v6.3.0

New Features

• Added trx.getContractInfo

  Added trx.getContractInfo(contractAddress) method that retrieves detailed contract information via the wallet/getcontractinfo node API endpoint.

• Extended deserializeTx with full contract type coverage

  Added deserialization support for all remaining TransactionBuilder contract types via raw_data_hex:

  • Account: AccountCreateContract, AccountUpdateContract, SetAccountIdContract, AccountPermissionUpdateContract
  • Stake / Vote: FreezeBalanceContract, UnfreezeBalanceContract, VoteWitnessContract
  • Proposal: ProposalCreateContract, ProposalApproveContract, ProposalDeleteContract
  • Smart contract: CreateSmartContract, UpdateSettingContract, UpdateEnergyLimitContract, ClearABIContract
  • DEX: ExchangeCreateContract, ExchangeInjectContract, ExchangeWithdrawContract, ExchangeTransactionContract
  • UpdateBrokerageContract

Improvements

• Plugin restrictions

  • Added PROTECTED_MODULES to prevent plugins from overriding 2 modules: transactionBuilder, plugin.
  • Added PROTECTED_METHODS to block plugins from overriding critical signing/key methods: sign, signMessage, signMessageV2, signTransaction, signTypedData, multiSign, setPrivateKey, ecRecover.
  • ⚠️ Note: Plugin support will be removed in the next major version.

• Bug fix

  • Corrected the return type of the getDelegatedResourceV2 in trx.ts to consistently return an array.

Changes

• Remove dev dependency @eslint/eslintrc.
• Bump serialize-javascript from 7.0.3 to 7.0.5.

v6.2.2

New Features

• Added getCreate2Address

  • Added support for utils.address.getCreate2Address utility method.

  • Enables deterministic contract address computation using CREATE2.

  • Useful for advanced contract deployment workflows and meta-deployment scenarios.

Improvements

• Improvement in decodeParams

  • Replaced {} with Object.create(null) in decodeParams.

  • Prevents prototype pollution.

• Robust argument encoding in encodeArgs

  • Prevents valid falsy values from being incorrectly ignored.

  • Improves reliability of contract parameter encoding.

• Strict contract type validation in contractJsonToProtobuf

  • Now throws an explicit error when encountering unsupported contract.type.

  • Prevents silent failures during contract conversion.

  • Improves developer debugging experience.

v6.2.1

Changes

• Bump axios from v1.12.2 to v1.13.5
• Bump webpack from v5.98.0 to v5.105.2

v6.2.0

New Features

• trx.getNowWitnessList
  Added a new method to retrieve the witness list with real-time vote counts. This feature is available for JAVA-TRON v4.8.1 and above.

• New deserialization support
  Added support for deserializing the following transaction types from raw_data_hex:

  • TransferAssetContract
  • ParticipateAssetIssueContract
  • AssetIssueContract
  • UpdateAssetContract

v6.1.1

Changes

• Remove dependency jsonwebtoken.
• Bump validator from v13.15.20 to v13.15.23.
• Address other audit issues.

v6.1.0

New Features

• New deserialization support
  Added support for deserializing the following transaction types from raw_data_hex:

  • TransferContract
  • WithdrawBalanceContract
  • WitnessCreateContract

• trx.getCurrentRefBlockParams
  Provides a method to retrieve the parameters required for transaction building. Users can pass these parameters to transaction constructors and customize the header information, making transaction creation more convenient.

• trx.signTypedData alias
  Added trx.signTypedData as an alias pointing to the legacy trx._signTypedData method.

Changes

• Removed getHeaderInfo from the transactionBuilder helper library. Use trx.getCurrentRefBlockParams instead.

• Moved the deserializeTransaction function from utils/transaction to utils/deserializeTx for better scalability and maintainability of future modules.

• Dependency updates:

  • axios upgraded from 1.11.0 to 1.12.2
  • puppeteer upgraded from 24.4.0 to 24.23.0

v6.0.4

New Features

• Improve type inference in Contract module when using typescript.
  • The Contract now infers method signatures based on the provided ABI.
  • To enable accurate inference, the ABI should be defined using the as const assertion or passed directly into tronWeb.contract().

Change

• Change the return behavior of the contract.new() method.
  • Previously, this method mutated the current instance and used the ABI stored on the Tron blockchain, which proved to be unreliable. It now returns a new instance that uses the ABI provided in the options parameter.
• Export GetEventResultOptions and EventResponse.
• Allow using length as the value of the name field in the ABI, but you cannot use result['length'] to read its value.
• Bump axios from 1.8.3 to 1.11.0, bump eslint from 9.22.0 to 9.31.0.

Bug Fixes

• Fix the issue where addUpdateData treats numeric strings as numbers.#629
  • Starting from TronWeb v6.0.4, addUpdateData will use TronWeb.fromUtf8 to convert the provided data string—unless it starts with '0x'.
  • If the resulting data string has an odd length, a '0' will be prepended to ensure even length.

v6.0.3

• Add support for deserializing 6 more transactions.
• Fix npm audit issues.
• Fix the error in the abi variable within transactionBuilder.createSmartContract.
• Export Method class.
• Add missing fields in internal_transactions.

v5.3.4

• Fix CSP problem in the TransactionBuilder.vote function.

v5.3.3

• Update dependencies to address audit problems.
