Fees

Koal charges fees on the bonding curve and at graduation. Every fee is collected on-chain at the moment of the transaction and shown in the interface before you confirm. There are no subscription fees, no creation fees, and no fees for connecting a wallet.

Network gas costs and any fees charged by your wallet provider are separate from Koal fees and are paid directly to the relevant blockchain or third party.

While a token trades on its bonding curve, every buy and sell carries a protocol fee that scales down as the curve fills with ETH. Early buyers pay slightly more; late buyers pay almost nothing. The intent is to reward conviction and protect new launches from snipers.

The exact fee for any trade is computed by the KoalVault contract from the curve's real ETH reserve at the moment of execution. The interface displays the applicable rate before you confirm. Final fee charged is whatever the smart contract computes on-chain.

When a creator launches a token they may configure a creator fee. The creator fee is taken as a portion of the protocol fee — it is not an additional charge on top. The maximum creator share is 25% of the protocol fee. The remaining 75% (or more, if a smaller creator share is chosen) goes to Koal.

• Maximum creator share — 25% of the protocol fee (enforced on-chain by MAX_CREATOR_SHARE_BPS in KoalVault).
• Recipient wallets — up to 10 addresses per token, with custom percentage splits that must sum to 100%.
• Distribution — handled by the KoalVault contract on-chain at the time of each trade. Recipients claim accrued fees via a pull mechanism.
• Opt-out — creators who do not configure recipient wallets forfeit the creator share, which rolls into Koal's portion.
• Tax responsibility — creators are solely responsible for declaring and paying any taxes on fees received. Koal does not withhold or report.

How a creator splits fees between team members, contributors, or referrers is a matter between the creator and those parties. Koal records the split on-chain but does not police, advise on, or guarantee any of these arrangements.

When a token reaches graduation threshold (~$69K–$90K market cap depending on configuration), the bonding curve closes and liquidity is migrated to a decentralised exchange as a full-range LP position whose receipt is burned forever. A one-time graduation fee is taken from the migrating pool to fund deployment, ongoing development, and protocol buyback. The fee is currently set to 1% of the migrating amount and is capped on-chain at 5%.

The graduation fee is skimmed from both sides of the pool before it seeds the DEX:

• ETH side — 1% of the ETH being migrated is sent to KoalVault and split between operations and protocol buyback.
• Token side — 1% of the 200M tokens reserved for the DEX is burned by the factory before liquidity is seeded. Total supply of the token decreases by this amount permanently (at the 1% default, a 1,000,000,000 supply becomes 998,000,000 after graduation).

Skimming proportionally from both sides preserves the curve's final price ratio for the DEX pool's opening price. The fee is paid by the pool, not by any individual user, and the graduation event is publicly visible on-chain before, during, and after migration.

Because KoalOFT tokens are omnichain, moving a token between supported EVM chains involves a LayerZero message. The cost of that message has two components, neither of which is collected by Koal:

• Source chain gas — paid to the source blockchain for executing the send.
• LayerZero fee — paid to LayerZero DVNs and Executor for relaying and verifying the message on the destination chain.

Both costs are quoted in the interface before you sign. If a transfer fails after the message is sent, recovery is governed by LayerZero's protocol mechanics and is outside Koal's control.

The Koal portion of every trade fee — and of the ETH-side graduation fee — is split on-chain between two destinations:

• Buyback sink — the majority of Koal's share of trade fees is routed to a buyback address. Once the $KOAL token launches in a future phase, accumulated ETH at this address is intended to be used to buy back and burn $KOAL on the open market.
• Operations — the remainder funds ongoing development, infrastructure, audits, and liquidity needs of the protocol.

The exact split between buyback and operations is governed on-chain by KoalVault and is subject to owner-set parameters within hard-coded caps that ensure the buyback portion remains meaningful. The ETH-side graduation fee follows a similar split (currently weighted more evenly between the two sinks than the trade-fee split). Use of buyback funds prior to $KOAL launch, and any future change to either split, will be reflected on this page.

The following costs are not Koal fees and we do not control them:

• Network gas fees on Base, Arbitrum, or any other supported chain.
• Wallet provider fees (MetaMask, Rainbow, WalletConnect bridges).
• LayerZero relay and DVN fees on cross-chain transfers.
• Slippage on graduation or external DEX trades.

These appear in your wallet's transaction preview and may differ slightly from the estimate shown by the Platform due to network conditions.

Fees may be adjusted as the Platform evolves, new chains are added, or economic parameters are tuned. Material changes will be reflected on this page with an updated effective date. Continued use of the Platform after a change constitutes acceptance of the updated fees. The version of the fee that applies to any given trade is the version active in the smart contract at the time of execution.

Koal is the trading name of the platform operated by LensARstore. Fees described above are collected by Koal smart contracts deployed on public blockchains. For questions about a specific charge, see our Terms of Service or contact legal@koal.fun.
