🎉 We are thrilled to announce the release of version 1.0.0-alpha0 for java-stellar-sdk, which has been in development for nearly a decade. This release marks a significant milestone in our journey, as we have made substantial changes and improvements to enhance the functionality and usability of our software.

Please be aware that this release introduces breaking changes. We understand that this may cause inconvenience, but we believe these changes are necessary to rectify past design decisions and lay a solid foundation for the project's future. We have been cautious about introducing breaking changes in previous releases, but we feel this is the right time to make these important adjustments.

If you encounter any issues or have questions regarding the changes, please don't hesitate to submit an issue on our GitHub repository. Alternatively, you can reach out to me directly on the Stellar Dev Discord server. We value your feedback and are committed to addressing any concerns you may have.

Moving forward, we will be adopting semantic versioning starting from the official release of this version. This means that breaking changes will only be introduced in major version updates, providing more stability and predictability for our users.

It's important to note that this is an alpha release and should not be used in production environments. The purpose of this release is to gather feedback, identify and address any remaining issues, and ensure the stability and reliability of the software before the official release.

We appreciate your understanding and support as we work towards delivering a more robust and efficient solution. Thank you for being a part of our community, and we look forward to your continued engagement as we shape the future of this project together.

Update

  • feat: add support for Soroban PRC's getTransactions and getFeeStats API.
  • feat: add support for Horizon's transaction_async API.
  • feat: optimize RequestTimeoutException, when a timeout occurs, if the server returns some information, you can read them.
  • feat: add Asset.createNonNativeAsset(String, String) and Asset.createNativeAsset().
  • feat: add MuxedAccount class to represent a multiplexed account on Stellar's network.
  • feat: Add Server.loadAccount to load the Account object used for building transactions, supporting MuxedAccount.
  • feat: Add support for MuxedAccount to SorobanServer.getAccount.
  • feat: FeeBumpTransaction supports transactions that include Soroban operations.
  • feat: added a series of functions to parse xdr in the response.
  • fix: When calling TransactionBuilder.build(), the Soroban resource fee will be included in the fee of the built transaction.
  • fix: fix the issue where invoking SorobanServer.prepareTransaction for transactions that have already set SorobanData could result in unexpected high fees.
  • chore: Display the original definition in the XDR class documentation.
  • chore: add some examples, you can find them in the examples directory.
  • chore: bump dependencies.

