Auralis is a protocol-engineering portfolio repository focused on security-first, upgrade-aware Solidity systems. It combines modular contract design, deployment-backed validation, local operator flows, hardening coverage, and standalone smart-wallet execution so a reviewer can assess architecture and evidence together rather than as isolated snippets.

Why This Repo Exists

This repo is meant to demonstrate more than isolated contract snippets. It shows how access control, guard rails, oracle safety, vault logic, diamond routing, deployment scripts, rehearsal flows, and CI checks fit together as a reviewable engineering system.

What This Repo Proves

• Core architecture: diamond routing, selector ownership discipline, and separate hosted token and vault deployment models plus standalone AMM and smart-wallet tracks.
• Safety posture: RBAC, timed permissions, pause semantics, reentrancy protection, oracle validation, upgrade guardrails, and threshold-based wallet execution.
• Token hosts: ERC20 and ERC721 diamond deployments with role, pause, Permit, metadata, and selector ownership coverage.
• Vault platform: hosted ERC-4626 vaults with controls, strategy integration, native-asset support, and an ERC-7540 async request track for ERC-20 hosts.
• AMM track: standalone V2-style AMM with deterministic pair deployment, wrapped-native routing, pricing math, and protocol-fee controls.
• Wallet track: standalone multisig wallet with single-call, batch, and self-managed configuration flows.
• Operational maturity: local bootstrap, smoke validation, activity flows, upgrade rehearsal, and matching CI/hardening gates.

Validation Path

Foundry uses the Solidity compiler pinned in foundry.toml and will fetch that compiler version on first build if it is not already installed locally.

Run the full local validation path with:

forge fmt --check
forge build --sizes --skip script
forge test --offline

For focused reviewer-facing validation, use the curated groups below. The fuller local command inventory lives in docs/security-checks.md.

Provenance And AI Assistance

Auralis incorporates and refines selected patterns, utilities, and implementation ideas from earlier private portfolio projects.

The protocol architecture, implementation code, technical decisions, curation of prior work, and final review/integration of changes were directed and owned by me.

AI assistance was used for tests, documentation, scripts, and planning support.
