How to query and transfer the currency in the contract address on the blockchain?

Speaking of the concept of blockchain smart contract, everyone should be familiar with it. It is a special protocol designed to provide, verify and execute contracts. Smart contracts are blockchains and are called "decentralized" "important reason", and the contract address is a smart contract that maps the account address and balance. In many cases, the contract address plays a very important role. Through the contract address, you can interact with the contract account, and you can also view the detailed contract content. Can coins be transferred out through the blockchain contract address? Generally speaking, you cannot transfer coins directly. Next, I will explain it in detail.

Can the blockchain contract address transfer coins?

The blockchain contract address cannot be transferred directly and needs to be operated through other platforms. A smart contract consists of an address and corresponding storage code. When conducting an ERC20 airdrop on Ethereum, an airdrop smart contract is actually created, and the code of this contract determines the content of the airdrop in the address. Smart contracts do not have private keys. Once transferred to the contract address, it may not be possible to transfer it out again. Therefore, it is not recommended to transfer funds directly to the contract address.

The smart contract address itself does not directly support the transfer of digital currency. Instead, the code in a smart contract specifies the conditions under which funds can be transferred. These conditions may include specific times, specific event triggers, or meeting specific conditions. Only when these conditions are met, the contract will perform the corresponding operations, including transferring digital currency. To implement a blockchain contract address transfer, the following three steps are generally required:

In a smart contract, a transfer function is usually defined to perform the transfer operation. This function may contain necessary logic, such as validating transfer conditions and checking permissions.

Send transaction: The user calls the transfer function in the smart contract by sending a transaction. This can be done through wallet applications, trading platforms, or other blockchain tools. When sending a transaction, you need to specify parameters such as the contract address, transfer function, target address, and transfer amount.

Nodes of the blockchain network verify transactions to ensure compliance with smart contract rules. After verification, the transaction is added to a new block and eventually included in the blockchain.

How to check the blockchain contract address?

There are two ways to query the contract address of a currency: use the blockchain browser or the official website to query. The following is a tutorial on querying the UNI token contract address through a blockchain browser.

1. Open the Etherscan blockchain browser, enter the full name of the token you want to query in the box in the upper left corner and click the magnifying glass to query

2. If you don’t know which public chain the currency belongs to, you can identify it according to the public chain information in the currency introduction. For example, if the public chain to which UNI currency belongs is Ethereum or BscScan, you can query it through these two blockchain browsers at the same time. The token contract address information of the currency

3. Let’s take the relatively popular Uniswap exchange platform currency UNI as an example. After entering the information details page of the UNI currency, You can see that the contract address is: 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984
