What a $0.04 agent payment actually costs on Base vs Solana
GetAgentCap team · published 9/17/2026
The two transfers we use in our own demo data moved $0.10 and $0.04 in USDC on Base. Base's gas at the time of those transactions ran a few cents in ETH — meaning the fee on the smaller payment was in the same order of magnitude as the payment itself. That ratio is the actual number to watch when you're routing high-frequency agent spend.
The demo numbers, not a benchmark
Our demo page shows two real, independently-verified USDC-on-Base transfers from the same sending wallet: $0.10 and $0.04, about eight minutes apart. We're not running a fee benchmark here — those are two data points, not a study — but they're real transactions, not made-up round numbers, and that matters when you're trying to reason about whether micropayments make sense at all.
Why network choice changes the math at this size
A $19.99 purchase barely notices a few cents of gas. A $0.04 agent-to-agent payment does — at the low end of what we see agents actually pay each other, fee overhead can rival or exceed the payment. This is why we track both Base and Solana: Solana's typical fees run closer to fractions of a cent, which changes whether sub-$0.10 payments are economical at all, versus Base where they're workable but the fee ratio is worth watching.
We haven't run a large enough sample across both chains to publish a real cost-per-payment comparison yet — that's the honest gap in this post. What we can say is that if your agents are making a lot of sub-$0.10 payments, the network fee line deserves its own column in your accounting, not a footnote.
What this means for your fleet
If your agents are paying out in the low cents range and doing it often, check which chain they're settling on before you assume the unit economics work. A $0.04 payment that costs $0.03 in gas is a different business than one that costs $0.0001.
