Circle Mints Roughly 13.5 Billion USDC on Solana in September
Plus: US Spot Bitcoin ETFs Reverse Outflows, Absa Launches Digital Asset Custody on Ripple
Good Morning Lions,
By Crypto Briefing's count, Circle pushed more USDC onto Solana last month than in any month before. I think that says more about where onchain dollars are heading than a single day of ETF flows does. BUT, gross mints get burned too. If net Solana supply barely moves, most of that was churn.. not new demand, and Absa wiring Ripple custody into South African banking matters more.
Circle Mints Record USDC on Solana
TL;DR: Circle minted roughly 13.5 billion USDC on Solana in September, according to an on-chain compilation by Crypto Briefing. The outlet calls it the largest monthly stablecoin mint on the network. The figure counts gross issuance and does not represent net new USDC supply.
US Spot Bitcoin ETFs Reverse Outflows
TL;DR: US spot Bitcoin ETFs took in $102.7 million on Thursday, the first trading day of October, per SoSoValue data reported by Cointelegraph. The inflow reversed Wednesday's net outflow. Spot Ether funds logged a third straight day of net withdrawals.
Absa Launches Digital Asset Custody on Ripple
TL;DR: Absa launched an institutional digital-asset custody platform in South Africa on September 21, 2026, Crypto Briefing reported. The platform is built on Ripple technology. It supports Bitcoin, Ether, XRP Ledger assets and USDC for South African institutions.
Ethereum Foundation Ships zkAPI to Mainnet
TL;DR: The Ethereum Foundation said zkAPI is live on Ethereum mainnet, built together with the Open Anonymity Project. The tool lets users pay for AI and other APIs without revealing their billing identities. It does not hide prompts or network metadata.
Bitwise and Franklin Templeton Clients Buy XRP
TL;DR: Clients of the Bitwise and Franklin Templeton spot XRP ETFs bought another $7.24 million of XRP, Crypto Briefing reported on October 2. Total inflows across XRP ETFs have reached around $1.79 billion.
Saifedean Ammous Questions Bitcoin Treasury Firms
TL;DR: Economist Saifedean Ammous said on Cointelegraph's Proof of Thesis that Bitcoin treasury companies built mainly around buying BTC may struggle to compete with Michael Saylor's Strategy. The comparison centers on Strategy and its $5.02 billion cash reserve.
Four Megacaps Carry the S&P 500
TL;DR: The S&P 500 rose about 2% in Q3 2026 while 311 of its stocks fell, per Crypto Briefing's analysis. Microsoft, Nvidia, Apple and Meta added about 300 points to the index. The rest of the index subtracted roughly 150 points.
Ether ETFs are three days into withdrawals while Bitcoin funds flipped back to inflows. If ETH keeps climbing anyway, frens, the buying is coming from onchain wallets instead of the ETF wrappers. 🦁 — Khal
