Package com.tnsai.payment.x402

Enum Class Network

java.lang.Object

java.lang.Enum<Network>

com.tnsai.payment.x402.Network

All Implemented Interfaces:

Serializable, Comparable<Network>, Constable

public enum Network
extends Enum<Network>

Settlement networks the x402 adapter can target.

The list is intentionally short. Each entry corresponds to a published scheme in the x402 spec (Base on EVM, Solana on SVM) and to a Coinbase facilitator that already accepts authorisations for that chain. Adding a new network here is a deliberate decision — it implies a tested chain RPC, a working facilitator, and a settlement-asset address (USDC etc.) that the adapter trusts.

Since:

0.10.5 (TNS-449 P2)

Enum Constant Details

BASE_MAINNET

public static final Network BASE_MAINNET

Base mainnet (EVM, chain id 8453). Real USDC, real money.

BASE_SEPOLIA

public static final Network BASE_SEPOLIA

Base Sepolia testnet (EVM, chain id 84532). Faucet USDC, no real value.

SOLANA_MAINNET

public static final Network SOLANA_MAINNET

Solana mainnet. SVM-shaped signing scheme, USDC settlement.

Method Details

values

public static Network[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static Network valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

canonicalId

public String canonicalId()

Stable lowercase identifier used in config files and on the wire. Matches the x402 spec's network slugs verbatim.

chainId

public int chainId()

EVM chain id (EIP-155). 0 for non-EVM networks — callers should switch on family() before reading this.

family

public Network.Family family()

Signing-scheme family.

ofCanonicalId

public static Network ofCanonicalId(String id)

Resolve a canonical id back to its enum value. Lookup is case-insensitive via Locale.ROOT to keep behaviour stable across user locales.

Throws:

IllegalArgumentException - if id doesn't match any known network
