Introducing PEX exchange demo — A port of Uniswap on PolkaFoundry testnet
Dear PolkaFoundry community,
We are excited to present you with the Uniswap version on PolkaFoundry tesnet — PEX exchange is now available for public participation.
After a few months of development, we are confident that PolkaFoundry testnet is well-functional enough to host complicated dApps like Uniswap and successfully connect to Metamask, the most popular crypto accessing gateway.
With PolkaFoundry being 100% compatible with Ethereum, dApp developers are entitled to reproduce/port a dApp like Uniswap from Ethereum to PolkaFoundry without modification. Apart from a required slight config, it does not take much effort to switch to the PolkaFoundry network and receive more benefits from our ecosystem.
This Uniswap-based exchange demo is a piece of clear evidence to prove that the DEX projects on PolkaFoundry can truly take advantage of what we offer. Moreover, giving developers our promise to equip them with the complete set of PolkaFoundry’s DeFi UX-enabling features and other services, we provide enough room for creativity and innovation and facilitate projects to add unique features to their products. PolkaFoundry team is currently in discussions with several partners to build highly innovative DEXs on our platform.
We would like to invite you to give it a go on our DEX on testnet mode — PEX exchange and tell us your experience/feedback. Please kindly note, PEX exchange is for demonstration and testing purposes only.
Below are the instructions:
Step 1: Add PolkaFoundry Testnet to your Metamask wallet
Login your Metamask address -> Click to “Ethereum Mainnet” Network -> Choose “Custom RPC”
- Network Name: PolkaFoundry
- New RPC URL: https://halongbay.polkafoundry.com/
- Chain ID: 13
And Save!
Step 2: Add PKF token into the Asset tab on Metamask to show your PKF balance
Go to Asset -> Add token -> Custom token
- Token contract address: 0xDFEA8Ae8228d89e6a2480f5D24C4100171CfD34e
- Token symbol: PKF
- Decimals: 18
Step 3: Claim ETH Testnet Tokens: go to PolkaFoundry Faucet bot on Telegram
Use commands: /help and follow its instructions.
You are supposed to see a command: /faucet to_address — insert your address after /faucet. For example:
You are allowed to claim 1 ETH testnet token per day.
Step 4: Go to https://pex.polkafoundry.com/. Go to the “PolkaFoundry” network on Metamask. You are supposed to see your ETH testnet balance.
Step 5: Swap tokens and add liquidity as your wish on the Uniswap PolkaFoundry-based version.
With 1 ETH you claim, you can swap ETH for PKF.
Then use both funds (ETH & PKF) to go to Pool and add liquidity.
Thank you for your participation! Let us know your thoughts and/or feedback while using PEX on our forum.
How PEX exchange was built: We grabbed the Uniswap source code from Github, changed some configuration, and deployed it to our platform. And it works beautifully. Refer here for PEX’s source code: https://github.com/polkafoundry/pex.
