### Ethereum Worlds Vault The *Ethereum Worlds Vault* is a unique mechanic being introduced into the trading ecosystem. Each Vault will be filled with a selection of rare Collectible NFTs that can only initially be obtained via this mechanic. The Vault will operate on a global fixed supply of unlockable transactions in order to maintain fairness. This means that as each Vault is unlocked, it will continually reduce the number of remaining Vaults. Once a user has unlocked a Vault, they will be required to wait a fixed period of time until they're able to unlock another one. {% hint style="warning" %} **PLEASE READ:** The vault mechanic will only be available to holders in compliance with local regulations and guidelines set forth by the U.S. Securities and Exchange Commission (SEC). All holders must adhere to applicable laws and SEC regulations governing the above activities. {% endhint %} {% hint style="info" %} **NOTE:** More details will be shared as we get closer to release. {% endhint %}
