Transcript

this video is proudly brought to you by wwd with lcks our official sponsors for cohort 11 in this video we will be talking about multi [Music] call multi call is process of batching several functions into a particular function to make calls onto the blockchain let's say for example you need to interact with the blockchain like multiple times but then multicol makes it possible for you to make those multiple calls into one particular call and or one particular function it's very useful in um situations where you need to interact with the blockchain multiple times but then you use multi call to make that call once and execute those particular [Music] functions uh one of the reasons why mostly call it is it improves user experience so if you have used uh a decentralized application before you must have seen that you have to send every transaction yourself which is very necessary and important for security and some other reasons but with mul call instead of you having to like sign every single transaction approving everything at once it could be bashed together and a lot of things can be sent at once and then it's approved and then you just have to just approve once for a lot of things to happen it improve the user experience for you and then for for scalability like as as the need for interaction increase on the blockchain it helps in scalability and multile helps for gas optimization so it reduces the number the amount of gas that you pay because for each CH you would have paid different gas for each transaction but now you're just paying one gas for the B transaction you can't actually like overemphasize the importance of multic call we are have three main type of multicore we have the simple multicore you have the dynamic multicore and the batch multicore and um as my colleague has spoken earlier they majorly focus on the batch multicore so basically multi call makes makes it easier to like call a particular function multiple times in our smart contract you know um if like we want to like get some data like at once multi make it easier instead of signing that particular transaction every time calling that particular function multiple times so multiple call batch the transaction all together and then turn the response to once so this would have been possible without um the multicore contract which was found which was founded by m so basically multicore is very very important in in um in writing of smart contract in writing of our adap m is very very very very much important um it makes it easier for a developer and as well the user experience because if we decide to sign a particular transaction multiple times it's an over for the for the user which might like they might lose interest in that particular DB so with multi call we can like batch a particular transaction multiple times [Music]
