Yield Stripping for Tokenized Equities
income token + price token = yield stripping
Splitting xStocks into income and price exposure -- two tokens, two markets, one vault.
01 -- The Problem
Tokenized equities bundle two types of value into one token
- -A day trader holding xSPY for 6 hours is paying for a dividend they will never collect.
- -An income investor holding xSPY is absorbing price volatility they do not want.
- -DeFi has no fixed-income primitive for equity yield -- the largest yield market in the world ($3T+ securities lending, $500B+ dividend market) has no onchain equivalent.
- -Existing lending protocols ignore dividend mechanics entirely -- rebases during borrows are unhandled and exploitable.
- +xStocks are underleveraged as a DeFi primitive. Their two core value components -- yield and price -- have never been separated.
02 -- The Solution
Split. Trade. Arbitrage.
Deposit xSPY
into the vault
Mint xdSPY + xpSPY
income + price tokens
Trade each leg
on dedicated markets
xStream splits xStocks into a xdSPY (dividend token) and a xpSPY (price token), then builds a 24/7 income market and an intraday leveraged trading market around each -- connected by an arbitrage mechanism that keeps both tokens honestly priced.

Burn both, get xSPY
03 -- What Makes This Different
Three things that don't exist anywhere in DeFi today
01
Yield stripping on real equity dividends
Pendle does DeFi protocol yield -- variable, opaque, crypto-correlated. xStream does corporate dividends -- predictable, quarterly, backed by real earnings.
02
xpSPY as an active trading instrument
In Pendle, the principal token is a boring zero-coupon bond. xpSPY is pure equity price exposure designed for leveraged intraday trading.
03
Market-hours forced settlement
xStocks prices freeze at market close. This makes xpSPY settlement provably fair -- no after-hours manipulation, no overnight liquidation risk.
In Pendle, only the yield token is exciting. In xStream, both tokens serve massive existing markets -- income investors and leveraged day traders.
04 -- How It Works
Three contracts, two markets, one arbitrage anchor
- Vault: Deposit xSPY, mint xdSPY + xpSPY at 1:1. When xSPY balance increases on dividend, 100% is attributed to xdSPY holders atomically.
- Income Market (24/7): AMM pool xdSPY/USDC. Price accrues toward dividend date, spikes at rebase, resets. No oracle needed.
- Day Trading (Market Hours): Session 9:30-4:00 EST. Post USDC collateral, 3-5x SPY leverage. At 4PM: P&L settled, xpSPY returns, fees go to xdSPY holders.
- Arbitrage Anchor: xdSPY + xpSPY always redeemable for xSPY. Hard price ceiling and floor enforced by self-interest -- no oracle needed.
05 -- Viability and Uptake
The demand already exists
daily notional in SPY options + E-mini futures
For income investors
SPY base dividend: ~1.3% annually. xpSPY session fees at 30% utilization: ~10-15% annually.
12-16% APY
Real yield backed by S&P 500 corporate earnings -- not token emissions.
For day traders
SPY options: $400B+ daily notional. E-mini futures: $200B+ daily. These users already trade intraday SPY exposure.
$600B+
daily notional in existing SPY trading markets.
Cold start solved
Two-sided market with aligned incentives from day one. Recombination arbitrage ensures price efficiency without seeded liquidity.
06 -- Impact for xStocks
The most composable RWA primitive in DeFi
Rebase is load-bearing
Without onchain dividend rebasing, yield stripping cannot work. xStocks are the only asset that makes this possible.
Market hours are load-bearing
Without price freeze at market close, forced intraday settlement is unfair and manipulatable.
First fixed-income primitive
Unlocks institutional and treasury demand that currently has nowhere to go in the xStocks ecosystem.
Every xStock compatible
Any new xStock asset (xAAPL, xTSLA, xQQQ) is immediately compatible with the vault architecture.
xStream proves that xStocks infrastructure unlocks entirely new financial markets, not just a blockchain wrapper on existing ones.
07 -- Judging Criteria Alignment
How xStream maps to what matters
xStocks Relevance
Rebase + market hours are structurally required -- not bolt-on
Technical Execution
Vault, two AMMs, keeper, rebase interception, live demo
Innovation
First yield stripping on real equity dividends in DeFi
UX & Design
Two clean user journeys -- staker and trader, no overlap
Market Potential
Addresses $400B+ daily SPY trading + dividend income market
