Bring TWAP/JIT-funding scripts + cow-sdk 9.2.2 upgrade to main#17
Merged
Conversation
Follow-up to the TWAP-from-EOA PoC. Instead of moving the full TWAP sell amount into cow-shed up front, each part is pulled just-in-time from the EOA via the ComposableCowPoller contract, so capital stays in the user's wallet between parts. - New postTwapForEOAWithJitFunds script: a 1-wei sell=buy order carries a gasless post-hook that approves the Vault Relayer and creates the TWAP on cow-shed; the EOA approves the poller for the full sell amount and registers the JIT funding schedule. The watch-tower then pulls each part on demand. - Add a minimal ComposableCowPoller contract helper and its Gnosis address.
v9 is a modular re-architecture. Migrate the composable-cow TWAP-from-EOA scripts to it: - cow-sdk 9.2.2; add sdk-composable (Twap), sdk-cow-shed (CowShedSdk) and sdk-ethers-v5-adapter, which were split out of the main package. - Set a global provider adapter (EthersV5Adapter) — v9 reads it via getGlobalAdapter() for ABI encoding, and TradingSdk/CowShedSdk take it too. - TwapData amounts are now native bigint (were ethers BigNumber). - Add runtime peer deps: ajv, cross-fetch, multiformats, @openzeppelin/merkle-tree. - Drop the obsolete 6.0.0-RC.42 patch (its changes ship in v9).

What
Lands the stacked TWAP / JIT-funding work and the SDK upgrade onto
main. These reachedmainonly partially before: PR #12 was squash-merged directly tomain, while PR #14 (JIT-funded TWAP) and thecow-sdk9.2.2 upgrade were stacked onpost-twap-from-eoa/upgrade-cow-sdk-9and never propagated.Merges
upgrade-cow-sdk-9(the superset) intomain. Brings:src/scripts/composable-cow/postTwapForEOAWithJitFunds.ts(the missing JIT script)src/scripts/composable-cow/postTwapForEOA.tsupdates +cowShed.tshelpersrc/contracts/composable-cow-poller/@cowprotocol/cow-sdk6.0.0-RC.42 → 9.2.2 (package.json + yarn.lock), which also fixes the earlier package.json-vs-installed mismatchmain-only content (e.g.collateralSwapAave.tsfrom #12) is preserved.Conflict resolution
The divergence came from
mainhaving a squashed #12 vs the branch's unsquashed history. Resolved by taking the branch (9.2.2) versions ofpackage.json/yarn.lock/postTwapForEOA.ts, and unioningsrc/index.ts(keeps all imports;postTwapForEOAWithJitFundsis the active JOBS entry).Test plan
Note:
src/scripts/flash-loans/collateralSwapAave.tsstill has pre-existing type errors (unrelated to this merge; part of the collateral-swap work).
