How to Do Crypto.com Onchain Wallet Taxes: Not the Exchange App

Overview
Crypto.com is one brand with three different products, and for tax purposes they are not interchangeable. The Crypto.com App is a custodial exchange: you buy, sell and earn inside it, and Crypto.com holds the coins. The Crypto.com Exchange is the trading platform for larger volumes. The Crypto.com Onchain wallet — formerly the DeFi Wallet — is self-custody: you hold the keys, the coins sit on public blockchains, and Crypto.com cannot see or move them.
People use the App and the Onchain wallet together, moving coins between them, and then import one and wonder why half their history is missing. The two have completely different histories in completely different places. This article covers which is which, how to import the Onchain wallet, and how the transfers between the two are read.
Two Products, Two Kinds of Record
The App's history belongs to Crypto.com. Every purchase, sale, Earn payout and card transaction is in its database, and the way to get it out is the App's own export or API — importing exchange data covers how that works for Crypto.com.
The Onchain wallet's history belongs to the blockchains. The wallet is a key manager: it generates an address on each network you enable, and everything you do with those addresses is public chain data. Crypto.com has no export for it that is any better than the chain itself, and a tax tool reads the addresses directly.
So the two imports are separate, use different methods, and both are needed.
What You Can Import From the Onchain Wallet
Choosing Crypto.com Onchain in the CryptoTaxBridge import flow lists the networks it reaches:
| Family | Networks |
|---|---|
| EVM | Ethereum, Polygon, Arbitrum One, Linea, Gnosis, Avalanche, Blast, Mantle, Sonic, Unichain, opBNB, Berachain, Taiko, World Chain |
| Bitcoin-style | Bitcoin, Litecoin, Dogecoin |
| Other | Solana, XRP Ledger, Cardano |
The EVM networks share one 0x address. Open any EVM asset in the wallet, tap Receive, copy it, and the same string is your address on every EVM network — import it on each one you used.
One honest gap: Cronos, Crypto.com's own EVM network, is not among the networks that can be imported today. If you used the Onchain wallet on Cronos, that activity is not yet covered; keep its history from a Cronos explorer until support arrives.
Import an Onchain wallet address
Bitcoin in the Onchain Wallet
For Bitcoin, Litecoin and Dogecoin the wallet generates a new receiving address for each transaction, so the one under Receive holds only part of the history. Why one Bitcoin address is almost never your full history explains the problem; the fix is the extended public key, which covers every address the wallet has generated. Check the wallet's settings for the asset to see whether it displays the key; if it does not, import each address you have received on.
Transfers Between the App and the Wallet
This is the movement that causes the most confusion, and it is the simplest to explain.
Sending coins from the Crypto.com App to your Onchain wallet is a withdrawal from a custodial account to your own wallet. You owned them before and you own them after. It is not a disposal — HMRC treats beneficial ownership as unchanged, and most other tax authorities agree.
But it has two halves in two places. The App records a withdrawal, with the fee it charged. The chain records a deposit arriving at your address from a Crypto.com address. Import both, and the two halves match into one transfer. Import only the wallet, and the coins appear from nowhere with no cost basis — the purchase that gave them a cost basis happened in the App. Import only the App, and the coins vanish into a withdrawal and the later sale from the wallet is never seen.
The withdrawal fee the App charges is a real cost. How wallet transfers are treated covers the position on self-transfers in more detail.
Swaps, DeFi and Earn Inside the Wallet
The Onchain wallet has a built-in swap and connects to decentralised applications. A swap is a disposal of the asset you give and an acquisition of the one you receive, at that day's values — exchanging one cryptoasset for another is explicitly a disposal under HMRC's guidance, and the IRS treats it the same way. On the chain it is a single transaction from your address, and it imports as an exchange with the gas fee attached.
The wallet's own Earn feature lets you stake or lend from self-custody. Rewards are typically income at the value when received, and that value becomes the cost basis of the coins. This is separate from Earn in the App, which is a custodial product whose payouts are in the App's records.
Gas on every EVM transaction is a small disposal of the network's coin and an allowable cost of the transaction — whether gas fees are deductible covers the detail.
Review wallet swaps
Spam and Review
A self-custody address receives whatever anyone sends it. Importing an EVM or Solana address brings in unsolicited airdrops, dust and tokens that exist only to lure people to a scam site. The wallet hides unknown tokens; the chain does not. CryptoTaxBridge does not filter these automatically, because automated spam detection removes real transactions often enough to be dangerous. Each imported transaction can be reviewed, deleted and restored.
A Crypto.com Onchain Checklist
Before generating a report, confirm:
- the Crypto.com App (and the Exchange, if used) is connected as its own source;
- the Onchain wallet's EVM address is imported on every network you used it on;
- Bitcoin-style coins are covered by every address used, or by the extended public key;
- withdrawals from the App match the arrivals in the wallet as transfers;
- swaps show as exchanges of one asset for another, with gas attached;
- Earn rewards from the wallet appear as income with dates;
- spam tokens have been reviewed and removed.
Conclusion
One brand, two histories. The App's lives with Crypto.com and comes in through its export; the Onchain wallet's lives on the chains and comes in by address. Import both, and the transfers between them stop looking like money appearing and disappearing. Import one, and the report is wrong in a way that is hard to see until the balance does not add up.
