A
- ADL (Auto-Deleveraging)
A last-resort risk mechanism that closes profitable opposing positions when the insurance fund cannot cover a liquidation. BULK describes ADL as a 'rare event' that triggers only when the insurance fund is insufficient.

The distribution of 30% of the BULK token supply to early users, the same allocation structure as Hyperliquid's $7B+ HYPE airdrop. Eligibility is gated by Aura points, trading activity, and BulkSOL holdings.
Read the full article → See also: Aura Points , Tokenomics- ALO (Add Liquidity Only / Post-Only)
An order type that will only rest in the order book as a maker. If the order would cross the book and take liquidity, it is cancelled instead.
Read the full article → See also: Order types , Maker fees- Aura Points
BULK Exchange's loyalty and activity metric. Aura accumulation is the most heavily-telegraphed input into the BULK token airdrop allocation. The mechanics page is listed as "coming soon" in the official docs.

B
- BIP-1 (BULK Improvement Proposal 1)
The first BULK Improvement Proposal. Specifies permissionless perpetual market creation — any wallet can deploy a new perp market without exchange approval, with risk isolated per market via listing bonds and pluggable oracles.
Read the full article → See also: Permissionless Perps- BULK
The native token of the BULK Exchange protocol. 30% of supply is allocated to community distribution. Used for governance and value capture from exchange trading fees.
Read the full article → See also: Tokenomics , TGE- BULK Exchange
A decentralized perpetuals DEX operating as an L0 execution layer alongside Solana. Targets 5–20ms matching latency within regional validator clusters, uses leaderless BFT consensus, and enforces fair ordering that makes front-running mathematically impossible within a batch.
Read the full article → See also: BULKBFT , Fair Ordering , BULK Net- BULK Net
The L0 execution layer that BULK Exchange runs on. Operates in parallel to Solana, using Solana for settlement and stake inheritance while running its own consensus and matching for sub-second execution.
Read the full article → See also: BULKBFT , L0- BULKBFT
A leaderless Byzantine fault-tolerant consensus mechanism. No single validator controls what transactions enter a batch. The fast path achieves agreement in 2 message delays — the theoretical minimum for BFT agreement.
Read the full article → See also: Consensus , Fair Ordering- BulkSOL
A Solana liquid staking token (LST) that earns four yield streams simultaneously: base Solana staking yield, MEV tips, BULK Exchange trading fee revenue share, and Aura point accumulation toward the airdrop.

C
- CLOB (Central Limit Order Book)
BULK uses a fully on-chain deterministic CLOB. Every validator produces identical output from the same input without communication during execution — the opposite of AMM-style pricing.
- Conditional Orders
Orders that trigger off market state, not user action. BULK supports stop-loss, take-profit, trailing stops, range orders (OCO), and on-fill triggers — all running without manual intervention.
Read the full article → See also: Order types- Cross-Margin
A margin mode where all positions in an account share a single margin pool. BULK Exchange uses portfolio cross-margin by default with correlation-adjusted effective notional.
Read the full article → See also: Portfolio Margin , Isolated Margin
D
- Deterministic Execution
A property of BULK's matching engine where every validator processes the same input and produces byte-identical output. Pre-flight checks, execution, and state updates run on all validators in parallel without communication.
Read the full article → See also: Matching Engine- Drift Protocol
A Solana-native perpetuals exchange running as standard Solana programs at 400ms block times. Compared to BULK's 5–20ms L0 execution layer in our deep-dive comparison.
- dYdX
A Cosmos app-chain perpetuals exchange. Compared to BULK Exchange (which runs as a Solana-aligned L0) in our comparison covering composability, liquidity, and governance speed.
E
- Exponent Finance
A lending protocol used in the BulkSOL yield stack — depositors lend BulkSOL or borrow against it to layer additional yield onto the base staking position.
Read the full article → See also: Loopscale , Yield stack
F
- Fair Ordering
BULK Exchange's 4-layer mechanism that makes front-running mathematically impossible within a single batch. Combines Fisher-Yates shuffle, leaderless admission, structural defenses, and real-time matching stack rules. No other perp DEX has documented all four layers.
Read the full article → See also: MEV , BULKBFT- Fisher-Yates Shuffle
The randomization algorithm BULK uses to shuffle order arrival positions within a batch. Cannot be front-run because the order is determined after admission, not before.
Read the full article → See also: Fair Ordering- Follower Mode
An SDK primitive that lets HFT builders subscribe to a chosen validator's pre-consensus stream and react to fills 2–5ms earlier than consensus-confirmed fills.
Read the full article → See also: HFT , SDK- FROST (Threshold Signatures)
The threshold signature scheme used in BULK's validator key management. Ensures that no single validator (or small subset) can move user funds — signatures require a threshold of the validator set.
- Funding Rate
The mechanism that tethers perpetual futures prices to spot. Positive funding means longs pay shorts; negative means shorts pay longs. Settled continuously on BULK Exchange.

