We will soon conduct a significant upgrade to the JoyID Mainnet contract deployed on the Nervos CKB blockchain. This upgrade will mainly enhance and update the multi-signature lock script to further improve security and functionality.

Key Points:

• The fundamental and core functionalities of the contract will remain unchanged. All existing operations will continue to work as before.

• However, the JoyID cell_dep configuration must be updated to remain compatible with the upgraded contract.

  • The latest JoyID Mainnet contract cell_dep:

  {
    out_point: {
      tx_hash: "0xaac4f0e31adda9ac98e4c446063e2725f9e98a01d1aa94ef34077c7c6a1d6b9f",
      index: "0x0"
    },
    dep_type: "dep_group"
  }
  

• The JoyID Testnet contract has been updated and the latest Testnet cell_dep is here:

// The latest JoyID testnet cell_dep
{
  out_point: {
    tx_hash: "0x759f281588c96979764cb21c196478cf8e13ea81fede7f4ba26d1ff29dbc6a81",
    index: "0x0"
  },
  dep_type: "dep_group"
}

• The CCC SDK has been updated for JoyID Testnet upgrade in https://github.com/ckb-devrel/ccc/pull/252

Actions Required for Teams and Developers:

• After the contract upgrade, please update your JoyID cell_dep configuration immediately.
• If you are using the CCC SDK, ensure you upgrade to the latest version to avoid compatibility issues after the contract upgrade. For upgrade information, see https://github.com/ckb-devrel/ccc/pull/286
• If you are still using the @joyid/ckb SDK along with Lumos to assemble and sign CKB transactions, we strongly recommend migrating to the CCC SDK for better compatibility and ongoing support.

Additional Notes:

• The exact upgrade date will be announced soon, so please stay tuned for updates.
• If you have any questions or need support during the upgrade process, feel free to contact us.

Thank you for your continued support of JoyID!
