SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Read contract data in a type-safe way by querying views and pure functions via a defined ABI, reducing runtime errors and mismatched types.

Core Features & Use Cases

  • Type-safe reads: query balanceOf, totalSupply and other view functions using a defined ABI.
  • Flexible read options: specify blockTag, blockNumber, and chainId to target historical or cross-network data.
  • Seamless integration: works with Wagmi readContract and readContracts patterns in client apps to fetch on-chain data.

Quick Start

Query a contract's read-only data by supplying a typed ABI, contract address, and function arguments.

FAQPage Schema
How do I read Ethereum contract state in a type-safe way using wagmi?▼

To read Ethereum contract state type-safely with wagmi, supply a typed ABI to the readContract function. This fetches on-chain data via view or pure functions while reducing runtime type mismatch errors.

Can I query historical contract data at a specific block number using wagmi?▼

Yes, you can query historical contract data by specifying blockTag or blockNumber options. This targets specific blocks when reading contract state across networks using wagmi core readContract calls.

How do I fetch data from multiple Ethereum contracts across different chains?▼

Fetch data from multiple contracts across chains by using the readContracts pattern with a typed ABI and chainId. This allows querying cross-network on-chain state safely within client applications.

Do I need a typed ABI to call view functions like balanceOf with wagmi?▼

Yes, a typed ABI is required to safely call view functions like balanceOf or totalSupply. Using a defined ABI ensures type safety when querying contract reads and prevents mismatched argument types.

What is the best way to prevent type mismatch errors when reading Ethereum contract data?▼

The best way to prevent type mismatch errors is querying contract data with a type-safe ABI. Defining typed ABI inputs ensures arguments match expected types when calling view and pure functions.

Why are my wagmi readContract calls returning mismatched types in my frontend?▼

Mismatched types occur when querying contract data without a properly defined typed ABI. Supplying typed ABI inputs for view and pure function calls ensures type safety and prevents runtime errors.
