v16.1.0

v16.1.0

Added

• inspectAuthEntry(entry): decodes a xdr.SorobanAuthorizationEntry into a typed summary — credential type, authorizing address, nonce, signatureExpirationLedger, and a signers list covering top-level credentials and CAP-71 delegates. Adds the AuthEntryInfo, AuthEntrySigner, AuthEntrySignature, and AuthEntryCredentialType types (#1529).
• checkAuthEntryReadiness(entry, currentLedgerSeq): reports whether an auth entry is ready to submit — { ready, expired, unsignedBy } — as a pure decode with no network call (#1529).
• Spec.nativeToScVal now supports contract parameters typed as Val (scSpecTypeVal), so raw JS values can be passed to Val-typed arguments without building xdr.ScVal objects by hand (#1485).
• rpc.Server.queryContract<T>(contractId, method, args?, networkPassphrase?): a one-line read-only contract call that returns { result, isReadCall }, no transaction assembly or signing. Works for Wasm contracts and built-in Stellar Asset Contracts (SACs) (#1502).
• rpc.Server.getContractMethods(contractId, networkPassphrase?): lists a contract's callable methods and their signatures. Adds the Api.ContractMethod and Api.ContractMethodInput types (#1502).
• rpc.Server.getContractInstance(contractId): returns a contract's xdr.ScContractInstance (#1501).
• contract.Client.from, fromWasm, and fromWasmHash are now generic (<T>) and return Client & T, giving typed contract methods without code generation. T defaults to unknown, so untyped calls are unchanged (#1502).
• ClientOptions.server: pass an existing rpc.Server to contract.Client.from to reuse its transport instead of building a new one (#1502).
• Keypair.signMessage(message) and Keypair.verifyMessage(message, signature): sign and verify arbitrary messages per SEP-53, matching the Python and Java SDKs and stellar-cli (#1513).
• TransactionFailedError: raised by Horizon.Server.submitTransaction and submitAsyncTransaction when Horizon rejects a transaction with result codes. Extends BadResponseError and adds getResultCodes() and getTransactionResult() (#1526).

Changed

• HorizonApi.TransactionFailedResultCodes gained the transaction result codes it was missing: tx_bad_sponsorship, tx_bad_min_seq_age_or_gap, tx_malformed, tx_soroban_invalid, and tx_frozen_key_accessed (#1526).
• contract.Client.from now supports built-in Stellar Asset Contracts (SACs), building the client from the embedded SAC spec instead of downloading Wasm (#1501).
• rpc.Server.getContractWasmByContractId now rejects a SAC with a structured { code: 400 } error pointing to contract.Client.from. The not-found rejection is now { code: 404, message: "Could not obtain contract instance from server" } (#1501).
• The UMD (dist/) build now sets inlineDynamicImports so the single-file bundle stays whole despite the SAC spec's lazy import() (#1501).

Fixed

• Horizon.Server.submitTransaction and submitAsyncTransaction now reject with SDK error types on HTTP failures, as documented: a TransactionFailedError for Horizon result codes, a BadResponseError otherwise. The wrapping branch used to be unreachable, so failures leaked through as raw HTTP-client errors. err.response.data and err.response.status are unchanged; the original error is now preserved as err.cause (#1526).
• Federation.Server resolution methods (resolveAddress, resolveAccountId, resolveTransactionId, forDomain) had the same unreachable branch and now reject HTTP failures with BadResponseError (#1526).
• contract.AssembledTransaction.needsNonInvokerSigningBy now treats an empty scvVec signature as unsigned, matching the existing scvVoid check. Such entries used to count as already signed and were left off the list (#1529).
• Spec.nativeToScVal no longer misclassifies plain objects that have a constructor key, and handles null-prototype objects (Object.create(null)) (#1485).

v16.0.1

v16.0.1

Fixed

• Fixed the ESM library build so the inlined @stellar/js-xdr source resolves correctly under Yarn PnP (and Node's native ESM resolver). Because the build preserves modules, Rollup emits js-xdr's source into a nested package scope, but js-xdr does not declare type: "module", so Node and Yarn PnP parsed those preserved files as CommonJS and failed to resolve them. Rollup now marks the emitted js-xdr package as type: "module" so its source is parsed as ESM #1484.

v16.0.0

There are a few major updates in this release:

• JS Stellar Base (@stellar/stellar-base) was rewritten in TypeScript, which provides proper type definitions and fixes inconsistencies caused by manual type declarations. (#1399)
• JS Stellar Base is now merged into the JS Stellar SDK. Everything lives in one
