Blockpit showing "Unlabeled" warnings in your transaction list? You're not alone. Especially with DeFi activities, bridge transfers, and unknown tokens, Blockpit cannot automatically recognize the transaction type. This guide shows you step by step how to identify unlabeled transactions, classify them correctly, and bring your crypto documentation up to a clean standard.

01 What Does "Unlabeled" Mean in Blockpit?

Blockpit marks transactions as unlabeled when it cannot automatically recognize the transaction type. This happens when Blockpit imports a transaction from a wallet or exchange but cannot determine whether it's a trade, deposit, withdrawal, or another category.

This primarily affects DeFi smart contracts, bridge transfers between blockchains, and unknown tokens that Blockpit doesn't have in its database. With DeFi-active portfolios, typically 30%+ of all transactions are affected. Automatic recognition reaches its limits here because the underlying transactions are more complex than simple exchange trades.

A concrete example: You use CoWswap for a token swap. Blockpit imports the transaction via wallet sync but classifies it as "Unlabeled". Without correct classification, the swap is missing from the tax calculation. The result: an incorrect total in the tax report.

Important to understand:

Unlabeled is not an error

The transaction was imported correctly. Only the type was not recognized. You must assign it manually.

Tax-relevant

Unlabeled outflows are treated by Blockpit as sales. Unlabeled inflows receive a cost basis of 0 EUR – both scenarios distort the tax calculation.

Mainly affects DeFi

Smart contract calls, liquidity pools, and cross-chain bridges & swaps are the most common causes of unlabeled transactions.

Impact on calculation

Unlabeled outflows = sale, unlabeled inflows = cost basis 0 EUR. Both scenarios lead to incorrect tax results.

Blockpit Fallback Notice:

What does "Fallback" as a note mean?

When Blockpit adds the note "Fallback" to a transaction, automatic classification could not be applied. The transaction requires manual review and correct classification. Without correction, outflows are treated as sales and inflows with a cost basis of 0 EUR.

02 Which Transactions Are Frequently Unlabeled?

Not every transaction is marked as unlabeled. Simple exchange trades and transfers are usually recognized correctly by Blockpit. The problems begin where blockchain activity becomes more complex.

DeFi Interactions

Swaps on decentralized exchanges like CoWswap or Jupiter, lending deposits on Aave or Compound, and yield farming are the most common sources of unlabeled transactions. Blockpit recognizes the smart contract but cannot always derive the transaction type.

Cross-Chain Bridges

Bridge transfers via protocols like Wormhole, LayerZero, or Multichain create transactions on two different blockchains. Blockpit often sees only one side of the transfer and cannot automatically establish the connection.

Wrapped Tokens and Governance

Wrapped token interactions (e.g., WETH to ETH or wBTC), governance actions like voting and delegating, as well as unknown airdrops are also frequently imported as unlabeled. This is especially true for contracts that Blockpit doesn't know in its database.

  • DeFi Swaps – CoWswap, SushiSwap, Jupiter, Raydium
  • Lending/Borrowing – Aave, Compound, MakerDAO
  • Bridges – Wormhole, LayerZero, Multichain, Stargate
  • Wrapped Tokens – WETH, wBTC, stETH
  • Governance – Voting, Delegating, Claiming
  • Airdrops – Unknown token deposits without context

⚡ Quick Reference: Unlabeled Transaction Types & Typical Labels

Transaction Type Typical Cause Typical Label Tax Impact
DeFi Swap CoWswap, SushiSwap, Jupiter Trade Taxable disposal event
Bridge Transfer Wormhole, LayerZero, Stargate Deposit/Withdrawal Tax-neutral if correctly linked
Lending Aave, Compound, MakerDAO Deposit + Interest Interest is taxable income
Staking Reward ETH Staking, Lido, Rocket Pool Staking Reward Income at time of receipt
Airdrop Unknown token deposits Airdrop or Spam Taxable unless marked as spam
Wrapped Token WETH ↔ ETH, wBTC Swap Technical wrapping, typically no real gain/loss

03 Step by Step: Fix Unlabeled Transactions

The process is systematic. Go through the following steps in order to clean up all unlabeled transactions in Blockpit.

