The DeFi mullet in action. SparkLend's best-in-class liquidity and borrow rates are now available to GOFR users on Galaxy.
Galaxy bought $100M of sUSDS and approved it as collateral across our institutional lending book. It's the latest step in a deepening relationship with @SkyEcosystem — from Grove's $500M warehouse facility to Spark-backed financing for GOFR.

USDS is moving towards becoming the main liquidity hub for stablecoins and USD-denominated RWAs. Basin is a key part of that. Congrats to our friends at Grove!
Grove Basin JTRSY now holds $50M in stablecoin liquidity. Larger redemptions can now clear in a single transaction. Available to JTRSY holders on @centrifuge. Basin is filling. Tap in.

All things will be tokenized and stablecoins are driving this.
Stablecoins are the forcing function. Liquidity attracts liquidity. @hexonaut, CEO and Co-Founder of @sparkfinance, on why a large stablecoin base doesn't stay a stablecoin base; it drives tokenization of equities, commodities, and the rest, once everyone's settling on the same global ledger.

On today's Vibestream at 12pm ET, we're getting into the weeds on institutional crypto lending with Sam MacPherson (@hexonaut) of @sparkfinance, Anchorage Digital's Head of Atlas @maceyaj and Global Head of Revenue Justin Brill. This is going to be good.
On tomorrow's episode of the Vibestream: Anchorage Digital and @sparkfinance are working together so institutions can borrow through Spark's lending book while collateral stays in qualified custody. Dive into the new blueprint for institutional DeFi with Sam MacPherson (@hexonaut), Co-Founder and CEO at @sparkfinance, Anchorage Digital's Head of Atlas @maceyaj, and Global Head of Revenue Justin Brill.

Excited to have Galaxy join the Sky ecosystem!
Galaxy Adds $100 Million in sUSDS to Corporate Treasury and Acquires SKY Galaxy Digital has purchased $100 million of Sky Protocol’s yield-bearing stablecoin sUSDS using its own balance sheet and approved it as collateral across its institutional trading business, which has a $1.4 billion average loan book and serves more than 1,600 counterparties. Clients can continue earning the Sky Savings Rate on their full sUSDS positions while using them as loan collateral. Galaxy also acquired an undisclosed amount of SKY, while the two firms are discussing an expansion of their existing $500 million warehouse facility.

The Stablecoin FX Layer has now passed 14b in total volume. USDC, USDT, PYUSD, and RLUSD all have deep on-chain liquidity via USDS on Uniswap.
🚨 EXCLUSIVE: Spark’s stablecoin FX Layer has surpassed $12 billion in volume in under three months, with Ripple’s RLUSD now joining through a $375 million deployment. @hexonaut, co-founder and CEO of Spark, told AlphaWire the growth is being driven primarily by treasury capital rather than short-term “mercenary” liquidity chasing incentives. RLUSD’s $375M deployment is being split across three areas: • $250M for institutional capital deployment • $50M for RLUSD/USDS liquidity on Uniswap v4 • $100M to seed an RLUSD lending market on SparkLend MacPherson says the goal is to give stablecoins shared infrastructure across liquidity, capital allocation and credit instead of forcing each ecosystem to build everything from scratch. RLUSD/USDS alone traded more than $600M in its first week. alphawire.xyz/news/stablecoi…

Thanks to @FINTECHTVglobal for having me on again!
Tokenization is going to "consume the entire financial industry eventually." @hexonaut, CEO of @sparkfinance, tells @RemyBlaireNews tokenized equity is the next step after stablecoins, with $HOOD and $COIN already launching it onchain, opening new lending and financing opportunities.

I tracked 98 ETH whales for six months. Their direct wallet holdings fell 19.2%—but that does not mean 19.2% was sold. Here’s where 1.37M ETH went across exchanges, staking, Sky, SparkLend, and Aave.

Where Did 1.37 Million ETH Go? What Six Months of Whale Flows Reveal About the ETH Market

We tracked 98 whales that directly held an average of at least 40,000 ETH equivalent in February 2026. Their wallet holdings of ETH, WETH, and major liquid staking and restaking tokens fell from

SparkLend growing rapidly.
SparkLend's borrowing on Ethereum has grown 247% since March, approaching $3B. USDS led the growth. USDS borrowing rose from $188M to $917M, accounting for nearly half the $1.5B increase in total borrowing. Competitive borrowing rates are helping drive that demand. Over the last 30 days, USDS borrowing averaged 3.9%, while USDT averaged 4.07% and USDC 4.3%, all below comparable rates across other major pooled lending markets. USDS also gives borrowers another advantage: through @SkyEcosystem's LitePSM, borrowed USDS can be converted into USDC while the debt remains denominated in USDS. We've seen it used to refinance across lending markets already. In one transaction, a borrower drew approximately $1M USDS from SparkLend, converted it into USDC and used it to repay debt elsewhere, moving the WBTC collateral to SparkLend. Collateral supply has grown alongside borrowing. Supplied WETH increased 18.6% and cbBTC 44.7% over the last 30 days, with asset repricing accounting for only around 10% of the $550M increase. SparkLend is lending at greater scale against a larger collateral base than other major lending protocols, and probably has the best rates in the market. SparkLend rates: app.spark.finance/markets

FX Layer picking up steam! I expect this to become the #1 stable-stable swap venue when payments come on-chain due to large scale clearing needs.
Update: PYUSD/USDS pool activity on The Spark Stablecoin FX Layer has surpassed $4B! The pool runs on @Uniswap v4 deploying liquidity on demand at scale. Spark coordinates that depth through the FX Layer's shared liquidity network, keeping capital productive between swaps.

For most savers, yield matters, but so does the volatility you have to take to earn it If you held the 10Y since the beginning of the year, you’d be down 3%: 6% price loss offset by 3% income. Not ideal This is why I find overcollateralized lending in DeFi so high potential for tradfi investors With sound underwriting, you can earn: - yield in real time (thank you blockchains) - take basically no interest rate duration - have instant liquidity (up to 10%) - earn 100bps+ over SOFR There’s a reason AAA CLOs have become so popular in TradFi which give investors a similar profile: floating rate, low duration, low volatility, and a spread over cash I think onchain yields will be very loved by tradfi once we get them comfortable with onboarding, smart contract risk, etc.
With 10-year yields reaching 5%, I've been hearing some funny comparisons with on-chain yield products. "Why should I go into product XYZ if I can get 5% risk-free?" Well yes you will earn 5% risk-free in USD, but let me know how valuable that USD is in 10 years.

SparkLend TVL is approaching ATHs, up 35% in the last month alone. This is when prices are still down. In ETH terms, the market has nearly tripled in size since April. Expecting some explosive growth when the market returns.
