x402 is an open, internet-native protocol developed by Coinbase that enables payments in stablecoins and other crypto assets. Like shared internet protocols that allow different systems to communicate reliably, x402 introduces a standardized framework for making payments across platforms.
x402 transaction size has significantly declined over time. As of January 21, 2026, the average transaction size is $0.06.
The fixed-fee structure of card and online wallet payments limits use for micropayments. The architecture of stablecoins, on the other hand, provides a model for economic viability for small-value transactions.
While Base leads by volume, Solana may emerge as the leading network for x402 transactions. Transactions below $0.10 are inhibited by Base’s average gas fee of $0.015, as 25% overhead costs are unsustainable for at-scale adoption.
Dexter leads all x402 facilitators by transactions as of January 21, 2026. The primary use of the protocol is for trading APIs, consistent with the theme of speculation as the initial PMF for new crypto use cases.
