The 70/30 Split: Is It Really Optimal?
The 70/30 liquidity-to-acquisition ratio is the most commonly cited default for token launches. But is it actually optimal? We ran the Token Launch Simulator at three splits (60/40, 70/30, and 80/20) with a fixed $25,000 budget and 1 billion token supply.
The Core Tradeoff
| Split | Liquidity (L) | Acquisition (P) | Supply Ownership | Price Appreciation | Final Market Cap |
|---|---|---|---|---|---|
| 60/40 | $15,000 | $10,000 | 40.00% | 177.78% | $41,667 |
| 70/30 | $17,500 | $7,500 | 30.00% | 104.08% | $35,714 |
| 80/20 | $20,000 | $5,000 | 20.00% | 56.25% | $31,250 |
The tradeoff is stark. Moving from 80/20 to 60/40 doubles your supply ownership (20% to 40%) and nearly triples your price appreciation (56% to 178%). But it comes at the cost of $5,000 less in initial liquidity.
The Surprise: Post-Buy Slippage Is Identical
Here’s what most guides don’t tell you. The slippage table after the founder buy is exactly the same across all three splits:
| Trade Size | 60/40 Impact | 70/30 Impact | 80/20 Impact |
|---|---|---|---|
| $1,000 | 4.00% | 4.00% | 4.00% |
| $5,000 | 20.00% | 20.00% | 20.00% |
| $10,000 | 40.00% | 40.00% | 40.00% |
Why? Because the founder buy adds base asset to the pool. After both the liquidity deposit and the acquisition buy, the total USD in the pool equals the total budget regardless of the split. At 60/40: $15,000 + $10,000 = $25,000. At 80/20: $20,000 + $5,000 = $25,000. The constant product formula produces the same post-buy pool state.
The split doesn’t affect trader slippage: it only affects:
- Founder ownership (higher with more acquisition)
- Price signal at launch (higher appreciation = higher starting market cap)
- The price the founder pays (more buying = worse average price per token)
So What’s the Right Split?
The answer depends on what you’re optimizing for:
- 60/40 if founder ownership and a strong price signal matter most. The 40% ownership and 178% appreciation create a narrative of founder conviction.
- 70/30 if you want a balanced position. 30% ownership is meaningful without appearing to dominate supply.
- 80/20 if you want the lowest-cost entry and the community to own more. 20% ownership signals a community-first approach.
Since post-buy slippage is identical, the “optimal” split is a governance and signaling decision, not a liquidity engineering one.
See the tradeoff for yourself: drag the liquidity slider in the Token Launch Simulator and watch ownership, price appreciation, and market cap change while the slippage table stays the same.
