BFUSD

BFUSD is a yield-bearing dollar token issued within an exchange ecosystem. Exchange-issued yield products differ from protocol-based ones in a specific way: the counterparty is a company rather than a set of contracts you can read.

An exchange product is a company's obligation

With a DeFi protocol, collateral and rules are on-chain and inspectable. With an exchange product, the company holds the assets and its solvency is the risk. The 2022 failures of several centralised yield providers demonstrated exactly what that distinction means in practice.

Where exchange yield typically comes from

Funding rate capture on the exchange's own derivatives markets, lending to margin traders, or the exchange subsidising a rate to attract deposits. Each has a different persistence, and a subsidised rate is a marketing expense that ends when the marketing does.

Convenience is genuine and so is the concentration

For a user already holding assets on the exchange, earning yield without moving anything is frictionless. It also means both the asset and the yield depend on one company's solvency, regulatory position and commercial decisions.

The disclosure standard to expect

Any yield product should state its source, the conditions under which it falls, and whether the principal is at risk. Products that present only a rate have omitted everything a holder needs to evaluate it.

Who it suits

This fits users already operating on the exchange who understand the counterparty concentration. Users wanting on-chain verifiable backing should use a protocol-based alternative.
