In August 2023, y00ts — a prominent Non-Fungible Token (NFT) project originally launched on Solana — announced its migration from Polygon to Ethereum. The team behind y00ts, DeLabs, also committed to returning a $3 million grant received from Polygon Labs, underscoring the project’s strategic shift toward greater blockchain flexibility.
But why would an established NFT project move across blockchains? The answer lies in the fragmented nature of today’s Web3 ecosystem. Most blockchain networks operate in isolation, each with unique consensus mechanisms, programming languages, and communities. As demand for broader utility and accessibility grows, projects like y00ts are recognizing the limitations of being confined to a single chain.
Cross-chain interoperability is emerging as a critical solution, enabling NFTs to transcend their native blockchains and unlock new levels of functionality. This article explores the challenges facing current NFT ecosystems, defines what cross-chain NFTs are, explains how they work, and highlights key use cases. We’ll also examine how next-generation protocols are paving the way for seamless multi-chain experiences.
Challenges Facing Today’s NFT Projects
At their core, NFTs are unique digital assets recorded on a blockchain. Unlike fungible tokens such as ETH or BTC, NFTs are indivisible and non-interchangeable. Each is governed by a smart contract deployed on a specific blockchain — and that’s where the limitation begins.
When an NFT is minted on Ethereum, it remains tied to Ethereum. It cannot be directly traded or used on Avalanche, Solana, or any other chain without complex workarounds. This siloed structure creates several systemic issues:
- Limited accessibility: Users must hold native tokens of a particular chain to interact with its NFTs. For newcomers, this means navigating multiple wallets, exchanges, and gas fees — a steep learning curve.
- Fragmented liquidity: With NFTs locked within individual ecosystems, marketplaces suffer from reduced trading volume and inefficient price discovery.
- Reduced utility: An NFT’s potential uses — such as serving as collateral in DeFi or unlocking in-game benefits — are restricted to one network.
These barriers hinder mainstream adoption and prevent NFTs from realizing their full value across Web3.

What Are Cross-Chain NFTs?
Cross-chain NFTs (also known as cross-domain NFTs) are digital assets designed to function across multiple blockchain networks. While the term “moving” an NFT is commonly used, technically speaking, the original token isn’t physically transferred.
Instead, the asset is either locked or burned on the source chain, and a corresponding version is minted or unlocked on the destination chain. This process preserves scarcity and ownership while enabling interoperability.
Key Benefits of Cross-Chain NFTs
- Enhanced Liquidity: By bridging ecosystems, NFTs can be utilized in DeFi protocols across chains — for example, using an Avalanche-based NFT as collateral on an Ethereum lending platform.
- Broader Audience Reach: Projects can attract users from various blockchains without forcing them to switch ecosystems.
- Greater Utility: NFTs gain expanded functionality — think staking on BNB Smart Chain, participating in governance on Polygon, or unlocking rewards in a Solana-based game.
These advantages make cross-chain NFTs a cornerstone of the next phase of Web3 evolution.
How Do Cross-Chain NFTs Work?
Enabling cross-chain functionality requires two foundational components:
- A Cross-Chain Messaging Protocol: This allows smart contracts on one blockchain to securely communicate with those on another. Without reliable message passing, trustless interoperability isn’t possible.
- Paired Smart Contracts: One contract resides on the source chain; another on the destination chain. These contracts coordinate actions like locking, burning, minting, and unlocking.
There are three primary methods for implementing cross-chain NFT transfers:
1. Lock and Mint
The user locks their NFT in a smart contract on the source chain. A replica is then minted on the destination chain. To reverse the process, the copy is burned, and the original is unlocked.
2. Lock and Unlock
The original NFT is locked on the source chain, and a previously minted equivalent is unlocked on the destination chain. Only one version can be active at a time.
3. Burn and Mint
The original NFT is destroyed (burned) on the source chain, triggering the creation of a new instance on the target chain. This ensures strict 1:1 scarcity but removes the original permanently unless reminted.
Each method balances security, efficiency, and user experience differently — developers choose based on their project’s needs.
Real-World Use Cases for Cross-Chain NFTs
Cross-Chain DeFi Integration
NFT holders can leverage their assets across decentralized finance platforms regardless of the underlying blockchain. Imagine pledging a Bored Ape Yacht Club NFT as collateral on an Arbitrum-based lending protocol — all without leaving your preferred network.
Art & Collectibles Without Borders
Artists benefit from wider exposure when their creations are accessible across marketplaces like OpenSea (Ethereum), Magic Eden (Solana), and Blur (multi-chain). Cross-chain NFTs eliminate platform lock-in and boost liquidity.
Interoperable Gaming Ecosystems
Gamers can carry avatars, weapons, or achievements from one game to another — even if each runs on a different blockchain. A sword earned in a Polygon-based RPG could be used in a Solana-powered battle arena.
Digital IP and Licensing
NFTs increasingly represent intellectual property rights. Cross-domain capabilities allow creators to license patents or copyrights across jurisdictions and platforms seamlessly — all verifiable on-chain.

Frequently Asked Questions (FAQ)
Q: Can you really move an NFT from one blockchain to another?
A: Not directly. The original token stays on its native chain. Instead, it’s locked or burned, and a corresponding token is created on the destination chain.
Q: Are cross-chain NFTs secure?
A: Security depends on the underlying interoperability protocol. Trusted solutions use verifiable message passing and audited smart contracts to minimize risk.
Q: Does using cross-chain NFTs cost more?
A: There may be additional gas fees for bridging transactions, but these are often offset by increased utility and access to larger markets.
Q: What happens if the bridge gets hacked?
A: Reputable cross-chain systems incorporate fail-safes, multi-signature validation, and decentralized validation layers to protect against exploits.
Q: Can metadata travel with the NFT?
A: Yes — though it requires careful handling. Off-chain metadata (like images or descriptions) must be stored in decentralized systems like IPFS to remain accessible across chains.
The Future: Automated Cross-Chain Interoperability
To fully unlock cross-chain potential, seamless automation is essential. Analog is developing a General Message Passing (GMP) protocol that enables developers to execute smart contract calls across chains securely and efficiently.
With GMP, an NFT hosted on Ethereum can trigger actions on Binance Smart Chain, Polygon, or Avalanche — all within a single transaction flow. This level of composability opens doors for:
- Unified DeFi dashboards managing assets across chains
- Dynamic NFTs that evolve based on activity in multiple ecosystems
- Cross-chain DAO governance using soulbound tokens
As Web3 matures, isolated blockchains will give way to an interconnected network of value and identity — powered by interoperable NFTs.

Final Thoughts
The movement toward cross-chain NFTs isn’t just a technical upgrade — it’s a paradigm shift. By breaking down silos between blockchains, we’re enabling true digital ownership that moves freely across platforms, applications, and economies.
Projects like y00ts are just the beginning. As infrastructure improves and user demand grows, cross-chain functionality will become standard — not optional.
For creators, collectors, and developers alike, now is the time to embrace interoperability and build the future of open digital ecosystems.
