Step 2: How to get USDC & USDT on Astar Network

To purchase TBIO, you must have USDC or USDT on Astar Network. To do so, you can either transfer stablecoins from another EVM blockchain or swap ASTR tokens on a DEX.
USDC: 0x6a2d262D56735DbA19Dd70682B39F6bE9a931D98 USDT: 0x3795C36e7D12A8c252A20C5a7B455f7c57b60283
  • How to bridge
You can transfer USDC or USDT from EVM blockchains such as Ethereum, Polygon, BSC using bridges like cBridges or Anyswap.
Please visit cBridge, connect your Metamask, chose the network, and then input the amount of USDC or USDT you would like to transfer.
  • How to swap
First, you must have ASTR tokens on Astar EVM,. Astar Network is a blockchain supporting two environments: the native environment WASM and the Ethereum environment EVM. The Astar portal allows transferring your token from one environment to another and vice versa.
To send ASTR tokens from a CEX to your native Astar environment, connect your polkadot.js wallet to the Astar portal and copy your native address. Go to your CEX and withdraw your ASTR tokens to the native address using the Astar Network.
Once you have your ASTR tokens on your native address, you can send them to your EVM address (Metamask) using the portal.
Copy your address from Metamask and past it in the "transfer" box.
To swap your ASTR to USDC or USDT, you can use the native DEX of Astar : Arthswap
  1. 1.
    Go back to and connect your Metamask wallet.
  2. 2.
    Select swap ASTR to wASTR and enter the amount you want.
  3. 3.
    Execute the swap and sign the transaction.
  4. 4.
    Now that you have wASTR, you can swap it to USDC or USDT
  5. 5.
    Enter the amount you want, execute the swap and sign the transaction.
  6. 6.
    You now have USDC or USDT tokens in your wallet.
