Ask where this facilitator can settle, and see what it pays to do it
21 payment mainnets and 18 testnets across 7 chain families, every chain under two names, every row read live from /supported — with the gas balance we spend on your behalf in the last column.
Where this settles, by chain family
A summary of the live table below, as it stood on 2026-09-03. If the two ever disagree, the live table is right: it is read from /supported and this one is not.
| Chain family | Mainnets | Testnets | Stablecoins settled | Schemes |
|---|---|---|---|---|
ET EVM |
14 | 12 | USDC, USDT, EURC, AUSD, PYUSD, USDG | exact, upto, escrow, commerce, fhe-transfer |
SO Solana / SVM |
2 | 2 | — (feePayer) | exact |
XR XRPL |
1 | 1 | USDC, RLUSD, XRP | exact |
ST Stellar |
1 | 1 | — (feePayer) | exact |

Two things this table does not claim.
The tokens column is what the facilitator will settle on that chain, not what your seller accepts — the seller's 402 decides that, and x402_accepts narrows it. The balance column is the facilitator's own native-token balance, the gas it spends on your behalf; it is not your money and it is not the payment. A dash means the balance was not reported for that network, never that it is zero.
The same chains, in CAIP-2
Every network here also answers to a CAIP-2 identifier, and both spellings work everywhere a network is named. They are not shown next to each other, and that is a deliberate refusal rather than an omission: /supported publishes the two spellings as separate entries with no field linking them, and for most chains it publishes no token list under the CAIP-2 form either — measured on 2026-09-02, 49 of the CAIP-2 entries carry no tokens. Pairing them from the page would mean guessing, and a wrong chain id printed next to the right network is worse than no chain id at all. The list below is verbatim from the endpoint.
Reading a row
The schemes column matters more than it looks. exact is the ordinary x402 payment. upto authorises a ceiling and charges what was used, and is advertised only where the Permit2 proxy is actually deployed. escrow and commerce hold funds until a condition is met. fhe-transfer is confidential and experimental. A network with only exact cannot do the others — that is not an omission, it is the answer.
The wallets that pay the gas
These are the addresses this facilitator broadcasts from, one pair per chain family. They are public, they are linked to their explorer, and the gas balance of each is the last column of the live table above. An address on one page and its balance on another is how a reader ends up trusting neither.
