Introduction to Shibuya Testnet

Dusty is a standalone chain while Shibuya is the Shiden’s parachain testnet with EVM functionalities which is the closest to the Shiden mainnet. Shibuya has the same chain specifications as Shiden and creates the best test environment for developers who want to launch their DApp on Shiden mainnet.

Launching a stress-test campaign on Shibuya

To contribute as much as we can to the Astar Network ecosystem and improve PolkaEx’s product experience, we are partnering with Shiden Network to launch a stress test campaign on Shibuya Testnet!! We strive to be the 1st DApp on the Shiden Network. You can access the Testnet DApp at

The full details and instructions for the campaign are below:

DATE: Use the PolkaEx Dapp on Shibuya Testnet between September 11th — September 15th UTC. This campaign will last for 5 days.

Campaign details


110 testers out of all testers who use the Dapp, provide great and valuable feedback will win SDN as stated below:

🔹 10 winners will be rewarded 50 SDN each;
🔹 The remaining 100 winners will be rewarded with 10 SDN each;
🔹 1 SDN ≈ 5 USDT.

Steps of Participation

Step 1: The following basic tasks need to be completed:

  1. Click this link: Twitter links.
  2. Retweet, Like, and tag 3 friends.
  3. Follow @PolkaExOfficial and @ShidenNetwork.
  4. Join the official PolkaEx Telegram Group and Astar Network Telegram Group.

Step 2: Access the DApp deployed by PolkaEx on Shibuya(Closest to Shiden Network)

Enter the DApp, select the Shibuya network, and follow the prompts to add the Shibuya network to Metamask(Or you can set up the Shibuya network directly in Metamask). The Shibuya network requires a low service fee. Therefore, users participating in the campaign need to get SBY tokens through the faucet, and for convenience, we have specially developed a claim page:

Select ‘Shibuya’

Step 3:Get SBY tokens on Shibuya

  1. Enter the faucet, input your ERC-20 address and click the “REQUEST 1 SBY” button to get 1 SBY token.
  2. After a successful claim, you need to make sure your Metamask has been switched to Shibuya in order to see the SBY tokens. Follow this procedure, go to Settings -> Networks ->Shibuya inside the “New RPC URL” modified into:

🔹 Network Name: SHIBUYA
🔹 Chain ID: 81
🔹 Currency Symbol: SBY

Modified the “New RPC URL”

Step 4: Important Reminder

Add the 4 contract addresses to your MetaMask in order to view your assets. Below is the Shibuya Network Test Contract address:

🔹 test USDC contact address: 0xA4F42578c723A5B6781A9F49d586B8645ba85C31
🔹 test PKEX contact address: 0x1953250883DDC5ba9946d02AdE3cCb1c4FF12143
🔹 USDC/PKEX LP contact address: 0x878f2bD833E2986FAafe5eb3216CF34bDa51849B
🔹 USDC/SBY LP contact address: 0xFD5492Ad94a62ed095BeAaf800FC070e41A5Fd2e

Here is a method to quickly add PKEX to Metamask:
