The Velocity ecosystem: trading, liquidity and risks
A technical breakdown of the relaunched Drift Protocol: from execution mechanics to the insurance fund
The Velocity ecosystem: perpetual trading relaunched on Solana
Review summary (current as of August 2026)
Velocity is a decentralized perpetual exchange on the Solana blockchain created by the Drift Protocol team after the April 1, 2026 hack. The protocol was forked from the Drift v2 codebase and deployed as a new on-chain program with its own program ID, running in a closed beta with whitelist access. The settlement asset for all markets is USDT (the switch from USDC being a condition of the Tether credit line).
Key differences from its predecessor: a trimmed product set (perpetuals and Borrow & Lend only), the removed durable-nonce mechanism — the vector of the April attack — a tiered admin-key model (cold/warm/hot/pause) and an insurance fund 100% owned by stakers. There is no spot order book: spot markets exist solely for collateral and lending.
Timeline: from the hack to the relaunch
| Date | Event |
|---|---|
| April 1, 2026 | The Drift Protocol exploit: about $286M withdrawn across 31 transactions in roughly 12 minutes. The vector was multisig compromise via the durable-nonce mechanism — the Security Council signed transactions unknowingly. Investigators (ZachXBT, Elliptic, Chainalysis, TRM Labs) linked the attack to the Lazarus Group. |
| April 2026 | The Tether deal: a credit line of about $127.5M in exchange for switching the settlement asset from USDC to USDT. The recovery-token mechanism for victims launched (the pool started with $3.8M of remaining assets). |
| July 1, 2026 | The official rebrand: Drift Protocol becomes Velocity. The team's wording — "a cleaner architecture, a stronger security foundation". |
| July 14, 2026 | The closed beta launched for selected partners and traders (whitelist). |
| August 2026 | No public launch announced; documentation is being actively updated, and the post-fork OtterSec review is complete at the code level (the final report is being prepared for publication). |
A detailed technical breakdown of the incident is available in the Drift Protocol archive review.
Three liquidity sources: how trades execute
Velocity's hybrid execution model is inherited from Drift v2 and refined. Every market order passes through a three-mechanism cascade:
- JIT auctions (Just-in-Time): a market order first enters a short Dutch auction — in fast-fill mode (DLOB server v3) the auction starts inside the spread and lasts about 2000 milliseconds. Market makers compete for the right to fill the order at or better than the auction price, delivering execution with minimal slippage.
- The virtual AMM (vAMM): if the auction did not fill the order, the built-in designated market maker steps in — a constant-product (x·y=k) formula with an adaptive, inventory-driven spread. The vAMM bootstraps liquidity for new markets without external makers and relies on Pyth and Pyth Lazer oracles.
- The DLOB (Decentralized Orderbook): limit orders live on-chain, while a network of independent keeper bots sorts them into an off-chain book (prioritizing the oldest and largest orders) and executes them when trigger conditions are met. Keepers earn a share of the taker fee for their work.
Velocity has no spot order book: spot markets serve only collateral and lending, and token exchange runs through direct swaps (including leveraged swaps up to 5x via the Jupiter and Titan aggregators). Perp leverage is set by per-market caps — for example, SOL-PERP's ceiling is 20x at 5% initial margin; Drift's High Leverage Mode was removed entirely.
The insurance fund: 100% owned by stakers
Velocity's insurance model is radically more transparent than Drift's legacy. Protocol-owned fund shares and rebalancing instructions were removed: every dollar settling into the fund belongs to stakers and is distributed through share-price appreciation. Any user can stake an asset into a per-market fund and earn a share of trading, liquidation and lending fees, taking on the first-loss coverage risk of bankruptcies.
Coverage depends on the market's contract tier: tier A, B and C markets have decreasing caps on draws from the quote asset's shared fund, while Speculative, Highly Speculative and Isolated tier markets get zero insurance access — their losses are covered by the market's own fee pool and only then by the socialized-loss mechanism. The riskiest part of the perimeter is deliberately cut off from the fund protecting the conservative markets.
