# Supported Networks

> See networks that are supported by the PayAI Facilitator for the x402 protocol

Use the [Solana network identifiers reference](/x402/solana-network-identifiers) to distinguish the x402 network ID from the RPC genesis hash, or start with the [Solana Mainnet Express guide](/x402/solana-mainnet-express).

## Solana batch settlement

[Batch settlement](/x402/servers/batch-settlement) is available as a public preview for USDC. The public `/supported` endpoint advertises the shared-lane fee payer and admission limits. Its `/verify` and `/settle` requests work without an API key on the shared lane; credentials remain available for paid usage and assigned enterprise lanes.
