NFTs are minted on different blockchain networks, and a marketplace that supports assets on Ethereum, Solana, Polygon, and Base needs wallet integration that routes transactions to the correct chain. A buyer purchasing an Ethereum-based NFT must connect a wallet on Ethereum. A buyer purchasing a Solana-based NFT must connect on Solana. The wallet integration must detect which chain the target NFT lives on and guide the transaction accordingly.
27 Blockchain configures multi-chain NFT wallet integration to handle this routing within the platform's checkout flow. The integration detects the NFT's chain, verifies the buyer's wallet is connected to the matching network, and processes the transaction on the correct blockchain. This multi-chain capability allows the marketplace to list NFTs across multiple networks without requiring buyers to manually switch networks or manage chain-specific wallet configurations.
