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 0x68185584ccb166806f7ed69996380f50ac06035b instead of the 4/12 manager — the admin is the EIP-1967 owner and can setManager, so it can grant solvers itself in one atomic batch.

Run: Transaction Builder app on the admin Safe → import the JSON below → 2 sigs → execute.

What the tx does

1. setManager(0x68185584…035b) — admin Safe temporarily becomes manager
2. addSolver(0x531636e6…7A37) — CoWSafeWrapper
3. addSolver(0x2E3fdEe2…9363) — CowFlashLoanWrapper v6
4. addSolver(0xFa5d3f85…6Af1) — solver EOA (calls wrappedSettle)
5. setManager(0xA03be496…4930) — restore the original 4/12 manager

Net effect: only the three solvers added; manager restored. Atomic.
