Catemask: Setting approval for multiple collections, we emphasize one transaction
While waiting for transactions with Ethereum Blockchain, you know that applying several contracts or Walels Simulty simultus. In Thist art we will explore how to create confirmation of multiplication, we give a transaction through Metamk.
MEMAMAMAMK SERTTANT Function
Metamk Humes Popular Ethereum Wall Thtlalls to send and take ether (th) while improving birthday management. One of the main features of Metamask is the ability to identify multiple contracts in a single transaction using the approval of the COMFRALL function.
What is to confirm multiple? **
Etreum each contract has several approvals that purse cant dog in dogs. For testing as smart multiple confirmation of approval purse mandka, subtle:
- A Max: Confirm the Contract Execution (Read or WRTE) for 1 Hour
- Beif B: Confirm the Contract (Read) 24 Hours
Confirmation of multiple collections in Sille deal
To set confirmation of multiple collections, you can use Metamk’s, which is an example that is appropriate through the function. She is an exam exam to do this:
`Nac
// Determine approval for all contracts for 1 hour
be metamk.setall (
“0x…” “, // Agreement address
{…}, // confirms the object with multiple wallets and lasts
Party // to determine that the contract is anlowed to fulfill the progress of the progress
۳۶۰۰۰۰۰ // ۱ hour seconds
)
s
In the Thest we confirm for 1 hour to all contracts (Sangle object array). We indicate… So there are several approval approvals on the object, each confirmation of the wax is "Wallet", travel and choice imagination.
Main Formats
He is the distribution of the main parameters of the exam:
- SconracToradress ”: Agreement address you want to determine the approval.
- This is a confirmation: there are several approval confirmations of objects. Each object is three right: worn, wet, "which ice speaks, empty and choice.

Insert the use of use
In the Appendix, you are creating a decentralized application (DAPP) T requires a number of applicants for approval of approval approval approval. You can set confirmation to all contracts by ordering one transaction using Metamask:
Nac
// Set confirmation of 1 hour and 24 hours for all wallets
be metamk.setall (
“0x…” “, // Agreement address
{…}, // confirms the object with multiple wallets and lasts
Party // Determine the Agreement is Anlowed to meet on behalf
[۳۶۰۰۰۰۰, ۸۶۴۰۰۰۰۰] // ۱ hour and 24 hours in sensors
)
`s
In this exam, we determine the entire contract (array of objects) for 1 hour (‘360000’ seconds) and 24 hours) and 24 hours (‘8640000’ seconds). “The kit is a parameter indicating that the contract is terrible to execute the words of each wall.
By setting a multi -aircraft process approval in a single transaction, you can improve the management permit and reduce the number of transactions completed by completion of the completion complexes.
