Supported networks

The facilitator settles x402 payments on Sui Mainnet and Sui Testnet, identified with CAIP-2 network IDs.

Network	CAIP-2 ID	Full node (gRPC)
Sui Mainnet	`sui:mainnet`	`https://fullnode.mainnet.sui.io:443`
Sui Testnet	`sui:testnet`	`https://fullnode.testnet.sui.io:443`

Tokens

USDC is the default stablecoin on both networks. On mainnet, Sui covers gas for transfers of every stablecoin below natively, and the facilitator sponsors what the native path doesn’t — sub-cent payments and any non-stablecoin coin. Either way, a payment of any size settles gasless. All listed tokens use 6 decimals.

Mainnet

Token	Symbol	Native gasless min
USDC (default)	`USDC`	0.01
Sui USD	`USDSUI`	0.01
Ethena sUSDe	`SUI_USDE`	0.01
Ondo US Dollar Yield	`USDY`	0.01
First Digital USD	`FDUSD`	0.01
Agora Dollar	`AUSD`	0.01
USDB	`USDB`	0.01

The native gasless minimum is the smallest transfer Sui covers gas for natively (0.01 of the token, or 10000 atomic units at 6 decimals). Payments below it still settle gasless — the facilitator sponsors them.

Testnet

Token	Symbol	Native gasless min
USDC (default)	`USDC`	none

On testnet the facilitator sponsors gas for USDC payments of any size, so there’s no native minimum to clear.

Pricing in USD

When you price a route as a USD string (for example "$0.01"), ExactSuiScheme converts it to the default stablecoin (USDC) at 6 decimals. To charge in another token, pass an explicit AssetAmount with the token’s coin type — see Quickstart for sellers.
