Excalibur is a Fantom-based AMM that offers fee mining, swap referrals, and customizable fees. It aims to achieve long-term efficiency and sustainability through advanced shareholding mechanisms, time vault staking, and project-owned liquidity. The swap fees allocation has been completely redesigned to provide better and more tailored rewards to all participants in the ecosystem. This will result in a fairer and more sustainable protocol that ensures its long-term value and efficiency. Excalibur also features a unique referral system for partners to expand the use of the DEX and create a new ecosystem. Each project acting as a referrer and facilitating user swaps on the DEX will automatically receive a share of the referred trading fees. Transaction fee mining is another key feature of Excalibur, where users receive the transaction fees in the form of the native token, EXC. Up to 100% of the trading fees can be claimed immediately. To incentivize long-term staking, Excalibur has implemented a time vault mechanism that allows users to lock their deposits for up to 30 days. The longer the lock, the higher the bonus rewards earned. Users can set up multiple simultaneous locks with different durations to implement suitable strategies. The second-layer token, $GRAIL, acts as shares of the DEX and can primarily be obtained through yield farming on EXC pairs. Holding $GRAIL in your wallet entitles you to continuous daily dividends from the platform's collected fees. The majority of the collected fees are redistributed through the dividends system or stored as project-owned liquidity governed by a DAO. A portion of the fees is allocated to user insurance through a SAFU fund, as well as to the team and treasury for further development of Excalibur.