G
- Genesis Phase
The first 30 days of BULK Exchange mainnet. Features 0 bps maker fees as a launch incentive. After Genesis Phase ends, standard maker/taker tiers apply.
Read the full article → See also: Fees , Mainnet
H
- HFT (High-Frequency Trading)
BULK supports HFT integration via the client SDK, follower mode, and the Alpha Program (7.5% of taker fees rebated to qualifying market makers).
Read the full article → See also: SDK , Market Making- Hyperliquid
A purpose-built perpetuals L1. The most direct competitor to BULK Exchange. See our full comparison: latency, margin efficiency, community allocation, fair ordering.
I
- Insurance Fund
A pool that backs liquidations on BULK Exchange. Funded by liquidation fees and protocol revenue. When insufficient to cover a liquidation shortfall, ADL is triggered.
Read the full article → See also: ADL , Liquidations- IOC (Immediate-Or-Cancel)
An order type that fills as much as possible immediately and cancels any remaining quantity. Cannot rest in the book.
Read the full article → See also: Order types- Isolated Margin
A margin mode where each position has its own dedicated margin pool. Available on BULK Exchange for traders who want to bound the risk of a specific position.
Read the full article → See also: Portfolio Margin , Cross-Margin
J
- JitoSOL
A Solana LST that captures MEV through Jito's auction system. Often compared to BulkSOL — both earn base staking + MEV, but BulkSOL adds exchange revenue share and airdrop accrual.
L
- L0 (Layer 0)
An execution layer that operates alongside an L1 (in BULK's case, Solana). BULK Net runs its own consensus and matching for sub-second execution while inheriting Solana's settlement and stake.
Read the full article → See also: BULK Net- Leaderboard
The public ranking of BULK Exchange traders by realized PnL, volume, and Aura points. Live at early.bulk.trade. Likely feeds into the airdrop multiplier as the highest-fidelity public record of pre-mainnet engagement.
Read the full article → See also: Aura Points , Airdrop- Leaderless Consensus
A consensus design where no single validator proposes blocks. BULKBFT uses leaderless consensus to eliminate the censorship vector that single-leader systems have.
Read the full article → See also: BULKBFT- Liquidation Optimizer
BULK's liquidation engine. Runs a 100-cycle optimizer that skips positions providing hedging benefit, targeting margin recovery with minimal portfolio disruption — instead of naively closing the worst position first.
Read the full article → See also: ADL , Insurance Fund- Loopscale
A Solana borrowing protocol used in the BulkSOL loop strategy. Users deposit BulkSOL as collateral and borrow SOL to acquire more BulkSOL — compounding yield with leveraged exposure.
Read the full article → See also: Trilly Loop , Yield stack- LST (Liquid Staking Token)
A tokenized representation of a staked position. BulkSOL is the LST issued by BULK; JitoSOL, mSOL, and bSOL are competitors.

