• Added Methods:

  • Method for querying USDT Balance

    • getErc20TokenBalanceWithDepositedBalance()

  • Signing smart contract for USDT transfer

    • For USDT transfers implemented via smart contract including Swap, Developers must include depositTokenAddress and depositAmount in the kaia_sendTransaction request.

    • Changes are required when the walletType is WEB or LIFF. If the walletType is not a WEB or LIFF, developers should use the AS-IS parameters.

      • for WalletType is not WEB or LIFF (AS-IS)

      params = {
      type: "SmartContractExecution",
      from: "0x4b53..dbe6",
      to: "contractAddress",
      input: "0xabcd...",
      }

      • for WalletType is WEB or LIFF

      params = {
      type: "SmartContractExecution",
      from: "0x4b53..dbe6",
      to: "contractAddress",
      input: "0xabcd...",
      depositTokenAddress: "0xd077...", // USDT contract address
      depositAmount: "100" // Amount of USDT to transfer
      }

Note

An immediate update to Mini Dapp SDK v1.5.0 is not required. You may choose to update later when the official rebranding announcement is made. The added methods will function correctly after the launch of the rebranded Dapp Portal.
