How to lock the token about 0x-starter-project HOT 12 CLOSED

@narmadhasugumar to reverse the process set the allowance to 0. You can do this using:

zeroEx.token.setProxyAllowanceAsync(new BigNumber(0));

Or in-case you are using the V2 0x.js library (>= 1.0.1):

contractWrappers.erc20Token.setProxyAllowanceAsync(new BigNumber(0));

from 0x-starter-project.

@fabioberger, This is for locking the token?..
zeroEx.token.setProxyAllowanceAsync(new BigNumber(0));

And if i want to get the unlocked contract tokens and loked contract tokens dynamically how to get that one ?

from 0x-starter-project.

How to get
const zeroEx = new ZeroEx(web3js.currentProvider, { networkId: networkId })
networkid dynamically?
If i am trying to get dynamically it shows error like this

by locking it doesn't sign into metamask for permission?As u suggested i tried but not working i think

@narmadhasugumar I cannot understand your issue fully. Please write in full sentences and try and describe the issue you are facing fully.

As for the networkId issue, make sure the networkId you are passing in is a number, not a string.

First Issue:
I just want to UNLOCK and LOCK the token, here in below image WETH can locked & unlocked, so i am able to UNLOCK the token but unable to LOCK the token, and unable to get the UNLOCKED tokens from. Just want to know how to LOCK and how to get the UNLOCKED list of tokens
.

SECOND ISSUE:
Is we have any possibilities to get the networkId dynamically instead of mentioning the networkid : 1 (statically)

Are you getting my issue @fabioberger

@narmadhasugumar the UI showing "locked" and "unlocked" is a simplification of the reality. In reality, users are setting and unsetting their addresses' allowance to the 0x proxy contract. Locked is when the allowance set is 0, unlocked is when it's set to the largest possible allowance amount 2^256-1.

Setting allowances always requires the user to send a TX to the network.

ok thank you @fabioberger for the explanation you gave for locking and unlocking i will try

below code is for unlock

 await Promise.all(addresses.map(address => {
      return zeroEx.token.setUnlimitedProxyAllowanceAsync(WETH_ADDRESS, address)
 }))

and, for lock
zeroEx.token.setProxyAllowanceAsync(new BigNumber(0))

from 0x-starter-project.

Np. Yes, that is correct but be sure to also await that those transactions are mined (you can use: https://0xproject.com/docs/web3-wrapper#Web3Wrapper-awaitTransactionSuccessAsync).

Good luck!

ok thankyou @fabioberger .

One more think i want to know,

const zeroExConfig: ZeroExConfig = {
       networkId: 50, // testrpc
};

Is this the only way to get networkid directly, we cnt't take dynamically ? I am new to this platform so have so many doubts

Are you getting my issue @fabioberger

how do you know the state of Token ? like WETH is locked , is there a function in 0x.js?

from 0x-starter-project.

Yes, @fpChan it is called Checking the allowance status of the tokens, Here below i mentioned
const allowance = await contractWrappers.erc20Token.getProxyAllowanceAsync(tokenAddress, address)
