How to find your zkSync Era public address
Your zkSync Era address is the same as your Ethereum Layer 1 (L1) address since zkSync is an Ethereum Layer 2 (L2) scaling network.
Browser wallets (e.g., MetaMask, Rainbow, OKX Wallet):
Open your wallet extension.
Make sure you're connected to the zkSync Era Mainnet network.
Click Account or Receive.
Copy your 0x... address (same as your Ethereum address).
Mobile wallets (e.g., Argent, Zerion, Trust Wallet):
Open your wallet app.
Switch the network to zkSync Era Mainnet.
Tap Receive and copy your 0x... address.
Hardware wallets (e.g., Ledger):
Connect your device and open the Ethereum app.
Access zkSync through a supported interface (e.g., MetaMask, Argent).
Copy your 0x... public address.
This address can safely be shared for receiving funds or connecting to CoinTracker—but never share your private key or seed phrase.
How are zkSync Era transactions taxed?
zkSync Era (L2) transactions are taxed similarly to those on Ethereum (L1). Every taxable event depends on the nature of your activity:
Depositing from Ethereum (bridging to zkSync) – Non-taxable transfer (same ownership); may incur deductible gas fees.
Withdrawing from zkSync back to Ethereum – Non-taxable if you maintain ownership; track associated gas fees.
Buying crypto with fiat – Not taxable; establishes your cost basis.
Swapping tokens on zkSync (e.g., ETH → USDC) – Taxable disposal; gain/loss = received value − cost basis.
Spending tokens or minting NFTs – Taxable, as it involves disposing of crypto.
Earning rewards (staking, airdrops, liquidity mining) – Ordinary income at fair market value when received.
Bridging rewards or incentives (e.g., ZK token airdrops) – Taxable income upon receipt; later sale triggers capital gain/loss.
Transferring between your own zkSync wallets – Non-taxable, but important for cost basis tracking.
Gas fees (L1 or L2) – May be deductible from proceeds or added to basis depending on transaction context.
CoinTracker automatically classifies zkSync Era transactions and calculates capital gains, losses, and income across both L1 and L2 networks.
Can the IRS track zkSync Era?
Yes. zkSync Era operates on public blockchain technology. Even though it uses zero-knowledge proofs for scalability, transaction data and wallet balances are still verifiable on-chain. The IRS and other authorities can:
Use blockchain analytics tools to trace zkSync and Ethereum bridge transactions.
Receive user data from centralized exchanges or on-ramps that support zkSync.
Correlate L1 and L2 wallet activity linked to KYC-verified accounts.
Using CoinTracker ensures full visibility and compliance for all your zkSync Era and Ethereum activities.
