Vest Markets Review — Live Volume, OI & Fees

Vest Markets Review 2026

An AMM that quotes you, not a book

Vest Markets is built on a premise most perp DEXes reject: no order book at all. Every trade executes against an internal AMM whose quotes come from zkRisk, a pricing engine built around entropic value-at-risk (EVaR). You take the protocol's price or you do not trade — there are no resting limit orders and no maker side. Vest is explicit about this; anyone describing it as an order-book venue has not read the docs.

The project has been live on DefiLlama since March 2024 under its old name, Vest Exchange, and rebranded to Vest Markets around September 2025. Settlement happens on Base, deposits arrive in USDC from multiple chains, and accounts are cross-margin only across all 155 markets — crypto, US equities, and FX in one bucket. Leverage runs to 50x and there is no KYC.

Audited, then stress-tested the hard way

Vest's contracts carry an OtterSec audit, which puts it ahead of the many young venues shipping unaudited. But 2026 demonstrated where the real risk lives: not in the contracts, in the pricing model. An audit checks that code does what it claims; it does not check that EVaR quotes track reality under stress. The two incidents were pricing failures, not exploits — no funds were stolen, and the team's remediation was fast both times. Our security score weighs the audit up and the operational record down.

What trading costs, by session

Crypto pairs cost a flat 0.01% per fill, on both sides of every trade — a maker/taker split makes no sense on a venue with no makers. Non-crypto markets price by the clock instead: the effective rate on US equities is 0% while their home market is open, stepping up toward 0.05% overnight and toward 0.10% on weekends, while FX pairs run at an effective 0% throughout the trading week.

Read that pricing model for what it is: Vest charges you for liquidity when the real-world hedge is expensive, and nothing when it is cheap. Traders who work US market hours get equity perps at costs no order-book venue matches. Weekend position traders pay the venue's highest rates precisely when they are most likely to want in or out.

The April rollback and the June ES bug, on the record

Two incidents in 2026 belong in any honest review, and most coverage omits both. On April 15, 2026, a mispricing event triggered erroneous liquidations that hit roughly one in ten accounts, and Vest responded by rolling back the entire platform's state. On June 8, 2026, a second pricing bug affected the ES market; affected traders were compensated.

The rollback deserves two readings. The generous one: users were made whole, which is more than traders on several failed venues ever got. The sober one: a venue that can roll back state is a venue where your PnL is provisional until the operator says otherwise, and a pricing engine that misfires twice in three months is not yet proven. When one model is both your counterparty and your oracle, model risk is the product. Size accordingly.

Backers, points, and the referral fine print

The $5 million seed round from March 2025 is unusually strong for the size: Jane Street, Selini Capital, Amber Group, and QCP. Market makers backing a venue whose whole thesis is replacing market makers is genuinely funny, and probably informative.

A weekly points program runs with no token announced. The referral scheme has a catch worth knowing before you use anyone's link: the referrer earns points from your activity, and you receive no fee discount at all. Check current terms on our deals page — as of July 2026 a referral costs you nothing, but it also gets you nothing.

By the numbers, Vest reported open interest near $75 million in early July 2026, with cumulative volume around $12 billion since 2024 and daily turnover that swings from single-digit millions to tens of millions depending on the week. Mid-table on our rankings, and small enough that the session-pricing edge is the main draw.

Where Vest fits in July 2026

Best case: you trade US equities or FX during their market hours, in moderate size, and want crypto exposure in the same cross-margined account — the session pricing is unbeatable for exactly that. Wrong venue if you need limit orders, trade weekends, or cannot tolerate operator-discretion risk after the April rollback. Cheap has a reason here; make sure you are being paid for it.
