# Bridging NFTs across layers ## Intro NFTs built on L2 can't be bridged to L1, which creates NFT silos. This document creates a way to easily transfer NFTs across layers and reduce the gas requirements by minting the NFTs on Layer 2. This lets the user decide when they would like to withdraw their NFTs to Layer 1. ## How it works The Owner will provision the L1\_NFT\_Collection with the deployed L2\_NFT\_Collection, specifying: * Address of the L2\_NFT\_Collection * Chain ID of the L2\_NFT\_Collection * Location of the NFT, mapping of the Chain ID by the NFT ID * Range of Allocated NFTs, e.g. #1-100, 60-61, etc. ### The document contains: * Claiming the NFT on L2 * Withdrawing an NFT * (Re)depositing the NFT on L2 * Diagrams of how it works Source: ## Further reading Cross-rollup NFT wrapper and migration ideas --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
