Trading guide

Before you start

1. Connect a wallet on Base Mainnet (MetaMask, Coinbase Wallet, Rainbow, etc.).
2. Hold enough ETH on Base for gas and, if buying, the purchase amount.
3. For selling, the token must be on the Approved Tokens page (≥ $300K market cap).

Listing types

Standard

• One buyer takes all remaining tokens in a single transaction.
• Best for fixed-size OTC deals.

Crowdfunding

• Multiple buyers can fill any portion at the same per-token price.
• The listing shows a funding progress bar.
• The seller can cancel anytime and receives only unsold tokens back.

Live market

• Same partial-buy behavior as crowdfunding.
• Total listing ETH price can update about every 60 seconds to follow the highest-liquidity DexScreener pool on Base.
• Buyers confirm a maximum ETH in the wallet; if the live price moves up before your transaction lands, the contract reverts instead of overcharging.
• Best when you want your ask to stay near live market without manually repricing.

Private listings

• When creating a listing, you may paste a buyer wallet address.
• Only that wallet can buy — everyone else can see the listing but their purchase will fail on-chain.
• Leave the field empty for a public listing (anyone can buy).

Selling tokens

1. Go to Create Listing.
2. Choose Standard, Crowdfunding, or Live market.
3. Select a token from your wallet or paste an approved contract address.
4. Amount — choose a percentage of your balance or enter an amount manually.
5. Price — choose a preset vs market, a custom offset, or enter total ETH manually. Live market requires a DexScreener ETH price for the initial deposit.
6. Buyer restriction (optional) — paste a wallet address to make the sale private.
7. Approve the escrow to use your tokens (wallet prompt).
8. Confirm the listing deposit (wallet prompt).

Tokens move into the escrow contract. You can cancel from My Listings until they are sold.

Buying tokens

Standard listing

1. Open the listing on the marketplace.
2. Review the price compared to market and the total ETH required.
3. Confirm the purchase in your wallet.

Crowdfunding or live market

1. Open the listing.
2. Enter how many tokens you want (or use the maximum available).
3. Confirm the ETH amount shown in your wallet (includes a small max-cost buffer on live-market listings).
4. Partial buys reduce the amount remaining on the listing for others.

Private listings

If the listing shows Private, only the designated wallet can buy. Connect that wallet to proceed.

Fees (each purchase)

Base fee is 1% of tokens (seller side) and 1% of ETH (buyer side). Holding PARA at the time of the transaction can lower fees:

Example at base fee: buying 1,000 tokens for 1 ETH — you pay 1 ETH; the seller receives less ETH after the buyer-side fee; the fee recipient also receives a portion of the tokens sold.

Cancelling a listing

Only the seller can cancel an active listing:

1. Go to My Listings.
2. Cancel the listing.
3. Unsold tokens return to your wallet.

Already-sold portions in crowdfunding or live-market listings cannot be reversed on-chain.

Upgrading from v1 listings

If you created a listing on the older escrow contract, it remains on that contract until filled or cancelled. Cancel to withdraw unsold tokens, then create a new listing on the current marketplace (v2). See Security for both contract addresses.

Approving a new token

1. Go to Approved Tokens.
2. Paste a Base ERC-20 contract address.
3. Submit — Paragon checks public market cap data.
4. If the token meets the minimum, it is added to the list for everyone.

Price badges

Prices refresh about every 60 seconds.

Tips

• Always verify the token contract address on Basescan before trading.
• Read the Security page and verify the escrow on Basescan for large trades.
• On live market listings, re-check the ETH total if the price refresh countdown just reset.
• Never share your private key or seed phrase.
