USDC is the de-facto unit of account for agent payments: a dollar-pegged stablecoin available natively on Base, Solana, Ethereum and more. Pricing in dollars instead of a volatile token keeps per-request metering sane, and Circle’s issuance makes USDC the default settlement asset for x402 facilitators.
Below are the USDC-focused projects tracked in the directory — accept, send and convert USDC in x402 flows.
The USDC category right now
Of the 223 USDC projects in the index, 8 have real traction (100+ stars) and 78 have none yet. ClawRouter is the reference point at 6,661★. The median is 1★ — useful context before you pick a dependency from this list.
If you are choosing a stack, note that TypeScript (47%) and Python (17%) carry most of the USDC work, much of it from @armory-sh, azeth-protocol, kmatthewsio. Projects tag themselves with ai-agents, base, usdc more than anything else.
Freshness matters more than star count in a category this young: 84 projects shipped code in the last month, 132 in the last quarter, and 14 have not been touched in over a year. In short, activity is uneven — check the last-commit date before adopting. Newest addition: solcex-autonomous-vanguard (2026-06).
