Cross-chain DeFi protocols present network management requirements that single-chain protocols do not face. A protocol that operates on multiple Ethereum-compatible chains needs wallet integration logic that detects the user's current network, determines whether it matches the protocol feature the user is accessing, and manages network switching requests when a mismatch exists. For protocols that also support non-EVM chains, the network management layer needs to handle the different wallet types and connection protocols that non-EVM chains require, which may involve switching between MetaMask for EVM chains and Phantom for Solana, for example.
27 Blockchain's DeFi wallet integration service handles cross-chain network management as part of the integration scope for protocols that operate across multiple networks. The network detection and switching logic is configured to the specific chains the protocol supports, with network addition prompts for chains that users may not have configured in their wallets and context-appropriate network switching prompts that appear when the user accesses a protocol feature on a chain different from their current wallet network. For protocols adding cross-chain functionality to an existing single-chain integration, 27 Blockchain can extend the existing wallet integration to support the additional network requirements without rebuilding the core connection and transaction layers from scratch.
