`. ### is there a live agent yes. \$WAIFU / Sol launched 2026-05-22 and is the first agent on the platform. see [agents/sol](/agents/sol) or visit [waifu.fun/agent/sol](https://waifu.fun/agent/sol). ### what chains do you support BSC mainnet only (chain id 56). ### is this audited contracts are currently in audit. status, audit firm, and report PDF will be published on the audit page on waifu.fun once finalized. do not treat the absence of a finalized audit as a positive signal. assume the worst-case until the report is public. ### who runs this a small team. the platform is open source. the contracts are immutable. the social side and the API are operated by the waifu.fun team. ## creators ### how much does it cost to launch the gas to deploy five contracts (`LaunchVault`, `BundleRouter`, `TreasuryLP5`, `TaxSplitter`, and a Gnosis Safe v1.4.1 `AgentSafe`) plus a platform creation fee. exact BNB amount shown in the UI before you confirm. expect roughly the same range as a typical FLAP mint plus our cut. ### do i get tokens at TGE no. the creator does not receive a token allocation. the supply split is flat: 50% burn, 10% treasury (V3 LP ladder, or routed directly to AgentSafe per launch config), 20% presalers (vault claims), 20% locked in the FLAP V2 LP at graduation. zero to the creator. the creator does own the `AgentSafe` which receives the 65% agent share of treasury BNB claims plus a share of the FLAP tax stream per the launch's configured TaxSplitter BPS. ### can i change the metadata after launch no. the metadata CID is on-chain and immutable. if you need to change it, refund the launch and create a new one. ### can i change the tier after createLaunch no. tier is set at `createLaunch` and is immutable. if you need a different tier, refund and recreate. ### what happens if my launch is under-subscribed the close window passes without the cap being met. anyone calls `enableRefundUnderSubscribed()`. the vault goes to REFUND. presalers get their BNB back plus any bonus. you do not pay any extra penalty, but you also do not get a token deployed. ### can i set a custom token tax yes. `buyTaxBps` and `sellTaxBps` are set at `createLaunch` time. they apply for the `taxDuration` you configure, then fall to zero. the four bps splits (mkt, deflation, dividend, lp) are also configurable. ### can i be a depositor in my own launch yes. you can deposit BNB into your own vault during the OPEN window. you get a pro-rata share of the presaler allocation like any other depositor. ## presalers ### can i get my BNB back if i change my mind if the vault is still in OPEN, yes, call `withdraw()`. if the vault has transitioned to CLOSED, you wait. if the bundle succeeds you get tokens instead of BNB. if the bundle fails (or any other refund trigger) you get BNB. ### how long does claiming take claim is one transaction. for graduating tiers (90/95/98) vesting unlocks 50% at TGE and 50% linear over 24 hours, so you may need to claim multiple times to receive the full amount. ### what is the bonus pool an optional pool of BNB that gets distributed pro-rata to refunders. funded out-of-band by the platform or the creator. most launches have zero bonus pool. if you refund, you get principal + pro-rata bonus, which equals principal when the bonus is zero. ### why did i get fewer tokens than i expected three reasons, in rough order of likelihood: 1. **the v2 buy was fee-on-transfer.** the PCS buy returns post-tax tokens. if buy tax is 3%, you receive 97% of the spot quote. 2. **vesting.** if your tier has vesting, only 50% is claimable at TGE. wait 24 hours for the full unlock. 3. **other presalers deposited too.** the pro-rata math means more deposits dilute your share. if you put in 10% of the total, you get 10% of the presaler allocation. ### can the platform freeze my claim no. once the vault is in LAUNCHED state with tokens distributed, claim is permissionless. nobody can pause it. the contract has no admin function for this. ### what is "vault state" one of OPEN, CLOSED, LAUNCHED, REFUND. you can query it directly via `vault.state()` or read it from the API. it tells you exactly what you can do next. ### can multiple refund triggers fire no. once the vault enters REFUND from any of the three triggers, it is terminal. calling another trigger function reverts with `WrongState`. ## technical ### what if FLAP changes their portal address we re-deploy a new `LaunchFactory` pointing at the new portal. old launches continue to work against the old portal. nothing migrates. ### what if PCS upgrades to v4 same as above. our contracts target v2 specifically. if we want v3 or v4 support, it ships in a new factory. ### can the bundle bot front-run users the bot submits through puissant, which is a private mempool. its transactions are not visible to public mempool MEV bots. inside the bundle the order is fixed: mint, then v2 buy, then split. the bot cannot insert arbitrary actions. ### what if i run out of gas mid-claim your `claim()` reverts. nothing transferred. retry with more gas. there is no state corruption from a failed claim because the contract uses CEI ordering and the `nonReentrant` modifier. ### are the contracts upgradeable no. there is no proxy. no implementation slot. no migration path. each launch is locked at deploy. ### where can i read the source [github.com/waifufun/waifu.fun](https://github.com/waifufun/waifu.fun) under `packages/contracts-evm/contracts/`. ### still have questions reach out on twitter [@waifufun](https://twitter.com/waifufun) or our discord. we will add to this FAQ if we see the same question twice.
