zkSync
Viem provides first-class support for chains implemented on zkSync.
Chains
The following Viem chains are implemented on zkSync:
ts
import {
zkSync,
zkSyncTestnet,
} from 'viem/chains'import {
zkSync,
zkSyncTestnet,
} from 'viem/chains'Configuration
Viem exports zkSync's chain formatters & serializers via chainConfig. This is useful if you need to define another chain which is implemented on zkSync.
ts
import { defineChain } from 'viem'
import { chainConfig } from 'viem/zkSync'
export const zkSyncExample = defineChain({
...chainConfig,
name: 'zkSync Example',
// ...
})import { defineChain } from 'viem'
import { chainConfig } from 'viem/zkSync'
export const zkSyncExample = defineChain({
...chainConfig,
name: 'zkSync Example',
// ...
})Utilities
serializeTransaction
Serializes a transaction object. Supports EIP-712, EIP-1559, EIP-2930, and Legacy transactions.
zkSync-flavored version of Viem's serializeTransaction.
Parameters
transaction(TransactionSerializable): The transaction object to serialize.signature(Signature): Optional signature to include.
