# Token Information
Octoblock's OCTO token serves as the primary governance mechanism for the protocol. The token tax is designed to address MEV sandwich bots and ensure a consistent revenue stream for the nautilus trove. To achieve this, OCTO token imposes a 2% tax on purchases and a 2% tax on sales, resulting in a total round trip cost of 4%.
**Taxation and Trading**
When trading OCTO token on a decentralized exchange (DEX), it is important to factor in the taxation by adding additional slippage to your trade. However, it is worth noting that prior to its launch on centralized exchanges (CEX), contributors will eliminate the tax function for tokens traded on CEX.
**Considerations for CEX Traded Tokens**
It is essential to consider that tokens traded on CEX without the taxation mechanism will not qualify for Nautilus Trove airdrop rewards. Therefore, users should carefully weigh the implications of trading OCTO tokens on CEX in relation to the potential loss of airdrop rewards.
