# Showcase Research Summary

Collected on 2026-06-08.

## Strongest Feature Candidates

### Moonbeam

Production EVM-compatible Polkadot parachain. Best for showing long-running protocol stewardship, runtime upgrades, EVM compatibility, XCM interoperability, benchmarking, governance, and Substrate operations.

Useful signals:
- Polkadot launch completed on 2022-01-11.
- Public repo remains active.
- GitHub snapshot: 938 stars, 382 forks, latest release v0.52.2 on 2026-06-04.

### DataHaven / StorageHub

Best for showing storage infrastructure, AI-era data workloads, EVM-compatible Substrate chains, relayers, SDKs, and Ethereum-aligned security.

Useful signals:
- DataHaven testnet launch reported internally as 2025-12-17.
- GitHub snapshot: datahaven-xyz/datahaven has 7952 stars and release v0.26.0 on 2026-03-12.
- StorageHub was publicly introduced by Web3 Foundation as a Moonsong Labs Decentralized Futures grantee.
- Caveat: DataHaven should be framed as shipped/archival because the public site currently signals wind-down.

### Foundry-zksync and anvil-zksync

Best for showing developer tooling depth for ZKsync: compiler integration, EraVM local testing, RPC compatibility, transaction tracing, deployment, simulation, and paymaster/account-abstraction workflows.

Useful signals:
- Foundry-zksync GitHub snapshot: 387 stars, 175 forks, release foundry-zksync-v0.1.9 on 2026-02-24.
- anvil-zksync GitHub snapshot: 322 stars, 89 forks, release v0.6.11 on 2025-10-08.
- Foundry-zksync case study notes ecosystem usage by Aave, EtherFi, Abstract, Lens, Frax, and Sophon.

### ZKsync Governance App

Best for showing governance, upgrade coordination, Safe/EOA signing flows, and verification tooling.

Useful signals:
- ZK Nation explicitly says Moonsong Labs built GovAuth and the Upgrade Verification Tool.
- Covers standard upgrades, emergency upgrades, freezes/unfreezes, vetoes, role-based actions, and bytecode/storage verification.

### ZKsync SSO Account Recovery

Best for showing ZK circuits, OIDC/JWT verification, guardian recovery, account abstraction, passkeys, and audit maturity.

Useful signals:
- OpenZeppelin audited Moonsong-Labs/zksync-social-login-circuit; all 9 findings resolved.
- Related audit coverage exists for OIDC recovery and guardian recovery validators.

### Perena Solana Metavaults

Best for showing Solana DeFi, Anchor, dynamic adapters, atomic transaction composition, SDKs, instant withdrawals, adaptive fees, and circuit breakers.

Useful signals:
- Moonsong case study and Perena docs validate the vault adapter architecture.
- Internal Notion includes multiple related vault proposal pages.

### Solana Subscriptions / Multi-Delegate

Best for showing Solana payment infrastructure and mainnet delivery.

Useful signals:
- Solana and Moonsong posts describe the infrastructure.
- Open-source repo from Solana Foundation.
- Mainnet, audited, SPL Token and Token-2022 support.

## Secondary / Review Before Prominent Use

- `tradable`: Strong client/product evidence around $1.7B tokenized private credit on ZKsync, but public Moonsong attribution was not found.
- `gold-market-ubs`: Strong public UBS/ZKsync Validium PoC evidence, but public Moonsong attribution was not found.
- `glacis`: Strong public Glacis cross-chain evidence, but specific Solana xERC20 PoC evidence is internal.
- `theoriq`: Good AI DeFi and repo evidence, but specific Hyperliquid implementation evidence is not public.
- `substrate-mcp`: Repo and internal story exist; public narrative evidence is thin.
