Avantis is the "biological son" of the Base ecosystem, invested by Pantera & Founders Fund, with an average daily trading volume of over $100 million, and is the leading Perp DEX of Base. It pioneered the zero-fee perpetual model, with 0 fees and 0 funding rates for opening positions, and only charging 2.5% for profit orders, which greatly reduces friction. The mechanism adopts the vAMM model to support zero slippage for large transactions, and has a loss rebate mechanism, which can return up to 20% of the loss when opening a position against the trend, and at the same time introduces an XP points system, which may be associated with airdrops in the future. In terms of LP design, it supports active risk and return adjustment, combining layering and locking, with returns up to 4 times and 60% of the protocol's revenue. With the differentiated advantages of zero fee + RWA, @avantisfi is expected to become a bridge connecting TradFi and DeFi, opening up a new landscape of on-chain derivatives.
