Vitalik Buterin recently published this post: Building index-tracking assets on top of options instead of debt ( It lands almost exactly on what we are building. It helps to start with what
@VitalikButerin is actually trying to achieve.
His post is really about an old, hard problem: how do you build price-stable and index-tracking assets on-chain without trusting a central issuer? You want to give people exposure to something like the dollar using only a trustless asset, such as ETH, as backing. Every design like this has two sides. For everyone who is long, someone has to be short, and if the price moves far enough against the short side, the shorts go broke. The usual fix is liquidation: the system force-closes that position before the loss eats through the collateral.
That fix is the real problem. To liquidate the moment a price is crossed, you need a feed that is fast and always right. As Vitalik puts it, "Real-time oracles are very hard to make safe." A fast feed cannot pause to be double-checked, and it is the easiest part of the system to attack. It is where a long line of collateral-backed stablecoins and lending markets have broken.
His move is to change the building block from debt to options. He splits one unit of collateral into two complementary claims, which he calls P and N. P is the protected side, the one that behaves like the thing you actually want to hold, such as the dollar. N is the risk side that takes the other end of the trade. The two are built so that they always add back to the whole unit of collateral. Because P and N always sum to the collateral, no position can end up underwater, so there is nothing to force-close. Take away the liquidation, and the fragile real-time oracle goes with it. Settlement can be slow, and slow is safe.
This incidentally is the same design architecture as our SMART Tokens. We do the same split. Deposit one asset, starting with BTC and ETH, and it becomes two tokens. RiskOFF is the calmer half: it gives up some upside in exchange for a floor under its losses. RiskON is the other half: it takes that downside and, in return, earns the extra upside. Put the two back together at any time, and you have your asset back. No loan, no margin, nothing to rescue.
But here is where we differ. Vitalik favors a slow oracle, and to minimize increased exposure to the underlying as price ticks down, suggests that users independently rebalance prior to maturity. He acknowledges that such a design choice likely imposes potentially significant rebalancing costs that could potentially make the mechanism unworkable. We took a different tack. We favored abstracting the mechanics so that the product is something an ordinary user can simply hold and trade. We run it in repeating periods, called epochs, that reset on their own, with a safety barrier that ends a period early in a sharp crash, before the risk-taking side can fall below zero. That barrier is the trade-off: because it has to watch the price as it moves, our version leans on the oracle more than Vitalik's read-it-once design. We give up a little of that purity on purpose to achieve that abstraction. And in the process we solve for the rollover cost that Vitalik left unresolved. At the end of an epoch, users get automatically rolled over into a new epoch that resets the options at zero cost (the options are designed to be a costless collar).
Our bounded, fully collateralized options turn risk into something you can safely hold, trade, and price. That is the piece DeFi has been missing. When the most credible architect in crypto independently arrives at the same thesis we have been working on, it tells us we are on the right track.
RiskON and RiskOFF are only the beginning of what this design can do. We call the mechanism SMART, a Split Mechanism for Asset Risk-Tokenization, and the same split can produce a whole family of risk tokens: long-volatility and short-volatility tokens for trading swings directly, 10X Bull and -10X Bear tokens that give amplified exposure with no margin calls and no liquidations, yield-generating tokens, and tokens built for tail risk, across more assets over time. One mechanism, many shapes of risk…
