USDC

USDC is a stablecoin issued by Circle. It’s pegged to the US dollar — 1 USDC = $1, always. Unlike ETH or other cryptocurrencies, USDC doesn’t fluctuate in value. When an agent pays $0.001, you receive $0.001. No volatility, no FX risk, no conversion needed. USDC is one of the most widely held and trusted stablecoins, with over $40B in circulation and deep liquidity across every major exchange.

Base

Base is a Layer 2 blockchain built by Coinbase on top of Ethereum. It inherits Ethereum’s security while dramatically reducing cost and increasing speed. Why Base for micropayments:
PropertyValue
Transaction finality~1 second
Gas cost per transaction< $0.001
USDC supportNative
Reliability99.9%+ uptime
A $0.001 payment costs less than $0.0001 in gas. This makes sub-cent micropayments viable in a way that wasn’t possible on Ethereum mainnet.

Why this combination works for agent payments

AI agents make hundreds or thousands of API calls. Traditional payment rails can’t support this:
  • Credit cards — require human authorization, chargebacks, monthly billing cycles
  • Stripe — $0.30 + 2.9% minimum fee makes micropayments uneconomical
  • Crypto on Ethereum mainnet — gas fees exceed the payment value at small amounts
USDC on Base solves all three: instant, programmable, near-zero fees, stable value.

Wallets

Your MonkePay wallet is a Coinbase CDP wallet provisioned automatically when you create your account. It receives USDC from every agent payment. You don’t manage private keys — MonkePay handles custody. Your payout address is your personal wallet where you withdraw your balance. This can be any EVM wallet — MetaMask, Coinbase Wallet, a hardware wallet, or any address you control. Agent wallets are wallets held by the agent making payments. The agent needs USDC on the same network as your MonkePay account. See For AI Agents for how agents fund and use their wallets.
