Real yield on the S&P 500
The best place to hold the index onchain.
Pegged to SPY, not to a dollar. 24/7, on Robinhood Chain.
The business
Depth is the business
mTOMB is the base asset for RWA liquidity on Robinhood Chain, paired against SPY first, then against the rest of the stock tokens on the chain. Every pool makes tokenized equity trading deeper and cheaper, and every swap that routes through it pays the treasury. Most protocols rent liquidity. This one owns it and gets paid for providing it.
The hook
Attacking the peg pays for the peg
A Uniswap v4 hook prices every swap by direction. Away from the peg is expensive, back toward it is close to free, and the defense fee routes to the treasury rather than to LPs who will leave.
The Boardroom
A 401k with better hours
Stake mSHARE, earn the index return plus a share of every fee the protocol captures. It compounds, it runs around the clock, and it works in 120+ countries.
No brokerage account, no employer, no paperwork, no waiting until you are 59½.
Always an exit
No bonds. No recovery lottery.
Above the peg the protocol mints and sells into demand. Below it, the treasury buys back and the supply contracts. Once the treasury holds SPY, the Peg Stability Module will swap mTOMB for SPY one-for-one minus a fee, the fee being the revenue and the floor at once. It is dormant at launch, because a redemption promise with no reserve behind it is just a swap widget that reverts.

Everything below can cost you money
This section is the same size as the rest of the page on purpose. A protocol that hides its risks in six-point type at the bottom is telling you something.
Issuer risk
SPY is a tokenized debt security issued by Robinhood Assets (Jersey) Limited. The protocol is fully exposed to that issuer. If the issuer fails, the reserve fails with it.
Impermanent loss on non-SPY pairs
The SPY pair holds the same underlying on both sides, so it carries no directional risk. Every other stock-token pair does, and the treasury eats that loss.
Reserves compete with depth
Part of the reserve sits inside liquidity positions. Under stress, redemptions and pool depth draw on the same assets, and both cannot win.
Untaxed pools
Anyone can deploy a pool without the hook. Volume that routes around the protocol pays it nothing, and there is no way to prevent that.
Smart contract risk
The contracts are unaudited and undeployed. Seigniorage designs have failed repeatedly and publicly, and this one is not exempt from that history.
Regulatory restriction
Stock Tokens are not registered under US securities laws and are restricted in several jurisdictions. Nothing here is investment advice.
