EEZ two-composer deployment on 147.135.221.107 — issue report (2026-07-01)

Two-composer EEZ deployment on 147.135.221.107 — issue report

Chain: Chiado L1 (10200) + EEZ Rollup0 L2 (10201) • Registry 0xd3a59fc7…99317 • Composers C1 / C2 Date: 2026-07-01 • Updated: 2026-07-01 after live diagnosis with Edu

Correction to the original diagnosis of #1

The initial version of this report attributed the failing L1→L2 deposits to the two-composer bundle race described in eez-rollup0#20. That was wrong. After Edu identified the real cause on-chain and I re-tested, the actual behavior is described in the corrected #1 below. The two-composer race may still exist as a separate issue, but it is not what I was reproducing.

Safe Tx Builder JSON: whitelist CoW leverage wrappers (Gnosis staging) from 2/n admin

Safe Tx Builder JSON — whitelist CoW leverage wrappers + solver EOA (Gnosis staging)

Update 2026-06-11: added a third addSolver for the fresh solver EOA 0xFa5d3f85da8395D4562D18422cB27e032a676Af1 — the address that will actually call wrappedSettle. Wrappers alone aren't enough: the authenticator must also allow the caller. (JSON uses data: null so the Tx Builder decodes each call into readable setManager/addSolver entries instead of "Custom hex data".)

JSON for the Safe Transaction Builder to whitelist everything needed on Gnosis staging (authenticator 0x02073540567FA1EABcBf74C2F7E6F9029ca7d800) from the 2/n proxy-admin Safe
