My [login to view URL] dApp authenticates users with Privy, then hands control to the Polymarket Safe-SDK to spin up a personal Safe so they can transact. The hand-off is where everything breaks: Privy reports a successful sign-in, yet the Safe either never deploys or the SDK returns an undefined address, so the front-end is stuck with no signer to work with. I’m convinced the snag sits inside the Safe deployment logic, not the Privy auth itself. The app is already wired for the Polymarket SDK, [login to view URL], and wagmi, so I’d like you to trace the failure path, patch whatever is blocking the deployment, and hand back a clean, reproducible flow. Deliverables • A working sign-in → Safe deployment → address retrieval sequence running locally and on testnet • Inline comments or a short README outlining what broke and how you fixed it • Confirmation that subsequent contract calls pick up the newly created Safe without manual refreshes or hacks Acceptance criteria: after connecting with Privy, the console should log a valid Safe address, the UI should show wallet balance/actions, and no undefined references should surface across page reloads. I can share the repo, .env configs, and current stack (Next 13, React 18, Privy SDK, Polymarket Safe-SDK, ethers 6). If you’ve wrestled with Safe factories, async race conditions, or Privy session hand-offs before, you’ll feel right at home.

Hello there, I have got 9+ years in full-stack + Web3, and I can check the exact “Privy signed-in but Safe address is undefined” path, fix the async/race condition (or Safe factory init mismatch), and make the flow reliable across reloads. 1 - Which chain/testnet are you deploying the Safe on? 2 - Are you creating the Safe right after onAuthSuccess, or waiting for Privy’s embedded wallet provider/signer to be fully ready? Let's connect over chat to have in-depth discussion on it Vipin Sharma

I can debug and fix the Privy → Polymarket Safe-SDK hand-off so Safe creation completes reliably and returns a usable signer every time. What I’ll Do Trace the Safe deployment flow after successful Privy auth Identify where the Safe-SDK breaks (factory init, async race, provider/signer mismatch, or chain context) Fix the deployment so a valid Safe address is returned deterministically Ensure wagmi / ethers pick up the Safe signer without reloads or hacks Verify the flow locally and on testnet Deliverables Working sign-in → Safe deploy → address retrieval sequence Console logs show a valid Safe address immediately after auth UI reflects balance and actions using the new Safe Short README or inline comments explaining what broke and why the fix works Why Me Experience debugging Safe factories, async race conditions, and auth → signer hand-offs Comfortable with Next 13, React 18, Privy SDK, Safe-SDK, ethers v6, wagmi Once repo and env access are shared, I can pinpoint the failure path quickly and return a clean, reproducible flow.
