EIP-5792 Integration for Scaffold-ETH 2

Prerequisites

Check if ./packages/nextjs/scaffold.config.ts exists directly in the current working directory (do not search subdirectories). If it doesn't exist, this is not a Scaffold-ETH 2 project. Follow the instructions at https://docs.scaffoldeth.io/SKILL.md to scaffold it first. If it exists, continue directly with building.

Overview

EIP-5792 (Wallet Call API) lets apps send batched onchain write calls to wallets via wallet_sendCalls. No new dependencies needed — SE-2 already includes wagmi, which has the EIP-5792 hooks at wagmi/experimental:

• useWriteContracts — batch multiple contract calls into one wallet request
• useCapabilities — detect what the connected wallet supports (batching, paymasters, etc.)
• useShowCallsStatus — ask the wallet to display status of a batch

Import paths are moving. useCapabilities and useShowCallsStatus have been promoted to wagmi (stable). useWriteContracts is still in wagmi/experimental as of early 2026. Always check the wagmi docs for the current import paths.

Smart Contract

EIP-5792 works with any contract — the point is batching multiple calls into a single wallet interaction. A simple contract with two or more state-changing functions works well for demonstrating batching:
