Network support

x402 watch supports the following networks:

• Base
• Polygon
• Solana

Support for more is planned, and is being prioritized based on integration grants, volume, and public interest, in that order.

Network Support Pill

The network pill shows which networks the facilitator supports, from the ones x402watch supports. The number in the pill is the number of relayer addresses on that network. Relayers are the wallets that use the ERC3009 standard to transfer a token from your account (or your agent's account) to the payTo address specified by the Seller. In other words, the relayers forward your money to the API seller with just a signature.

Low Gas Alert

All relayer addresses of all the faciliators are regularly checked for low gas.

Low gas on relayers means that the relayers might fail to forward the money, meaning your API will not work, and any sellers using that faciliator on that network might experience a denial of service.

The low gas alert is shown in the network pill, and is a warning icon.

To remove the alert, someone - likely the facilitator's own team - needs to top up the relayer addresses.

Low gas alerts are sent via email to the facilitator's team, if they signed up for the service.
