# Fees, anti-snipe, and referrals

> Free token creation, paired-asset swap fees, the 16-second anti-snipe period, referral links, attribution rules, and trade comments.

o1 Launchpad currently charges no token creation fee. Every swap pays a fee in the pool's paired asset, which becomes claimable by the creator, platform, and valid referrer.

## Creation fees

| Chain and route  | Paired assets          | Current creation fee |
| ---------------- | ---------------------- | -------------------: |
| Base crypto      | ETH or USDC            |                 Free |
| Robinhood crypto | ETH or USDG            |                 Free |
| Robinhood stocks | Supported Stock Tokens |                 Free |

The creator still pays the network gas required to confirm the launch transaction. No ETH, stablecoin, or Stock Token approval is needed for a creation fee on any available route under the current configuration.

## Normal swap fee

The normal swap fee is **1% of the paired-asset amount**. With a valid referrer, that 1% is divided as follows:

| Recipient | Share of the 1% fee | Equivalent share of the trade |
| --------- | ------------------: | ----------------------------: |
| Creator   |                 50% |                          0.5% |
| Platform  |                 30% |                          0.3% |
| Referrer  |                 20% |                          0.2% |

If a trade has no valid referrer, the unused 0.2% referral share goes to the platform. Fees are always denominated in the selected paired asset:

* an ETH market charges ETH;
* a USDC market charges USDC;
* a USDG market charges USDG;
* a stock-paired market charges its selected Stock Token.

For a stock-paired buy, the fee comes from the Stock Token paid. For a stock-paired sell, the fee comes from the Stock Token received.

## First 16 seconds

Trading remains open when the pool launches. The total fee starts at 99% and decreases linearly to the normal 1% fee over 16 seconds. This timestamp-based schedule makes immediate sniping intentionally uneconomic.

|    Time since launch | Approximate total fee |
| -------------------: | --------------------: |
|            At launch |                   99% |
|            4 seconds |                 74.5% |
|            8 seconds |                   50% |
|           12 seconds |                 25.5% |
| 16 seconds and later |                    1% |

The creator and referrer shares are calculated from the normal 1% fee. The temporary amount above 1% is the anti-snipe surcharge and goes to the platform.

<Note>
  o1 uses input-amount swaps: traders enter how much they want to spend or sell, and those swaps remain available throughout the 16-second period. Direct integrations that request an exact output are rejected until the fee reaches 1%.

## Get a referral link

o1 provides two types of referral links:

| Link            | Where to copy it                                                     | When it applies                                   |
| --------------- | -------------------------------------------------------------------- | ------------------------------------------------- |
| Global referral | Open your profile and select **Referral**                            | Used as your general referral across o1 Launchpad |
| Token referral  | Open a token page, connect your wallet, and select **Referral link** | Applies first to that token on that chain         |

The **Profile** link on a profile page is only a public profile link. It does not set referral attribution unless it also contains a referral parameter.

## Which referral is used

For each token, the interface checks referral attribution in this order:

1. a token-specific referral for that exact chain and token;
2. the connected wallet's previously saved global referral;
3. a global referral saved in the current browser.

If the first candidate is invalid, the interface tries the next valid candidate. Opening a token-specific referral link also becomes the global fallback when the visitor does not already have one. Once a wallet has saved a global referral, later global links do not replace it; a token-specific link can still take priority for its exact chain and token.

When a connected wallet first uses a browser-saved global referral, the interface may request a gasless signature to save that attribution to the wallet profile. This is not a token approval or an onchain transaction.

When the trader submits a swap, the interface includes the selected referral address with that trade. `LaunchHook` validates it again onchain before crediting the referrer's share. An invalid referral never blocks the swap: the hook ignores it and sends the unused referral share to the platform.

## Referral protections

A referral is ignored when it points to:

* the trader's connected wallet;
* the launch creator;
* the platform fee receiver;
* an empty or malformed address;
* the swap router or execution contract.

These checks prevent self-referral and protected-recipient referral. If no candidate is valid, the trade still works and the referral share goes to the platform.

## Trade comments

A trader may attach an optional comment of up to 32 UTF-8 bytes. The comment is included with the public onchain trade record, together with the direction, paired asset, referrer, and fee.

## Claiming fees

Creator, platform, and referral balances accumulate until claimed. Creators and referrers can open their connected Profile page and use **Fee claims**, where balances are grouped by ETH, stablecoin, or Stock Token. See [Claims](/launchpad/trading/claims) for the complete interface flow and [Functions and events](/launchpad/reference/events-functions) for direct contract integration.
