Streamflow JS SDK Release Notes

v10.0.0

Removed Payments Stream Type: The StreamType.Payment enum value has been removed. The StreamType enum now only includes All, Vesting, and Lock. If your code references StreamType.Payment, you'll need to update it to use one of the remaining types or remove the reference.
Removed Multi-Chain Support: All non-Solana blockchain implementations have been removed from the SDK:
- Aptos support removed (packages/stream/aptos/)
- EVM (Ethereum/Polygon/Avalanche) support removed (packages/stream/evm/)
- Sui support removed (packages/stream/sui/)
- The SDK is now Solana-only. If you were using any of these implementations, please see the v9 branch of the SDK which we will continue to support, but not activelty improve or add new features.
Removed GenericStreamClient: The GenericStreamClient and BaseStreamClient classes have been removed. The SDK now only provides SolanaStreamClient (exported as SolanaStreamClient). Update your imports:
- Before: import { GenericStreamClient } from "@streamflow/stream/common"
- After: import { SolanaStreamClient } from "@streamflow/stream"
Partner Fee Structure Changes: The partner fee structure has been updated. The partner parameter now defaults to the sender's address if not provided. Review your stream creation code to ensure partner fees are configured correctly.

Price-based Streams (Aligned Streams) Documentation: Added comprehensive documentation for creating and managing price-based streams that dynamically adjust unlock rates based on token price oracles. The documentation includes:
- Creating price-based vesting streams
- Creating price-based token locks
- Fetching and accessing aligned stream data
- Integration with Streamflow's Oracle API

Improved Metadata Handling: Enhanced support for custom metadata public keys via the metadataPubKeys parameter in stream creation methods. You can now pass an array of metadata public keys for batch operations.
Fixed Double ATA Creation: Resolved an issue where WSOL (wrapped SOL) streams would attempt to create duplicate Associated Token Accounts when the recipient and sender were the same address.
Removed Treasury ATA Creation: The SDK no longer automatically creates Streamflow treasury ATA accounts, reducing transaction size and costs.
Squads Ephemeral Signatures Support: Fixed support for Squads multisig wallets using ephemeral signatures.
Better Error Handling: Improved error handling and null/undefined checks throughout the SDK.

Enhanced @streamflow/stream README with detailed examples for price-based stream creation
Added examples for fetching aligned stream properties using getOne(), get(), and searchStreams()
Documented Oracle API integration for fetching price oracle addresses
Removed references to non-Solana chains from documentation

If you're upgrading from v8.x or v9.x to v10.0.0:

Update Imports: * Remove any imports from @streamflow/stream/common, @streamflow/stream/aptos, @streamflow/stream/evm, or @streamflow/stream/sui * Use only @streamflow/stream for Solana-specific imports * Replace GenericStreamClient with SolanaStreamClient
Update Stream Type References: * Remove any code that references StreamType.Payment * Update your code to use StreamType.Vesting, StreamType.Lock, or StreamType.All
Review Partner Fee Configuration: * If you were explicitly setting partner to undefined or relying on default behavior, verify that the new default (sender address) works for your use case * Update partner fee logic if needed
Update Dependencies: * Remove any non-Solana blockchain dependencies from your package.json * Ensure you're only using Solana-related packages
Test Metadata Handling: * If you're using custom metadata public keys, test that the new metadataPubKeys array parameter works correctly with your implementation
