## Source summary

BIS Working Paper No 1377 uses granular Bitcoin, Ethereum and Tron data to show that common measures of cryptoasset and DeFi activity depend heavily on classification and aggregation choices. The authors report that measured Bitcoin transaction value can vary by as much as a factor of six, classify 13 million active smart contracts including about 1.4 million tokens, and find trading activity concentrated around stablecoins. They also find that the same stablecoin can serve different purposes across chains, with Ethereum activity more closely tied to smart-contract interaction and Tron activity more often held outside smart contracts.

## Why it matters

The paper is a measurement warning for stablecoin and on-chain payment intelligence: transparent ledger data does not automatically map to economic activity, transaction purpose or comparable payment volume. Its toolkit argues for explicit assumptions, technical classification and disaggregation before drawing market conclusions. This is research, not a payment-product launch or operating result. The findings depend on the selected chains, Mercurius data and the authors' methods, and BIS states that working-paper views belong to the authors rather than necessarily to the institution.

## Key numbers

- **Maximum divergence in measured Bitcoin transaction value:** factor of 6
- **Active smart contracts classified:** 13 million
- **Token contracts within the classified set:** about 1.4 million
- **Public blockchains examined:** 3 (Bitcoin, Ethereum and Tron)
