Tokenizedstocksthat earn.
Prism is the prime broker for Binance bStocks on BNB Smart Chain. One deposit, refracted into five yield streams: earnings volatility, in-kind lending interest, options premiums, basket exposure and a fixed share of every fee the protocol collects.
Markets
Six tokenized stocks.
Three ways to earn each.
Products
Three flagship surfaces.
Earnings vault
Capture the IV crush, four times a year.
Deposit Nvidia or Tesla tokenized. The vault sells volatility before earnings and profits when the stock lands inside the implied move. When it gaps beyond it the vault takes the loss (NVDA closed +24% after May 2023 earnings). Short vol, not a savings account.
Lending
Supply a stock. Earn the same stock.
Six isolated pools, one per supported bStock. Suppliers earn in-kind from borrowers. No oracle exchange-rate drift, no stable middleman.
Stake
One stake. Three protocol fee streams.
Every fee splits 33% buyback, 33% pINDEX donation, 34% Merkle drop, all three converge on sPRSM. One position captures all three.
The problems
Three things are wrong with
tokenized stocks today.
bStocks sit idle
Binance shipped six tokenized stocks. There is no native DeFi layer to put them to work, they sit in wallets earning nothing.
Brokers can freeze you
Robinhood paused buying during GameStop. Centralized venues control your access. You lose your edge at the moment you need it most.
DeFi only knows stablecoins
Aave-style lending, Pendle splitting, options vaults, every primitive in DeFi today is wired around stablecoins, not the equity itself.
What we innovate
Six pieces of contract code
that didn’t exist before Prism.
Split-invariant options
Option strikes are denominated in raw token, not USD. When Binance fires a stock split, the BEP-8056 multiplier flows through every quote, existing positions auto-adjust. No migration scripts, no broken strikes.
PT / YT for equities
Lock fixed yield on Nvidia (PT) or bet aggressively on its dividend and split upside (YT). Pendle did this for staked ETH; we do it for the six tokenized stocks Binance issues, multiplier-aware.
On-chain Black-Scholes
A 165-line Solidity library: ln, exp, normCDF (Abramowitz-Stegun), put-call parity. Every option quote on Prism is priced by fair-value math on-chain. No off-chain matcher, no orderbook to censor.
Cross-margin under one NFT
Your entire portfolio is an ERC-721. Multi-collateral, multi-debt, one health factor. Long six stocks + short one, the legs hedge each other. Capital-efficient by construction.
The IV-crush vault
No other DeFi protocol offers earnings-vol vaults on tokenized equities. The strategy runs 24 times a year across the six bStocks, direction-neutral and calendar-driven, with the loss profile of short volatility: many small wins, occasional large losses when a stock gaps past its implied move.
Permanent 33% buyback
FeeRouter swaps a third of every protocol fee batch to PRSM and deposits into sPRSM. No admin can disable it. More usage → more buy pressure → more sPRSM share-price growth. Closed loop.
The equity-native layer · code complete, deploying next
Stocks sleep 128 hours a week. Money markets never noticed.
Prism is the only lending protocol designed for assets that sleep.
A money market that reads the corporate calendar.
A stock’s risk isn’t constant, it spikes on schedule: earnings four times a year, ex-dividend dates, weekends with the underlying closed. Prism’s risk engine reads an on-chain, economically disputable calendar and breathes with it: LTVs ramp down into every earnings window and restore after, borrow rates carry an event premium, weekend haircuts apply before Friday’s close and lift before Monday’s open. Every generic money market treats the night before earnings like any Tuesday. Prism doesn’t.
Hard-to-borrow auctions
Scarcity priced by the market, not by a curve.
GapShield, earnings insurance
Gap past your line, get paid.
SBLOC on-chain
Your portfolio pays its own debt.
Leveraged equity tokens
2× exposure that respects the calendar.
All five primitives are code-complete and tested in the public repo, pre-deployment. Addresses will appear on the contracts page the day they ship, no claim without a BscScan link.
How it works
From a deposit to a
compounding share price.
Deposit any bStock
Hold NVDAB, TSLAB, CRCLB, MUB, SNDKB or SPCXB in your wallet. Approve once. Deposit takes one signature.
The protocol runs
The vault LPs into the options pool. A calendar bot bumps IV pre-earnings, resets post. Lending interest compounds in the background.
Withdraw, any time
Your vault shares are worth more than what you deposited. Burn shares, receive your stock back, plus the spread captured. No cooldown.
Launch
Your stocks
should pay you.
Connect a wallet, deposit a bStock, walk away. Three minutes from zero, then the protocol runs forever.
