Overview
What is Paragon?
Paragon is a non-custodial OTC desk on Base Mainnet. Sellers lock tokens in an on-chain escrow; buyers pay ETH to receive tokens at a price fixed when the listing is created. The app does not hold private keys or user funds.
Core features
- Immutable escrow — No owner, no upgrades, no pause. Fee recipient is set once at deploy.
- Two listing types
- Standard — Buyer must purchase all remaining tokens in one transaction.
- Crowdfunding — Buyers can purchase any amount at the same per-token rate; progress bar shows fill status.
- Market comparison — Listings show whether price is above, below, or near DexScreener/CoinGecko market data.
- Approved tokens — Only tokens with verified market cap ≥ $300,000 can be listed (community can submit addresses for approval).
- Fees — 1% of tokens from seller and 1% of ETH from buyer on each fill (hard-coded in the contract).
Where is my trade recorded?
- Listings and purchases live on the Base blockchain in the escrow contract — permanent and public on Basescan.
- Approved token list is maintained by Paragon so only eligible tokens can be listed.
- Live prices refresh about every 60 seconds for comparison only — always verify before you trade.
- No accounts — your wallet address is your identity.
