node-sdk v8.0.0

Breaking changes

• Proper Errors are thrown when execution fails for any WASM entrypoint, and error messages have been improved.
• Updated types.ts to conform to updated GRPC API, which includes adding more variants to existing types (all new variants take effect from protocol version 6):
  • ChainParametersV2 added to ChainParameters
  • BlockInfo changed to BlockInfoV0 | BlockInfoV1
  • ConsensusStatus changed to ConsensusStatusV0 | ConsensusStatusV1
  • ElectionInfo changed to ElectionInfoV0 | ElectionInfoV1

Fixed

• Cost calculation for deployModule transaction.
• Fixed a bug where protocol version was different (i.e. 1 less than what it should be) when using the gRPCv2 API (compared to what is returned by the gRPCv1 API).

Added

• A parseWallet function to parse wallet export files
• Helper functions to determine version of versioned types mentioned in "Breaking Changes" have been added.
• Support for new chain update types.
• Function uleb128DecodeWithIndex that can also parse more than a single ULEB128 bigint
• Added tokenAddressFromBase58 and tokenAddressToBase58 to CIS2

Changed

• Function uleb128Decode now parses correctly and throws an error if the given input contains more than a single ULEB128 encoded number.
• The following functions now all have an additional parameter controlling whether errors are in a verbose format or not:
  • deserializeContractState
  • deserializeReceiveReturnValue
  • deserializeReceiveError
  • deserializeInitError
  • deserializeTypeValue
  • serializeInitContractParameters
  • serializeUpdateContractParameters
  • serializeTypeValue

web-sdk v4.0.1

Fixed

• Cost calculation for deployModule transaction.

web-sdk v4.0.0

Breaking changes

• Updated blockInfo so that the bakerId field is optional, since it will be undefined for genesis blocks.
• waitForTransactionFinalization now returns a BlockItemSummaryInBlock
• Added missing version return type in getModuleSchema. It now returns an object containing the schema source and version.

Added

• Helpers for calculating energy cost for a transaction and microCCD cost from energy cost:
  • getEnergyCost
  • getExchangeRate
  • convertEnergyToMicroCcd
• Utility functions for extracting information from BlockItemSummary:
  • isInitContractSummary
  • isUpdateContractSummary
  • isTransferLikeSummary
  • isRejectTransaction
  • isSuccessTransaction
  • getTransactionRejectReason
  • getReceiverAccount
  • affectedContracts
  • affectedAccounts
• Utility functions for extracting information from BlockSpecialEvent:
  • specialEventAffectedAccounts
• Helper methods on GRPCClient for chain traversal:
  • getFinalizedBlocksFrom
  • findEarliestFinalized
  • findInstanceCreation
  • findFirstFinalizedBlockNoLaterThan
• Extended HdWallet with support for verifiable credential key derivation.

web-sdk v3.5.0

• Utility functions uleb128Decode and uleb128Encode for decoding and encoding as unsigned leb128 respectively.
• CIS2Contract class for interacting with smart contracts adhering to the CIS-2 standard.
• cis0Supports function for checking standard support in smart contracts.
• Made the streamToList() function public.
• Build function buildAccountSigner for creating AccountSigner objects from genesis format, wallet export format, and a simple representation of credentials with keys.

node-sdk v6.4.0

• Utility functions uleb128Decode and uleb128Encode for decoding and encoding as unsigned leb128 respectively.
• CIS2Contract class for interacting with smart contracts adhering to the CIS-2 standard.

web-sdk v3.4.2

generateBakerKeys function now also returns the private baker keys.

web-sdk v3.4.1

Fix the gRPCv2 client's helper function waitForFinalization, so it doesn't use setImmediate, which is not supported in the browser.

web-sdk v3.4.0

• Added a general function for deserializing smart contract values deserializeTypeValue.
• signMessage and verifyMessageSignature can now handle the message being a buffer/Uint8Array instead of only a utf8 string.
• Updated dependencies to fix incorrect serialization of negative numbers for smart contract values.
• serializeTypeValue now reports an error when called with invalid data, such as a receive function with missing schema, or a schema that cannot be parsed.
