Most perp volume lives on Hyperliquid, Arbitrum, and Solana — so if your assets are on Base, bridging out just to trade is friction. Avantis is the Base-native answer, and it's become the largest derivatives DEX on Base with over $18B in cumulative volume and 38,500+ traders. It's also one of the few on-chain venues offering real-world-asset perps — forex, commodities, and equities — alongside crypto. This is a deep, independent review of how it works for both traders and LPs, the unusual fee model, and the real risks.
What is Avantis?
Avantis is a perpetuals DEX on Base offering leveraged crypto, forex, commodity, and equity markets, with liquidity from a single unified USDC vault (avUSDC) — the largest derivatives venue native to Base. Last verified: 2026-06-14.
There are two sides to it. Traders get leveraged perps on Base without bridging — up to 500x on select crypto pairs and up to 25x on major equities — including non-crypto markets like FX and metals that most perp DEXs don't offer. LPs provide the USDC that backs those trades through the avUSDC vault and earn from fees and net trader losses. By DefiLlama, vault TVL stands around $23M, and the AVNT token's market cap is roughly $31M.
How Avantis works
Trading: leverage on crypto and real-world assets
Open leveraged longs/shorts collateralised in USDC on Base. The headline is the 500x ceiling on select crypto, but the more interesting differentiator is breadth: Avantis lists forex, commodities, and equities as perps, so you can take leveraged on-chain exposure to markets that normally require a brokerage. That RWA breadth is rare among perp DEXs and a real reason traders use it.
The avUSDC vault: how LPs become the house
This is the heart of Avantis, and worth understanding before depositing. LPs deposit USDC and receive avUSDC, an ERC-4626 yield-bearing token representing their share. The vault is the counterparty to every trade:
- It earns 100% of trading fees (excluding liquidation fees).
- It collects net trader losses and pays net trader profits — so LP returns track the aggregate PnL of traders.
The buffer mechanism softens the ride: when traders lose, those funds top up a buffer; when traders profit, payouts come from the buffer first, and the vault's principal is only drawn down if the buffer is depleted. It doesn't remove the core risk — that LPs lose when traders collectively win — but it absorbs ordinary volatility before touching deposits. As of October 2025, this is a single pool; the earlier senior/junior tranche system was merged into one avUSDC vault.
The fee model: pay on profit, not on entry
Avantis's economics are deliberately trader-friendly and unusual:
- Zero trading fees on majors (BTC, ETH, SOL).
- Fees charged on profit, not at open/close — you're not nicked just for entering.
- Loss rebates up to 20% for traders who take the side that balances open interest, lowering the effective cost of being the contrarian/less-crowded side.
The catch: costs still exist — they surface in spreads, funding, and the profit-fee model rather than a flat per-trade fee. Read how a specific market prices before you size up.
The AVNT token
AVNT is Avantis's native ERC-20 on Base, fixed supply of 1 billion. It's used for governance, staking (protocol rewards and fee discounts), and loyalty/XP boosts. As a governance-and-incentives token, its value tracks protocol usage and emissions — treat any staking yield as variable and incentive-driven.
Avantis vs the major perp DEXs
| Avantis | Hyperliquid | GMX | |
|---|---|---|---|
| Chain | Base | Hyperliquid L1 | Arbitrum / Avalanche |
| Engine | Pooled (avUSDC vault) | On-chain order book | Pooled (GLP-style) |
| Markets | Crypto + FX + commodities + equities | Crypto perps | Crypto perps |
| Max leverage | Up to 500x | High | Up to ~100x |
| Liquidity / depth | Smaller, growing | Deepest | Deep, established |
| Edge | Base-native + RWA markets | Liquidity, speed | Track record |
The honest read: for raw depth and spreads, Hyperliquid wins; for a long track record on the pooled model, GMX. Avantis's edges are being Base-native, its RWA market breadth, and a trader-friendly fee model — at the cost of being smaller and newer.
Who it's for / who should skip it
- Good for: Base users who want on-chain perps without bridging, traders who want FX/commodity/equity exposure on-chain, and LPs wanting counterparty-side vault yield with eyes open.
