What is the ERC20 address?
The ERC-20 standard allows an address to give an allowance to another address to be able to retrieve tokens from it. This getter returns the remaining number of tokens that the spender will be allowed to spend on behalf of owner .
The exchange will make it clear what type of chain they are using; however, one easy way to differentiate between these two is by the way the address is structured. An ERC20 Address only starts with '0' and 'x'. For example: 0xbc6e. A TRC20 Address only begins with a capital 'T'.
Because Ethereum and ERC20 tokens are all stored on the Ethereum blockchain, they are stored at the same address. This Ethereum address always starts with 0x.

A non-ERC20 will return a 'null' 0x hex response whereas an ERC20 will give you a 32byte uint , in this case 0 but if you provide an address in the data then it will give you the actual token balance for that address.
How do I name my ERC20 token?
ERC20 Contract – Name
The name of the token contract is rather straightforward, and it is the long name by which the token contract should be known. For example, let's say the name of our example ERC20 contract would be “Our Example Token”. As far as the length of the name goes, there are no restrictions.
All ERC20 tokens built on the Ethereum network have a wallet address that starts with 0x (zero-x), includes numbers, upper-case and lower-case letters, and are 42 characters long and if you input something other than an ERC-20 token wallet address and transfer your digital assets there, you may lose your assets.
You cannot deposit ERC-20 tokens to your ETH (HEX) deposit addresses on your Kraken account. Each cryptocurrency, including any ERC-20 tokens we list, have their own deposit addresses. You can only deposit ERC-20 tokens that we have listed. All ERC-20 Tokens on Kraken use a shared address.
You can now send and receive ERC20 tokens. Get started by sending your ERC20 tokens to the Ethereum account of your choice. The token accounts will only appear after the token transaction has been confirmed on the Ethereum blockchain.
An example of an Ethereum address is 0xb794f5ea0ba39494ce839613fffba74279579268. Contract addresses are in the same format, however, they are determined by sender and creation transaction nonce.
On Ethereum and other networks compatible with the Ethereum Virtual Machine (EVM), public addresses all share the same format: they begin with 0x, and are followed by 40 alphanumeric characters (numerals and letters), adding up to 42 characters in total.
The ERC-20 token standard defines the decimals() function that your contract implements, effectively shifting all numbers by the declared number of zeros to simulate decimals. So if you wanted to mint 1 token with 18 decimals, you'd need to pass the value 1000000000000000000 (18 zeros).
Open Metamask and click on the Add Token button, select the Custom Token option and paste the contract's address in the first field. Metamask will fetch the Token Symbol and decimals automatically. Click on next and your token will be added to the wallet, it will be available under the assets section in Metamask.
hit ctrl+F or cmd+F and search for ERC. This will probably yield ERC20 and possibly other numbers corresponding to other types of tokens, which usually are a superset of ERC20.
ERC-20 standardizes the core functionality of each token, meaning that all tokens created using this framework are interoperable with each other as well as all ERC-20 compatible services like MyEtherWallet and MetaMask.
Is ERC20 the same as Ethereum?
What's the difference between ETH and ERC20? ETH, or “Ether,” is the native cryptocurrency of the Ethereum network, and is used to facilitate transactions on the Ethereum blockchain. ERC20 is the protocol standard for creating Ethereum-based tokens, which can be utilized and deployed in the Ethereum network.
The cost to move an ERC20 token like USDT or USDC, is about $4.37 per transfer.
One of the best and most popular ERc20 wallets to store ether and other ERc20 tokens on mobile is Enjin wallet. It is available for download at both the Google play store and the App Store.
Note that all Ethereum wallet addresses are ERC20 compatible. Moreover, this means that every ERC20 transfer can happen between two Ethereum wallet addresses, or ERC20-compatible addresses.

Remember that you can renew lifespan anytime. You can own a . eth domain for a year for only 0.012 ETH(~$5) or 10 years for 0.123 ETH(~$50).
A contract cannot change its address. Token contracts are not an exception. In practice, a token author may issue a new contract. In such a case, it is always a migration from the old contract to the new, so you have two contracts - the old token and the new token.
ERC20 tokens require Ethereum (ETH) to pay for transactions on the Ethereum network. You can enable custom fees for ETH and ERC20 tokens.
There are no known issues with sending ETH and ERC-20 tokens to external addresses, as long as the wallet or exchange you are sending your tokens to supports the token you're transferring. If you're not sure if the ERC-20 token is supported by your wallet, please check with its developers first.
How do I do an ERC20 transfer?
To transfer ERC-20 tokens, we'll need to broadcast a transaction to the blockchain just like before, but with a few changed parameters: Instead of setting a value for the broadcasted transaction, we'll need to embed the value of tokens to transfer in the data send in the transaction.
