How Blockchain Data Represents Stablecoin Activity

Public blockchains are transparent by design: every transfer, timestamp, and amount is visible. However, blockchains record how value moves, not why it moves. Wallets are pseudonymous, transaction metadata is minimal, and economically distinct actions can look identical at a transaction level. By contrast, traditional payment systems embed rich contextual metadata—merchant type, transaction purpose, reversals, settlement status—which allows intent to be directly observed.

Due to these dynamics, raw blockchain metrics such as total transfer volume or transaction count materially overstate meaningful economic activity. They capture settlement mechanics rather than use cases, and cannot, on their own, distinguish payments from trading, treasury movements, or protocol operations. The core analytical challenge is therefore not visibility, but interpretation.

Pattern Identification as the Basis for On-Chain Analytics

Because economic intent is not explicitly encoded on-chain, pattern identification is the primary enabler of stablecoin analytics. As with traditional transaction monitoring, classification relies on repeatable behavioral signals rather than declared purpose. These include transaction size, frequency, flow symmetry, counterparty diversity, and temporal consistency

To operationalize this approach, we partnered with Allium, a blockchain data provider with coverage across more than 1,000 stablecoins and multiple major blockchains, to develop a conservative, behavior-based framework for classifying stablecoin transfers by economic use case. One limitation of our approach is that it only captures activity that settles on public blockchains. Large categories of stablecoin usage occur predominantly off-chain and are therefore not observable, including:

• Centralized exchange internal activity: Overwhelmingly spot and derivatives trading settled on internal ledgers; peer-to-peer transfers exist but are marginal.

• Crypto card payments: Transactions executed on card rails using custodial stablecoin balances, where on-chain data captures only issuer inflows and outflows, which should amount to about $15 billion in 2025 according to Artermis and Visa.

Because of these factors, our estimates should be interpreted as conservative relative to total stablecoin economic activity
