What people use it for
ZKsync Era in practice.
ZKsync Era is the original ZK rollup of the ZKsync network, which now targets institutions, privacy and tokenised assets.
- Swaps and transfers across the apps on the chain
- Bridging in and out from Ethereum and other networks
- Gas paid on every transaction

Good to know
ZKsync Era specifics.
- One 0x address works across EVM networks, ZKsync Era included, but each network records its own transactions. Add your address once more for ZKsync Era.
- ZKsync Era is an Ethereum layer 2. Bridging ETH or tokens from Ethereum moves your own assets, so HashBooks records it as a transfer with the original cost carried over, not a sale.
- The base token of ZKsync Era Mainnet (chain ID 324) is ETH, and its data availability layer is Ethereum.
- The ZK token is used for governance. Era is where the ZK token was initially deployed and where on-chain governance takes place.
- Batch proofs are submitted to Ethereum, where a contract verifies them and finalizes state transitions.

Questions
ZKsync Era, answered.
Is bridging to ZKsync Era taxable?
Moving your own crypto to ZKsync Era through a bridge is generally not a sale, because you still own it. Watch for bridges that swap the token on the way: receiving a different asset can be a disposal. HashBooks matches the two sides when both addresses are connected.
Are ZKsync Era gas fees tax deductible?
It depends on your country. In the US and UK a fee paid on a trade usually becomes part of its cost or reduces proceeds; in India only the cost of acquisition is deductible. HashBooks applies the rule for the country you file in.
Which HashBooks plan do I need for ZKsync Era?
Connecting ZKsync Era and seeing an estimated tax summary is free for up to 100 transactions across 3 connections. Filing reports for your country start on the Starter plan; see pricing.
Can HashBooks move anything from my ZKsync Era address?
No. A public address shows history but can’t sign anything, and HashBooks never asks for a recovery phrase or private key. It reads; it can’t trade, withdraw or transfer.
