The Long Tail of Blockchains Turned Out to Be the Main Channel

Summary

Michelle DG leads with the number that upends a three-year assumption.

Ethereum was the most-used single chain on SimpleSwap in the first half of 2026, at 31.0% of swaps — but everything outside the four biggest chains accounted for 71.4%.

“The comfortable assumption is that small chains carry small amounts, and it is wrong.”

Key Takeaways

  • Ethereum led as a single chain at 31.0% of swaps; chains outside the big four carried 71.4%.
  • Cross-chain swaps held 90.3-93.3% every month while the spot market roughly halved.
  • Value per swap on small chains sits at 1.04 of average — not the small amounts usually assumed.
  • Rubic's independent data shows TRON rising from 11.9% to 38.4% of its cross-chain money.
  • The two datasets disagree on the long tail, and the article reports that rather than smoothing it over.
  • With nine swaps in ten crossing a boundary, reach matters more than listing count.
