In general, Ethereum works on the same principle as Bitcoin and consists of a chain of blocks containing information about the history of all transactions. However, it does differ slightly. The platform has an additional layer, popularly dubbed the Ethereum Virtual Machine (EVM). This layer allows each of us to program a smart contract on the Ethereum platform.

Why did we mention smart contracts? And what do they have to do with ERC 20 tokens? Ethereum Request for Comment, number 20 or ERC-20 for short, is one of the most common standards (set of rules) that developers can use to create tokens that support smart contracts, making them compatible with various products and services. This standard is used to facilitate interoperability between tokens created on the Ethereum platform so that they can be easily created, used and exchanged on the blockchain.

How are ERC-20 Tokens Created

In 2015, German developer Fabian Vogelsteller decided to contribute to the history of Ethereum and left a comment on the project’s Github page. His comment was the 20th in a row, and it was the first time he mentioned ERC-20, which was proposed as a way to solve the network scalability problem as Ethereum continued to grow rapidly.

Fortunately, the development was already approved and implemented 2 years later. Thanks to Fabian, these days smart contracts and tokens on the Ethereum blockchain are compliant with the new ERC-20 standard, and have the ability to interact with other tokens on the network.

What Can ERC-20 Tokens Do

Being fungible, ERC 20 token:

  • Can be used as a medium of exchange;
  • Gives holders a voice in management and creates opportunities for passive interest income through staking rewards;
  • Enables participation in popular applications and activities available on Ethereum. For example, blockchain games or trading non-functional tokens (NFTs);
  • May be used to raise funds for a new project;
  • Can be used for the purpose of creating a loyalty program for a business, or providing access to a particular service or product.

What are the Advantages of ERC-20 Tokens

Optimized token creation process: No need to start your code from scratch or worry that the tokens created will be incompatible with other tokens or dApps on the Ethereum blockchain.

Increased liquidity: Since 2017, token holders have had access to a wide range of decentralized exchanges and trading pairs. But before that, Ethereum users could not always use tokens in all dApps, meaning trading was not as accessible as it is today.

Tokenization: The ERC20 tokens list allows tokenization of various assets such as real estate and products, opening up new opportunities for fractional ownership and efficient value transfer.

Risks and Challenges of ERC-20 Tokens

Unfortunately, the list of ERC 20 tokens has problems such as: lack of regulation, liquidity risks, phishing and fraud. The low barrier to entry means that scammers, for example, can easily create their own fake projects or websites to trick users into sending their tokens to fraudulent addresses. So be careful to avoid such scams.

TOP ERC 20 tokens

Tokens created using the ERC-20 standard can represent many different virtual assets – both digital currencies and tokens based on real assets. Common types of ERC-20 include management tokens, reward tokens, stablecoins, and memcoins. Here’s a list of the best ERC 20 tokens:

  • Ethereum (ETH)
  • Tether (UDST)
  • USD Coin (USDC)
  • Polygon (MATIC)
  • Wrapped Bitcoin (WBTC)
  • DAI (DAI)
  • Uniswap (UNI)

The Future Of ERC-20 Tokens

The future of ERC-20 tokens is dynamic and evolving. Now the developers are making every effort to eliminate the shortcomings of the project and introduce alternative standards for the tokens of the platform. All this in the future is designed to expand functionality, improve security, provide additional features of the ERC-20 standard and create new ERC 20 tokens.

Doctor visit helper

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Rest, drink safe water, and observe symptoms carefully.
  • Keep a written note of symptoms, duration, temperature, medicines already taken, and allergy history.
  • Seek medical care quickly if symptoms are severe, worsening, or unusual for the patient.

OTC medicine safety

  • For mild pain or fever, ask a registered pharmacist or doctor before using common over-the-counter pain/fever medicines.
  • Do not combine multiple pain medicines without advice, especially if you have kidney disease, liver disease, stomach ulcer, asthma, pregnancy, or take blood thinners.
  • Do not give adult medicines to children unless a qualified clinician advises it.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
