Funding rates fell from ~7% to 4.42% below the average stablecoin borrow cost; BTC and ETH kept leaving exchanges; stablecoin supply grew $1.32B; and funding fell from ~7% to 4.42% — all reading as accumulation.

Solana and Hyperliquid L1 absorbed 93% of this week’s stablecoin growth

For opposite reasons: one is a minting rebound, the other is a brand-new lending market that just launched.

Six of the week’s seven biggest token gainers are tied to stocks moving onchain

This Week’s Signal: Stocks Are Becoming DeFi’s Collateral

The single biggest thread this week wasn’t a chain or a token — it was stocks moving onchain, and it touched almost every section of this letter.

It started with regulation. On Sept 17, the SEC granted a temporary exemption letting onchain liquidity pools trade tokenized equities, clearing a legal hurdle that had kept most DeFi apps from listing them directly. Within days, five separate protocols built products on top of it.

Ondo launched Intelligent Portfolios on Sept 24 — three tokens, each wrapping a full BlackRock-designed portfolio strategy into one transferable onchain instrument. Ondo issues and manages the tokens; BlackRock supplied the strategy design only. ONDO rose 33.4% on the week.

Ethena began backing USDe with Binance’s tokenized stocks on Sept. 25, hedged with equity futures the same way it’s long-hedged crypto. Ethena says this expands its addressable collateral from $2.5T of crypto to $150T+ of real-world assets — its own framing, not an independent estimate. ENA rose 31.4%.

Raydium said Solana crossed 1 million tokenized stockholders on Sept. 24, a self-reported figure. RAY’s most-traded pairs this week included SPX and STONK, both memecoins that piggyback on the “stocks onchain” narrative rather than real equities. RAY rose 34.8%, extending a rally that started with a 97% jump in the week to Sept 12.

Aerodrome’s merger with Velodrome, going live Oct 21, is deploying on Robinhood Chain specifically because that’s where the tokenized-stock trading volume is landing. AERO rose 28.3%, mostly in one day.

Pyth, meanwhile, became an external distributor of Nasdaq’s real-time quote data on Sept 22 — the data layer underneath all of this. PYTH rose 44%.


Macro in 3 Lines

Rates and the dollar. The 2-year Treasury yield, the one most tied to Fed expectations, rose about 10bp to 4.86%. The dollar index gained 0.8% to 101.0, its first back-to-back weekly gain since June.

Both moved on the same Wednesday: business surveys came in far hotter than expected, Fed Governor Barr said more hikes are likely, and a weak 5-year auction pushed yields higher.


Week-Ahead Catalysts

Macro:

  • Wed Oct 1: August PCE and Q2 GDP, 8:30 AM ET. PCE is the Fed’s preferred inflation gauge — the first reading since markets moved to pricing in about a two-in-three chance of an October hike.

  • Fri Oct 2: September jobs report, 8:30 AM ET. Forecasts call for +100K jobs, down from 162K, with unemployment rising to 4.2%.

Three crypto events to watch:

  • Jumper (JUMP), Sept 29 to Oct 2: first token sale. The cross-chain trading app has processed $40B+ in lifetime volume with 100,000+ monthly users. Sale runs on Legion; no company equity, so the token is the only way in. US, UK, and UAE are excluded.

  • Hyperliquid (HYPE), Sat Oct 3: first buyback funded by USDC yield. ~90% of interest earned on USDC held on Hyperliquid funds a market buy of HYPE. Analysts estimate $135–160M/year, but the amount moves with USDC balances and rates.

  • Ethena (ENA), Mon Oct 5: all remaining investor tokens unlock at once. Ends the vesting schedule 17 months early. Ethena hasn’t disclosed the size; trackers estimate ~14% of circulating supply. ENA roughly doubled in September heading in. Buyback stays off until USDe supply hits $7.5B.


Capital On-Ramp

Spot Bitcoin ETFs took in $2.39B from Sept 21–25, their strongest week of 2026, beating the previous high of $1.92B in August. Every day was positive, but the pace fell sharply — from $999M Monday to $134.5M Friday. Ether ETFs added $689.8M, reversing last week’s −$140.9M outflow (their first since July). Solana ETFs added $188.1M.

