↓ -7%Circle has launched cirBTC, positioning it as "neutral" wrapped Bitcoin infrastructure without ties to exchanges or lending protocols, in contrast to rivals WBTC and Coinbase's cbBTC. However, adoption remains minimal. Circle's latest reserve data from 28 July showed just 40 cirBTC in circulation, backed by 42 BTC. By comparison, WBTC had 116,499 tokens outstanding against 116,514 BTC on 29 July, whilst Coinbase reported 95,492 cbBTC backed by 95,503 BTC as of 31 July. Circle emphasises transparency through Chainlink Proof of Reserve monitoring and public disclosure of Bitcoin addresses. The token launched on Ethereum on 8 June, with multichain support planned. DeFi integration will prove critical. Aave Labs has proposed adding cirBTC as collateral, though a June risk assessment cited limited liquidity concerns. Meanwhile, cbBTC had already seen 18,917 tokens supplied to Aave V3 Core by late June.
Base emerges as a dominant force in stablecoin card payments. Coinbase's Layer 2 network now handles roughly 19% of all tracked crypto card spending as Visa's stablecoin settlement pilot hits a $7B annualized run rate 2 hours ago Via techcrunch.com Sponsored: CryptoSlots - Cryptoslots Play now! The idea of paying for your morning coffee with stablecoins used to sound like a crypto fever dream. Now it's a $759 million-per-month business, and Coinbase's Base network is quietly becoming the infrastructure layer that makes it work. As of July 2026, Base accounts for approximately 19% of all tracked crypto card spending volume, making it one of the largest blockchain networks powering stablecoin-linked payment cards. That puts it in a dead heat with Solana, also at 19%, while Optimism leads the pack at 29%. The numbers behind the growth. Monthly on-chain transaction volumes for crypto card programs reached around $759 million in July 2026, with nearly 9 million individual purchases recorded. Annualized, that puts the stablecoin card market in the neighborhood of $18 billion. Visa has been the single most important accelerator of this trend. On April 29, 2026, the payments giant expanded its stablecoin settlement pilot to include Base, bringing the total number of supported blockchains to nine. After that expansion, the pilot reached a $7 billion annualized run rate. Visa's stablecoin-linked card programs now exceed 130 across more than 50 countries. The dominant assets flowing through these programs are USDC and USDT, the two largest dollar-backed stablecoins by market cap. Why Base keeps winning card issuers. Base's appeal to card program issuers comes down to three things: low transaction fees, fast finality, and native USDC support from Circle. Transaction fees on Base typically run a fraction of a cent, which matters enormously when you're processing millions of small-ticket purchases per month. Base's architecture as an Ethereum Layer 2, using optimistic rollup technology, delivers transaction confirmations quickly enough to meet the expectations of traditional payment rails. Circle, the issuer of USDC, has deep integration with Base, which isn't surprising given that Coinbase is both a Circle investor and the operator of Base. That tight relationship means USDC minting, redemption, and settlement on Base are essentially first-class operations. Card issuers building on Base don't have to worry about liquidity gaps or bridging headaches when their users spend USDC at checkout. The competitive landscape. Base isn't operating in a vacuum. Optimism currently handles a larger share of crypto card spend at 29%, and Solana matches Base's 19% share while offering its own advantages in speed and developer ecosystem. Visa's decision to support nine blockchains rather than picking a single winner suggests the payments giant is hedging its bets. That multi-chain approach gives card issuers flexibility but also means no single network has a monopoly on Visa's stablecoin volume. Mastercard has been making its own moves in the stablecoin space, adding another dimension to the competitive picture. Disclosure: This article was edited by Editorial Team.

The South Florida Wire: GPU clouds, stablecoin rails, and a $65M angel merger (week of august 12, 2026). Issue #1 of the weekly South Florida tech and VC roundup. This one's a catch-up: the rounds, moves, and office openings that define where the region stands in mid-August 2026. Co-Founder & GP at Six Point Ventures · 3x founder (BrandYourself, Launch.it, SPOT) · 65+ investments · Based in Boca Raton, FL 65+Investments 3xFounder $200M+Funds Tracked Quick Answer The South Florida Wire is Value Add VC's weekly roundup of verified South Florida tech news. The debut issue covers the region's defining 2026 stories: Hydra Host's $100M Series A at a near-$800M valuation (Kindred Ventures, Nvidia, Founders Fund), Cyclops' $20M Series A for stablecoin settlement (Nava Ventures, Coinbase Ventures, Circle), eMed's $200M raise at a $2B+ valuation with Linda Yaccarino as CEO, the $65M Miami Angels-New World Angels merger creating one statewide angel network, Thiel Capital opening a Wynwood office, and ServiceNow's 211K sq ft West Palm Beach lease. This is the first issue of The South Florida Wire - a weekly, sourced-only roundup of the tech and VC news that actually matters from Miami to West Palm Beach. Because it's issue #1, this one is a catch-up: the rounds and moves that define where South Florida stands in mid-August 2026. The theme is easy to spot - the region has graduated from relocation headlines to real capital formation. The biggest rounds of the year aren't lifestyle plays; they're AI infrastructure, payments rails, and healthtech, led by Kindred Ventures, Nvidia, Aon, and Coinbase Ventures. Every item below is verified against primary reporting. If Value Add VC can't source it, it doesn't run. This week's rounds. A debut-issue snapshot: the rounds that shaped South Florida's 2026 so far, newest first. * Cyclops - $20M Series A led by Nava Ventures, with Castle Island Ventures, Coinbase Ventures, Circle, and Global PayTech Ventures. The Miami startup, founded by The Giving Block's Alex Wilson and Pat Duffy, settles