BULK's Pre-Deposit Campaign Is Closed — What Happened and How to Get Mainnet Access

If you’re looking for how to pre-deposit USDC on BULK: that window closed September 5, 2026. Mainnet launched, and every pre-deposit converted automatically to trading margin. This page now covers what happened, and how to get access to mainnet trading today.

What the Pre-Deposit Campaign Was

From June 1 to September 5, 2026, BULK ran a pre-deposit campaign: park USDC in the protocol before trading went live, in exchange for AURA points toward the 30% community token allocation at TGE.

The campaign paid out 1,000,000 AURA every Saturday, weighted by USDC deposited × time held, with the majority going to pre-depositors. Total deposits reached roughly $40M+ before the campaign closed. Depositors who held through the final weeks also received a starting allotment of weekly access codes (5-15, based on whether their deposit exceeded $1,000 or $100,000) for the invite-only mainnet period.

What Happened on Launch Day (September 5, 2026)

Predeposits and withdrawals were paused from 8-9am UTC while BULK executed the conversion from predeposits to margin on the backend. By 7:04am ET, the network upgrade was complete: “All pre deposits are now converted to BULK network margin.” Trading opened invite-only at 9am EST.

No action was required from depositors — the conversion happened automatically, in place, for every account.

How to Get Mainnet Access Now

Mainnet is invite-only. There are two ways in:

You already pre-deposited. You have day-1 access automatically, plus a starting weekly batch of access codes. Go to app.bulk.trade, connect your wallet, and your converted margin is ready to trade.

You didn’t pre-deposit. You need a referral link, or an access code from someone who has one — access codes automatically attach a new referral to the referrer’s link. New traders start with zero codes and earn one more per $1M in trading volume, so the fastest way in is asking an active trader for an invite.

What Changed From Pre-Deposit to Mainnet

Withdrawals Still Work the Same Way

Your converted margin is withdrawable at any time from your BULK account, exactly as your pre-deposit was. The core trust signal that made pre-deposit legitimate — capital under your control, verifiable on-chain, never locked — carries forward unchanged into mainnet.

What to Do Next

1. Get access — grab a free access code or use our referral link, or use your existing day-1 access if you pre-deposited.
2. Trade during the Genesis Phase — 0 bps maker fees run through roughly October 5, 2026.
3. Hold or acquire BulkSOL — now earning 12.5% of live exchange fees.
4. Trade volume into access codes — grow your own referral network with codes earned from trading. See the referral code guide for the full mechanics.
