3 · Deploy the deposit contract
The Polymarket deposit wallet is a smart wallet derived from its owner's signing address. Its address can be calculated before its contract is deployed, but the contract must exist on Polygon before wrapping or trading can work.
Sign in to Polymarket with the bot's wallet and complete its supported wallet setup flow. Confirm both the owner signing address and the resulting deposit wallet address. They are different addresses. Check that the wallet contract is deployed before proceeding to funding.
Polymarket's eligibility and regional restrictions apply to bots too. If the service is unavailable in your region, stop setup; a server or administrative endpoint does not change your eligibility.
