Anyone using Binance Web3 / Agent ID for on-chain stuff without babysitting seed phrases?

Been looking at the .ai / Agent-wallet style flow where you claim an Agent ID, flip Developer Mode, and keep a little BNB for gas instead of juggling a cold seed for every tiny test. For people already in the BNB / Binance Web3 lane, the referral entry I use is: https://web3.binance.com/referral?ref=PIBCJYU1

Curious how others here handle it day to day — do you keep a separate research wallet, and how much BNB do you leave for routine gas? Not a call, just comparing setups. DYOR / NFA.
