All notable changes to the Vilna API will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

This release is a full redesign of the platform architecture and API surface. It represents a stable, production-ready beta ready for integration and early adoption.

Access: Available by request at support@vilna.io

• Added: 31 blockchain networks - Ethereum, Bitcoin, Tron, Solana, TON, Cosmos, BSC, Polygon, Arbitrum, Optimism, Avalanche, Base, and 19 more. Each network supports address derivation, balance tracking, and transaction monitoring.
• Added: Core API resources - Public Keys, Addresses, Transactions, Balances, Tokens, and Notification Channels. Consistent REST interface across all resources with page-based pagination.
• Added: Transaction processing - Query transactions, simulate EVM calls. Pre-execution preview shows expected outcomes before broadcasting.
• Improved: Security model - API key authentication, rate limiting. All API calls are authenticated and auditable.

• Added: New documentation site - Built on Redocly Realm at docs.vilna.io. Covers platform overview, integration guides, and full API reference.
• Added: Interactive API reference - Generated from OpenAPI 3.1 spec with try-it-out functionality, request/response examples, and schema documentation.
• Added: Bilingual support - Full English and Russian localization for all documentation and UI.
• Added: Business documentation - Use cases, adoption guides, and access plans for non-technical stakeholders.

• Added: TypeScript SDK - @vilna/sdk package with typed API client and automatic pagination.
• Added: OpenAPI 3.1 specification - 50+ endpoints fully documented. Machine-readable spec enables code generation for any language.
• Added: Standards compliance - CAIP-2 for chain identification, CAIP-10 for account addresses, CAIP-19 for asset types, BIP-44 for HD wallet derivation paths.
• Improved: Webhook system - Real-time notifications for balance changes, transaction confirmations, and address activity, with retry logic. HMAC signature verification is planned for an upcoming release.

If you integrated with the initial beta, note the following changes:

• The API has been completely rebuilt. All endpoints have new request/response schemas.
• Base URL format changed to https://{namespace}.vilna.app.
• Authentication uses the X-Api-Key header.
• See the Platform API for the current specification.
