DEX & permissionless markets

What a DEX is (and is not)

A decentralized exchange interface helps you interact with on-chain liquidity — automated market makers (AMMs), on-chain order books, or intent-based routers — while your keys stay in your wallet. The website is usually a frontend. The risk is in smart contracts, approvals, RPC endpoints, and phishing clones.

CryptoDecentral will not embed swap widgets, route trades, or show live prices. We link out. You verify. You sign.

Non-custodial vs CEX (clear contrast)

A centralized exchange (CEX) takes deposits into accounts it controls. You trade IOUs until you withdraw. Counterparty risk, KYC graphs, withdrawal freezes, and insolvency are part of that model — sometimes regulated, sometimes not.

A non-custodial / DEX path means you keep signing keys and the protocol settles according to its rules. You still face smart-contract bugs, UI phishing, MEV, and user error — but the venue is not holding a pooled balance with your name on it. That distinction matters for threat models and for why CryptoDecentral refuses to become a custody or brokerage intermediary.

• CEX: custody + account recovery narratives + compliance surface.
• DEX / P2P non-custodial: local keys + contract or escrow logic you must verify yourself.

Verify the frontend

• Prefer bookmarks you typed yourself over search ads. Typosquat domains are a cottage industry.
• Check HTTPS certificates, official social/Nostr announcements, and — when available — IPFS or self-hosted frontends with known hashes.
• Review token approvals. Unlimited allowances are convenient until a malicious spender drains you.
• Simulate transactions when your wallet supports it. Read the calldata summary before you click confirm.

Longer checklist: Verifying frontends.

AMM vs order book (short)

AMMs price via reserves and invariant formulas; slippage and impermanent loss are the vocabulary. On-chain order books look more familiar to traders but still settle on-chain. Neither design makes you immune to MEV, oracle issues, or governance capture of the protocol.

P2P patterns (education only)

Some tools emphasize peer-to-peer matching with less platform custody — useful as design patterns, not as “go trade here” prompts:

• Bisq — desktop P2P exchange design; security depends on your operational hygiene and understanding of how trades settle.
• RoboSats — Lightning-oriented P2P coordinator pattern; we may show soft activity counts on /metrics (robots / public order counts only — never volume or USD). Not a buy/sell signal.

Naming a pattern is not a recommendation to use it, and not personalized advice.

Link-out examples (informational)

These are well-known starting points for research — not endorsements, and not invitations to trade:

• Uniswap — AMM family documentation and interfaces.
• Curve — stableswap design literature.
• Protocol docs generally — read before you click.
