Bringing Institutional Grade DeFi to Solana

Watch on YouTube

Insightful discussion at Breakpoint 2025 with Ben in Abu Dhabi. We went deep in USX, eUSX, and the upcoming SLX TGE, scheduled to happen in Q2 of 2026.

Key takeaways

  • Ben Nadareski moved from physics labs to Wall Street derivatives trading, then spent a decade in institutional crypto before founding Solstice out of Deus X Capital.
  • USX is an overcollateralized synthetic stablecoin backed by USDC and USDT, and Ben says it saw zero depeg and zero redemptions during the October 10 crash.
  • At recording time, USX had grown to about $330 million in TVL since its September 30 launch and was the largest Solana-native stablecoin.
  • eUSX holders earn yield from a three-part delta-neutral strategy: funding arbitrage, hedged staking and tokenized treasuries.
  • Solstice had distributed more than $1.3 million in yield and reported 131,000 monthly active users.
  • Ben said Solstice would launch SLX at a conservative FDV, starting with a Legion pre-sale on the winter solstice, December 22.

Institutional-grade yield with permissionless access

Recorded on day three of Solana Breakpoint 2025 in Abu Dhabi, this is Hodl Up's first conversation with Ben Nadareski, CEO of Solstice. It took place weeks before the SLX token launch that the hosts revisited in Part 2 at Proof of Talk.

Ben's pitch is institutional DeFi with open access. "Whether you have $5 or $50 million, you get access to the same level of institutional-grade yield." The conversation covers his background, the three types of stablecoins, how USX and eUSX work, Solstice's stress test during the market downturn and the thinking behind its TGE.

From physics to institutional crypto

Ben started working in physics laboratories at 15, then applied that knowledge to execution trading on Wall Street. "You're a slow computer, that's all you are," he said of the role. He entered crypto around 2013 and worked at R3, ConsenSys, SIX Digital Exchange, Galaxy Digital and Deus X Capital before founding Solstice.

Physics taught him to see how parts fit together. He applies that to Solana partnerships, where institutional frameworks sit under the hood while the front end stays simple. He also delivered a pointed critique: "Over 50% of projects right now are building glorified back offices for TradFi." Crypto, he said, should deliver permissionless products, data sovereignty and equal access.

USX and the three types of stablecoins

How USX fits in

Ben split stablecoins into three models. The table below compares them as he described them.

ModelBackingExample
Fiat-backedDollars or treasuries held in banksUSDC, USDT
SyntheticOther trusted stablecoins as collateralSolstice USX
Asset-backed, hedgedCrypto assets such as BTC or ETH, hedged for neutral exposureEthena USDe

USX uses USDC and USDT as collateral, which Ben said gives crypto users deeper composability. It is overcollateralized, with insurance for liquidity events. During the October 10 crash, he said, USX saw "zero depeg, zero ADL exposure, zero redemptions."

He urged users to demand proof. "If they're not showing you real-time, third-party-audited proof of reserves, it's no longer 'trust me, bro.'"

Solana first

At recording time, USX was the fifth-largest stablecoin on Solana, 24th worldwide and the largest Solana-native stablecoin. Ben wants to integrate the full Solana stack, from payments and DEXs to lending and PT/YT markets, before expanding cross-chain. Teams that spread too early, he said, see utility erode.

How eUSX earns yield

USX holders can lock their stablecoins into a one-click yield vault to receive eUSX. Deposits are held with custodians Ceffu and Copper and mirrored onto centralized exchanges, where Solstice runs three strategies: funding arbitrage between spot and perpetuals, hedged staking and tokenized treasury allocation.

When spot markets fell about 20%, Ben said eUSX still produced 5 to 6% APY by shifting toward staking and treasury yield. "We won't have the sexiest yield, but we can shift into what's effectively a floor around treasuries no matter what." He urged users to question competitors posting high yields when funding rates are low.

Planning a better TGE

Ben laid out what a credible token launch needs: a regulation-minded pre-sale partner, careful exchange listings and a valuation backed by real numbers. Solstice chose Legion for its pre-sale. He cited seven figures of ARR, $1.3 million in distributed yield, 131,000 monthly active users and 15% yield over 12 months as the basis for pricing.

"The biggest issue with TGEs is an overinflated FDV," he said, noting some 2025 launches came in at 10 to 15x premiums. Solstice planned a conservative FDV and steady growth.

SLX was designed to incentivize USX use across payments, DEX pools, Exponent and lending markets like Kamino and Loopscale, and to let holders vote on new yield strategies. At the time, the Flares points program rewarded users for holding USX and eUSX ahead of the TGE. Deus X Capital, a $1.5 billion asset manager, funds Solstice and sponsors F1 driver Ollie Bearman, which put the Solstice logo on his helmet in Abu Dhabi.

FAQ

Frequently asked questions

What is USX by Solstice?

USX is a synthetic stablecoin on Solana, backed by USDC and USDT and overcollateralized with insurance for liquidity events. CEO Ben Nadareski says it saw no depeg or redemptions during the October 10 crash and became the largest Solana-native stablecoin.

How does eUSX earn yield?

eUSX earns yield from a three-part delta-neutral strategy: funding arbitrage between spot and perpetual markets, hedged staking and tokenized treasury allocation. Solstice shifts between them as conditions change, which kept yields positive when spot prices fell about 20%.

What are the three types of stablecoins?

The three main models are fiat-backed stablecoins like USDC, synthetic stablecoins backed by other stablecoins like Solstice's USX, and asset-backed stablecoins like Ethena's USDe, which hold hedged crypto assets to maintain a neutral position.

How can you tell if a token launch is overvalued?

Solstice CEO Ben Nadareski suggests checking three things: whether the pre-sale partner follows regulatory requirements, whether the project has real on-chain users and revenue, and whether its FDV is justified by those numbers rather than hype.
