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 prices enforced by the contract. The app does not hold private keys or user funds.

Core features

Immutable escrow (v2) — No owner, no upgrades, no pause. Fee recipient, PARA token, and tier thresholds are fixed at deploy.
Listing types
- Standard — Buyer must purchase all remaining tokens in one transaction.
- Crowdfunding — Buyers can purchase any amount at the same per-token rate; a progress bar shows fill status.
- Live market — Partial buys like crowdfunding, but total ETH price can track DexScreener (highest-liquidity pool) on a ~60 second epoch.
Private sales — Sellers can allow only one buyer wallet to purchase (optional).
Market comparison — Listings show whether price is above, below, or near public market data.
Approved tokens — Only tokens with market cap ≥ $300,000 can be listed (you can submit addresses for approval).
Fees — Base 1% of tokens (seller) and 1% of ETH (buyer) per fill; holding PARA can reduce fees to 0.9%, 0.75%, or 0.5%.

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 and live-market listings.
No accounts — your wallet address is your identity.