The perpetual bankruptcy waterfall: the estate's own claims → the market's unsettled insurance fees → the external insurance fund (within the tier cap) → the AMM fee-provision clawback → socialized losses pro-rata across the market's open positions.
Borrow & Lend and the Amplify product
Beyond perps, Velocity operates as a money-market protocol: deposits earn lenders an auto-compounding yield, and loans are issued over-collateralized at a variable rate. Collateral is shared across the whole cross-margin account: deposits in lending markets simultaneously back perpetual positions.
Amplify is a built-in recursive-borrowing (looping) strategy: the user deposits a yield-bearing asset as collateral, the protocol automatically borrows the paired asset, converts it back into the collateral asset and repeats the cycle up to the chosen leverage level, amplifying exposure to the yield. Velocity charges no fee for the product itself — only a third-party swap fee applies.
Fees and the revenue-distribution redesign
Taker fees are tiered by trailing 30-day trading volume; makers earn a rebate at every tier:
| Tier | 30-day volume | Taker BTC/ETH/SOL | Taker other markets | Maker |
|---|---|---|---|---|
| Regular User | < $5M | 0.040% | 0.055% | −0.0025% (rebate) |
| VIP 1 | $5–80M | 0.030% | 0.045% | −0.0025% (rebate) |
| VIP 2 | > $80M | 0.020% | 0.035% | −0.0025% (rebate) |
The difference between the columns is a per-market surcharge of 1.5 basis points for markets outside BTC/ETH/SOL. The referral system gives invited traders a 5% taker-fee discount and referrers 10–20% of the fees their referees pay. Governance-token staking discounts no longer exist: Velocity has no native token at all.
The revenue redesign splits every collected taker fill three ways: the vAMM provision, the insurance fund and the directly withdrawable protocol_fee_pool (withdrawals are locked to a fixed recipient and require the FeeWithdraw hot key). Protocol revenue no longer mixes with insurance-fund reserves.
What changed compared to Drift v2
| Category | Changes |
|---|---|
| Removed | The spot DLOB and external fulfillment providers (Serum, Phoenix, OpenBook); the Fuel loyalty program; vAMM LP shares; protected maker mode; High Leverage Mode; prediction markets; Switchboard oracles; governance-token staking fee discounts; protocol-owned insurance-fund shares; the durable-nonce mechanism — the April attack vector. |
| Added | The VLP module (a vAMM hedging pool); isolated perp positions (switched off on mainnet pending the audit); builder codes for interface monetization; a per-user equity floor; tiered cold/warm/hot/pause admin keys; fast-fill auctions; the three-way fee split; a 100% staker-owned insurance fund. |

Frequently Asked Questions
Is Velocity the same Drift Protocol or a new protocol?
Velocity is the rebrand of Drift Protocol, announced on July 1, 2026 after the April 1 hack. Technically it is a new deployment: the program was forked from the Drift v2 codebase (fork point 0ae3e3b1d) but runs under a new program ID, with no on-chain state carry-over and a reduced feature set. Old accounts and balances did not migrate to Velocity.
Can I trade on Velocity right now?
The platform has been in a closed beta since July 14, 2026: access is granted by whitelist to selected partners and traders. No public launch date has been announced. Connect a wallet and deposit funds only after confirming your access and verifying the domain.
Why does Velocity use USDT instead of USDC?
The switch to USDT is a condition of the ~$127.5 million Tether credit line granted to support the protocol's recovery and relaunch. USDT is the base collateral and settlement asset of all Velocity perpetual markets, whereas Drift ran on USDC.
What happened to the funds of affected Drift users?
A recovery-token mechanism is in place: every affected wallet received tokens at $1 per $1 of verified loss. Redemption unlocks when the recovery pool crosses $5 million; the pool is refilled from quarterly exchange revenue, the Tether commitment and up to $20 million from partners. Early redemption pays a pro-rata share of the pool and waives the remaining claim.