M
- Maker / Taker Fees
BULK Exchange charges 2.2–3.5 bps taker fees, with maker rebates at higher tiers. 0 bps maker during Genesis Phase. No PFOF, no hidden spread costs.
Read the full article → See also: Genesis Phase- Margin Calculator
The live tool at early.bulk.trade that shows portfolio margin requirements, effective leverage, and liquidation prices in real time for any position set.
Read the full article → See also: Portfolio Margin- Matching Engine
The core component of BULK Exchange that turns submitted orders into fills. Deterministic, validator-replicated, runs in parallel across the validator set with byte-identical output.
Read the full article → See also: CLOB , Deterministic Execution- MEV (Maximum Extractable Value)
Value extractable by reordering, inserting, or censoring transactions. BULK's fair ordering system makes intra-batch MEV mathematically impossible. BulkSOL captures inter-batch MEV via validator infrastructure.
Read the full article → See also: Fair Ordering- Minisketch
A set-reconciliation protocol BULK uses for orderbook delta propagation between validators. Bandwidth stays flat regardless of update frequency — O(d) complexity.
Read the full article → See also: Matching Engine
N
- Noise Protocol
The encrypted-channel protocol BULK uses for client-to-validator communication. Combined with AEGIS-128L for the symmetric layer. Same primitive WireGuard uses.
O
- Order Types
BULK Exchange supports six base order types: market, limit, IOC, ALO (post-only), reduce-only, and trigger orders.
Read the full article → See also: ALO , IOC , Conditional Orders
P
- Permissionless Perps
Perpetual markets that anyone can list onchain without exchange approval. BIP-1 specifies the mechanism on BULK — the "Uniswap v2 moment" for derivatives.
Read the full article → See also: BIP-1- Portfolio Margin
A margin model that evaluates an entire account as a single risk unit, using correlation-adjusted effective notional. BULK's 9-regime HMM achieves up to 70% margin efficiency on hedged positions vs naive per-position margin.
Read the full article → See also: HMM , Cross-Margin
Q
- Quality Score
BULK's replacement for naive per-second rate limits. Tracks cancel-to-fill ratio, toxic flow indicators, and spam patterns per-account. Affects fee tier, market maker eligibility, and validator inclusion priority.

R
- Referral Program
Listed as 'coming soon' in the official BULK docs. When launched, will let referrers earn from the trading fees of traders they refer.
S
- SDK (Client SDK)
BULK's open-source client library. Connects directly to the L0 execution layer (no REST gateway), signs orders client-side, and exposes orderbook subscriptions, fill streams, and follower mode.
Read the full article → See also: Follower Mode- Sub-Accounts
BULK Exchange supports up to 64 sub-accounts per master wallet, each with independent margin and PnL. Volume aggregates under the master wallet for fee tier calculation.
T
- Testnet
BULK's pre-mainnet environment. A full exchange simulation that ran the $50k paper trading competition (ended May 28, 2026) and accumulates Aura points toward the airdrop.
- TGE (Token Generation Event)
The launch of the BULK token. Confirmed: 30% community allocation. Genesis Phase trading window with 0 bps maker fees runs for the first 30 days of mainnet.
Read the full article → See also: Tokenomics , Genesis Phase- Titan Exchange
The primary venue for swapping SOL into BulkSOL on Solana. First step in the BulkSOL yield stack.
Read the full article → See also: BulkSOL , Yield stack- Trilly Loop
The full BulkSOL → Exponent → Loopscale yield loop. Deposit BulkSOL, borrow SOL against it, swap to more BulkSOL, repeat. Compounds the four BulkSOL yield streams with leveraged exposure.

V
- Validators (BULK)
BULK validators run alongside standard Solana nodes, sharing identity keys and stake. 20+ independent operators represent ~5% of Solana total stake. Validators earn 12.5% of all BULK Exchange trading fees plus standard Solana rewards.
Read the full article → See also: Validator Rewards , Validator Setup
Y
- Yield Stack
The composable set of protocols that BulkSOL plugs into: Titan (swap), Exponent (lending), Loopscale (leveraged borrowing). Each layer adds yield streams onto base BulkSOL holding.
