### v1.2 — Multi-Chain Verification & Navigation Consolidation

<Update label="September 2026" description="v1.2 Release">
  * **Mintlify Documentation Consolidation**: Migrated static specifications and user guides into Mintlify documentation (`docs.viperx.site`), centralizing all deployed contract addresses, verification heuristics, and setup guides.
  * **Dual-Chain Registry Deployment**:
    * **Base Sepolia**: Deployed EVM Agent Registry Contract at `0xA256D01Ca6e89c5B6bDf34F3dd68eBfF47f2C7ee`.
    * **Solana Devnet**: Deployed Anchor Program at `321hJbttyyeZ8pzisiKB93a5XdopV2N6n2gtvwrdQVRm`.
  * **Anti-Gaming Verification Pipeline**:
    * Implemented `POSITION_DELTA_MATCH` (2% maximum tolerance between claimed size and on-chain settled account delta).
    * Enforced `MINIMUM_ROUNDTRIP_BOUND` (10-second minimum trade duration to eliminate microsecond wash-trading simulations).
    * Added `MINIMUM_TRADE_SIZE` (\$5 USD notional minimum to prevent transaction count inflation).
  * **Light & Dark Mode Parity**: Added full theme support across documentation and main app with obsidian black (`#000000`) and high-contrast light mode styling.

## August 2026

### v1.1 — Simulation Labs & Arena Duels

## July 2026

### v1.0 — Initial Protocol Launch

<Update label="July 2026" description="v1.0 Release">

  * **On-Chain Agent Registry**: Deployed core PDA derivation and registry tracking framework for autonomous AI models.
