## Security audit rollout  
HackenProof opened the DualDefense audit for KiiChain’s L1 in March 2026, defining a “critical vulnerability” as one with both high likelihood and high impact and offering a full‑bounty reward to a sole discoverer of such a flaw [1]. The program’s bounty structure splits rewards among multiple reporters when the same issue is submitted, with each participant receiving 50 % of the allocated pool for shared findings. This framework incentivizes thorough testing while protecting the project from public disclosure of unresolved issues, as required by the program’s terms.

## Software upgrade timeline  
The KiiChain codebase, hosted on GitHub, saw its most recent tagged release v4.0.0 in April 2025 [2]. The update upgrades the Inter‑Blockchain Communication (IBC) protocol, refreshes Swagger and Oracle parameters, and introduces a new Oracle module—key components for reliable cross‑chain FX settlements. Earlier releases (v3.0.0 and v2.0.0) documented testnet upgrades on the Oro network at heights 17,988,405 (scheduled 2 Apr 2025) and 14,513,051 (26 Feb 2025) respectively [2]. The repository was archived on 28 Apr 2025, rendering it read‑only but preserving the full changelog for reference.

## Platform capabilities and ecosystem  
KiiChain positions itself as a fast, scalable CometBFT‑based blockchain delivering up to 12,000 transactions per second with ~1‑second block times [4]. Its on‑chain FX layer supports 24/7 stablecoin swaps, cross‑border payments across 100+ chains, and a suite of financial services—including AI‑driven FX agents, non‑custodial wallets, and institutional liquidity provision for over 350 clients [3]. The recent Oracle module addition enhances price feed reliability, a prerequisite for the platform’s “real‑time FX orchestration” claim.

## What to watch
- **Audit outcome** – Monitor HackenProof’s final report for any disclosed critical findings that could affect KiiChain’s security posture.  
- **v4.0.0 deployment** – Track the actual activation of the v4.0.0 upgrade on the Oro testnet at height 17,988,405; any delay may indicate integration challenges.  
- **Oracle performance** – Observe on‑chain price feed latency and accuracy after the Oracle module launch, as it underpins the platform’s FX settlement guarantees.

The convergence of a rigorous security audit and a substantive software upgrade underscores KiiChain’s effort to harden its infrastructure while expanding functional breadth. How the audit’s findings and the Oracle module’s performance unfold will shape confidence among developers and institutional partners seeking a stable, interoperable FX layer.
