Payments Roundup: September 2026

**Source:** https://x.com/solanapayments/status/2108637161985802517 Payment Channels went live on September 3, putting 1,000,000 payments per second on Solana. @rishinsharma, Head of AI Growth at Solana Foundation, described the mechanic plainly: "Think of it like a bar tab or a prepaid meter: you put money down up front, run up usage without paying for each transaction, and settle payment once when you leave." Two weeks later a bank put stablecoins in its core. @column, the FDIC-insured bank behind Brex and Slash, made USDC and USDT on Solana convertible to and from dollars 24/7. The month closed with OUSD going live from @openstandard. Stablecoin supply on Solana hit an all-time high of $17.3B on September 25. Daily stablecoin active addresses reached 888K in September, up 269% from 333K a year earlier. Solana carried 420M USDC transactions in a month and 76% of all @x402 transactions, 23.2M in four weeks against 3.39M on the next-largest network. https://preview.redd.it/5d2288v3zkuh1.png… Here's what happened across September for payments on Solana: # Agentic Payments * Payment Channels shipped on Solana, taking agentic payments to 1,000,000 per second over @x402 or MPP, with u/@alibaba\_cloud API endpoints payable through it on day one * Solana took 76% of all @/x402 transactions, 23.2M in four weeks, and led both transactions and volume week after week * Solana processed 1.81M x402 agent payments in a single 24 hours (@tokens, Sept 2) * @nansen\_ai hit a weekly x402 ATH on Solana, settling more there than on all other networks combined, with agents buying its smart money data a cent at a time through @PayAINetwork https://x.com/solana/status/2095577162598236283 https://preview.redd.it/jfy9jvp9zkuh1.png… # Banking & Stablecoin Issuance * @column, the FDIC-insured bank behind Brex and Slash, built stablecoins into its banking core, with USDC and USDT on Solana convertible to and from dollars 24/7 * OUSD went live on Solana from @openstandard, issued by @Stablecoin with reserves at @BlackRock, @Lead\_Bank and BNY, mintable and burnable 1:1 at no cost through @BVNKFinance, @stripe and Visa's Stablecoin Platform * CADD from @TetraDigitalGrp launched on Solana, bringing the Canadian dollar onchain for payments, transfers, treasury and settlement * ZARsc, a Rand-pegged stablecoin, went live on Solana, issued by @supercoinxyz under an FSCA licence with custody by @fireblocks and screening by @Chainalysis # Business Payments & Treasury * @altitude acquired Acctual, a stablecoin-native invoicing platform, and opened four new markets: UK, Mexico, Brazil and Colombia * $2.44B in stablecoin volume was authorized through @multisig on Solana in August, a monthly ATH and more than double July (@surfquery) * @cloak\_ag shipped private payroll on Solana * PST by @humafinance became the largest yield-bearing asset on Solana # Cards & Spending * @KASTxyz passed $2B in all-time deposits after five consecutive weeks of growth ( @Paymentscan) * @NOMADZxyz opened flights and stays to stablecoin payments on Solana, 300+ airlines and 1M+ stays, with a 3% saving for paying in stablecoins # Remittances & Cross-Border * Everything on remittances sits in Solana Foundation's report, An Evolution of Money Movement: the composable stack, five business models beyond money movement, four entry paths, and corridor deep dives for US to Mexico, Brazil, Nigeria, the Philippines and India # Tokenized Cash & Capital * Africa's biggest IPO opened for subscription with stablecoins on Solana: the Dangote Petroleum Refinery offer, live on @Nectar\_finance and powered by @GetEquity, with a ₦10,000 minimum and the offer closing October 13 * Project Harmonia opened for applications. @Allfunds connects 3,300+ asset managers and financial institutions with €1.9T under administration, and tokenized funds on Solana can now apply to reach them https://x.com/Nectar\_finance/status/2099531191246369093 https://preview.redd.it/6ggjx2jnzkuh1.png… # Data * Stablecoin supply on Solana hit an all-time high of $17.3B (Sept 25) * Daily stablecoin active addresses reached 888K in September, up 269% from 333K a year earlier * 420M USDC transactions settled on Solana in a month (Sept 18) * Solana is #1 for monthly USDC senders at 6.2M in 30 days, 42% of everyone sending USDC and 2.5x the next network (Sept 9) https://preview.redd.it/zwyowyoozkuh1.png… # Solana Foundation * Jamal Raees ( u/@proofofjamal ) was named General Manager of Payments at Solana Foundation on September 24, working with payment companies and enterprises to expand Solana as global payments infrastructure.