Breaking changes

  • refactor!: Refactored the handling of exceptions.
    • Moved the Exception classes to the org.stellar.sdk.exception and org.stellar.sdk.federation.exception packages.
    • Most of the exceptions inherit from SdkException, and SdkException inherits from RuntimeException. Please refer to the following link to understand why we use unchecked exceptions: Why unchecked exceptions?
    • Renamed SorobanRpcErrorResponse to SorobanRpcException.
    • FormatException has been renamed to StrKeyException. When encode or decode strkey fails, StrKeyFormatException will be thrown.
    • Detailed the possible exceptions that may be thrown in the documentation.
    • In the previous code, there were instances where RuntimeException was directly thrown. We have now replaced these with more appropriate exceptions such as IllegalArgumentException.
  • refactor!: removed the check for network passphrase in Server, which means we will no longer verify if the network passphrase of transactions matches that of the Server, NetworkMismatchException has been removed.
  • refactor!: moved the Operation classes to the org.stellar.sdk.operations package.
  • refactor!: KeyPair.getSecretSeed returns null if the keypair does not contain a secret key.
  • refactor!: due to the lack of maintenance for net.i2p.crypto:eddsa, we have migrated to org.bouncycastle:bcprov-jdk18on. The constructor of KeyPair has changed, but you generally won't be affected by this change.
  • refactor!: refactor asset classes. LiquidityPoolParameters, LiquidityPoolConstantProductParameters, AssetTypePoolShare, LiquidityPoolShareChangeTrustAsset and LiquidityPoolShareTrustLineAsset have been removed. Use ChangeTrustAsset and TrustLineAsset instead.
  • refactor!: Server.submitTransactionXdr and Server.submitTransaction now return TransactionResponse instead of SubmitTransactionResponse. An exception will be thrown when the transaction submission fails. Please refer to the documentation for more information.
  • refactor!: Server.root() now returns RootRequestBuilder.
  • refactor!: In AllowTrustOperation, authorizeToMaintainLiabilities has been removed and the type of authorize has been changed to TrustLineEntryFlag. Please refer to the documentation for details.
  • refactor!: Previously, operations could be constructed through many methods; now, we have standardized them. Here is an example, please refer to the documentation for more details: 
    ClawbackClaimableBalanceOperation op = ClawbackClaimableBalanceOperation.builder()
  .balanceId(balanceId)
  .sourceAccount(source)
  .build();
  • refactor!: TransactionBuilder.IncrementedSequenceNumberFunc has been removed.
  • refactor!: Transaction.Builder has been removed, use TransactionBuilder instead.
  • refactor!: Asset.getType() returns org.stellar.sdk.xdr.AssetType instead of String.
  • refactor!: FeeBumpTransaction.Builder has been removed, use FeeBumpTransaction#createWithBaseFee(String, long, Transaction) or FeeBumpTransaction#createWithFee(String, long, Transaction) instead.
  • refactor!: FeeBumpTransaction.getFeeAccount has been removed, use FeeBumpTransaction.getFeeSource instead.
  • refactor!: remove AccountConverter, this means that we no longer support disabling support for MuxedAccount.
  • refactor!: refactor the way of constructing Predicate.Or and Predicate.And. The inner inside has been removed, and in its place are left and right, used to represent two predicates.
  • refactor!: Refactored response classes.
    • Utilized wrapper classes, such as replacing int with Integer, long with Long, boolean with Boolean, etc.
    • If a field is a list, we now use List instead of arrays.
    • The types of some fields have been modified.
    • Removed some methods.
    • Some field names have been changed to maintain consistency with the Horizon API.
    • Removed all functions that return Optional value.
  • refactor!: remove rateLimitLimit, rateLimitRemaining, and rateLimitReset from the Response. Horizon does not return these fields.
  • refactor!: TransactionBuilder#TransactionBuilder(Transaction) has been removed, because the TransactionBuilder constructed from the transaction may be inconsistent with what the user expects.
  • refactor!: remove LiquidityPoolID. Use String to represent the liquidity pool ID.
  • refactor!: LiquidityPoolWithdrawOperation#LiquidityPoolWithdrawOperation(AssetAmount, AssetAmount, String) has been removed. Use LiquidityPoolWithdrawOperation#LiquidityPoolWithdrawOperation(Asset, BigDecimal, Asset, BigDecimal, BigDecimal) instead.
  • refactor!: LiquidityPoolDepositOperation#LiquidityPoolDepositOperation(AssetAmount, AssetAmount, Price, Price) has been removed. Use LiquidityPoolDepositOperation#LiquidityPoolDepositOperation(Asset, BigDecimal, Asset, BigDecimal, Price, Price) instead.
  • refactor!: the type of the following field has been changed from String to BigDecimal.
    • ChangeTrustOperation.limit
    • ClawbackOperation.amount
    • CreateAccountOperation.startingBalance
    • CreateClaimableBalanceOperation.amount
    • CreatePassiveSellOfferOperation.amount
    • LiquidityPoolDepositOperation.maxAmountA and LiquidityPoolDepositOperation.maxAmountB
    • LiquidityPoolWithdrawOperation.amount, LiquidityPoolWithdrawOperation.minAmountA, and LiquidityPoolWithdrawOperation.minAmountB
    • ManageBuyOfferOperation.amount
    • ManageSellOfferOperation.amount
    • PathPaymentStrictReceiveOperation.sendMax and PathPaymentStrictReceiveOperation.destAmount
    • PathPaymentStrictSendOperation.sendAmount and PathPaymentStrictSendOperation.destMin
    • PaymentOperation.amount
  • refactor!: TransactionPreconditions#TransactionPreconditions(LedgerBounds, Long, BigInteger, long, List, TimeBounds) has been removed, use TransactionPreconditions#TransactionPreconditions(TimeBounds, LedgerBounds, Long, BigInteger, long, List) instead.
  • refactor!: The Federation has been refactored, please use Federation#resolveAddress(String) and Federation#resolveAccountId(String, String) now.
  • refactor!: Set the default value of TransactionPreconditions.extraSigners to new ArrayList<>(), it is not nullable.