payments in stablecoins for clients including Shift4 and Mastercard - $28M raised total after a March seed (Fortune). * Interchecks - $50M Series C from Bettor Capital, Commerce Ventures, Decades Holdings, and Thayer Street Partners for its Miami-based instant-payouts platform (Refresh Miami). * Hydra Host - $100M Series A led by Kindred Ventures, with Nvidia, ARK Invest, Comcast Ventures, and Founders Fund, at a valuation approaching $800M. The Miami company brokers bare-metal GPU capacity from overlooked data centers for AI labs (Refresh Miami). * Lexful - $7M seed co-led by Top Down Ventures and York IE for the Hallandale Beach startup rebuilding IT documentation for the AI era (Refresh Miami). * eMed - $200M Series A at a $2B+ valuation led by Aon, with Tom Brady, Joe Lonsdale, and Antonio Gracias participating. The Miami GLP-1 employer platform is run by CEO Linda Yaccarino (PR Newswire). Moves & openings. * Miami Angels + New World Angels - merged into a single $65M statewide angel network, combining Miami Angels' 60+ portfolio companies since 2013 with New World Angels' 22-year Boca Raton track record. One front door for Florida angel capital (Refresh Miami). * Thiel Capital - opened a Miami office in Wynwood, complementing its Los Angeles operations, with the lease signed in December 2025. Founders Fund has been in Miami since February 2021; now the family office is here too (Business Wire). * ServiceNow - the ~$200B enterprise software company leased 211,845 sq ft at 10 CityPlace in West Palm Beach, the largest corporate tech commitment Palm Beach County has landed, with 1,000+ hires planned by 2028 (its deep dive). * OpenEvidence - the AI clinical search company that moved its HQ to Miami in 2025 hit a $12B valuation in January after a $250M Series D from Thrive Capital and DST Global - doubling its value in three months (MobiHealthNews). Worth knowing. The check sizes changed, and that's the whole story. Three years ago the South Florida narrative was VCs buying houses. In 2026 it's Kindred and Nvidia writing into a $100M Miami Series A, Aon leading $200M into eMed, and OpenEvidence carrying a $12B valuation from a Miami HQ. When tier-1 leads price nine-figure rounds here without blinking, the "is Miami real" debate is over - the market settled it. The angel merger matters more than any single round. Florida's early-stage problem was never capital - it was fragmentation. Miami Angels and New World Angels spent two decades running parallel processes 40 miles apart. One $65M network with a single application means seed founders stop doing the same pitch three times, and follow-on syndicates form statewide. That's plumbing, and plumbing is what turns a scene into an ecosystem. Every round above lives in its South Florida Funding Tracker - the running, source-verified record of every SoFl tech round Value Add VC can confirm. And if you're raising down here, start with the Miami VC firm directory to see who's actually writing checks. The Wire returns next Friday.

Circle stock surges 6% to $71 as CRCL rebounds. The rally comes after CRCL fell below $60 following its Q2 results, with the stock now approaching the key $72.50 resistance level. Published 3 hours ago · Updated 2 hours ago Key Highlights * Circle stock rose 6% to $71.11 after reaching $73.35. * CRCL has recovered from its recent low of $57.84 following the Q2 earnings sell-off. * $72.50 is now a key resistance level, with a break above it potentially pushing the stock higher. Circle stock (CRCL) rose nearly 6% on Tuesday, trading at $71.11 as of the time of reporting. The shares reached an intraday high of $73.35 before pulling back. The move pushed Circle's market capitalization to about $19.41 billion, while its average daily trading value stood at around $13.9 million. Back above $71 after Q2 results. The latest gain comes days after the stock fell below $60 following the company's second-quarter results released on August 5. Circle reported earnings per share of $0.18, matching analysts' expectations. The company also raised its full-year revenue outlook and pointed to the approval of its U.S. national trust bank charter as an important development. The initial gains in the stock did not hold. The Crypto Times, at the time, reported that Circle shares fell more than 3% in early trading after first gaining about 7% in premarket trading. The stock reached a session low of $59.12 before recovering to around $61.20 at the time of the report. Circle's USDC business keeps growing. The fall came even as Circle's main stablecoin business continued to grow. USDC in circulation reached $73.3 billion at the end of the second quarter, up 19% from a year earlier. Circle's total revenue and reserve income rose 7% to $701 million, while adjusted EBITDA increased 8% to $143 million. Net income from continuing operations came in at $48 million. The company also highlighted its newly approved U.S. federal trust bank charter. CRCL recovers from $57.84 low. Following the earnings-related decline, Circle shares fell to a corrective low of $57.84 before recovering. Circle shares subsequently moved back above their 20-day moving average on Friday, with the full trading range remaining above that level. The shares also stayed above the moving average on Monday. On the weekly chart, CRCL closed at $66.67 after reaching $57.84. That was above the previous week's high of $66.24 and marked its highest weekly closing price in seven weeks. RSI points to weaker selling pressure. At the same time, the stock's Relative Strength Index, known as RSI, on the daily chart also shows a bullish divergence build-up. This means the price was making new or similar lows while the momentum indicator was showing signs of less downward pressure. Now, the stock is approaching a key resistance level at $72.50. The daily chart shows that the price remains below this area after several attempts to move higher, making it an important level to watch. A decisive move above $72.50 could signal further upside if buying momentum continues. If the stock fails to clear the resistance, the price could retest support near $60.
