1 inch integration

ivan · May 30, 2021, 9:00pm

The best way is to ask 1inch team as this is more their field

ivan · May 30, 2021, 9:08pm

I haven’t tried this but seems like you can get approval tx I’m 1inch api and just ask web3 to execute it https://docs.1inch.io/api/approve

ivan · May 30, 2021, 9:11pm

And when you’ve broadcasted that approve tx you can monitor when it’s done using web3 like this https://ethereum.stackexchange.com/questions/67232/how-to-wait-until-transaction-is-confirmed-web3-js/67234

And then save to DB which tokens user approved when approve tx is confirmed

I think you should have enough info to solve this problem

Let me know how it goes

legenuspl · May 31, 2021, 1:00pm

I tried to contact them but they don’t respond

legenuspl · May 31, 2021, 1:10pm

This is exactly what I did, and afterwards my website (localhost) receive permission to spend tokens on behalf of user

ivan · May 31, 2021, 1:32pm

It’s not your website it’s 1inch smart contract, websites are not a thing onchain even if it says “local host” it’s their smart contract, your site is asking the user to sign that approval so that’s why it says “localhost”

legenuspl · May 31, 2021, 2:31pm

This is exactly what i’m trying Ivan to confirm If there is any contact to 1inch team please let me know

ivan · May 31, 2021, 9:40pm

Try signing the tx and see what happens on chain you will see that their contract got approval to spend your funds

legenuspl · June 1, 2021, 4:25pm

I checked in Ganache, that DAI appeared in MM and with tx of approval, data is:

0x095ea7b300000000000000000000000011111112542d85b3ef69ae05771c2dccff4faa260000000000000000000000000000000000000000000000000de0b6b3a7640000

TO CONTRACT ADDRESS

0x8b0E42F366bA502d787BB134478aDfAE966C8798 LABS

so in data there is 1inch v3 address 0x11111112542d85b3ef69ae05771c2dccff4faa26 so it should work, just sending it on mainnet would be real approval, thx v much for help and time

exactly same spender 1inch v3 address

ivan · June 1, 2021, 9:09pm

peerfect! glad it worked out

legenuspl · June 4, 2021, 9:04pm

can u help me check if my data for swapping tx which im getting from 1inch is longer than this one from 1inch when i use their site directly, is it ok?

mine data received from 1inch API:

can u help me Ivan get help from 1inch? As u see theirs data is way shorter and in mine there are some repetitions but addresses are the same in hex code

ivan · June 5, 2021, 9:18am

Hey this is too much out of scope for us, we can help with Moralis but can’t dive deep and debug what third party APIs do

legenuspl · June 7, 2021, 7:41pm

I understand, but maybe you have some connections with 1inch?

ivan · June 7, 2021, 8:45pm

Unfortunately we don’t have anyone from their team that can check this atm - have you tried writing in their community chat?

legenuspl · June 9, 2021, 7:51pm

yeah, no answer, pretty dead forum

ivan · June 9, 2021, 8:44pm

okok

if you ignore the size of the data
does the transaction generated by 1inch work?

legenuspl · June 10, 2021, 3:30pm

yes! btw, all servers on Moralis stopped working, i see none on my server list (all data is gone)

ivan · June 10, 2021, 3:43pm

ok great, probably because of beta cleanup - we have messaged via email and discord for several days that we will remove all instances with version less than 0.0.224.

legenuspl · June 10, 2021, 6:51pm

ok, i had 223 i guess
