How to Trade PolySwarm (NCT) on a DEX — Beginner's Guide 2026

Create and fund a Web3 wallet

Download MetaMask or Trust Wallet from their official app store. MetaMask supports Ethereum and most EVM chains where PolySwarm (NCT) trades.

Create a new wallet and save your 12-word recovery phrase offline — never screenshot it. Send ETH or USDC to your wallet address. You'll need ETH for gas fees: Etherscan data puts the average Ethereum gas fee at $2-5 per swap, though it spikes during congestion. Buy at least $50-100 worth of ETH so you have enough left over after gas.

Connect your wallet to a decentralized exchange

Go to Uniswap (app.uniswap.org). It has the most liquidity for NCT of any DEX.

Click "Connect Wallet" in the top right corner, then select MetaMask or your wallet provider and approve the connection. If Uniswap shows "Wrong network," your wallet isn't on Ethereum mainnet — open the network dropdown and switch it.

We recommend Bitget — copy-trade top traders & earn up to $6,200 in welcome bonuses. It's a top exchange with strong liquidity and competitive fees.

Select the PolySwarm (NCT) trading pair

Click the "Select token" box on the bottom field and paste the NCT contract address: 0x9e46...d733d1. Verify this address on CoinMarketCap or Etherscan before trading, or just type "NCT" and pick it from the list. Set the top field to the token you're selling — ETH or USDC. Uniswap will estimate how much NCT you'll receive. As of August 2026, NCT trades around $0.0045-0.0058 per token with an $11M market cap, per CoinMarketCap.

Click the settings gear icon on Uniswap and set slippage tolerance to 0.5% for normal conditions, or 1-2% if the market is volatile. NCT moved 5.73% in the past 24 hours as of August 2026, so tight slippage can cause the swap to fail during fast moves.

Set slippage tolerance and confirm the swap

Click "Swap," then confirm in your wallet. Check the estimated gas fee and total cost before approving. Look at the "Minimum received" figure — that's what protects you if the price shifts mid-transaction.

The transaction usually confirms on Ethereum within 15-60 seconds. Track it on Etherscan with the transaction ID from your wallet. Once it confirms, your NCT balance shows up in Uniswap.

Verify the transaction and add NCT to your wallet

To see NCT in MetaMask, click "Import tokens" and paste the contract address again — your wallet fills in the symbol and decimals automatically. Double-check the contract matches the official one before you trust the balance. NCT's circulating supply is 1.88 billion tokens, and 24-hour trading volume across all markets sits near $445,000, per CoinMarketCap as of August 26, 2026. If your balance doesn't show after 5 minutes, check the transaction status on Etherscan.
