Supported Chains

Complete list of blockchain networks supported by NFT Backup.

Filebase NFT Backup supports 24+ blockchain networks across EVM and non-EVM ecosystems.

EVM-Compatible Chains

These chains use Ethereum-style wallet addresses (0x...) and are indexed via the OpenSea API.

Chain	Network
Ethereum	Mainnet
Polygon	Mainnet
Arbitrum	One
Optimism	Mainnet
Base	Mainnet
Avalanche	C-Chain
BNB Smart Chain	Mainnet
Immutable	X
Ronin	Mainnet
Blast	Mainnet
Sei	Mainnet
Shape	Mainnet
Unichain	Mainnet
Zora	Mainnet
Abstract	Mainnet
Ape Chain	Mainnet
B3	Mainnet
Bera Chain	Mainnet
Gunzilla	Mainnet
HyperEVM	Mainnet
Somnia	Mainnet
Soneium	Mainnet

EVM Wallet Address Format

EVM wallet addresses follow this format:

• Start with 0x

• Followed by 40 hexadecimal characters

• Example: 0x1234567890abcdef1234567890abcdef12345678

Non-EVM Chains

Solana

Solana NFTs are indexed via the MagicEden API.

Wallet Address Format:

• Base58 encoded string

• 32-44 characters long

• Example: 7EcDhSYGxXyscszYEp35KHN8vvw3svAuLKTzXwCFLtV

Tezos

Tezos NFTs are indexed via the OBJKT API.

Wallet Address Format:

• Starts with tz1, tz2, or tz3

• 36 characters total

• Example: tz1VSUr8wwNhLAzempoch5d6hLRiTh8Cjcjb

Chain Selection Tips

When backing up NFTs:

1. Know your wallet type: Different wallets support different chains

2. One chain at a time: Each backup request scans a single chain

3. Check marketplace presence: NFTs must be indexed by the marketplace API to be discovered

NFTs on chains not listed here cannot currently be backed up through the NFT Backup feature. Contact support if you need a chain added.

Chain-Specific Notes

Layer 2 Networks

Layer 2 networks (Arbitrum, Optimism, Base, etc.) use the same wallet address as Ethereum mainnet. You'll need to scan each network separately to back up NFTs on each layer.

Bridge Considerations

NFTs bridged between chains will appear on the destination chain only. The original chain will no longer show the bridged NFT.

Multi-Chain Collections

Some NFT collections exist across multiple chains. To fully back up such collections, run backups on each chain where you hold NFTs.