Step 1: Filter All Unlabeled Transactions

Open the transaction list in Blockpit and use the filter function. Filter by the status "Unlabeled" to see all affected entries at a glance. This gives you an overview of the scope and allows you to proceed systematically.

Step 2: Identify Transaction Type

For each unlabeled transaction, you need to find out what actually happened. Use the blockchain explorer of the respective chain (e.g., Etherscan for Ethereum, Solscan for Solana). Search for the transaction hash and check: Which smart contract was called? What was the function? Is it a swap, deposit, withdrawal?

Step 3: Assign Appropriate Label

Assign the label in Blockpit that technically and correctly represents the actual transaction. Blockpit offers various categories such as Trade, Deposit, Withdrawal, Staking Reward, Interest, Reward, and more. Which label is correct depends on the specific case — what matters is what actually happened on the blockchain. When in doubt, cross-reference with the blockchain explorer from Step 2.

Step 4: Mark Scam Tokens

If you find tokens in your wallet that you never bought or received, they are probably scam airdrops. Mark these in Blockpit as "Spam" or change the ticker. This way they won't be recorded as taxable income. Never interact with unknown tokens – it can be a security risk.

Step 5: Trigger Recalculation

After you have assigned all labels, manually trigger the recalculation via the button in Blockpit. Only after recalculation do the corrected labels flow into the tax report. Check afterwards whether new warnings or errors have emerged.

04 Label DeFi Transactions Correctly

DeFi transactions are the most common cause of unlabeled entries. Here's an overview of how to correctly classify the most important DeFi categories.

Lending (Aave, Compound)

Lending protocols have three transaction types: The deposit into the protocol is labeled as Deposit. The repayment (withdrawal of the deposited amount) as Withdrawal. And the interest you receive as Interest. Make sure that deposit and repayment are correctly linked so no false profit is created.

Liquidity Pools

When you deposit tokens into a liquidity pool, you receive LP tokens. This deposit is a trade (tokens for LP tokens). Rewards you receive from the pool are classified as Reward. When exiting the pool, you exchange the LP tokens back – again a trade.

Staking

The deposit for staking is labeled as Staking. Rewards you regularly receive as Staking Reward. Unstaking (withdrawal) is the corresponding counter-entry. With liquid staking (e.g., stETH), an additional token is created that must be recorded as a trade.

Bridges

Cross-chain bridges & swaps create two unlinked transactions: an outflow on chain A and an inflow on chain B. In Blockpit, both sides must be correctly marked as belonging together and linked to a transfer.

DeFi Label Suggestions:

Lending

Deposit = Transfer | Repayment = Transfer | Interest = Interest

Liquidity Pools

Receive LP tokens = Trade/Swap | Rewards = Income | Exit = Trade/Swap

Staking

Deposit = Transfer | Rewards = Staking Reward | Unstaking = Transfer

Bridges

Outflow Chain A = Transfer | Inflow Chain B = Transfer

05 Special Cases and Common Errors

Some transaction types require special attention because they are easily misclassified. You should know these special cases.

Wrapped Tokens: Not a Taxable Trade

The exchange of WETH to ETH (or vice versa) is a technical wrapping/unwrapping. In Blockpit, this process is classified as a Swap. Since the value is identical, no real gain or loss is created. The same applies to wBTC to BTC.

Scam Airdrops: Don't Label as Income

Scam tokens that land in your wallet unsolicited should never be classified as income. Mark them in Blockpit as spam or change the ticker to a placeholder. Otherwise, Blockpit calculates a taxable inflow that isn't one. Special caution: Some scam tokens have artificially inflated prices in data feeds.

Failed Transactions: Only Gas Costs Relevant

A failed transaction (status: "Failed" in the blockchain explorer) has not transferred any value. The gas costs were still incurred and can be considered as transaction costs depending on the legal view. The transaction value itself is irrelevant and should not be recorded as a trade.

Multi-Step DeFi (Zap Functions)

Some DeFi protocols bundle multiple actions in one transaction – so-called zap functions. For example: Swap + deposit into a liquidity pool in one step. In Blockpit, each step must be checked individually and labeled correctly. A zap can contain a trade and a deposit simultaneously.

