We’re hosting an Arcshop on Circle Nanopayments this tomorrow!

Nanopayments is currently available for builders to test using Arc Testnet.

This session is focused on the mechanics behind gas-free, microdollar USDC payments.  The minimum payment allowed is One Microdollar - 1/ one millionth of a dollar ($0.000001).  It does this using x402, HTTP 402 payment flows, offchain payment authorizations, and Gateway batched settlement.
