Importing Crypto Data From Bybit, OKX, KuCoin, MEXC and Other Exchanges

Overview

A crypto tax report becomes more difficult the moment activity is split across several exchanges. A purchase may occur on one platform, a trade on another, and a final disposal on a third. Looking at each platform separately can leave gaps exactly where cost basis, wallet movements, or annual holdings need to be explained.

CryptoTaxBridge exposes API import connections for Bybit, OKX, Gate.io, Kraken, Crypto.com Exchange, Bitget, BingX, KuCoin and MEXC, alongside Binance and Coinbase. This article focuses on organising data from those exchanges into a single reporting workflow.

Why Multiple Exchanges Create Reporting Gaps

An exchange normally knows what happened on its own platform. It does not necessarily know why assets arrived from elsewhere or what occurred after a withdrawal.

Consider a simple chain:

1. you buy an asset on one exchange;
2. withdraw it to a personal wallet;
3. deposit it into another exchange;
4. trade or sell it there.

The final exchange may contain the disposal but not the original acquisition cost. The first exchange may contain the purchase but not the final sale. A reliable tax history requires both sources and the transfer path between them.

This is not a niche problem. Multi-exchange activity is ordinary in crypto, which is why centralised record keeping matters.

Supported API Connections in This Workflow

In the current CryptoTaxBridge application, the API import selector includes:

Exchange	API import	CSV upload	Passphrase needed
Binance	Yes	Yes	No
Bitget	Yes	Yes	Yes
BingX	Yes	Yes	No
Bybit	Yes	Yes	No
Coinbase	Yes	Yes	No
Crypto.com Exchange	Yes	Yes	No
Gate.io	Yes	Yes	No
Kraken	Yes	Yes	No
KuCoin	Yes	Yes	Yes
MEXC	Yes	No	No
OKX	Yes	Yes	Yes

Two things in that table are worth noticing before you start. OKX, KuCoin and Bitget ask for an API passphrase alongside the key and secret, so the connection form shows a third field for those three. And MEXC is API-only — there is no CSV route for it, so the API connection is the way in.

Each exchange also differs in API structure, how much history it exposes, and what it omits.

The purpose of supporting multiple exchanges is not to claim that every dataset is identical. It is to make it possible to assemble more of the transaction trail in one reporting environment. For choosing between connection types, see API import and CSV upload compared.

Connect supported exchanges

Always Use Read-Only Credentials

For every API connection, use credentials configured for reading history only. Never enable trading or withdrawals for a tax-import connection.

A responsible setup includes:

• creating a separate key for reporting use;
• limiting it to required read permissions;
• never granting withdrawal permission;
• never granting trading permission;
• storing secrets carefully;
• revoking keys that are no longer used.

CryptoTaxBridge presents the same principle in its import interface: read-only keys should be used, and trading or withdrawals should not be enabled.

Some exchanges expose permission verification more clearly than others. The safe user behaviour remains the same across all of them: give the import the smallest permission set necessary to read history.

What to Look for After Importing Each Exchange

Once transactions have been imported, do not jump directly to report generation. Review the data source by source.

Bybit

Review spot or conversion activity, deposits, withdrawals, and any other imported movements relevant to your account history. Check whether earlier or external activity is needed to establish the origin of deposited assets.

OKX

Confirm that the connected account and passphrase were correct, then review trades, funding movements, deposits, and withdrawals included in the imported history. Assets moving through different OKX account areas may require careful review in the full timeline.

Gate.io

Review imported transactions across the activity actually used in your account. Deposits or withdrawals may reveal that the acquisition or disposal side of a holding exists elsewhere.

Kraken

Check ledgers, trades, deposits, withdrawals, and the relationship between incoming crypto and later disposals. A Kraken sale without an acquisition history from the original source should be investigated before reporting.

Crypto.com Exchange

Review trades, conversions, deposits, and withdrawals included through the Exchange connection. Make sure you are working with Crypto.com Exchange history where that is the connected product, rather than assuming it automatically represents every product or wallet under the broader Crypto.com brand.

Bitget

A passphrase is required alongside the key and secret. Review spot trades, conversions, deposits and withdrawals. If you have used products beyond spot, check whether that activity appears in the imported history or needs separate evidence.

BingX

Review spot activity and the transfers in and out of the account. As with any exchange offering derivatives or copy trading, do not assume that non-spot activity maps cleanly onto an investment disposal record without review.

KuCoin

A passphrase is required here too. KuCoin separates funds across account types, and movements between your own main and trading accounts are internal transfers rather than disposals — check that they have not been read as taxable events.

MEXC

Review spot trades, deposits and withdrawals. Where an account has a long history, confirm the imported range actually reaches back to the acquisitions behind your disposals rather than stopping short.

Transfers Must Be Connected, Not Taxed Twice

A multi-exchange history commonly includes a withdrawal from one exchange and a deposit into another. Where both belong to you, this may be an internal transfer rather than a disposal.

The review task is to determine whether movements connect:

• compare assets and quantities;
• check timing;
• examine network fees;
• confirm destination wallets where available;
• ensure the asset's acquisition history is preserved.

Failing to link transfers can cause two opposite problems: treating a non-taxable internal movement as a taxable event, or failing to identify a genuine disposal sent to another party.

Organise exchange history

One Imported History, Different Country Reports

Once exchange data has been assembled and reviewed, it can support reporting under the selected country method. CryptoTaxBridge currently provides report options for:

• United Kingdom;
• United States;
• Netherlands;
• Ireland;
• Australia;
• Canada.

The imported trade history does not change, but the tax logic does. UK reporting applies HMRC matching and Section 104 pooling support. US reporting uses FIFO support with holding-period categories. Canadian reporting uses pooled adjusted cost base under the capital-account assumption. Dutch reporting focuses on Box 3 support information.

That separation matters. Importing data is the plumbing; tax rules are the architecture. Confusing them is how otherwise impressive dashboards end up confidently wrong.

Import Coverage Checklist

Before preparing a multi-exchange report, confirm that you have:

1. connected every relevant supported exchange account;
2. used read-only permissions only;
3. reviewed deposits and withdrawals between sources;
4. identified personal wallets not covered by exchange imports;
5. checked for missing acquisitions behind disposals;
6. reviewed unusual or duplicated movements;
7. selected the correct reporting country and tax period.

A multi-exchange report should tell one coherent story about the assets. If there are gaps in that story, investigate before relying on the totals.

Note on Additional Exchange Support

CryptoTaxBridge may include additional integration work in the backend or future product versions. This article describes exchange connections currently exposed to users in the application interface. Features should be advertised only when a user can actually access them — a radical concept in software marketing, yet surprisingly effective.

Conclusion

Using more than one exchange does not have to turn crypto tax reporting into a manual reconciliation nightmare. The solution is to bring transaction histories together securely, review transfers and missing links, and then apply the correct country-specific reporting method.

Start with read-only imports. Complete the transaction chain. Review before generating a report. The result is more reliable records and fewer unpleasant questions at filing time.
