• Solana stablecoin card spending hit $141.1 million in October, a fourth straight monthly record.
• October volume ran about seven times the $20 million recorded in October last year.
• KAST processed $100.4 million, close to three quarters of Solana's October card volume.
A Fourth Straight Monthly Record
Card programs on the Solana (SOL) network settled a record $141.1 million in stablecoin spending during October, on-chain payments data shows, an all-time high for the metric and the fourth consecutive month to set a new record. The figure counts stablecoins users paid at merchants through cards linked to on-chain balances, a consumer flow separate from trading volumes tied to the Solana price. October's total runs roughly seven times the near $20 million of October last year, and about 24% above September's high. September's high, itself a record at the time, lasted exactly one month. Growth through 2026 has been close to uninterrupted. Card spend stood near $44.5 million in January, and volumes have since more than tripled across ten months, with every month this year except June printing a fresh high. August was the first month above $100 million. Each program on the network issues its own cards and settles the underlying transactions in stablecoins, which is what makes the spending traceable at program level. A stablecoin card draws on a token balance and converts it into spendable currency at the point of sale, so the metric tracks everyday payments rather than speculation: purchases settled on-chain and cleared through card rails. That distinction shapes how the record reads. Trading volume swings with market conditions, while card spending measures how much real-world purchasing users route through the network, month after month. On that measure October was the chain's strongest month yet, with the streak now spanning most of the year. Where the volume sits across the Solana network matters as much as the total.
KAST and Rain Hold 93% of the Spending
The concentration behind October's number is extreme. KAST, the stablecoin neobank whose cards let customers hold and spend token balances, processed $100.4 million in October, close to three quarters of everything spent on the network. Rain provides the card infrastructure other companies use to launch their own stablecoin cards, and cards issued on its rails added another $31.66 million. Together the two account for 93% of October's total card spending, which puts them among the top Solana projects by consumer volume. The long tail is thin. Avici led the rest at $2.28 million, with Tria on $1.84 million, Bridge-issued programs on a combined $1.65 million and Solayer on $1.29 million. Wallet-native cards, where users pay directly from self-custody wallets, are still marginal: Phantom Cash, MetaMask and Solflare managed only about $2 million between them. Ranked across chains, Solana's card total sits third. The all-chain market came to $938.2 million in October, close to a $1 billion monthly run rate. Base led the field at $259.1 million, roughly 28% of everything spent, while Optimism held second at $144.6 million (15.4%). Solana's $141.1 million (15%) left it $3.5 million short of second place, and those three chains cleared about 58% of all card spend last month. Arbitrum handled $86 million, Stellar $74 million, Polygon $63.7 million and Plasma $49.5 million, with the remaining 11 chains adding a combined $120.1 million. Second place is close enough that a single standout month from KAST could reorder the table, and Solana has outgrown most of the field this year. Cheaper execution helps these consumer programs: the merged SIMD-0567 token account proposal, which cut compute costs by 81%, is part of the network's effort to keep small transactions economical.
The narrowness of the base is the main risk inside the record. KAST alone carried close to three quarters of Solana's October card volume, and Avici, the biggest card program beyond KAST and Rain, managed roughly 2% of what KAST processed in October, so nothing on the network today could absorb that volume if KAST's growth flattened or its users moved elsewhere. The same concentration cuts the other way: with Solana $3.5 million behind Optimism, one more month like October from KAST would carry the network into second place across all chains. The spending record also lands against a softer institutional backdrop, with Bitwise and Grayscale recently leading record $71.5M weekly Solana ETF outflows. How far this use actually runs stays bounded by what the data shows: outside KAST and Rain, wallet-native card spending is still measured in single-digit millions.