Exchange balances fell at the same time. BTC held on exchanges dropped 1.4% to 2.689M BTC, reversing last week’s rise — coins moving off exchanges usually means holders are keeping them rather than preparing to sell. ETH on exchanges fell 1.1% to 14.64M, most of it on Sept 22–23.

Stablecoin supply grew $1.32B (+0.43%) to $306.4B — new stablecoins arriving onchain, though modest against the ETF number.

Verdict: Institutional demand was the strongest of the year and held Bitcoin up through a bond selloff, but it was front-loaded and didn’t carry price higher after Monday.


Onchain Risk Regime

USDC added $789M, and USDT added $388M. Tokenized Treasury funds, held mainly for yield rather than trading, split: Ondo’s USDY grew $333M and Circle’s USYC grew $229M, while BlackRock’s BUIDL fell another $201M (−24.4% over 30 days).

The cost of borrowing stablecoins was 4.82%, and lenders earned 3.72%. The funding rate — what leveraged perpetual-futures traders pay to hold positions — fell to 4.42% from about 7% around Sept 20, now sitting just under the borrow rate. The gap that made leverage expensive last week has closed.

ETH/BTC closed down about 2% at 0.0318, still above its 20-week average of 0.0304. ETH lost ground to BTC, even though Ether ETFs saw $690M in inflows compared with Bitcoin’s $2.39B.

Verdict: Trading cash is arriving, and leverage got cheaper to hold, while ETH lagged BTC and a top tokenized-Treasury fund shrank for a second straight week — MIXED, tilted risk-on.


Chain Comparison: Solana and Hyperliquid L1 took 93% of the week’s growth

Stablecoin supply rose $1.32B (+0.43%) to $306.4B in the last 7 days. Solana added $835M and Hyperliquid L1 added $396M, together 93% of that. The two gains came from different coins, and Hyperliquid’s is all USDC, not USDT plus USDC as first thought.

Solana: +$835M (+5.35%), two-thirds of it USDT

Per coin:

  • USDT rose 26%, about +$550M, to $2.67B.

  • USDC added about $186M, to $7.24B.

This is a rebound. USDT on Solana fell about $720M over the prior three weeks, so this week recovered most of it.

The trigger was a burst of minting when issuers created new coins for a customer who deposited dollars. SolanaFloor reports that Tether minted $530M of USDT and Circle $751M of USDC on Sept 25, pushing supply to a record $17.3B by Solana’s own count. That is single-sourced, and DefiLlama’s total is lower. USDC’s net gain of $186M against $751M minted shows gross minting overstates growth, because redeemed coins are burned.

Where are the stables flowing?

  • Jupiter Lend hit a record $2.41B in deposits on Sept 22, up 27% from August over about six weeks. With $823M borrowed, utilization is 34%, meaning most supplied money is idle.

  • Kamino Lend holds about $2.6B supplied with $1.07B borrowed.

  • Kamino widened what stablecoins can be borrowed against. On Sept 22 it launched Fixed Rates, which lock a borrow rate for a term. The first vault, built with Hastra and Figure, charges 5.3% on rolling 30-day terms. It also opened a sterling market (tGBP) and, on Sept 24, a market for USD.AI’s sUSDai token. These add credit demand, but at these sizes they don’t account for a $550M USDT increase.

Hyperliquid L1: +$396M (+5.46%), all USDC

USDC on Hyperliquid is now $7.55B, more than Solana’s $7.24B. USDT there is only $85.5M and grew $1M.

On Sept 18, Hyperliquid launched a lending market built into its exchange. Users pledge HYPE or BTC as collateral to borrow USDC or USDT, and $269M was borrowed on day one. HYPE hit a record $94.45 the next day. The timing fits the USDC gain.

Only $634M, about 8%, sits in the separate HyperEVM lending apps (HyperLend $429M, Morpho $193M). Most of the rest is collateral for trading.
