest rate controller designed to support peg stability. Stablecoins deployed through the framework become fully immutable four years after deployment.
