Key findings
- SpendNode observed $79.19 million of crypto card spending across 11 mapped programs in the seven days through September 20, up 3.23% from the immediately preceding UTC week.
- Eight programs grew and three declined. Plasma One supplied $1.02 million of the measured set's $2.48 million net increase.
- Plasma One posted the fastest growth among programs above $1 million, rising 19.5% to $6.23 million even as its settlement-event count declined.
- Ether.fi and KAST remained first and second at a combined $54.31 million, or 68.6% of observed spend.
- Optimism remained the largest settlement chain at 36.7% of the measured total, followed by Solana at 34.5%.
The weekly close
Observed spending reached $79,189,463 between September 14 at 00:00 UTC and September 21 at 00:00 UTC. The comparison uses the same 11 programs and measurement rules as the previous close, so the 3.23% increase does not reflect a coverage change.
Multiplying this week's observed total across 52 weeks gives about $4.12 billion. That figure shows the scale of the measured set; it is not a forecast or an estimate of the entire crypto-card market.
Plasma One made the largest contribution to growth, adding $1.02 million. KAST added $719,162, ether.fi added $263,961, and xPlace added $258,249. Smaller increases at Avici, Wirex One, MetaMask, and Peanut brought the combined gain across eight programs to $2.54 million.
Three programs declined by a combined $67,815. Jupiter recorded the largest reduction, falling $50,613, while Tria declined $9,904 and Gnosis Pay declined $7,297.
Measured crypto card spending increased 3.2% in the week through September 20, with eight of the 11 mapped programs recording growth.
Plasma One led the increase
Plasma One grew 19.5% to $6.23 million, the fastest increase among programs above $1 million. Its observed active-wallet count rose 2.6% to 11,483, but settlement events declined 4.7% to 32,384. Average observed value per event consequently increased from $153.49 to $192.42. The pattern is consistent with fewer, larger observed settlements, but the chain data cannot distinguish larger purchases from batching or settlement timing.
Avici recorded the next-fastest percentage increase, rising 15.6% to $944,019 across its current Solana and EVM routes.
MetaMask grew 5.1% to $782,496 across its observed Base, Linea, and Solana rails. Three Base entries involving EURC were excluded because that token does not have a supported mapping in the current collector. Wirex One increased 2.1% to $5.73 million, while Peanut rose 2.9% to $22,371.
Jupiter posted the largest percentage decline, falling 2.8% to $1.73 million. Gnosis Pay eased 0.4% to $1.75 million, and Tria was nearly flat at $5.07 million, down 0.2%.
xPlace spending rose during its rewards reset
September 14, the first day of this measurement window, was also the effective date of xPlace's revised reward terms for newly purchased memberships. Credit Mode cashback fell to 0.5-2% by tier and Cash Mode cashback fell to zero. Memberships purchased before September 14 retain their earlier rates for up to 12 months.
Measured xPlace spending nevertheless increased 10.9% to $2.62 million while observed active wallets declined 4.8%, from 1,534 to 1,461. Observed spending per active wallet rose about 16.5%, from $1,540 to $1,793. This does not establish that the reward reduction increased demand: the chain data cannot separate grandfathered members from newer ones, identify membership tiers, or explain the higher value per wallet.
The two largest programs held their share
Ether.fi remained first at $28.79 million, up 0.9%, while KAST remained second at $25.52 million, up 2.9%. Together they represented $54.31 million, or 68.6% of observed spend, compared with 69.5% in the preceding week.
Ether.fi's observed spend-event count increased 2.1% to 371,748. Because volume grew more slowly, the average observed value per event declined from $78.34 to $77.45.
KAST again settled through seven issuer batches: six on Solana and one on Ethereum. Those batches are not individual card purchases and do not expose active-cardholder counts.
Chain shares were comparatively stable
Optimism remained the largest settlement chain at $29.02 million, or 36.7% of observed spend. Solana followed at $27.35 million, or 34.5%. Plasma accounted for $6.23 million and Arc for $5.73 million.
The leading-chain order and KAST routing were similar to the preceding week, when six of seven KAST batches also landed on Solana. Solana's measured share edged up from 34.2% to 34.5%, while Optimism's declined from 37.6% to 36.7%.
The chain table records where mapped value settled onchain. It is not blockchain market share for all crypto cards, and issuer-batch routing can move its columns without an equivalent change in purchases.
Measurement notes
This report covers a closed seven-day UTC period. It combines purchase-level wallet debits, card-settlement events, and issuer settlement batches only where each program's public methodology labels the basis. Event counts are compared within programs and are not treated as interchangeable across different settlement designs.
Later offchain refunds and chargebacks may not return through the same onchain route, so several series are gross rather than net. KAST's seven transactions are issuer settlement batches, not seven card purchases. MetaMask's identified Monad rail and Avici's unidentified retired route remain outside coverage.
Wirex produced 15 events carrying the unsupported currency code TGB during the September month-to-date collection. Those events are excluded from the MTD row rather than assigned an assumed exchange rate; they did not occur in this weekly interval.
The preceding week and this report are frozen snapshots. Their downloadable CSV, JSON, and chart files keep stable URLs. If stronger evidence changes a published result, SpendNode will label and date the correction rather than silently rewriting the weekly close.
