Robinhood Stock Tokens can't be minted on weekends or US holidays (about 31% of the year), but they keep trading onchain. Thin new listings spike: HIMS ran more than 300% above its Friday price on 29 Aug. Offmint is session-gated liquidity: a vault that places a four-step sell ladder above the reference price only while minting is off, and buys back after reopen with a price cap. Plus a live monitor, a weekend report of every past spike, and a personal sell order from your own wallet.
