Frax (@Frax): Stablecoins Built to Last

Stablecoins Built to Last Last week reminded us of one of DeFi’s biggest problems: "stablecoins" that aren't stable. Stream's xUSD, a high-yield stablecoin combining on-chain plays with opaque off-chain strategies, collapsed due to poor risk management. This collapse was amplified by partner and curator incentives to integrate xUSD, leading to a cascade of losses across DeFi. The lessons are familiar: demand transparency and understand the risks of what you hold. Yet, we continue to repeat these mistakes because risks aren't disclosed, and incentives favor profit over safety. At Frax, transparency and stability are non-negotiable. We approach the stablecoin market with the only two products you'll ever need: frxUSD, our fully-backed digital dollar built for GENIUS, and sfrxUSD, our DeFi yield stablecoin. We built these stablecoins to last. TL;DR Stream xUSD promised double-digit APY with opaque off-chain strategies and blew up. Adoption surged as credible partner/curator integrations created a false sense of security. We need to demand transparency and be wary of outsourcing risk analysis to those with perverse incentives. There are two types of stablecoins: GENIUS-compliant digital dollars and yield stablecoins. Favor teams with a track record and guardrails over the highest APY. Stream xUSD and Bad Incentives Stream’s xUSD presented itself as a stablecoin earning impressively high “market-neutral” yields via “lending arbitrage, incentive farming, dynamically hedged HFT, and market making.” Some positions were visible on-chain, but as total value locked (TVL) climbed into the hundreds of millions, a growing share of activity moved into opaque, off-chain strategies. It was hard to ignore the headline APY, promising industry-leading returns. It wasn't just retail investors drawn in. Curators and product teams, motivated by growth and management fees, integrated xUSD to boost TVL and climb to the top of lending protocol dashboards sorted by APY returns. These reputable integrations created the illusion that thorough due diligence had been conducted and risks were contained. However, this was not the case. Stream revealed that an external fund manager lost $93 million, exposing the fragility of their operation and triggering the collapse of their house of cards. The Solution is Transparency Higher returns come with higher risks. The challenge lies in identifying these risks, especially as strategies shift off-chain. A yield stablecoin should clearly state that it is a strategy wrapper and disclose its venues, limits, and governing policies for allocations. Even when yield stablecoins publish their on-chain holdings, off-chain factors can still come into play. Users assume due diligence from partners. In the case of Stream, these curators and partners had a perverse incentive to overlook security issues in favor of profit. It's nearly impossible for the average user to assess the relative risk of default and make informed investment decisions with opaque yield stablecoins. This is why our industry must demand transparency and why we are excited about DeFi ratings agencies like @CredoraNetwork. Change won’t occur unless people build solutions. Two Types of Stablecoins With the passing of GENIUS, the stablecoin market is splitting into two distinct categories: GENIUS Stablecoins Digital dollars built to the GENIUS standard. These are payment-grade assets serving as on-chain money. They are 1:1 backed with verifiable assets that match liabilities, and are able to plug into traditional payment rails. Their job is stability and interoperability, not yield. Yield Stablecoins These are strategy wrappers. They seek higher net returns by allocating to on-chain and off-chain strategies of varying risks. Higher yield is correlated to higher risk. However, well-executed strategies can provide higher returns on a risk-adjusted basis. Ideally, yield stablecoins deliver risk-priced yield with bounded, explainable exposure. A yield coin is not defective because it can incur drawdowns; it is defective if the drawdowns are hidden until it is too late. This split is critical. Users need to know whether they hold money or a portfolio, and to judge each by the standards that fit its job. Frax implements this split intentionally. We operate frxUSD as money and sfrxUSD as a yield asset, designing each to meet its role. GENIUS Digital Dollar: frxUSD frxUSD is fully backed by bankruptcy-remote, tokenized U.S. Treasury funds. These funds are managed by financial leaders such as BlackRock, Superstate, and WisdomTree, with everything verifiable on our transparency dashboard. The goal of frxUSD is to function as on-chain cash and integrate into the payment system in a post-GENIUS world. This is the safest stablecoin you can hold, available on over 20 chains. Through FraxNet, you can mint or redeem frxUSD instantly from your bank account and earn rewards. We believe the market for GENIUS stablecoins is significantly larger than for yield stablecoins and we've built frxUSD as our flagship stablecoin to meet this demand. Safe Yield: sfrxUSD https://x.com/fraxfinance/status/1972779240983793820?s=20 sfrxUSD is designed to provide the highest risk-adjusted yield on stablecoins. It allocates to blue chip yield strategies and routinely outperforms top yield stablecoins. sfrxUSD liabilities and assets are separate from frxUSD reserves. Like frxUSD, all backing can be verified in real-time on our balance sheet. We use whitelisted, blue-chip venues with caps. Governance has approved an initial set of venues, such as Curve pools and major lending markets like Aave, Euler, and Fraxlend. There are defined integrations, for example, specific Ethena or Pendle deployments, each with explicit dollar caps. These caps manage risk in advance and encourage diversification across venues. External backing proposals start small and only scale after demonstrating performance and risk discipline. This approach avoids chasing temporary incentives and protects holders. Allocations must meet a time-weighted yield threshold above the current sfrxUSD APY. This discourages subsidizing venues merely to inflate numbers and reduces APY manipulation. While curators put their profits on the line, we stake our entire reputation on these products. As a result, you won’t see double-digit APRs on sfrxUSD when the risk isn’t justifiable. We’ve been building in DeFi for many years and intend for these products to last for centuries. Stablecoins Built to Last The xUSD unwind did not reveal a new category of risk, it highlighted existing ones: recursive looping, hidden leverage, and incentive structures that pushed risk beyond users' visibility. A digital dollar should outright reject these trade-offs. A yield stablecoin should manage them transparently, with strict limits. This is how we built frxUSD and sfrxUSD. As a user, you must first understand the type of stablecoin you are holding. If it's meant to function as money, hold it to the same standard as money. If it's meant to provide yield, expect risk that's priced and bounded. Understand where the assets reside, which venues are allowed, how much can be allocated, the frequency of reporting updates, and its ability to perform under stress. Favor transparent systems with a track record of stability. Be very cautious of yields that seem too good to be true without solid evidence. Every cycle, the market will continue to tempt people with the promise of high-yield "stablecoins." By definition, returns higher than risk-free rates come with higher risks. To be taken seriously as an industry, we need to demand transparency and accountability and build products that last.
