### Official Update: Pump.fun Launches "Cashback Coins" (Feb 17) Per official sources, Pump.fun rolled out its new "Cashback Coins" on February 17. Key rules for the token type: - **Pre-issuance choice mandatory**: Token issuers must pick one option *before* launching the token: 1. Reward traders with cashback, or 2. Cover the issuer’s own fees. - **Cashback mechanics**: Cashback tokens refund *all* issuer fees to traders. Once issued, the chosen option is **permanently locked in**. - **Difference from Creator Fee Tokens**: Cashback Coins cannot undergo a CTO and will permanently reward traders and holders. This format aligns with U.S. English brevity, clear bullet-pointed details, and natural phrasing (e.g., "rolled out" instead of "announced the launch of," "mandatory" for emphasis, "locked in" for clarity).
