hey there, im trying to interact with a "write" function of my deployed smart contract from a specific account

What is the syntax? I am trying to use:

mycontract.myfunction.sendTransaction(params..., {from: myaccount });

Is that correct?

... doesnt work haha

do u have any resource/doc where I can check it?
I tried a lot of forms... and I didnt get it

It should looks like this mycontract.methods.myfuncion().send({from: accounts[0], gas: '100000'})

Does anybody know what is this repo https://github.com/MyEtherWallet/MyEtherWallet. I thought it repo of myetherwallet.com, but it is not. Repo for myetherwallet.com is https://github.com/kvhnuke/etherwallet. I build sources from this repo, and it looks very differently from the site.

I received answer "This is the version 5 of MEW and other repo is the current version, version 5 is still under development".

what about the params?

mycontract.methods.myfuncion(param1, param2).send({from: accounts[0], gas: '100000'})

thanks, I will try it!

If function is read only, and marked as "public view" it could be excecuted with .call(). mycontract.methods.myfuncion(param1, param2).call() No gas or account required.

I have already done it! Thanks anywayn

If a view function is called internally from another function in the same contract that is not a view function, it will still cost gas. This is because the other function creates a transaction on Ethereum, and will still need to be verified from every node. So view functions are only free when they're called externally.
