Aerodrome Farming Made Up 90% of USDC Transfers in a Single Day, Analyst Claims

A new on-chain analysis is forcing a rethink of how the crypto industry reads stablecoin volume headlines. On Sep. 23, analyst RyeBlocks estimated that roughly 90% of the day’s reported USDC transfer volume — about 109 billion USD out of 121 billion USD — came not from payments, but from liquidity farming on Aerodrome, the flagship decentralized exchange of Coinbase’s Base network.

The finding, which RyeBlocks described as “inorganic farming,” leaves only about 12 billion USD of the reported daily total outside the activity the analyst identified. And even that remainder is not necessarily payments: the estimate simply does not establish what the remaining transfers were. The analyst also calculated that one-tick farming has generated roughly 75% of USDC transfer volume in the data measured since Aerodrome launched in August 2023, though the post links to a Dune analysis without fully spelling out the scope and filters behind the longer-term figure.

## What one-tick farming actually does

Aerodrome combines a Slipstream concentrated-liquidity design with traditional pools, rewarding eligible liquidity providers with AERO token allocations determined by weekly voting. In one-tick farming, a liquidity provider concentrates a position into a very narrow price range — a single tick. As those positions are managed, USDC moves through pool contracts repeatedly, and each movement is recorded as an on-chain transfer.

The result is a measurement problem: the value counted as moving on-chain can climb every time tokens change position, even when no purchase or payment to another person has occurred. RyeBlocks’ comparison concerns transfer records, not settled economic activity — and the finding does not, by itself, show any wrongdoing by Aerodrome or its users. Providing liquidity is a normal, legitimate exchange function.

The distinction matters because headline transfer totals are frequently cited as evidence of stablecoin adoption. If most of the volume is trading infrastructure cycling the same tokens through pool contracts, the payments narrative attached to those numbers needs to be treated far more carefully.

## Swaps and transfers are not the same thing

A separate datapoint illustrates how different measures describe different things on Base. In September, Aerodrome handled 557.1 million USD of tokenized-stock trades over a 30-day period — 76% of that category’s volume on the network, according to Token Terminal figures. That number counted completed swaps. RyeBlocks’ USDC figures count token transfers. The two totals describe fundamentally different activity and should not be combined, but together they show how much of Base’s on-chain footprint flows through one DeFi protocol.

## How data providers already handle the problem

Visa’s Onchain Analytics Dashboard, built with data partner Allium, draws exactly the distinction RyeBlocks is pointing at. Visa separates total stablecoin volume from an adjusted measure that strips out potential distortions from bots, high-frequency trading, routing and repeated internal movements within transactions. The dashboard also classifies transfers by use case, distinguishing payments for goods, services or person-to-person transfers from DeFi activity, exchange flows and trading. A USDC transfer into a liquidity pool is recorded on-chain without being classified as consumer payment activity.

In other words, the infrastructure to separate organic stablecoin payments from mechanical trading volume already exists — but raw transfer totals still dominate headlines, and analysts like RyeBlocks are working to expose how misleading those raw numbers can be when a single protocol’s farming mechanics dominate a network’s transfer log.

## Why it matters for the adoption debate

Stablecoin volume statistics have become a battleground for narratives about crypto’s real-world utility. Regulators, banks and payments companies routinely cite hundreds of billions of dollars in monthly stablecoin transfers as evidence that dollar-pegged tokens are displacing legacy rails. If a large share of that volume on a major network like Base is liquidity management rather than payments, the adoption story becomes more modest — and more honest.

The irony is hard to miss: Aerodrome’s success at attracting liquidity is itself a sign of Base’s DeFi traction. The protocol dominates the network’s activity because traders and liquidity providers choose to use it. But the same success inflates transfer metrics that get repurposed as payments statistics, and the industry now has a quantified estimate of just how large that distortion may be on a given day.

For DeFi watchers, the RyeBlocks analysis is also a reminder that Base and Aerodrome remain deeply intertwined. Coinbase built the network, Circle issues the USDC that dominates its pools, and Aerodrome — a fork of Velodrome, itself born from OlympusDAO’s ecosystem — captures the majority of its trading and farming activity. When one protocol’s incentive mechanics can move a global stablecoin volume chart by 90% in a day, analysts and journalists alike need better filters before declaring what stablecoins are actually being used for.
