Let’s dive into decentralized exchanges, what makes them different from their centralized counterparts, and the core concepts you’ll need to grasp before connecting a wallet or making trades.

A decentralized exchange, or DEX, doesn’t belong to a specific company. You’re in complete control of your funds, this means you triple-check details yourself, because there’s no help desk to fix mistakes.
Decentralized exchanges let you trade directly from your own hot or cold wallet using smart contracts. More on these in the next step.
Think of smart contracts as a vending machine: when you select a snack and pay, the machine automatically dispenses it. Similarly, smart contracts are lines of code that execute transactions once their conditions have been met.
DEX transactions are “onchain”, meaning they happen on the blockchain — recorded in real time for everyone to see.
You’ll need to pay two small fees on a DEX for your transaction to go through. The first is called a gas fee. The busier the network, the higher the fee. The second fee is called a swap fee and is a percentage of the transaction you’re wanting to make.
Gas fees go up when the network is busy because transactions compete to be processed. Those offering higher fees are prioritized, so when demand increases, you may pay more to have your transaction confirmed faster.
Gas fees are paid using the network’s native token, such as ETH on Ethereum or SOL on Solana. Make sure your wallet holds enough of this token before making a swap.
Swap fees work differently. They are usually deducted from the amount you are trading and are paid to liquidity providers, who deposit tokens into shared pools so others can trade. In return, they earn a small share of each swap fee.
Start by picking a well-known decentralized exchange on the network you plan to use. Each DEX operates on specific networks and only works with tokens built for them. Look for clear fees, simple design, active community help, and recent security notes or audits.
You’ll hear “network” and “chain” used interchangeably. In most cases, they mean the same thing, such as Ethereum, Solana, or Bitcoin.
A blockchain network is the system that processes and records transactions. Each network has its own rules, supported tokens, and transaction fees.
Before sending or swapping crypto, make sure your wallet and the platform are using the same network. Sending tokens on the wrong network can cause the transaction to fail or make your funds difficult to recover.
Make sure the DEX supports the crypto and network you’ll use. If it does, save the DEX's URL as a bookmark so you can come back to it later and avoid visiting a lookalike page that could be a scam.
Decentralized exchanges give you more freedom and flexibility than their centralized counterparts, but they also require more know-how. You’re responsible for your own trades, fees, and security — there’s no support team to fix errors.
Pressure? Slow down.
Ask someone you trust.
Use official channels to verify.
Sending money? Stop.
Experience matters. Share and report it.
Taking a few extra minutes to PAUSE could prevent a permanent loss.
Scammers rely on speed, pressure, and confusion. They want you to react before you have time to think, verify, or speak to someone you trust.
When something feels urgent, unusual, or too good to be true, take a moment and PAUSE.
This simple five-step framework can help you recognize a potential scam, check whether a request is legitimate, and protect yourself and others before any money or information is lost.
If someone is pushing you to act immediately, slow down.
Scammers often create a false sense of urgency. They may tell you that your account is at risk, that you owe money, that an opportunity is about to disappear, or that something bad will happen unless you act now.
A legitimate organization will give you time to understand what is happening, ask questions, and verify the request.
Pause if you are being told to:
Urgency is one of a scammer’s most reliable tools. You do not need to act on someone else’s timeline.
Before you send money, click a link, download an app, share a password, or provide personal information, speak to someone you trust.
This could be a family member, friend, colleague, caregiver, or someone at your bank.
Scammers often try to isolate people. They may tell you that the situation is confidential, that nobody else will understand, or that speaking to someone could cause you to lose an opportunity.
Those are warning signs.
A second person can help you notice something you may have missed, ask useful questions, or confirm that the request does not make sense.
One conversation can be enough to stop a scam.
Never verify a request using the contact details provided by the person who contacted you.
Instead, end the conversation and independently find the organization’s official contact information.
To verify a request:
Do not click links, call phone numbers, or use email addresses sent to you by the person making the request. Scam websites and phone numbers can look convincing.
If the request is legitimate, the organization will be able to confirm it through its official channels.
Stop immediately if someone asks you to make a payment using an unusual, irreversible, or difficult-to-trace method.
No bank, government agency, police department, technology company, or legitimate business will require you to pay through:
Scammers prefer these payment methods because the money is often difficult or impossible to recover.
They may stay on the phone while you make the payment, give you step-by-step instructions, or tell you what to say if a bank employee asks questions.
That behavior is not normal. It is a major warning sign.
Do not send the money. End the conversation and contact your bank or the relevant organization directly.
A scam attempt is worth talking about, even if no money was lost.
Sharing what happened can help protect your friends, family, colleagues, and community. It can also help organizations identify patterns and prevent the same scam from reaching someone else.
If you lost money or shared sensitive information, report it as soon as possible. Contact your bank, the affected platform, and the appropriate fraud-reporting service.
There is no reason to feel embarrassed. Scammers use sophisticated tactics designed to create fear, trust, excitement, and confusion. Anyone can be targeted.
A close call is worth sharing. A loss is worth reporting.
You are not alone, and speaking up may protect the next person.
