In 0.8.1 the handler returned the bare inner frame [0x84][signer][sig][extras][callData] — but RPC and polkadot-api decoders expect the outer wire form with a leading compact length, so byte 0 (0x84) was read as part of the length and decoding failed. Prepend compactToU8a(inner.length) to the returned bytes so the extrinsic is wire-ready. Updated integration test #45 to strip the compact prefix before asserting on the v4 frame; the assertion now also verifies that the compact-decoded length matches the inner body length.

@novasamatech/*to0.7.9-4and fixeshandleCreateTransactionto return a real signed v4 extrinsic on the wire. Earlier0.8.xreleases either echoedcallDataback or returned the inner extrinsic frame without its SCALE-compact length prefix — both of which fail the moment a product tries to submit the bytes through polkadot-api / RPC.What changed
handleCreateTransaction/handleCreateTransactionWithLegacyAccount— the request is now a flat object (signer,genesisHash,callData,extensions,txExtVersion); no more tuple wrapping, nocontextblock, all fields areUint8Array. ExportsVersionedPublicTxPayload/TxPayloadV1Publicare gone — useProductAccountTransaction/LegacyTransaction.callData || extras || additionalSignedwith sr25519 and returns the full v4 wire form:[compact len][0x84][MultiAddress::Id + AccountId32][Sr25519 + sig][extras][callData]. v5 is not emitted yet (paseo-asset-hub-next runsextrinsic.version: [4]only).@novasamatech/product-sdkis being renamed to@novasamatech/host-api-wrapper(0.7.9-5+is under the new name; we stay onproduct-sdk@0.7.9-4for this release).What you need to do
0.8.2. No product-side code change required — the wrapper API didn't move.createTransactionrequests by hand, switch to the flatProductAccountTransactionshape and includegenesisHash.callData, drop that assumption and decode the response as a v4 extrinsic instead.0.8.0and0.8.1are superseded; skip straight to0.8.2.
