The **minter‑js‑web3‑sdk** is a JavaScript library that simplifies building, signing and broadcasting “smart‑wallet” transactions on the Minter blockchain, especially when interacting with Web3‑compatible dApps. It provides composable helpers for calculating smart‑wallet addresses, creating combined transactions (including fee‑paying ERC‑20 tokens), and integrating 1inch token swaps or relay‑reward mechanisms, making it useful for developers building Web3 front‑ends or services on Minter.
