# Limits and validation

> Current launch defaults, contract hard caps, form limits, allocation rules, vesting rules, fee limits, and quote requirements.

The interface checks launch inputs before the wallet asks for a signature. The contracts enforce the hard caps again onchain.

## Current defaults

| Setting            |                             Current value |
| ------------------ | ----------------------------------------: |
| Supply             |          1 billion (1,000,000,000) tokens |
| Liquidity ranges   |                                         1 |
| Base swap fee      |                                        1% |
| Starting total fee |                                       99% |
| Anti-snipe period  |                                16 seconds |
| Base-fee split     | 50% creator / 30% platform / 20% referrer |

## Contract hard caps

| Constraint                       |                        Hard limit |
| -------------------------------- | --------------------------------: |
| Token supply                     |    1 million to 1 trillion tokens |
| Immediate plus vested recipients |                         128 total |
| Vested beneficiaries             |                                64 |
| Vesting steps per beneficiary    |                                24 |
| Vesting steps across one launch  |                               128 |
| First vesting unlock             |       At least 1 day after launch |
| Liquidity ranges                 |                           1 to 10 |
| Base swap fee                    |                       At most 10% |
| Starting total fee               |                       At most 99% |
| Profile authority choice         | Fixed profile or editable profile |

The supply caps assume the launch token's standard 18 decimals.

Creator-profile changes use a wallet signature and affect the public o1 profile only. They do not change token permissions, balances, or liquidity.

## Allocation and vesting rules

* every amount must be greater than zero;
* a recipient can appear only once across immediate and vested allocations;
* allocations must leave at least some supply for the market;
* vesting dates must strictly increase;
* each step must release a positive percentage;
* all step percentages must add up to exactly 100%;
* the first unlock must be at least one day after launch;
* each step must release an additional token amount after rounding;
* locked tokens always pay the beneficiary recorded at launch.

## Fee and referral rules

* creator, platform, and referrer shares must add up to 100% of the base fee;
* the starting total fee cannot be lower than the normal base fee;
* the anti-snipe period must be longer than zero;
* the platform fee receiver must be a valid address;
* the trader, creator, platform fee receiver, empty address, and swap router or execution contract cannot receive referral credit for that trade;
* the unused referral share goes to the platform.

## Quote requirements

Only quote currencies registered by o1 governance can be selected. Quote tokens must behave like standard ERC-20 tokens. Transfer-tax, rebasing, and other non-standard balance behavior is not supported because it can break pool and fee accounting.

## Transaction checks

A launch stops when the selected quote is unavailable, the payment is wrong, the transaction has expired, current settings differ from the values the creator reviewed, recipients or vesting are invalid, or the pool cannot open with token-only liquidity.

Developers who need the exact encoded caps and field names can use [Functions and events](/launchpad/reference/events-functions) and the [machine-readable production snapshot](/launchpad/reference/production-deployments.json).
