WindStack SDK v2.2.0

WindStack 2.2.0 improves wallet sessions, embedded dApp support, and transaction signing across Vexanium applications.

Highlights

• Added persistent Vexanium wallet sessions with restore, disconnect, revoke, and cold-start recovery support.
• Added secure embedded dApp provider and wallet host support while preserving the standard Vexanium provider flow.
• Added persistent Wisp Wallet support for Telegram Mini Apps.
• Improved session recovery after reload, reopen, expiration, revoke, and conflicting wallet state.
• Improved deterministic multi-action signing-request resolution while preserving the complete transaction through review and signing.
• Added regression coverage for multi-action liquidity transactions.
• Improved VEX Native and VEX EVM wallet account handling.
• Consolidated Telegram connection handling around the canonical WindStack transport.
• Improved restored-session validation before wallet state is reused.
• Expanded release, runtime compatibility, session, and transaction regression coverage.

WindStack SDK v2.1.0

• Added canonical transaction deserialization with size and count limits plus canonical round-trip verification.
• Preserved structured transactions through Vexanium wallet signing so complete multi-action transactions can be reviewed before approval.
• Added structured transaction and serialized context-free-data fields to exact signing with byte-for-byte consistency checks.
• Added high-level Vexanium transaction APIs for ABI-aware action construction, wallet authorization, TAPOS preparation, signing, and optional broadcast.
• Updated client-bound VSR creation to use the configured Vexanium RPC and ABI cache.
• Added VSR action inspection and ABI-aware decoding for single-action, multi-action, and full-transaction requests.
• Added ABI request deduplication for concurrent action resolution and shared ABI caching.
• Restricted Vexanium-facing signing-request and exact-signing operations to VSR and the configured Vexanium chain.
• Updated signing-request revision selection to use the minimum compatible protocol revision for each request.
• Strengthened provider capability negotiation, chain and session validation, malformed transaction handling, and wallet response validation.

WindStack SDK v2.0.0

WindStack 2.0.0 establishes a general-purpose, application-neutral SDK surface.

Highlights

• Exact bigint decimal, asset, precision, fee, slippage, AMM, routing, and liquidity primitives.
• VEX, EOS, PUB_K1, PUB_R1, PVT_K1, and WIF compatibility with canonical K1 signing and recovery.
• Transaction serialization, digest, ID, TAPOS, chain verification, safe RPC failover, Spring finality, and Hyperion history fallback.
• keosd signing over HTTP and Node.js Unix sockets.
• Generic EVM address, chain, provider, session, and JSON-RPC utilities.
• Vexanium native account and reserved EVM bridge address conversion, bridge calldata decoding, and strict vex.evm action decoding.
• Hardened release checks, Node.js 20, 22, and 24 coverage, complete declaration output, and verified tarball installation.

Changes

• Vexanium-specific Antelope configuration moved to @windstack/vexanium/antelope.
• VEX EVM chain metadata moved to @windstack/vexanium.
• Lossy numeric asset conversion and duplicate application-facing helpers were removed.

See CHANGELOG.md for the complete migration summary.

WindStack SDK v1.0.0

WindStack 1.0.0 is the initial stable release of the WindStack SDK.

Highlights

• Modular packages for Antelope, Vexanium, EVM, Solana, ABI, RPC, contracts, accounts, sessions, signing requests, and wallet integration.
• Typed ESM packages with declaration files and documented public entry points.
• Browser and Node.js support across the published package set.
• Established the initial stable SDK surface for application and wallet integrations.

This release is retained as the 1.x baseline. For new integrations, use the latest WindStack release.
