Asset-backed tokens are becoming a key part of the digital asset landscape. By converting real-world assets like real estate, commodities, and art into blockchain tokens, businesses are unlocking new opportunities for investment and asset management. With tokenized real estate and gold-backed stablecoins gaining momentum, the market for blockchain-based RWAs is expected to reach $16 trillion by 2030. However, as adoption grows, so do the associated risks.
We’ve found some numbers that might shock you,
- $3.8 billion lost to DeFi hacks in 2022 (Chainalysis)

“Security isn’t a feature, it’s the foundation.” — Brian Armstrong, CEO of Coinbase
Unlike traditional cryptocurrencies like Bitcoin or Ethereum, ABTs represent real-world value, which introduces a layer of complexity that standard crypto wallets aren’t designed to handle. Here’s why:
- They require legal enforceability (smart contracts ≠ court-admissible proof)
- They demand regulatory compliance (SEC, MiCA, FATF travel rule)
- They need bulletproof custody (or risk becoming the next Mt. Gox)
Due to these challenges, managing and securing asset-backed tokens is far from straightforward. Without specialized solutions, companies could struggle to meet the expectations of both investors and regulators.
In this blog, we’ll dive into the importance of a secure token custody system and the essential features for its success. As IdeaUsher already has years of experience in developing token custody systems across various industries, we’re well-positioned to guide you through this process, ensuring your tokenized assets are handled with the highest security and compliance standards.
Why a Token Custody System is Critical for Asset-Backed Tokens?
A token custody system is designed to securely store, manage, and protect asset-backed tokens, digital representations of real-world assets such as real estate, commodities, or financial securities. These tokens are different from traditional cryptocurrencies because they are tied to tangible assets, requiring additional security measures, regulatory compliance, and asset verification.
A robust custody system ensures that the tokens remain fully backed by their underlying assets and helps protect investors and issuers from various risks.
Token custody systems include:
- Secure key management: Advanced technologies like multi-signature wallets and multi-party computation are used to protect the private keys associated with tokenized assets.
- Regulatory compliance tools: These systems integrate features like KYC and AML checks to comply with the regulations governing security tokens.
- Asset verification mechanisms: Features like proof-of-reserves and audit trails ensure that the digital tokens are always backed by the corresponding physical assets.
- Insurance and recovery protocols: Custody solutions include plans for key recovery or insurance in case of breaches or technical issues that lead to asset loss.
The Risks of Improper Custody
Without a proper custody system, asset-backed tokens are exposed to several significant risks that could undermine their value and security:
Theft & Hacking
If the private keys controlling the tokens are compromised, attackers can steal or lock assets. This is a real risk, as shown by incidents like the 2022 Ronin Network hack, where $625M was stolen due to insufficient custody controls.
Regulatory Non-Compliance
Different jurisdictions have varying laws governing digital securities. For example, the SEC in the U.S. and MiCA in the EU require that security tokens be stored with qualified custodians. Failing to comply with these rules can result in substantial fines or legal actions that could halt token offerings or trading.
Loss of Investor Trust
Trust is a critical element in financial markets, and a breach of security or non-compliance with regulations can cause a loss of confidence from investors. The collapse of Mt. Gox in 2014 is a notable example, where poor custody practices led to the loss of millions in Bitcoin, significantly hindering its widespread adoption for years.
Examples of Asset-Backed Tokens in Use:
- Real Estate Tokens (e.g., RealT, SolidBlock): Tokenized real estate allows investors to own fractional shares in properties. The custody challenge here lies in ensuring that the deeds are legally recorded and that the tokens remain fully redeemable for the underlying property.
- Precious Metals Tokens (e.g., PAX Gold, Tether Gold): Tokens are backed by physical gold stored in vaults, and the challenge is ensuring regular audits to maintain the 1:1 backing and prevent fraud.
- Art & Collectibles Tokens (e.g., Masterworks, Maecenas): Tokenizing ownership of high-value art allows for greater liquidity. However, ensuring authenticity, preventing fraud, and enabling secure transfers while maintaining value are key challenges.
Regulatory Pressures Demanding Secure Custody
Many regulators worldwide have begun to impose stringent requirements on custodians handling tokenized securities, including:
- SEC Rules (U.S.): Security tokens must be held by qualified custodians under Rule 15c3-3.
- EU’s MiCA: The EU’s Markets in Crypto-Assets regulation requires licensed custodians for asset-backed tokens.
- Switzerland’s DLT Act: Requires institutional-grade custody solutions for tokenized securities under Swiss law.
Failure to comply with these regulations can have serious consequences, such as:
- Legal Penalties: Regulatory authorities may impose fines, sanctions, or even suspend the operation of tokenized securities offerings.
- Exchange Delistings: If qualified custodians do not hold tokens, exchanges may be forced to delist them, preventing institutional investors from accessing these assets.
- Investor Withdrawal: If investors lose confidence due to custody failures or regulatory non-compliance, they may withdraw their investments, damaging the token’s value and market liquidity.
Key Market Takeaways for Token Custody Systems
According to ResearchandMarkets, the crypto custody market is experiencing rapid growth, with projections estimating a rise from $2.92 billion in 2024 to $3.28 billion in 2025. This surge is driven by the expanding demand for asset tokenization, where traditional assets like real estate and commodities are transformed into digital tokens.

