# Detailed Cross-chain NFT Mint, Lock, and Unlock Flow

* **Mint and Lock NFT:**
  * Mint and lock an Unlimited NFT Pass by paying a DAO donation during contract creation, timeout updates, or challenge period cancellations.
* **Benefits of Locked NFT:**
  * Skip regular DAO donations for contract creation and timeout updates on all supported chains.
* **Ethereum Automatic NFT Minting:**
  * When creating a contract or updating a timeout on Ethereum without owning an NFT, the NFT can automatically mint and lock if you select that option.
* **Cross-chain NFT Minting via Ethereum:**
  * For contract creation or timeout updates on other chains without owning an NFT:
    1. Switch to Ethereum to mint and lock the NFT, automatically propagating the lock data to other chains via deBridge.
    2. After receiving bridge confirmations, switch back to the target chain and confirm the transaction.
  * Once confirmed, future contract creations and timeout updates on that chain become free for existing and new contracts.
* **Cross-chain NFT Unlock via Ethereum:**
  * The locked NFT has a 5-month lock period on each chain, starting from the moment of locking.
  * Each contract timeout update or new contract creation automatically extends the NFT lock by an additional 5 months if the previous lock period has expired.
  * To unlock the NFT after the lock period ends:
    1. Send an unlock transaction on the target chain. This transaction automatically sends a cross-chain message to Ethereum via deBridge.
    2. Wait for bridge confirmations, then switch to Ethereum and confirm the unlock transaction.
* **NFT Unlock on Ethereum:**
  * To unlock the NFT on Ethereum, it must first be unlocked on all other chains.
  * After unlocking on all other chains and once the Ethereum lock period expires, send an unlock transaction on Ethereum. The NFT will then be withdrawn directly to your address.
* **Multiple NFT Mint on Ethereum:**
  * DAO multisig can set an NFT total supply threshold, after which it becomes possible to mint NFTs without locking to multiple recipients.
  * Useful for gifting NFTs or obtaining better tiers and IDs for your own or friends' future contracts.
  * To mint, send a transaction including recipient addresses and NFT amounts, along with the DAO donation.
  * Initially, this threshold is set to 500.
