TODO

• Based on CKB Testnet public RPC - https://testnet.ckb.dev/rpc

  • Problem statement：
    • zero2ckb-server was based on a self-built CKB devnet, which lacks maintenance and has occasional failures
    • failed to keep up with the latest version of CKB in time
    • inconvenient to query the transaction created by developers
  • Tasks:
    • Interact with CKB testnet to make things easier and clearer
    • (optional) guide the new developer how to read transaction on ckb-explorer

• Connect a wallet and use omni_lock to sign transactions in the exercises

  • Problem statement：
    https://zero2ckb.ckbapp.dev/learn#hands-on → 3 wallets were provided.
    But when multiple users practice online at the same time, it is difficult to avoid conflicts.
  • Tasks
    • Use Popular browser wallet extensions such as Metamask or Brave wallet, it may provide a better experience when a developer want to sign transactions
    • Auto Faucet
      When a new developer arrives zero2ckb.ckbapp.dev/learn and connects to a wallet, the server will send 10 * 100 CKB cells to his/her address for later practice

• Refactor UI/UX

  • fix: the current zero2ckb page cost too much CPU
  • Make the error prompts in the exercises more friendly
  • Design check steps components for zero2ckb
  • etc.
