BULK Season 1: What 4,356 On-Chain Depositors Actually Look Like at 72 Hours

72 hours into BULK Season 1, the BULK program vault holds $14,206,438 USDC across 4,356 active on-chain depositor accounts. Most analyses of the leaderboard stop at the API. We went deeper — pulling directly from the Solana program to find the numbers that don’t show up in the dashboard.

This is the full breakdown.

The Real Depositor Count vs. the API Number

The BULK API reports 4,575 total wallets. The on-chain reality is 4,356 active predeposit accounts.

The difference — approximately 219 wallets — represents depositors who entered the program and then fully withdrew. They appear in the API’s historical totals but hold no active on-chain state. They are earning zero AURA this week.

Every depositor who stays generates a 681-byte account in the BULK program marked with the predepos discriminator. Each Saturday snapshot reads these accounts. If your account is closed, you are not in the snapshot.

The practical point: Withdrawing entirely from the program removes you from weekly AURA allocation. Withdrawing partially reduces your USDC × time calculation proportionally.

The Vault: Where the USDC Actually Sits

The BULK program vault address is 7Wpp33Dn5KKUFjaij4zKYy1XZ9kdBtHjUatAT6NcjjGt. This is a program-derived address (PDA) owned by the BULK smart contract (BULK2CNYn3mbgfYXEXiBBFxmmDChznpjQ4oRfce8w6R4).

The vault’s USDC token account (HwdwwKH1tMXo7ggTKcA5cdQrpcgqSoVib2eQh3BiyEQL) held $14,206,438.45 as of June 3, 2026 at 13:00 UTC. Deposits are arriving continuously — transactions settle to the vault every 20–120 seconds throughout the trading day.

The gap: The API shows $14.8M deposited total. The vault holds $14.2M. The $600K difference is net withdrawals since launch — funds that entered the program and then left. TVL is growing, but not all capital that touched the program is staying.

One technical note: the BULK smart contract is deployed as a BPF upgradeable program. The team holds an upgrade authority key and can modify the contract logic before TGE. This is standard practice for pre-launch protocols but worth knowing.

The Two-Axis System Most Depositors Haven’t Found Yet

There are two separate competitions running simultaneously in BULK Season 1. Most participants are only aware of one.

Axis 1: Deposit rank — ranked by USDC × time held. This is the leaderboard everyone can see. It rewards deposit size and early entry. Whales compete here.

Axis 2: Aura rank — a separate scoring system based on retroactive protocol history across Exponent Finance, Loopscale, testnet participation, alphanet access, and Discord role status. This window is permanently closed. The retroactive snapshot was May 31, 2026.

The dataset makes this gap visible. The $1M deposits at ranks 2 and 3 have zero Aura. A wallet with $396 deposited sits at global Aura rank 25 — entirely from retro_exponent accumulation through Exponent Finance. The TGE allocation formula is not published, but if both axes feed into it, the deposit-only whales are competing with one hand tied.

The Held-Time Moat Is Already Closed

The gap between rank 1 and rank 100 is 97% of held-time. Anyone depositing today cannot close that gap — they can only compete on raw deposit size. The USDC × time formula means every hour of existing held-time compounds forward. New entrants start from zero.

What this means for existing holders: Your oldest deposit accounts are your most valuable assets, not your largest ones. A wallet with 100K held-time hours and $10K deposited has a structural advantage over a wallet with zero held-time and $100K deposited — on the time axis, which is closed to new competition.

The Aura Category Rarity Map

The retroactive Aura categories and their rarity in the top 2,000 depositors:

retro_exponent is the dominant value driver. Wallets with high exponent scores hold the most Aura. This category reflects liquidity provision or trading activity on Exponent Finance before the snapshot — the highest-signal retroactive qualifier in the dataset.

retro_roles is the rarest. Two tiers exist: 309 (OG role) and 617 (Contributor role). Fewer than 15 wallets in the visible top 2,000 hold this category. Every wallet that does has a global Aura rank that outperforms its deposit rank by a significant margin.

What the Withdrawal Data Shows

5.8% of deposited USDC has already left the program within 72 hours. A pattern in the top 2,000:

• Full withdrawals (~219 wallets): Tested the system and exited. Zero AURA going forward. Done.
• Large-then-reduce (visible in mid-rank range): Deposited $100K, withdrew $90K, kept $10K. These wallets ran the math on return vs. lockup and decided a smaller position was sufficient.
• Near-complete exits: Rank 343 deposited $101.2K and withdrew $100K, keeping $1.2K. Effectively stress-testing the protocol mechanics.

The interpretation: some portion of the whale deposits in the first 72 hours were not committed capital — they were exploratory. Wallets that tested liquidity mechanics and determined the AURA return on large pre-deposits doesn’t justify the opportunity cost have already rebalanced down. This is information the deposit leaderboard alone does not show.

Coordinated Wallet Clusters — A Sybil Risk Signal

In the 85–100 rank range, a cluster of wallets deposited $20–21K each within a two-hour window on June 2 at 12:00–13:30 UTC, each with exactly one referral. Near-identical deposit amounts, near-identical timing, near-identical referral counts.

This is the kind of behavioral pattern that Hyperliquid’s sybil detection was designed to catch. BULK’s team has on-chain access to the same data — deposit timestamps, referral linkages, wallet funding sources, and behavioral patterns are all visible in the program accounts.

For individual depositors: differentiated timing, unique Aura history, and varied deposit behavior are the signals that make a wallet look like a real user rather than a coordinated operation.

The Referral Economy Is Underused

2,130 total referrals claimed across 4,575 wallets is a 0.47 referral-per-wallet average. The referral program is barely being utilized relative to its potential.

The top referrer in the visible dataset has 41 referrals on a $26K deposit — no retroactive Aura, no depositor-rank advantage. The referral lever is the one axis where consistent effort compounds without requiring either capital or protocol history.

None of the top 50 depositors by rank appear to be running active referral funnels. That is the unclaimed lane.

The Bottom Line

At 72 hours, the BULK Season 1 dataset reveals three independent competition tracks:

1. Deposit size — a whale game, still open, dominated by the earliest large depositors
2. Held-time hours — moat built by the oldest accounts, mathematically unrecoverable for new entrants
3. Retroactive Aura — permanently closed, window was May 31, rewards protocol history that new capital cannot purchase

The depositors with all three are positioned across every allocation axis simultaneously. The depositors with only one — pure capital, no time, no retro — are fighting the hardest battle with the fewest tools.
