How to find your Sui public address
Your Sui public address allows you to receive and track your SUI tokens.
Mobile wallets (e.g., Sui Wallet, Martian, Ethos, Suiet):
Open your wallet app.
Select your Sui account.
Tap Receive.
Copy the public address displayed (starts with 0x...).
Browser wallets (e.g., Sui Wallet extension, Martian, Ethos):
Click on the wallet extension.
Confirm that the Sui Mainnet is selected.
Click Receive or Account → copy your address (begins with 0x).
Hardware wallets (e.g., Ledger):

In the companion app (such as Sui Wallet or Ethos), click Receive.

Your public address can be safely shared for deposits or tracking, but never share your recovery phrase or private key.
How are Sui transactions taxed?
Sui (SUI) is treated as property for tax purposes. The taxable implications depend on your activity type:
Buying SUI with fiat (USD, MXN, etc.) – Not taxable; establishes your cost basis.
Selling SUI for fiat – Taxable capital gain/loss = sale proceeds − cost basis.
Swapping SUI for other crypto assets – Taxable event; the disposed asset triggers a gain or loss.
Spending SUI on goods, services, or NFTs – Taxable as a crypto disposal.
Staking rewards – Counted as ordinary income at the time received; later sales create capital gain/loss.
Airdrops, node rewards, or ecosystem incentives – Typically ordinary income upon receipt.
Bridging or transferring SUI between your own wallets – Non-taxable if ownership remains the same.
Gas fees – May adjust your cost basis or proceeds depending on the context of the transaction.
CoinTracker automatically detects and classifies your Sui transactions, ensuring accurate capital gain and income calculations.
Can the IRS track Sui?
Yes. The Sui blockchain is fully transparent and all transactions are recorded on-chain. The IRS and other authorities can:
Analyze wallet activity using blockchain forensics tools.
Receive tax reports (like 1099 forms) from KYC-compliant exchanges and custodians.
Match wallet addresses to user data shared by centralized platforms.
Using CoinTracker helps you stay compliant by maintaining a clear and accurate record of all Sui transactions.
