v12.0.0-rc.3: Protocol 21 Release Candidate 3

This update supports Protocol 21. It is an additive change to the protocol so there are no true backwards incompatibilities, but your software may break if you encounter new unexpected fields from this Protocol (#949).

Breaking Changes

• ContractClient functionality previously added in v11.3.0 was exported in a non-standard way. You can now import it as any other stellar-sdk module (#962):

-import { ContractClient } from '@stellar/stellar-sdk/lib/contract_client'
+import { contract } from '@stellar/stellar-sdk'
+const { Client } = contract

Note that this top-level contract export is a container for ContractClient and related functionality. The ContractClient class is now available at contract.Client, as shown. Further note that there is a capitalized Contract export as well, which comes from stellar-base. You can remember which is which because capital-C Contract is a class, whereas lowercase-c contract is a container/module with a bunch of classes, functions, and types.

Additionally, this is available from the /contract entrypoint, if your version of Node and TypeScript support the exports declaration. Finally, some of its exports have been renamed:

import {
   AssembledTransaction,
   SentTransaction,
-  ContractClient,
-  ContractClientOptions,
-} from '@stellar/stellar-sdk/lib/contract_client'
+  Client,
+  ClientOptions,
+} from '@stellar/stellar-sdk/contract'

• The ContractSpec class is now nested under the contract module, and has been renamed to Spec (#962). Alternatively, you can import this from the contract entrypoint, if your version of Node and TypeScript support the exports declaration:

-import { ContractSpec } from '@stellar/stellar-sdk'
+import { contract } from '@stellar/stellar-sdk'
+const { Spec } = contract
// OR
+import { Spec } from '@stellar/stellar-sdk/contract'

• Previously, AssembledTransaction.signAndSend() would return a SentTransaction even if the transaction never finalized. That is, if it successfully sent the transaction to the network, but the transaction was still status: 'PENDING', then it would console.error an error message, but return the indeterminate transaction anyhow. It now throws a SentTransaction.Errors.TransactionStillPending error with that error message instead (#962).

Deprecated

• SorobanRpc module is now also exported as rpc (#962). You can import it with either name for now, but SorobanRpc will be removed in a future release:

-import { SorobanRpc } from '@stellar/stellar-sdk'
+import { rpc } from '@stellar/stellar-sdk'

You can also now import it at the /rpc entrypoint, if your version of Node and TypeScript support the exports declaration.

-import { SorobanRpc } from '@stellar/stellar-sdk'
-const { Api } = SorobanRpc
+import { Api } from '@stellar/stellar-sdk/rpc'

Added

• New methods on contract.Client (#960):
  • from(opts: ContractClientOptions) instantiates contract.Client by fetching the contractId's WASM from the network to fill out the client's ContractSpec.
  • fromWasm and fromWasmHash methods to instantiate a contract.Client when you already have the WASM bytes or hash alongside the contract.ClientOptions.
• New methods on rpc.Server (#960):
  • getContractWasmByContractId and getContractWasmByHash to retrieve a contract's WASM bytecode via its contractId or wasmHash, respectively.

Fixed

• The breaking changes above (strictly speaking, they are not breaking changes because importing from the inner guts of the SDK is not supported) enable the contract module to be used in non-Node environments.
