Where real yield begins.
Solstice’s YieldVault is engineered for returns in any market cycle. Advanced delta-neutral yield strategies are available fully permissionlessly. By locking USX into the YieldVault, users receive eUSX, a liquid staking token that represents their share of the yield-generating pool.
YieldVault only requires you to lock your USX up for a minimum of 7 days to start receiving real yields on your stablecoins.
YieldVault
How it works.
01.
YieldVault
Lock & receive eUSX.
Lock your USX in the YieldVault to mint eUSX, your tokenized claim on the vault and its yield.
02.
YieldVault
Earn yield.
Over time, the YieldVault receives rewards (in USX), resulting in increased value of the eUSX (in USX). eUSX appreciates in value as yield is distributed into the program vault.
03.
YieldVault
Unlock & withdraw anytime.
When you're ready, return eUSX then burned to the vault to unlock your USX, plus any accrued yield.

Frequently Asked Questions
Solstice’s YieldVault protocol brings institutional-grade crypto yields to everyone powered by locking USX for eUSX (a liquid staking token) to access transparent, battle-tested delta-neutral yield generating strategies.
Yield is generated through a dynamic blend of delta-neutral strategies including funding rate arbitrage and hedged staking alongside a portion in tokenized treasury allocations. No magic, no degen risk - smart, risk-balanced returns.
Solstice’s team has been running the strategy behind the YieldVault for three years with a trailing 12 month return of 11.8% and a 21.5% ann. return in 2024. Yield fluctuates depending on market conditions, but we focus on stable, transparent, and sustainable yield-generating strategies. The team has navigated all crypto crashes since 2020 including but not limited to FTX, USDC de-peg, exchange hacks, 3 Arrows/Terra Luna, and more, suffering zero principal loss in each of those respective months and having gone through zero hacks or exploits.
Solstice is specifically designed to scale to billions in TVL through our institutional-grade infrastructure and operations. Solstice spreads capital across multiple exchanges and trades a wide range of delta-neutral pairs, the strategy itself is built to capture alpha at scale. Solana's speed and Solstice's design enables efficient onchain yield for all of its users.
The exchange rate between USX and eUSX updates periodically based on the rewards dripped into the YieldVault. It reflects the underlying yield performance and is calculated at the time of locking/unlocking.
There is a 7-day cooldown from the YieldVault before you can access your USX returns. This ensures liquidity stability and aligns with how capital is managed across venues.
Once you initiate a redemption from the YieldVault, your eUSX is burned and your USX enters a cooldown period before it becomes withdrawable. During this cooldown window, you will no longer receive any yield or rewards. This mechanism ensures fairness by preventing users from exiting mid-epoch while still collecting rewards.
Yes, partial redemption is supported. When you initiate a partial redemption, a cooldown starts. If you initiate a partial redemption again during the cool-down window, the cool-down period is restarted.
