Biconomy smart accounts are smart contract wallets that can batch the transactions and have different fee mechanism.
Just like ethers.js or web3.js needs a Transaction Request (for destination contract and action on this smart contract) , Biconomy SDK allows to input single transaction or array of transactions from a Dapp developer.
Relayer then triggers this above transaction / batch on user's Smart Account to interact with multiple contracts in one-click (just a signature!) Fee Mechanism 1. Gasless (Account Abstraction Paymasters) 2. Make your user pay the fees ( in tokens help by the wallet)
