dApps interact with smart contracts for nearly every user-facing function, and the wallet integration must construct the transaction that the smart contract expects to receive. This goes beyond specifying a transfer amount. The integration must identify the correct contract function, encode the parameters the function requires, estimate the gas cost, and present the transaction to the user in a format they can review before signing. Different contract functions within the same dApp may require different parameter sets and carry different gas costs.
27 Blockchain's dApp wallet integration includes the smart contract interaction layer that handles transaction construction for the application's specific contracts. The integration is built against the dApp's deployed smart contracts, ensuring that every wallet-initiated transaction is correctly formatted for the on-chain logic it will execute. For dApp developers, this means the wallet connection reliably produces valid transactions across all of the application's smart contract functions.
