Regulatory framing — United States

UNI swaps are reported on Form 1099-DA at US CEXes starting tax year 2025+. UNI's clean post-2025 regulatory profile (SEC Wells notice dropped Feb 2025) means no securities-law overhead at the platform level. Ethereum + L2 DEX swaps (Uniswap, 1inch, ParaSwap, OpenOcean) remain outside the broker-reporting regime — self-report on Form 8949. Every swap, including UNI ↔ stablecoin swaps, is a taxable disposal. DEX swap volume on UNI is exceptionally high (it's the governance token of the largest DEX) — crypto-tax software with Ethereum + L2 wallet-address ingestion is functionally mandatory for active UNI holders.

Common gotchas

Recursive economics: swap UNI on Uniswap. The DEX that pays you to provide UNI liquidity is the same DEX whose governance you control via UNI. Tax-wise no different; mechanically interesting context.
DEX execution is genuinely competitive with CEX for UNI. Uniswap UNI ↔ ETH + UNI ↔ USDC are top-20 by pool depth on Uniswap itself — tight spreads + minimal price impact for retail-size trades.
Specific-ID lot selection on multi-cycle UNI swaps. Airdrop ($3.50), 2021 peak ($30-$45), 2022-2023 low ($3-$5), 2024-2025 ($6-$15). FIFO usually sells lowest-basis first; specific-ID HIFO minimizes realised gain.
Wash-sale rule does NOT apply to crypto. UNI → another crypto at a loss + immediate UNI repurchase: realised loss + maintained position.
Approval mechanics + revocation hygiene. UNI is ERC-20; every new DEX you swap UNI on requires a one-time approval transaction. Use revoke.cash to manage + revoke approvals after use.

Step-by-step

Decide CEX or DEX based on the target asset. UNI → BTC/SOL/USDC cross-chain: CEX is simpler. UNI → ERC-20 token: Uniswap v3/v4 (the recursive case). UNI → stablecoin: 1inch routes for best execution.
If DEX: connect MetaMask + verify Ethereum or L2 network. app.uniswap.org or 1inch.io. Verify URL. Connect wallet, ensure correct network.
Set slippage tolerance + check pool depth. Major pairs (UNI-USDC, UNI-WETH): 0.5% slippage. Long-tail ERC-20s: 1-3%. UNI pool depth is top-tier on Uniswap, so retail-size trades have tight slippage.
Execute the swap + retain transaction details. CEX: 1099-DA reports automatically. Uniswap / 1inch / ParaSwap: capture tx hash, swap date, UNI amount, asset received, USD FMV. Crypto-tax software auto-ingests from wallet address.
Revoke ERC-20 approvals you no longer need. Use revoke.cash. After swap, revoke the UNI-spend approval to limit exposure to compromised contracts.
Decide on holding location for the received asset. Long-term hold: bridge to L1 + self-custody. Active trading: keep on the venue/L2. Yield: deposit into Aave/Compound on the L2 you swapped on.

Tax summary

Swapping UNI for any other asset IS a taxable disposal of the UNI at FMV on swap date. Gain/loss = swap-FMV - cost basis. Asset received establishes a new cost basis. 1099-DA covers CEX swaps 2025+; Ethereum + L2 DEX swaps (Uniswap, 1inch, ParaSwap, OpenOcean) must be self-reported on Form 8949. UNI pool depth on Uniswap is top-tier — DEX routing is competitively priced vs CEX. See /crypto-taxes-us/.
