What is USDC stablecoin?
USDC (USD Coin) is a dollar-pegged stablecoin issued by Circle, fully backed 1:1 by cash and short-duration US Treasuries held in regulated institutions. Every USDC token equals one US dollar, with monthly attestations published by Circle. USDC runs on multiple blockchains including Ethereum, Polygon PoS, Base, and Tempo, with sub-second settlement and zero gas fees when used via MoltPe. For AI agent payments, USDC is the standard rail because it is dollar-denominated (no forex exposure), programmable, and regulated. MoltPe is AI-native payment infrastructure that gives AI agents isolated wallets with programmable spending policies for autonomous USDC stablecoin transactions.
The short version
- 1:1 dollar peg: Each USDC is backed by one US dollar of cash and short-duration Treasuries held by Circle in regulated financial institutions, attested monthly.
- Issuer: Circle Internet Financial, a US-regulated issuer that publishes transparency reports and monthly reserve attestations by a major accounting firm.
- Chains: Live on Ethereum, Polygon PoS, Base, Tempo, Solana, Avalanche, and others — MoltPe supports Polygon PoS, Base, and Tempo for sub-second settlement.
In more detail
A stablecoin is a blockchain-native token designed to hold a stable value relative to a reference asset. USDC references the US dollar. Circle issues one USDC when a user deposits one US dollar and burns one USDC when a user redeems it for a dollar. The reserve sits in cash and short-duration US Treasury bills held at regulated custodians — it is not invested in risky or illiquid assets. That structural design is what keeps the peg tight: in normal conditions, USDC trades within fractions of a cent of $1.00.
For developers and AI agents, USDC is attractive for reasons that have nothing to do with crypto speculation. It is dollar-denominated, so there is no forex exposure when an agent in India pays an API in the US. It is programmable, so payments can be conditional, metered, or streamed. It settles in seconds rather than days, so real per-call pricing becomes viable. And because it runs on public blockchains, any service can accept it without integrating with a card network or bank partner.
MoltPe uses USDC as its single payment rail so agent-to-agent, agent-to-API, and human-to-agent flows all speak the same currency. When your agent pays an x402 endpoint, that payment is a USDC transfer on Polygon PoS, Base, or Tempo, confirmed on-chain in roughly 500 milliseconds with zero gas fees passed on to you.
