# 5.1 价值捕获机制

XUnit 的经济模型基于 协议原生价值流 而非代币通胀，具体包括：

1. 协议手续费（Protocol Fees）\
   \
   ৹  用户在 NFT 铸造、F-NFT 分割、跨链转移、流动性操作 等环节产生的费用将按比例收取；\
   \
   ৹  协议费可分配到 生态基金池，用于技术升级、生态补贴与安全审计。\ <br>
2. 资产映射保证金（Asset Collateralization）\
   \
   ৹  项目方接入 XUnit 时需缴纳一定形式的保证金（例如稳定币或 OKB），以确保真实资产映射的责任与合规性；\
   \
   ৹  保证金设计提高了接入门槛，降低劣质资产项目的风险。\ <br>
3. Genesis NFT 稀缺性\
   \
   ৹  Genesis NFT 本身即是早期用户的凭证与参与权益载体；\
   \
   ৹  Genesis NFT 可解锁：空投、未来白名单、收益分配权利，形成天然的价值沉淀。<br>
