Uniswap on Testnet

Open nitika-goel opened this issue 6 years ago • 10 comments

Hi, Great work @Uniswap! Tried writing a mail but did not get a response there. Hence, trying to reach out here.

We are interested in integrating Uniswap for our project Nexus Mutual. Just 2 quick questions here:

  1. Which testnet are you guys on?
  2. We are interested in an exchange between ETH and DAI and vice versa. What is the best way to implement this?

Hi Nitika,

To answer your questions:

  1. The front end app can be run on Rinkeby. But you can also redeploy the contracts using Ganache or other testnet tools too.

I have tested both swaps and liquidity functions using Rinkeby. Just fork https://github.com/Uniswap/uniswap-frontend and run it with yarn start:rinkeby.

  1. Calling the createExchange method from the Factory contract.

@rossbulat , can you provide more detail on how to compile and deploy the contracts to ganache?

@WyseNynja my testnet deploy steps were:

  1. Install uniswap as specified in the README. Make sure to switch to the Vyper compiler version specified.
  2. use vyper uniswap_factory.vy to get bytecode and vyper -f abi uniswap_factory.vy to get the ABI. Do the same for uniswap_exchange.vy
  3. Deploy both contracts separately from their bytecode using https://mycrypto.com/contracts/deploy
  4. Use factory ABI (step 2) + factory address (step 3) and https://mycrypto.com/contracts/interact to open an interface to the uniswap factory
  5. call initializeFactory(templateAddress) and pass in the address of the deployed uniswap_exchange.vy contract (step 2)

Hello, in step 5, when i choose initializeFactory(templateAddress) and paste exchange deploy address, and about Value, what i should input in Value??

@haydenadams i don't understand which address in step 4 and step 5, 4.Use factory ABI (step 2) + factory address (step 3) and https://mycrypto.com/contracts/interact to open an interface to the uniswap factory ==> [factory address] means the [factory contract address] or [factory address] use to deploy contract? 5.call initializeFactory(templateAddress) and pass in the address of the deployed uniswap_exchange.vy contract (step 2) ==>what is [address of the deployed]? the [exchange contract address] or [exchange address]?

@bboynam99

  1. factory contract address
  2. exchange contract address

@haydenadams i will replace with my contracts here in addesses.js right?

const MAIN = { factoryAddress: '0xc0a47dFe034B400B47bDaD5FecDa2621de6c4d95', exchangeAddresses: { addresses: [ ['BNB', '0x255e60c9d597dCAA66006A904eD36424F7B26286'], ['DAI', '0x09cabEC1eAd1c0Ba254B09efb3EE13841712bE14'], ['KNC', '0x49c4f9bc14884f6210F28342ceD592A633801a8b'], ...

if it is, i wondering why so many exchange contract addresses for each tokens like that? is it ok if i use same 1 exchange contract address for those tokens??

This is the script to setup uniswap on testnet. :)
