Security and Storage

Holos enforces strict standards in asset custody, NFT management, and user asset protection.

Secure Custody

• Assets are stored in dedicated warehouses operated by leading Japanese card shops. The majority of our trading card assets are securely stored within the facilities of one of Japan's most reputable trading card specialists. In addition, particularly rare and high value cards are kept in a dedicated vault operated by TERRADA Warehouse, an institution globally recognized for its expertise in the storage of fine art. TERADA Warehouse provides world class standards in security and privacy protection. By combining multiple storage solutions including professional vaults, we ensure the integrity and safety of all assets under our care.

• All assets are appraised and verified before storage.

• Only inventory directly acquired by Holos is eligible for NFT issuance.

This eliminates the risks of fake or non-existent NFTs.

Non-Custodial Wallet Management

• Users store NFTs in their own wallets (e.g., MetaMask)

• Holos does not retain user funds or private keys

• Even if Holos is offline, NFTs remain in the user’s control

Adheres to Web3 principles of self-sovereign asset management.

Polygon Blockchain Infrastructure

• NFT issuance and Burns are executed on the Polygon network

• Polygon is a trusted Ethereum Layer 2 with low gas fees and high speed

• Built on a framework proven in over 4.4 million transactions

• Smart contracts are verified and security-audited

Provides transparency, resilience, efficiency, and scalability.

User Assets Are Never Held by Holos

• Holos never stores NFTs or wallets on behalf of users

• Eliminates centralized points of failure

• Ensures that hacking Holos cannot compromise user funds

This reflects the platform’s commitment to decentralized security philosophy.
