## **Summary**

This proposal recommends that the Lido DAO sponsors the development of the **Atupa Unified Execution Suite**. Atupa is a high-performance Rust-native profiler designed to monitor and audit complex “Mixed-VM” transactions (Solidity + Stylus). By providing high-fidelity visibility into stETH’s execution path on L2s like Arbitrum, Atupa will enhance the protocol’s resilience and risk-monitoring capabilities for its largest integrations.

## **Introduction**

As the liquid staking leader, Lido’s growth is increasingly tied to its resilience on Layer 2 ecosystems. However, new technical developments like **Arbitrum Stylus (WASM)** represent a “Visibility Black Hole” for current monitoring tools. Transactions that move between standard Solidity (EVM) and high-performance Rust (WASM) cannot be audited by standard tracers in a single contiguous journey. This opacity introduces hidden risks for stETH during cross-VM liquidations or complex facilitator logic.

## **Project Description: The Atupa Unified Suite**

Atupa is a local-first, high-performance tracing engine built in Rust. Unlike specialized tracers, Atupa is designed for **Unified Execution Visibility**.

Key technical features include:

- **Mixed-VM Trace Stitching** : Merging standard `callTracer` data with Arbitrum `stylusTracer` HostIOs to provide a 100% complete execution path.

- **Ink & Gas Analysis** : Normalizing Stylus “Ink” and EVM “Gas” to identify performance bottlenecks in hybrid vaults.

- **Institutional Protocol Adapters** : Pre-built logic for auditing **Aave v3** , **GHO** , and **lending-market health** specifically for stETH pairings.

## **Value to Lido DAO**

Sponsoring Atupa aligns directly with Lido’s **GOOSE-3** goals for “Protocol Resilience”:

1. **Enhanced Risk Observability** : Provides the Lido Risk Council with the first “X-Ray” view for stETH integrations on Hybrid L2s.

2. **Early Regression Detection** : Identifies execution-level inefficiencies or gas-spikes in wSTETH facilitators before they impact capital efficiency.

3. **Resilience Moat** : Establishes a gold standard for transparency as the ecosystem moves toward high-performance Rust/WASM contract logic.

## **Milestones & Timeline (8 Weeks)**

### **Milestone 1: The Nitro Unified Adapter (Week 1–4)**

- **Deliverable** : Integration of Arbitrum Nitro’s dual-trace architecture into the Atupa engine.

- **Outcome** : A functional CLI tool (`cargo-atupa`) capable of stitching Solidity-WASM transitions.

### **Milestone 2: Lido Resilience Module (Week 5–8)**

- **Deliverable** : Specialized decoders for major stETH integration addresses (e.g., Aave v3 wstETH pool).

- **Outcome** : Automated “Health Reports” and high-fidelity flamegraphs for stETH execution paths.

## **Team**

**One Block** is an infrastructure collective focused on Ethereum execution transparency.
