# TypeScript SDKs

Tempo distributes TypeScript SDKs for:

* [Viem](https://viem.sh): TypeScript interface for EVM blockchains
* [Wagmi](https://wagmi.sh): React Hooks (and reactive primitives) for EVM blockchains

The Tempo extensions cover common chain operations such as querying state, sending Tempo Transactions, and managing tokens and AMM pools.

:::tip

**When should I use Wagmi vs. Viem?**

* **Viem** is best suited for **libraries, tooling, servers, scripting, etc** – a low-level and stateless interface for the EVM
* **Wagmi** is best suited for **applications & wallets** – a high-level and stateful interface for the EVM (React Hooks, Vanilla JS, etc)

## Viem

The T3-compatible `viem` release includes the updated access-key ABI, including periodic limits and call scoping. See the [T3 network upgrade](/docs/protocol/upgrades/t3) for migration details.
