EEZ Tests 0.001 ETH Atomic Transfer Between Ethereum L1 and L2

The significance here is less the amount than the mechanism: atomicity across L1 and L2 is the plumbing Ethereum's rollup-centric roadmap has largely left to bridges and intermediaries, and a working single-transaction flow would change who bears settlement risk in that handoff. It matters most to rollup teams, bridge operators and anyone whose current cross-domain assumptions rest on external relayers. Whether this moves beyond a contributor-run test into something other teams can reproduce and build on is the open question.
