    Capital Aggregator Token: $CAT
    - The aggregator of aggregators. Granting holders exposure to a range of cross chain yield generating tokens.
    - Buy one token ($CAT) to earn yield generated from multiple other aggregator projects.

    Tokenomics:
    10% of each buy goes to existing holders (reflection).
    10% of each sell is divided into:
        4% Marketing Wallet: For marketing, growth and promotion of CAT.
        4% Treasury Wallet: Invests in multi-chain farming projects to redirect yield into buy backs of CAT.
        2% Auto-Adds Liquidity: Automatically adds liquidity to CAT.
