BULK mainnet launched September 5, 2026. Pre-deposits converted automatically to trading margin, invite-only trading opened at 9am EST, and the Genesis Phase (0 maker fees) is live through roughly October 5.
The BULK Exchange paper trading competition ran May 19–28, 2026 with $50,000 in prizes, paid out May 29. The ranking formula changed mid-competition after gaming was discovered, and 27 wallets were banned for bot abuse. This page covers what actually happened and how to use the testnet now.
BULK Exchange charges 2.2–3.5 bps taker and offers maker rebates up to −2.0 bps. Genesis Phase gives every trader zero maker fees through ~October 5, 2026 (30 days from the September 5 mainnet launch). No liquidation fees, no PFOF, no hidden spread costs.
BULK mainnet is live and invite-only. Referral links persist from Season 1, but a new referral also needs an access code — earned by pre-deposit tier or by trading volume, resetting weekly.
BULK's Genesis Phase waives maker fees entirely for the first 30 days of mainnet. Every day you trade after this window closes, you're paying a fee you could be paying zero on right now.
