Find the right network for your payment.
Explore supported chains, payment schemes, and assets. Live capabilities come from the facilitator’s supported endpoint.
Coverage by chain family
Counts, assets and schemes below are derived from the live /supported response. A family can have different capabilities on each network.

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.
Network identifiers: CAIP-2
Use the network identifier returned by /supported. Hedera uses x402 v2 with hedera:mainnet or hedera:testnet, when enabled. Other networks may publish both legacy names and CAIP-2 identifiers. The list below shows the identifiers currently advertised by this facilitator.
Understand the network data
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. A network with only exact cannot do the others — that is not an omission, it is the answer.
Gas funding and facilitator wallets
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.
