+# extractChain
+
+Extracts a type-safe chain by ID from a set of chains.
+
+## Usage
+
+```ts
+import { extractChain } from 'viem'
+import { mainnet, base, optimism, zora } from 'viem/chains'
+
+const optimism = extractChain({
+  chains: [mainnet, base, optimism, zora],
+  id: 10,
+})
+
+optimism.id
+//       ^? (property) id: 10
+optimism.name
+//       ^? (property) name: "OP Mainnet"
+```
+
+It is also possible to use **all chains** from the `viem/chains` module:
+
+```ts
+import { extractChain } from 'viem'
+import { mainnet, base, optimism, zora } from 'viem/chains' // [!code --]
+import * as chains from 'viem/chains' // [!code ++]
+
+const optimism = extractChain({
+  chains: [mainnet, base, optimism, zora], // [!code --]
+  chains: Object.values(chains), // [!code ++]
+  id: 10,
+})
+
+optimism.id
+//       ^? (property) id: 10
+optimism.name
+//       ^? (property) name: "OP Mainnet"
+```
+
+::: warning
+By importing all chains from `viem/chains`, this will significantly increase the size of your bundle. It is only recommended to use this method where bundle size is not a concern (ie. server-side, scripts, etc).
+:::
+
+## Returns
+
+- **Type:** `Chain` (inferred)
+
+The extracted chain.
+
+## Parameters
+
+### chains
+
+- **Type:** `readonly Chain[]`
+
+The set of chains where the chain will be extracted from.
+
+### id
+
+- **Type:** `number`
+
+The ID of the chain to extract.
