# Coin tokenomics

With “Spend my fee share automatically” on, the creator’s share of the trading fees goes to a **vault** made for that launch, not to the creator wallet. The vault spends it in the shares you set at launch. The split is fixed at launch.

| Bucket | What the vault does with it |
| --- | --- |
| Burn | Buys your coin and burns it. |
| Buy and hold (treasury) | Buys your coin and sends it to your treasury wallet. |
| Add to liquidity | Buys your coin and adds it to the pool, locked for good. |
| Creator | Paid to your creator wallet, in the chain’s coin. |
| Community wallet | Paid to a community wallet, in the chain’s coin. |

- The shares add up to 100%. The form offers presets (Balanced, All burn, Liquidity, Community) or your own split.
- “A different split on each chain” sets each chain’s shares on their own. Otherwise every chain uses the same split.
- It works on every chain of the launch, Solana included. Solana takes its own treasury and community wallets.
- With tokenomics on, the fee receiver is not used, the fees cannot also be burned, and you cannot send your own chain’s launch yourself: the vault is the coin’s fee receiver.

## When the vault runs

- At most once every 15 minutes on each chain, at the market price. There is no reference price, and each buy’s price impact is capped at the pool’s own fee, so a large balance is spent over several runs.
- A bucket waits until it holds enough to be worth a run: 0.15 ETH on Ethereum, 0.0015 ETH on Base and Robinhood Chain, 0.008 BNB on BSC and 0.025 SOL on Solana.
- A run pays its own gas from what it spends, at most 10% of it on the EVM chains and 2% on Solana. On Ethereum, where gas is dear, buys wait until the pool is deep enough for that.
- On Solana the liquidity bucket also repays the rent of the coin’s liquidity position there, at most 0.015 SOL.

> **Note:** Setting the vaults up is part of the launch fee. When the creator and community shares together are above about 62% and the split also buys, those wallets can profit by trading around the vault’s own buys; the form warns about it.