As the asset tokenization market itself is set to grow significantly, the need for secure, efficient token custody systems has never been greater.
Token custody systems are critical for safeguarding asset-backed tokens, ensuring security and regulatory compliance. These systems utilize advanced cryptographic techniques, multi-signature wallets, and institutional-grade protocols to offer a secure environment for managing tokenized assets. As more industries adopt tokenization, the demand for these secure systems continues to rise, addressing operational risks and building trust among investors.
Several examples highlight the importance of custody solutions in asset tokenization. Tokenized gold products, like Pax Gold, rely on secure custody infrastructure to ensure that each token is backed by physical gold stored in accredited vaults. In real estate, blockchain-based platforms use tokenization to enable fractional ownership, with institutional custody solutions guaranteeing compliance and asset integrity.
The growing momentum in the market is further demonstrated by strategic investments, such as BlackRock’s $47 million funding in a leading tokenized asset platform.
Key Features of a Secure Token Custody System
Asset-backed tokens represent tangible value, whether it’s real estate, commodities, or securities, and securing these digital assets requires more than just a basic crypto wallet. A secure token custody system must combine military-grade security, regulatory compliance, and operational transparency to protect investors and maintain trust.
Here are the four essential features every custody solution should have:
1. Robust Security Protocols
Military-Grade Encryption & Multi-Signature Wallets
End-to-end encryption protects sensitive data like private keys and transaction details from interception. Multi-Sig wallets require multiple approvals before executing transactions, ensuring that no single party can execute a transaction on their own. Hardware Security Modules ensure that cryptographic keys are stored in tamper-proof environments, significantly boosting security.
Cold Storage & Offline Key Management
Cold storage keeps assets offline, offering protection against online attacks. Sharded key distribution via Multi-Party Computation ensures that no single person has full access to private keys, preventing potential misuse.
Biometric & Two-Factor Authentication
Biometric authentication, such as facial recognition and fingerprint scans, adds an extra layer of security. Time-based one-time passwords enhance protection by preventing unauthorized access to accounts.
In 2023, over $2 billion was stolen from DeFi platforms due to weak custody controls. Proper key management could have prevented most of these breaches.
2. Regulatory Compliance
KYC/AML & Investor Accreditation Checks
Automated identity verification ensures that only eligible investors can hold regulated tokens, while sanctions screening prevents transactions with blacklisted entities. Adherence to global crypto regulations, including the FATF Travel Rule (for cross-border transactions above $1,000) and GDPR (for EU user data protection), is essential for legal compliance.
Adherence to SEC & MiCA Regulations
Custodians must comply with U.S. SEC rules and the EU’s MiCA regulations for tokenized securities, ensuring legal security and regulatory adherence.
Companies like Coinbase Custody and Anchorage Digital obtained federal banking charters to legally custody digital securities, demonstrating the importance of compliance.
3. Transparency and Auditing Capabilities
Smart Contracts for Automated Compliance
Self-executing smart contracts ensure that regulatory rules, like lock-up periods or dividend distributions, are automatically enforced.
Real-time reserve audits, such as Proof-of-Reserves, verify that the digital tokens are always fully backed by their underlying assets.
Immutable Audit Trails
All transactions are recorded on the blockchain, making them tamper-proof. Independent third-party auditors, like Chainalysis or Armanino, help provide objective verification of asset reserves.
4. Scalable Infrastructure
Handling Growth Without Compromising Security
A modular architecture allows for the seamless addition of new assets, such as tokenized stocks or bonds, while maintaining the security of existing assets. Support for high-throughput blockchains, like Ethereum L2s or Polkadot, ensures low latency and scalability as tokenized assets grow.
Third-Party Integrations for Trust
Trusted insurance providers, such as Lloyd’s of London, cover the risk of asset theft or loss. Leading audit firms like Deloitte and PwC validate asset reserves, further enhancing trust in the custody solution

The Future of Tokenized Asset Custody: Trends & Opportunities
The tokenization of RWAs is rapidly growing, with predictions placing the market at $16 trillion by 2030, according to Boston Consulting Group. As adoption increases, so does the demand for next-generation token custody solutions that balance security, compliance, and scalability.
Here’s a look at the trends shaping the future of token custody systems and how innovative platforms can stay ahead of the curve.
1. Decentralized Custody (DeFi-Native Solutions)
Decentralized custody allows users to retain control over their assets while ensuring compliance with regulations. Non-custodial wallets, like MetaMask Institutional, are gaining popularity for institutional investors. Additionally, technologies like MPC and Threshold Signatures remove single points of failure without relying on a central custodian.
DAOs are also being used to manage treasuries, offering collective governance over asset-backed tokens.
For example, Fireblocks’ DeFi custody solution enables institutional participation in DeFi while mitigating risks tied to smart contracts.
2. Hybrid Custody (Blending CeFi & DeFi)
Hybrid custody models combine the best of CeFi and DeFi. These solutions feature smart contract-controlled vaults that regulated custodians oversee. Additionally, permissioned DeFi pools ensure that only KYC-verified users can access tokenized assets, providing a bridge between the flexibility of blockchain and traditional financial security.
Why It Matters: Hybrid models appeal to traditional investors who seek the efficiency of blockchain technology without fully embracing the risks associated with decentralization.
3. Institutional-Grade Custody Systems
Institutional-grade custody solutions are evolving to address future risks and regulatory demands. Key features include quantum-resistant encryption to protect against future hacking threats and interoperable custody networks like Polkadot’s XCM, which enable cross-chain asset transfers.
These systems also cater to tokenized securities, ensuring compliance with regulations like MiCA, SEC Rule 15c3-3, and the EU’s DLT Pilot Regime.
For example, Northern Trust has developed a digital asset custody platform that meets both SEC and EU regulatory standards, effectively bridging traditional finance and crypto.
