USDC on Base, USDG on Robinhood Chain: and the rails behind them.
MeshGateway settles in USDC on Base and USDG on Robinhood Chain, and the protocol is network-agnostic: any EVM chain with an EIP-3009 stablecoin can be added as a settlement target.
| Network | Stablecoin | Rail |
|---|---|---|
| Base | USDC | EIP-3009 transferWithAuthorization |
| Robinhood Chain (chain 4663) | USDG | x402 exact scheme over Permit2 witness transfers: see Robinhood Chain rail |
The first mainnet MPP payment settled in USDG on Robinhood Chain in 2026.
Base (EIP-3009)
USDC supports EIP-3009 transfer authorizations natively: the buyer signs a
transferWithAuthorization for the exact amount made out to the merchant's
wallet, and the gateway submits it on-chain. The buyer needs no ETH: the
payment is only a signature.
