How to find your Ethereum public address
Your Ethereum public address is the "0x…" string visible in your wallet.
Mobile wallets (e.g., MetaMask, Trust Wallet, Coinbase Wallet):
Open the wallet app.
Select the Ethereum account/network.
Tap Receive or Account details.
Copy the address (starts with 0x).
Browser wallets (e.g., MetaMask extension):
Click the extension → make sure Ethereum Mainnet is selected.
Click the account name to copy your 0x… address.
Hardware wallets (e.g., Ledger, Trezor):
Open the Ethereum app on the device.
In the companion app, view the account and copy the 0x… address.
Tip: You can share this public address safely for tracking deposits; never share your seed phrase or private key.
How are Ethereum transactions taxed?
Tax treatment depends on the type of activity. Common cases include:
Buying ETH with fiat (USD, MXN, etc.) – Not taxable at purchase; establishes cost basis.
Selling ETH for fiat – Taxable capital gain/loss = proceeds − cost basis.
Swapping ETH ↔ tokens (ERC-20) or token ↔ token – Taxable disposition of the asset you give up; the received asset's fair market value becomes new basis.
Spending ETH/tokens on goods/services or NFT mints – Taxable (treated like selling the crypto used to pay).
Staking rewards (solo, pooled, liquid staking like LSTs) – Typically ordinary income at fair market value when received; later disposal triggers capital gain/loss.
Airdrops/claim rewards – Generally ordinary income at receipt; later disposal = capital gain/loss.
Bridging / transfers between your own wallets – Usually non-taxable if you maintain control and it's the same beneficial ownership.
Gas fees – May adjust basis or proceeds (e.g., added to basis when acquiring, reduce proceeds when disposing) depending on context.
CoinTracker classifies these actions, tracks basis lots (FIFO/other settings), and computes gains, losses, and income automatically.
Can the IRS track Ethereum?
Yes. Ethereum is a public blockchain with transparent on-chain data. The IRS can:
Analyze wallet flows using blockchain analytics.
Receive information returns (e.g., 1099 forms) from KYC exchanges/custodians.
Use summons/subpoenas to obtain records.
Accurate tracking and reporting with CoinTracker helps you stay compliant.
