Boros Revolutionizes Crypto Yield: Funding Rates Go Onchain as Tradable Assets
DeFi just got a new weapon in the yield wars. Boros Protocol is turning perpetual swap funding rates into tokenized yield instruments—bringing what was once opaque hedge fund terrain onto transparent blockchains.
Game Theory Meets Onchain Liquidity
By packaging funding rate cash flows as ERC-20 tokens, Boros lets traders go long or short on the most controversial metric in crypto derivatives. No more begging CEXs for historical data—every basis point fluctuation gets memorialized onchain.
The Fine Print
Early tests show arbitrageurs already front-running the tokens against CEX funding rate announcements. Because if there's one thing crypto loves more than decentralization, it's free money left on the table.
Wall Street's worst kept secret—that half of 'sophisticated' yield strategies just chase funding rates—just got a public blockchain autopsy. The suits won't like that.
Complementary to Ethena
Once Boros expands to other exchanges where Ethena hedges its spot longs, Boros should provide ample benefits:
Pendle founder TN Lee expects Boros will eventually harmonize funding rate markets, which are quite variable today:
“Boros allows [arbitrage] of funding rates across exchanges, thereby resulting in the converging of rates,” Lee told Blockworks.
The utility goes further, however. As the Boros team writes: “Beyond the obvious utility to cash and carry traders, the mechanics we are bringing to life open up a new vertical for all assets with yield, regardless if they are on-chain or off.” The model can extend to staking, real-world credit, or even CeFi borrow/lend rates — basically anything for which there is an oracle-verifiable yield source.
To support this new interest-rate layer, Boros will open up dedicated vaults that earn fees and boosted incentives by providing liquidity to fixed/floating funding rate swaps. These vaults mirror Pendle’s V2 pools, allowing LPs to take the other side of directional hedging demand and earn a share of the new market’s fee flow.
Tokenize everything
Boros isn’t the only project racing to turn yield-bearing positions into “spendable” collateral. Notional’s forthcoming Exponent upgrade takes a strikingly similar tack: it “tokenizes new yield strategies specifically designed for Leveraged yield users” and then lets those tokens be pledged on deep-liquidity lending rails such as Morpho.
Exponent’s headline innovation, Smart Redemption, lets a vault holder redeem a staked asset (e.g., sUSDe for USDe) without first withdrawing collateral from the lending market, enabling costless exits and, crucially, making yield tokens with lock-ups or thin secondary liquidity acceptable to risk engines.
Functionally, the two designs rhyme: both Boros and Notional Exponent wrap a variable cash-flow into a token whose value can be reliably marked by onchain oracles and tracked to maturity, giving risk engines a clear path to whitelist it as collateral. Even though a YU’s market value simply decays toward zero at expiry, the predictable oracle feed and known payoff window still let lending markets haircut it with confidence.
The upshot is the same capital-efficiency fly-wheel: Users can lever against the very stream of income that services their debt, while money-markets gain a diversified pool of “income-backed” collateral that is less correlated to spot swings. Together, Boros and Exponent point to a DeFi future where yield primitives are the Core building blocks of credit, shrinking idle capital and smoothing the path to leveraged, yet risk-managed, strategies across the stack.
Importantly, Boros does not launch a new token. Instead, 80% of its fees will accrue to vePENDLE holders, continuing Pendle’s model of rewarding long-term stakers. At the same time, Pendle emissions will be used to bootstrap Boros vaults. That’s also a potential source of sell pressure, but one that is likely to recycle back into vePENDLE locks as yields increase. The token’s fundamentals benefit from the added fee stream without unnecessary dilution — a design choice that deserves credit, especially in a time when many founders opt to spin off products with one or more new tokens.
Starting over
Still, the launch is not without complexity. Boros is “starting from 0 again,” the team admits, with its own risk engine and vault logic.
“As a new platform being built to stand alongside Pendle V2,” the team notes, “risk management will be our main focus at the initial stages — especially at the start when new mechanics and market dynamics are being experimented with.”
Among those dynamics: a new type of price-volatility feedback loop. Today, a sudden 1,000 bips spike in funding can force traders to unwind spot-perp basis trades just to stop the bleeding— creating a cascade of liquidations and market stress. But with Boros, those players can hedge the funding leg without closing directional exposure. If liquidity is deep, YU markets could act like interest-rate swaps in TradFi: dampening volatility and compressing extreme funding prints.
That “if” is crucial. Hedging only works if the YU orderbook is liquid enough not to introduce slippage or risk of blowouts. To mitigate early reflexivity, Boros is limiting open interest to 1.2x the perp OI — tight by design. If liquidity grows, the ability to hedge funding cheaply should mute the sharpest funding swings and, indirectly, some price volatility.
Boros doesn’t just tokenize a new yield source, but has the potential for this new funding-rate derivatives layer to be integrated into many other DeFi applications: money-markets, structured products, delta-neutral strategies, and, ultimately, real-world credit.
But the larger change is architectural: As these products show, any stream of yield can now become both a trading instrument and first-class collateral, pushing DeFi a step closer to a full-stack fixed-income market onchain.
