The x402 Foundation has 40 member organizations as of its July 14, 2026 operational launch: 17 premier members, 18 general members, and 5 associate members. It began with 22 founding members on April 2, 2026, when Coinbase contributed the x402 protocol to the Linux Foundation. The premier roster includes Visa, Mastercard, American Express, Stripe, Google, AWS, Circle, Cloudflare, Coinbase, Ripple, and Shopify — the card networks, the cloud providers, and the crypto rails at one governance table. This is the complete roster, by tier, with what each heavy hitter actually brings — and the honest caveat no member announcement mentions.
| Last 30 days | Figure |
|---|---|
| Transactions | 75.41M |
| Volume | $24.24M |
| Buyers | 94.06K |
| Sellers | 22K |
75M transactions moving $24M in 30 days: the signature of sub-cent, high-frequency machine payments — enormous transaction counts, tiny average values. That is the machine-native economy in one dashboard.
| Member | What they bring to the table |
|---|---|
| Coinbase | Built x402; contributed the protocol; co-founder with elevated governance |
| Cloudflare | Edge network; co-founder with elevated governance |
| Stripe | Payments giant; co-founder with elevated governance; also building its own MPP agent-payment rail |
| Visa | Card network; also building its own TAP agent protocol — at the x402 table anyway |
| Mastercard | Card network |
| American Express | Card network; EVP Global Innovation quoted in the launch release supporting "open, interoperable standards" |
| Adyen | Merchant payments; CTO quoted in the launch release |
| Fiserv | Merchant solutions / banking infrastructure |
| Circle | USDC issuer — the asset doing ~99.99% of current agentic settlement (see caveat below) |
| Cloud + AI; runs its own A2A agent protocol and AP2 payments protocol | |
| AWS | Cloud; GM of AWS Payments and Fraud Prevention quoted in the launch release |
| Shopify | Commerce platform — agent checkout at merchant scale |
| MoonPay | Fiat on-ramp |
| Ripple | XRP + RLUSD settlement on the XRP Ledger — the first major non-USDC settlement path at the governance layer |
| Solana Foundation | Solana ecosystem |
| Stellar Development Foundation | Stellar network — second non-EVM settlement path at the governance layer |
| Monad Foundation | Monad L1 ecosystem |
Why this mix matters: x402 is trying to sit between worlds — wallets, stablecoins, card networks, cloud providers, agent platforms, API sellers, compliance. The Foundation's own framing: the spec spans "traditional cards to stablecoins," with "no vendor lock-in." Competitors building against one neutral spec is what turns a protocol into infrastructure.

Notable: Polygon Labs and KakaoPay were among the 22 founding members in April; Fireblocks and LayerZero bring custody and cross-chain messaging; Kite AI is agent-native. Microsoft and Thirdweb were founding members in April but do not appear in the July premier/general/associate lists in the Linux Foundation release — membership tiers can shift between announcements.

| Coverage | What it lacks |
|---|---|
| Linux Foundation press release (July 14, 2026) | The primary source — full roster and exec quotes. But it's a press release: no analysis, no volume honesty, no member-by-member breakdown. |
| agenttoll.dev — "X402 Got Its Standards Body. Now Comes the Hard Part." | Best governance read of the bunch (why neutral governance matters for competitor buy-in). No full roster, no tiers, no volume caveat. |
| Crypto press rewrites (April + July waves) | Headline + premier names; nobody published the complete 40 with tiers, and nobody noted the governance-vs-settlement gap. |
Everyone covered the announcement. Nobody published the roster as infrastructure intelligence: all 40 members by tier, what each heavy hitter structurally adds (Ripple's XRP+RLUSD path, the card networks' "traditional cards to stablecoins" span, the co-founder governance roles), and the gap between who governs and what settles. A payment standard only works if competitors build against it — the member list is the adoption signal, and it deserves a canonical page with receipts instead of a press-release rewrite.
And the dashboard tells the real story underneath: 75.4M transactions, $24.2M volume, 94K buyers, 22K sellers in 30 days. Enormous counts, tiny values — the machine-payment economy is already running. It's just not evenly distributed yet.

A: 40 member organizations as of the July 14, 2026 operational launch — 17 premier, 18 general, 5 associate. It started with 22 founding members at the April 2, 2026 announcement.
Q: Who are the premier members?
A: Adyen, AWS, American Express, Circle, Cloudflare, Coinbase, Fiserv, Google, Mastercard, Monad Foundation, MoonPay, Ripple, Shopify, Solana Foundation, Stellar Development Foundation, Stripe, and Visa.
Q: Who runs the x402 Foundation?
A: The Linux Foundation, as a neutral governance home. Coinbase contributed the protocol on April 2, 2026. Coinbase, Cloudflare, and Stripe are co-founders with elevated governance roles.
Q: Is x402 still just for crypto?
A: No. The spec spans "traditional cards to stablecoins" per the Foundation announcement, and the premier tier includes Visa, Mastercard, and American Express alongside crypto-native members.
Q: Does membership mean payment volume is diversified?
A: Not yet. Governance diversified; settlement hasn't — one ecosystem tracker's August 2026 figures put USDC at ~99.99% of trailing-90-day agentic transfer volume. The Ripple and Stellar paths are real at the governance layer but under 1% of actual volume.
