Polymarket Safe Auth Fix : safe deployment and approval overall flow for user trading

Job ID: 40160180

Budget: $30 – $250 USD

I have a Next.js-based dApp that relies on Privy for onboarding and Polymarket’s Safe deployment flow to spin up user safes once they connect. Right now the process falls apart at the authentication stage: after Privy signs the user in, the Safe either never deploys or returns an undefined address, blocking any further interaction.

What I need is a clean, working end-to-end flow that:

• authenticates the user through Privy,
• deploys a Polymarket Safe tied to that session, and
• returns the correct Safe address so subsequent contract calls succeed.

The bulk of the work sits inside the user authentication layer—getting the Privy session, wallet connection, and Safe SDK to play nicely together. If you have experience with Next.js, web3-modal / wagmi (or similar), Privy, and Gnosis/Polymarket Safe tooling, you’ll feel right at home.

I’ll hand over the GitHub repo, environment variables, and a short loom video showing the exact failure. Deliver back the patched code, brief commit notes, and a quick explanation of what broke and how you fixed it.
