viem, abitype & zod feel like me the same relative output increases that the early versions of nextjs did
really changing the landscape for new developers getting into crypto

viem.sh attempts to make errors as human readable & comprehensible as possible, here is a comparison of a `sendTransaction` error message if the account has insufficient funds:

Should I use wagmi or viem?
wagmi is for dapps & wallets – a high-level and stateful interface for Ethereum (React Hooks, Vanilla JS, etc)
viem is for libraries, tooling, server-side dev, scripting, etc – a low-level and stateless interface for Ethereum

We, the authors of wagmi, built viem because we knew a stable, predictable implementation with a tiny bundle size and performant modules was paramount to interacting the world's largest blockchain ecosystem.
You can learn more about our rationale here:

viem further tunes performance with optimized encoding/parsing algorithms, and by only executing heavy asynchronous tasks when required.

viem is 27kB.
End users should not be required to download over 100kB in order to interact with Ethereum.
viem is also tree-shakable, meaning only the modules you use are included in your final bundle.

Stability is a fundamental principle for viem.
- We run our test suite against a forked Ethereum node
- We aim for complete test coverage and test all potential behavioral cases
- We build deterministic and pure APIs

viem delivers a great developer experience through:
- Modular and flexible building blocks to build Ethereum apps with speed & stability
- Strongly typed APIs for autocompletion, type inference & static validation
- Fully documented APIs

viem will help developers build with a higher level of accuracy and correctness through type safety and developer experience.
It will also integrate extremely well with wagmi so folks can start using it without much upfront switching cost.

Human readable ABI is one of the most loved features of ethers js, which we also Reimplemented in ethers-rs with full abi v2 support.
Now also available in the stack, with Typescript magic to get types without codegen via abitype.

ABIType now supports Human-Readable ABIs
- Parsing works at the type-level and runtime
- Supports top-level `Structs`
- `parseAbi`, `parseAbiItem`, and more!

Foundry X will become the default web3 full stack development stack.
If you're building on either and are in Denver this week, hmu, have some ideas for the hackathon, also happy to provide support

still time this week to add `@wagmi/cli` to your app
automate abi management and stop writing boilerplate
( ͡° ͜ʖ ͡°)
Quote Tweet
npm i @wagmi/cli
Automatically manage ABIs, generate code, and much more!
No more copying pasting ABIs from Etherscan
Remove boilerplate code with generated React Hooks
Connect Foundry/Hardhat projects to your apps
Create and publish your own CLI plugins

solid primer on wagmi cli 👀

A quick introduction on how to use @wagmi_sh CLI and 
TurboETH so you never have to write smart contract react hooks again.
Personally I'm so done with actual coding. Can't wait for the day where all the focus is on problem => solution => product.

PSA: `useContractRead` and `useContractWrite` are much better than `useContract`.
