How are EtherFlyer transactions taxed?
All EtherFlyer transactions — including swaps and trades executed via smart contracts — are taxable events under most tax systems.
Capital gains tax: Applies when you swap or trade tokens. Each trade is a disposal event, and the gain equals the difference between your cost basis and the token's fair market value at the time of the trade.
Income tax: Applies when you receive tokens through airdrops, referrals, or rewards distributed via EtherFlyer or partner projects. The token's market value at receipt is considered taxable income.
CoinTracker analyzes your on-chain EtherFlyer trades and classifies them automatically for accurate capital-gain and income reporting.
Do I have to pay taxes on EtherFlyer trades?
Yes. Even though EtherFlyer operated as a non-custodial decentralized exchange, all token swaps and sales are considered taxable disposals. You must report:
ERC-20 token swaps (e.g., DAI → USDC, ETH → LINK)
Trades involving ETH or wrapped ETH (WETH)
Rewards or airdrops from EtherFlyer or listed tokens
CoinTracker scans your wallet activity on the Ethereum blockchain to identify all EtherFlyer-related trades and automatically calculates your taxable events.
Does EtherFlyer provide tax documents?
No. As a decentralized exchange, EtherFlyer did not issue official tax documents such as Form 1099-B or account statements.
However, all your trading data remains publicly visible on the Ethereum blockchain.
You can import your wallet address into CoinTracker, which automatically fetches your on-chain EtherFlyer activity and generates a full tax summary.
How to get your EtherFlyer tax documents
Identify the Ethereum wallet you used for trading on EtherFlyer.
Visit a blockchain explorer such as Etherscan.io. Search your wallet address and filter for EtherFlyer contract interactions (usually tagged as EtherFlyer or ETHFLYER).
Export your transaction history as a CSV (if available).
Go to CoinTracker → Add Account → Wallet → Ethereum.
Paste your wallet address to automatically import your full on-chain activity.
When did EtherFlyer issue tax forms?
Never. EtherFlyer was a DEX and did not issue any tax forms, including Form 1099-MISC or 1099-B.
You are responsible for self-reporting your crypto trading and income to your tax authority.
CoinTracker automates this by creating Form 8949, Schedule D, and equivalent reports for your jurisdiction.
Why aren't my EtherFlyer reports accurate?
Your reports may appear incomplete if:
You used multiple Ethereum wallets.
Some transactions involved wrapped assets (WETH, WBTC) that weren't properly tagged.
You interacted with unverified EtherFlyer contract addresses or migrated liquidity elsewhere.
CoinTracker reconciles your on-chain data, matching every swap and token transfer to market prices for complete, audit-ready records.
Does EtherFlyer automatically deduct taxes?
No. EtherFlyer was a non-custodial DEX, so it never withheld or remitted taxes.
You are responsible for calculating and paying taxes on your realized profits and income.
CoinTracker automates this process by generating precise capital-gain and income summaries using blockchain data.
Does EtherFlyer report to tax authorities?
No. EtherFlyer was a decentralized protocol, meaning it did not collect user KYC data or report activity to tax authorities.
However, all activity on Ethereum is publicly traceable, so tax authorities can still analyze on-chain data.
CoinTracker ensures your reporting matches your on-chain record for full transparency and compliance.
Does EtherFlyer provide financial or end-of-year statements?
No. There are no official statements, but Etherscan and CoinTracker can reconstruct your year-end summaries based on your Ethereum transactions.
CoinTracker generates capital-gain, income, and portfolio reports automatically for your filing period.
