Metamask: The approval configuration of multiple collections in one event
When you send events in the Ethereum block chain, you may have to accept multiple contracts or wallets at the same time. In this article, we explore how to create approval for several collections in one event with the help of metamas.
Understand the function of Metamskin SetapprovalForALLOLALALALE

Metamask is a popular Ethereum wallet that allows users to send and receive ether (ETH) by allowing advanced access rights. One of the most important features of metamas is its ability to create a number of contracts in one event using the function of the 'SetapprovalForll' application.
What does accepting multiple collections mean?
Each agreement in Ethereum has several approvals that determine which wallets can vote for their state changes. For example, an intelligent agreement may have many different wallet approvals, such as:
- Wallet A: Accept the implementation of the contract (read or type) for 1 hour
- Wallet B: Accept the agreement (read) enforcement for 24 hours
Multiple collections of approval configuration in one event
To determine the approval of multiple collections, you can use Metamask's SetappppProvalfolar '. Here is an example of how it is done:
Sol
// confirms the approval of all contracts for 1 hour
Metamsk.tapprovalforall (
"0x ...", // contract address
{...}, // accept an object with several wallets and duration
True, // The most summerly true if the agreement can be implemented on behalf of the wallet
3600000 // 1 hour in seconds
)
In this example, we will create approval of all contracts (one object) for 1 hour. We define…as an object that contains several approvals in which each approval is an object with 'wallet',duration ‘and optional’ tariff ‘.
Key parameters
Here is the specification of the key parameters used in the example:
Contractionaddress: A contract address that wants to create approval.
- ‘Accepting each object has three features:’ wallet ‘, which is the direction of wallet,’ duration ‘and’ tariff ‘.
- “Set Trime” indicates whether the agreement can be implemented on behalf of the specified wallet.
Example of use
Suppose you are creating a decentralized application (DAPP) that requires multiple approvals for each user account. To create approval of all contracts in one event using Metamsk:
`Sol
// confirms approval for 1 hour and 24 hours for all wallets
Metamsk.tapprovalforall (
"0x ...", // contract address
{...}, // accept an object with several wallets and duration
True, // Summer Shuttive if the agreement can be implemented on behalf of the wallet
[3600000, 86400000] // 1 hour and 24 hours in seconds
)
In this example, we create approval of all contracts (one -one matrix) for 1 hour (3600,000 seconds) and 24 hours (` 86400000 ‘seconds). The “Set True” parameter shows that the contract can be implemented on behalf of each wallet.
By designing the approval of multiple collections at one event, you can optimize access to access and reduce the number of transactions needed to complete contracts.
