A large number of popular tokens, such as the stablecoin tether and leading oracle service Chainlink, are actually ERC-20 tokens under the hood. The “balanceOf” function finds extensive utility across DApps and token-based protocols. For example, wallets and portfolio trackers utilize the “balanceOf” function to give users insights into their token holdings and overall account balances. Before the ERC-20 standard was introduced, there was no common language for developers to use when creating tokens on Ethereum. This meant that they needed to build projects from the ground up, as well as custom blockchain bridges to exchange any token — both of which required technical knowledge.

Essentially, DONs can use various real-world data (e.g., weather reports or article prices) to create hybrid smart contracts. Wrapped BTC represents a tokenized version of Bitcoin made to conform to the ERC-20 standards. This cryptocurrency was created to bring the immense value of Bitcoin to the programmable Ethereum network. That way, holders can use their BTC for activities such as staking and lending, which are impossible on its native blockchain. The TRON network aims to be a faster and more scalable version of the Ethereum network.
It is widely considered to be a catalyst for the huge surge in dApps and Ethereum-based crypto tokens in 2017 and the growth of (DeFi). Market data from June 2020 found that 47 of the top 100 crypto tokens by market capitalization were built using the ERC-20 standard. ERC20 tokens are a specific type of cryptocurrency token that exists on the Ethereum blockchain.

Use OmniBridge to send LINK from Ethereum Mainnet to Gnosis Chain. You can use the Blast Bridge to transfer ETH from Ethereum Mainnet to Blast Mainnet. You can use the BASE Bridge to transfer ETH from Ethereum Mainnet to BASE Mainnet. To transfer LINK from Ethereum to Base, use Transporter or XSwap Bridge. Use the Avalanche Bridge to transfer LINK from Ethereum Mainnet to Avalanche. The UnlimitedERC20 token removes all supply restrictions, allowing infinite token issuance.
This is the case when your tokens actually represent an off blockchain asset (like gold certificates or government currencies) and you want the virtual inventory to reflect the real one. This might also be the case when the currency holders expect some control of the price of the token, and want to issue or remove tokens from circulation. In the other hand, ‘throw’ will cancel all contract execution, revert any changes that transaction could have made and the sender will lose all Ether he sent Crypto Bull Run for gas. But since the Wallet can detect that a contract will throw, it always shows an alert, therefore preventing any Ether to be spent at all. The constructor is a special startup function that runs only once and once only when the contract is first uploaded to the network. This function will set the balance of msg.sender, the user which deployed the contract, with a balance of 21 million.
Stablecoins (tokens pegged to fiat currencies) often use the ERC-20 token standard. The transaction to the BUSD contract that we referenced earlier is one example, and most major stablecoins are also available in this format. On the other hand, name, symbol, and decimal don’t need to be included, but they can make your ERC-20 contract a bit prettier.

- In order to send tokens, just go to the Send tab and select an account that contains tokens.
- Collectively they help power the network, incentivize miners, and allow others to build their own tokens on top of Ethereum’s blockchain.
- DEXs generally offer greater privacy than centralized exchanges, as they do not require users to provide personal information or go through a verification process.
- Chainalysis supports ERC-20 tokens across its compliance and investigation product suite, including Chainalysis KYT and Chainalysis Reactor.
To make your token tradable, you will need to add liquidity on a DEX such as Uniswap or Pancaswap. Once the liquidity is added, anyone will be able to buy and sell your token instantly. Create an account and start accepting payments – no contracts or KYC required. ICOs, or token sales, are events where investors acquire tokens in return for funding a project in the hope that the project will be successful, the token will increase in value and/or yield returns.
