   Step 1

   Obtain a one-time access code, which the docs describe as the only way into BULK during invite-only mainnet

2. 2

   Step 2

3. 3

   Step 3

   Trade perpetuals to earn Trading AURA, which also places you in a weekly Challenger Series league

4. 4

   Step 4

   Check the weekly Gauntlet task announced each Saturday on the Challenger Series page

5. 5

   Step 5

   Track AURA and league standing in the BULK app

Where things stand

BULK is a perpetuals exchange that runs as a separate execution layer next to Solana. According to its architecture docs, each BULK validator runs a dedicated binary alongside a standard Solana validator, shares its identity keys and inherits stake weight from it. Order matching, consensus and the risk engine run on the BULK network, while custody, deposits and withdrawals settle in a Solana program. The docs state that the initial validator set represents about 5% of Solana stake across more than 20 operators.

Mainnet is currently invite-only. The referral docs say one-time access codes are the only way for new users to get in, with codes issued weekly to existing users based on pre-launch deposits and trading volume. BULK earlier ran a pre-launch deposit campaign, and deposit tiers from that campaign still determine how many weekly codes those users receive.

BULK uses AURA as its points unit. The docs we opened describe how AURA is earned and how it ranks traders, but say nothing about a BULK token, a conversion of AURA, or a snapshot. We therefore list BULK as potential, and treat any supply share quoted by third parties as unverified.

How AURA and the Challenger Series work

A fixed supply of 1,000,000 AURA is issued each week. Most of it is Trading AURA earned from trading activity, and 50,000 points (5% of weekly supply) go to a weekly Gauntlet, a task announced every Saturday and split pro rata by each trader's contribution to whatever metric that week's Gauntlet counts. The docs give an example in which a trader with 1% of weekly taker volume receives 500 Gauntlet points.

The Challenger Series, which started on October 10, 2026, ranks traders weekly by Trading AURA into leagues from Bronze to Challenger. Every league with Trading AURA earns AURA, and the top four leagues also share a prize pool funded by 12.5% of BULK net revenue, defined as trading fees minus maker rebates. Challenger receives 45% of that pool, Diamond 25%, and Platinum and Gold share the remaining 30%. The minimum claimable reward is $5. The regular season ends on December 5, 2026, followed by playoffs whose format has not been announced.

Market makers receiving tier 2 or higher maker rebates on any market in a given week are excluded from that week's leagues, prize pool and Gauntlet. Makers have a separate Alpha Program funded by 7.5% of taker fee revenue per 30-day epoch.

• 1,000,000 AURA per week, nothing extra minted for Gauntlets.
• Leagues reset weekly, so rank can move down as well as up.
• Prize pool is a share of net revenue, not a fixed amount.

Anti-farming rules and risks

The docs state that all rewards are subject to wash-trading and Sybil checks and that flagged accounts are excluded. The fee page also notes that self-trades between accounts under the same main account do not create qualifying volume. Detection methods are not published.

Taker fees start at 3.5 bps at the lowest 14-day volume tier. Because AURA rewards activity relative to everyone else, the cost of chasing a higher league can exceed any reward, especially at high leverage. BULK uses a novel validator-embedded design, which the docs explain in detail, and its Solana program was audited, but newer infrastructure carries technical risk regardless of audits.

The access-code system invites impersonation. Fake codes, cloned apps and fake airdrop checkers are common around invite-only launches. Use only bulk.trade and docs.bulk.trade, never share a seed phrase, and treat any BULK token claim page as fraudulent while no token has been announced.

What to take from this drop

BULK combines a points system with a revenue-funded weekly prize pool, so part of its rewards is paid out now rather than promised for later. The AURA side, which is what airdrop hunters usually care about, has no published link to any token.

On costs, BULK charges no separate liquidation fee; liquidation pricing instead includes market-impact and reserve adjustments. Fee tiers use the trailing 14 completed UTC days, aggregate the main account with its sub-accounts, and a fill cannot move itself into a lower tier. Validators receive 12.5% of trading fees. The first 30-day phase had no base maker fee, while the second phase introduces maker fees of up to 2.0 bps at the lowest tier, so makers should check which phase applies before planning a strategy.

If you can get an access code and want a Solana-settled order book, the Challenger Series gives measurable weekly rewards. Treat AURA as an unpriced extra, and keep risk within what you can afford to lose. We will update this page if BULK publishes token or AURA conversion details.
