CompliFi is a derivatives issuance protocol on Ethereum with minimal governance, no counterparty risk, no margin calls or liquidations, and limited sensitivity to blockchain congestion. Holding a derivative carries two major risks – loss of value if the market moves against you, and inability to collect your full payoff if the market moves in your favour. CompliFi takes away the latter risk. CompliFi creates a derivative by taking a fixed pool of collateral and issuing equal quantities of two derivative assets that together always have a claim on the entire pool. The first (“primary”) asset is the chosen derivative and second (“complement”) asset represents the opposite side of the trade. In other words, if you combine one unit of the primary asset with one unit of its complement, their respective risks cancel each other out - they can be exchanged back for a predetermined amount of collateral at any time. The desired payoff profile is induced by redistributing the fixed amount of collateral between the two asset classes, depending on the change in value(s) of the instrument’s underlying variable(s). Payoff function of the primary asset is defined directly by the behaviour we want to achieve, while that of the complement asset is defined by its claim on the residual collateral after the primary asset has been paid off. For instance, if the primary asset is defined as synthetic BTC, a rise in price of BTC on external markets would result in the same percentage increase in the primary asset's share of collateral. The complement asset would, correspondingly, decline in value, since its share of collateral always equal 100% minus the share of the primary asset. In other words, CompliFi redefines derivative payoff functions to fit within the confines of a fixed collateral pool - default is not possible by definition. This results in all instruments having an upper bound on their potential returns, reached when 100% of collateral has been redistributed in their favour. In practice, this does not result in significant limitations - the protocol can be used to create almost any desired risk exposure. All ComliFi assets have a finite maturity - users are able to swap back into collateral at a pre-determined point in time. The assets are minted in the form of ERC20 tokens and are tradable on most limit order book protocols and automatic market makers.
