How Will Cross-Rollup Liquidity Standards (like UAT-20) Change the L2 Landscape?

[happysemicolon]

With dozens of L2s live, liquidity fragmentation across rollups is becoming a serious challenge.
Standards like UAT-20 propose unified cross-rollup token behavior to reduce fragmentation.
Has anyone experimented with or researched these standards, and how practical are they for real DeFi adoption?
I’d love to hear experiences or resources on early implementations.

UAT-20 is a research-proposed token standard using CRDTs and a two-phase commit protocol to unify ERC-20 liquidity across rollups, addressing fragmentation without altering base designs.