- Skip if: you want the deepest books and tightest spreads (Hyperliquid), or you can't stomach LP drawdowns when traders collectively win.
The risks (read before you deposit or trade)
- LP returns track trader PnL — they can be negative in trader-favourable stretches. The buffer cushions ordinary swings but doesn't remove the core risk.
- Leverage risk for traders. 500x means a tiny adverse move liquidates you; this is the highest-risk way to use the platform.
- Smart-contract & oracle risk. Funds sit in contracts; mispriced feeds can cause bad liquidations or vault losses.
- Smaller & newer than the majors — verify current audits and live liquidity, and size accordingly.
How to get started
- Get USDC onto Base and connect a self-custody wallet at Avantis. See our best crypto bridges guide if you need to bridge in.
- Traders: start with low leverage, isolated risk, and a stop-loss; remember you pay fees on profit, and that balancing open interest can earn a rebate.
- LPs: deposit into the avUSDC vault, treat it as real risk capital, and size small first — returns track trader PnL.
- Monitor the buffer, funding, and your position/vault health.

Final verdict
Avantis is the most credible Base-native perp venue, and its unified avUSDC vault is a genuinely interesting way to take counterparty exposure — with a buffer that softens volatility and a trader-friendly, pay-on-profit fee model. Its real differentiators are Base-native access and real-world-asset markets (FX, commodities, equities) that most perp DEXs simply don't offer. The caveats are real: it's smaller and newer than Hyperliquid and GMX, 500x leverage is a fast way to get liquidated, and LP returns depend on trader PnL — so trade with low leverage and treat the vault as risk capital, not a savings account.

Frequently asked questions
What is Avantis?
Avantis is a decentralized perpetuals exchange on Base offering leveraged trading on crypto, forex, commodities, and equities — up to 500x on select crypto pairs and up to 25x on major equities. Liquidity comes from a single unified USDC vault (avUSDC, an ERC-4626 token) where LPs take the other side of trades. With $18B+ in cumulative volume it positions itself as the largest derivatives venue native to Base, and one of the few offering real-world-asset (FX, commodity, equity) perps on-chain.
How does the avUSDC LP vault work?
LPs deposit USDC and receive avUSDC, an ERC-4626 yield-bearing token representing their pool share. The vault is the counterparty to traders, so it earns 100% of trading fees (excluding liquidation fees) plus net trader losses — and bears net trader profits. A buffer mechanism softens this: trader losses top up a buffer, trader profits are paid from the buffer first, and the vault's principal is only drawn down if the buffer is depleted. As of October 2025 it's a single pool; the earlier senior/junior tranches were merged into avUSDC.
What's the fee structure — is it really zero fees?
Avantis charges zero trading fees on major assets like BTC, ETH, and SOL, and notably you pay fees on profit rather than at open/close. It also offers loss rebates of up to 20% to traders who take the side that helps balance open interest. The trade-off is that costs surface in the spread, funding, and the profit-fee model rather than a flat per-trade fee — so read how a specific market prices before sizing up.
What is the AVNT token?
AVNT is Avantis's native ERC-20 on Base, with a fixed total supply of 1 billion. It's used for governance, staking to earn protocol rewards and fee discounts, and loyalty/XP boosts. As a governance-and-incentives token, its value tracks protocol usage and emissions — treat any staking yield as variable and incentive-driven, not a fixed return.
Is Avantis safe?
It's DeFi perps — inherently high-risk. Smart-contract, oracle (price-feed), and counterparty (LP) risks all apply, and Avantis is newer and smaller than Hyperliquid or GMX. For LPs specifically, returns track net trader PnL and can be negative when traders win, even with the buffer. Check current audits, use low leverage as a trader, and treat the vault as risk capital, not savings.
How does Avantis compare to Hyperliquid or GMX?
Hyperliquid has the deepest order-book liquidity and tightest spreads; GMX pioneered the pooled-liquidity perp model with a long track record. Avantis's edges are being Base-native (no bridging if your stack is on Base), offering real-world-asset markets (FX, commodities, equities) most perp DEXs lack, and a trader-friendly fee model. Its disadvantages are smaller size, newer code, and LP returns that depend on trader PnL.
