Method Comparison: Bonding Curve vs. Token-2022
There are two primary technical methods to implement high slippage fees. The choice impacts flexibility, permanence, and compatibility.
1. Bonding Curve Slippage (Launch Phase)
- How it works: The fee percentage is hardcoded into the token's initial bonding curve on the launchpad. This is the standard method for new tokens on platforms like Spawned or pump.fun.
- Fee Example: Set at 0.30% per trade.
- Pros: Simple to set up at launch. Immediately generates revenue from the first trade.
- Cons: Difficult or impossible to modify after launch. Tied to the initial launch platform's curve.
2. Token-2022 Transfer Fee (Post-Launch/Graduation)
- How it works: Uses Solana's Token-2022 program, specifically the 'transfer fee' extension. This allows you to attach a fee to token transfers (which includes trades).
- Fee Example: Can be set up to 1% post-graduation, as used by Spawned for perpetual funding.
- Pros: Can be implemented after launch. Offers more granular control (e.g., setting a maximum fee). Future-proof and chain-native.
- Cons: Requires migrating to or minting with the Token-2022 program. Some wallets/DEXs may have slower adoption.
For most creators, starting with a bonding curve fee (like the 0.30% on Spawned) and later planning for a Token-2022 upgrade offers a balanced path.
