Tier 4 is for high-volume traders. It raises your daily AUD deposit, AUD withdrawal and crypto withdrawal limits to $1,000,000. This guide shows you how to request the upgrade in the Coinstash mobile app and what to expect.
Before you start
Your account must be at Tier 3 before you can request an upgrade to Tier 4. Tier 3 includes a completed Proof of Address — see How do I Upgrade My Account to Tier 3?
Details about your money: Tier 4 requires a Source of Funds/Wealth Declaration. Be ready to explain where your investment money comes from and how you built your overall wealth — for example, salary, inheritance, investment gains or business profits.

How to upgrade your account to Tier 4
Tap your profile image in the top right-hand corner.
Tap My Account.
Tap the Edit button.
Find the Unlock Tier 4 panel and tap Upgrade. A support chat window will open with a pre-filled request — tap the Send (up arrow) icon.
Our team will reply with a secure link to the Source of Funds/Wealth Declaration. Complete the declaration with details of where your investment capital comes from.
What happens next
Once the declaration has been completed, our onboarding team will review the information and upgrade your account to Tier 4. We aim to process all Tier 4 upgrade requests within two business days.
Australian regulations require us to collect this declaration before allowing high-value movements on the platform. It's a standard part of our Trust and Compliance framework.
Troubleshooting
I can't see the Unlock Tier 4 panel. You need to be on Tier 3 first. Check your current tier under My Account.
I haven't received the declaration link. Make sure you sent the pre-filled chat message. Our team replies in that same chat, so check your messages in the app.
It's been more than two business days. Our team may need more information about your declaration — check your chat and email, then contact us if you haven't heard back.
