Avantis is the 'golden child' of the Base ecosystem, backed by investments from Pantera & Founders Fund. With a daily trading volume exceeding $100 million, it’s the leading Perp DEX on Base. They pioneered a zero-fee perpetual model: 0 fees for opening positions, 0 funding rates, and only a 2.5% charge on profitable trades, significantly reducing friction. The mechanism uses a vAMM model to support large trades with zero slippage and features a loss rebate system—offering up to 20% loss rebates for countertrend positions. Additionally, they’ve introduced an XP points system, which may be tied to future airdrops. For LP design, it allows active adjustment of risk and returns, combining tiering and lock-up mechanisms. Returns can go as high as 4x, with LPs sharing 60% of the protocol’s revenue. With its unique zero-fee + RWA advantages, @avantisfi is poised to become the bridge connecting TradFi and DeFi, opening a new chapter for on-chain derivatives.
