sheaf

Sheaf goes where the stocks are.

Each chain is here for a reason about stocks. Solana has xStocks and the program. Robinhood Chain has the issuer's own stock tokens. Tempo has recurring payments the chain itself enforces, which is exactly what a monthly plan is. Hyperliquid prices stocks around the clock. Everywhere else the same contracts are portable, deployed and working, waiting for an issuer.

Running on Solana devnet and 5 EVM testnets, none on mainnet yet. Connect any EVM wallet on a basket page to get test tokens, create shares in kind, redeem them, or buy with dollars on the desk.

Solana devnet and 5 EVM testnets · every figure read from the chain when you open it

The same contracts, deployed unchanged where stock tokens are issued on mainnet but not yet on testnet. Each holds labeled mirrors, and every flow works from a wallet.

The same four rules, written natively on each chain

  • A recipe that cannot change

    Written once in the Basket constructor, with no setter, no owner, no pause and no upgrade path.

    components()

  • A vault only a redemption empties

    Nothing leaves except through a redemption, and deposits round up while payouts round down.

    vaultBalances() ≥ owed

  • Shares in kind, both ways

    Deposit the recipe and receive a share; burn a share and receive the recipe. No price is ever read.

    mint() · redeem()

  • A desk that turns dollars into shares

    A buyer escrows dollars; any participant who delivers the components collects them, and the shares go to the buyer.

Robinhood Chain

Robinhood's tokens, bound into one share

Robinhood's testnet faucet gives anyone five each of TSLA, AMZN, AMD, PLTR and NFLX a day. Those are the tokens the Robinhood baskets hold. Connect a wallet on a basket page and it reads what you already have, says how many shares that binds, and creates them in kind. Units are shown through each token's ERC-8056 multiplier, so a split never misstates a holding.

Tempo

A monthly plan is an access key

One passkey signature writes the plan on PlanDesk: the amount, the interval and the price cap. A second scopes the keeper to AlphaUSD.approve(PlanDesk) and PlanDesk.instalment. Ask for fewer shares and the plan answers FairOutOfBounds, run early and it answers TooSoon, call anything else and the chain answers CallNotAllowed. No custody, and gas paid in a dollar.

Deployed, verified, smoke-tested

New orders go to the v3 desks, deployed on October 9: a dollar desk that pays the 0.10% protocol fee to a separate treasury key the server does not hold, and PlanDeskV3, whose bounds trail each fill so a monthly plan keeps running after the market moves. Each chain ran the same end-to-end test on them: approvals, a dollar order and its fill, then a plan with two filled runs. The earlier desks are listed under the new ones; v2’s fee went to the house key.
