This page explains what you pay and how the built-in market calculates prices. Always verify the live values in the Wemog interface and wallet prompt before you sign.

​
Launch tiers

Wemog supports six fixed collection sizes. The factory’s current default tiers are: The protocol can add or update tiers for future launchpads. Creating a launchpad snapshots its tier economics. Later tier changes do not alter that launchpad’s starting price, curve shape, or graduation target. You pay the launch fee when you create the launchpad. Network gas is separate. Activation has no separate launch fee, but you must pay for an optional creator-first purchase.

​
Trading fees

The factory’s current defaults for new launches are:
  • Buy and sell fee: 5% of the calculated market price.
  • NFT swap fee: 0.002 ETH per NFT.
  • Creator share: 25% of each trading or swap fee.
  • Protocol share: 75% of each trading or swap fee.
The contract copies these settings into a collection when its market contracts activate. Always use the live quote for that collection. Network gas is separate from displayed market and protocol fees.

​
Gacha randomness fee

Gacha buys and swaps include a live Chainlink VRF fee. This fee pays for the verifiable randomness request and appears separately in the trade ticket. A batch of up to 10 buys or up to 5 swaps uses one VRF request. The batch pays one randomness fee instead of one fee per NFT.

​
How bonding prices move

The market uses a collection-level bonding curve:
  • A buy removes one NFT from market inventory and moves the next price up.
  • A sell adds one NFT back to market inventory and moves the next price down.
  • A swap replaces one available ID with another. It does not change the sold count or curve price.
Artwork and rarity do not affect this price. Every available NFT at the same curve state has the same gross buy price. Every owned NFT accepted by the market has the same gross sell value.

​
Batch pricing

A batch does not cost quantity × current price.
  • During a batch buy, each item moves the curve before the contract prices the next item.
  • During a batch sell, each item moves the curve down before the contract prices the next item.
  • A batch swap charges the fixed swap fee once per pair.
Wemog requests the exact aggregate quote from the active market and shows it before submission.

​
Slippage protection

Prices can change between the time you receive a quote and the time your transaction executes. For buys, slippage sets a maximum payment. For sells, it sets a minimum received. If the onchain quote moves outside that limit, the transaction reverts instead of accepting the worse price. A reverted transaction can still cost gas.

​
Graduation

Graduation happens when the net sold count reaches the collection’s target. The current default tiers use a target equal to 51% of maximum supply. The counter is net of sells: buying increases it, while selling decreases it. When the target is reached, graduation occurs automatically and cannot be reversed. The Gacha pool inherits the curve’s state and liquidity. Its first market quote continues from the curve instead of starting over.
Defaults can change for future launchpads. The live collection quote and onchain configuration are authoritative.