06 The Logic Chain: Why Correct Labels Matter

Unlabeled transactions are not just a display problem in Blockpit. They have direct impacts on the entire chain from crypto documentation to compliance.

The Dependency:

1.

Crypto Documentation

Every transaction needs a correct label. Unlabeled entries create gaps in the documentation.

2.

Tax Calculation

Blockpit calculates gains and losses based on the labels. Missing or incorrect labels distort the result.

3.

Compliance

The tax report is only as correct as the underlying documentation. In case of inquiries, you need comprehensible data.

Unlabeled transactions are like missing puzzle pieces. Without them, the picture is incomplete — and every calculation based on this is uncertain.

A single unlabeled transaction may seem insignificant. But in practice, unlabeled entries lead to chain reactions: missing cost basis, incorrect balance calculations, and in the worst case, negative balances that cause further errors. The earlier you correct the labels, the more stable the entire documentation becomes.

07 What Unlabeled Transactions Mean for Your Tax Return

Unlabeled transactions are not just a technical issue in Blockpit — they have direct tax consequences. Tax authorities in Austria and Germany expect complete and comprehensible documentation of all crypto transactions.

⚠️ Tax Risk Assessment: Unlabeled Transactions

Scenario Tax Consequence Legal Basis Risk
Unlabeled outflows as sales Inflated capital gains § 27 EStG (AT) / § 23 EStG (DE) High
Inflows with 0 EUR cost basis 100% taxable profit on disposal § 27a EStG (AT) / § 23 EStG (DE) High
Missing bridge link Double taxation of same asset § 162 AO / BAO § 184 Medium
Incomplete documentation Tax estimation by authority § 162 AO / BAO § 184 High

Since the DAC8 directive came into effect in January 2026, crypto exchanges automatically report transaction data to EU tax authorities. Gaps in documentation are therefore noticed more quickly than ever. If you receive an inquiry from the tax authority, comprehensible documentation is your most important evidence.

08 When Professional Help Makes Sense

You can fix individual unlabeled transactions yourself. But there are situations where the effort or complexity exceeds the scope of self-help.

With Hundreds of Unlabeled Transactions

When Blockpit marks dozens or hundreds of transactions as unlabeled, manual classification becomes extremely time-consuming. Looking up each individual transaction in the blockchain explorer and labeling it correctly can quickly take days with an active DeFi portfolio.

With Complex DeFi Portfolios

Those active on multiple chains, using various DeFi protocols, and regularly using bridges have a portfolio that requires special expertise. The linking of cross-chain transfers, correct allocation of LP token rewards, and tracking of liquid staking are tasks where errors quickly lead to incorrect tax calculations.

Frequently Asked Questions About Blockpit Unlabeled Transactions

What does "Unlabeled" mean in Blockpit?

Blockpit marks transactions as unlabeled when the transaction type cannot be automatically recognized. This particularly affects DeFi interactions, smart contract calls, and unknown tokens.

How can I find unlabeled transactions in Blockpit?

Use the filter function in the transaction list. Filter by the status "Unlabeled" to display all affected entries.

Are unlabeled transactions tax-relevant?

Yes, every unlabeled transaction is tax-relevant. Unlabeled outflows are treated by Blockpit as sales, unlabeled inflows receive a cost basis of 0 EUR. Both scenarios significantly distort the tax calculation.

What should I do with scam airdrops in Blockpit?

Scam airdrops should be marked as spam or have their ticker changed so they are not recorded as taxable income.

How many unlabeled transactions are normal?

For wallets with DeFi activity, 10–30% unlabeled transactions are common. With pure exchange imports, however, there should be almost no unlabeled entries. A high proportion indicates missing API data or unsupported protocols.

Can I retroactively classify unlabeled transactions?

Yes, Blockpit allows retroactive classification at any time. After assigning labels, trigger a recalculation to update the tax report. Under Austrian and German tax law, you are even obligated to correct incorrect information (§ 153 AO / BAO § 139).

What happens if I ignore unlabeled transactions?

Unlabeled outflows are treated by Blockpit as taxable sales, unlabeled inflows receive a cost basis of 0 EUR. This means significantly inflated tax liabilities. Since the DAC8 directive (from January 2026), exchanges automatically report to tax authorities — gaps are quickly noticed.
