Liminal Cold Wallets and Smart Wallet Refill Solutions

Enterprise-level secure crypto walltes storage and management solutions provider, Liminal is creating innovative, state-of-the-art blockchain products. With its main focus on crypto businesses of all sizes, family offices, and even individuals whose lives and savings revolve around extensive dealings in crypto assets, Liminal has introduced multiple interconnected crypto wallet infrastructure solutions with standalone operation capabilities. The first two among the lot are Liminal Cold wallets and Liminal Smart Wallet Refill solutions.

Crypto platforms can either choose to implement any of the available Liminal solutions depending on specific requirements or use the entire suite for all-around security and safe management of assets. Liminal Cold Wallets and Smart Wallet Refill solutions, together, make up the majority of the enterprise wallet infrastructure. To understand better, let us take a look at a conventional enterprise wallet infrastructure commonly implemented by crypto exchanges and other platforms.

Conventional Enterprise Wallet Infrastructure

Every crypto business needs to consider the safety of its crypto assets; as a result, they use a combination of different wallets to optimize security while maintaining operational convenience. A standard enterprise wallet infrastructure includes a cold wallet where the majority of the funds are stored; an always-online hot wallet with just enough funds to meet immediate requirements, and an intermediary warm wallet receiving reserve funds from the cold wallet to refill the hot wallets as and when they run low on funds. A dedicated wallet refill team with access to the warm wallets keeps track of hot wallets and initiates refills whenever the crypto asset levels in them go below a fixed threshold limit. Most enterprises generally maintain their cold wallets on air-gapped machines or use software multisig or MPC-based cold wallet solutions with access to these wallets limited to one or few handpicked top-level executives of the organization.

The conventional process is time and resource-intensive, requiring round-the-clock monitoring and inefficient key management where wallet keys are shared with multiple people just to ensure uninterrupted operations. All these factors introduce vulnerabilities to the wallet infrastructure, exposing the company’s crypto assets to various risks, including hacking attacks, theft, and misuse of keys, and unauthorized transactions. At the same time, proprietary MPC-based cold wallet solutions don’t come cheap and create excessive dependence on the solutions provider regarding troubleshooting, key management, and recovery.

Liminal’s Enterprise Wallet Solution to the Rescue

Liminal’s suite of enterprise crypto asset management solutions addresses the shortcomings of existing wallet infrastructure. The Liminal Smart Cold Wallets, along with the Smart Wallet Refill solution, create an end-to-end secure channel for high-value crypto transactions within the platform’s infrastructure.

Liminal Smart Cold Wallets

Liminal Cold Wallets is a secure, HSM-based multisig cold wallet infrastructure with multiple built-in security and failsafe features. The implementation of tried and tested hardware wallet-only multisig wallet solution instead of the more popular MPC or software multisig option combined with KYC-backed, customizable Policy Shield allows users to implement their desired transaction parameters without compromising the safety of their assets. Further, Liminal’s Cold Wallet solution virtually eliminates the chances of users executing transactions to a wrong address, either deliberately or by mistake, with the help of its wallet whitelisting feature. But that’s not all, as Liminal Signer acts as the final line of defense by retaining the final signing authority to initiate any outgoing transaction from the cold wallets upon satisfactory verification of compliance requirements per user-dictated policies.

Using Smart Cold Wallets, crypto platforms can easily replenish their warm wallets or transfer funds to other addresses in a few simple steps without worrying about possible security risks.

Liminal Smart Wallet Refill

With assets safely transferred from the cold wallet to the warm wallet, the next task is to secure the hot wallet refill process. The Smart Wallet Refill solution takes care of the subsequent steps by allowing the wallet teams to automate the wallet refill process by programming the applicable refill policies. Each Smart Refill Wallet acts as a warm wallet, receiving funds from the cold wallet and disbursing it to the hot wallets whenever the requirement arises.

Like the Liminal Cold Wallets, the Smart Refill Wallet responsible for initiating refill transactions are multisig in nature. The number of required signatures for refill transactions will be decided by the client, with Liminal Signer being one of the final signatories. To ensure uninterrupted operation, the Smart Refill Wallets secure batches of partially signed transactions from all the assigned participants, allowing Liminal Signer to place the last signature to process refill transactions once the conditions as per refill policy are met.

The client-provided parameters considered by the Smart Refill Wallets to replenish hot wallets include the transaction size, whitelisted wallet address, trigger amount in the hot wallet to initiate refill, cooldown period after each transaction, and more. In addition, the solution also makes allowance for manual intervention to trigger one-time refill transactions if the need arises during the cooldown period. The right implementation of the Smart Wallet Refill solution removes the need for a large, dedicated team just for monitoring and refilling hot wallets, allowing efficient allocation of manpower throughout the organization.

Operating Smart Cold Wallets and Smart Wallet Refill Solutions in Synchrony

Both solutions singlehandedly strengthen the wallet infrastructure and streamline operations to a great extent. Implementing them together can potentially make a huge difference in the way wallets are managed within the organization.

Working in tandem, both solutions will allow organizations to manage the bulk of their funds in a secure ecosystem with inbuilt redundancies. While the Smart Cold Wallets ensures a convenient and safe execution of outbound transactions without compromising the integrity of critical private keys, the Smart Wallet Refill safeguards significant volumes of transactions downstream by minimizing human intervention in the hot wallet refill process.

In other words, implementing Liminal’s solutions such that the outward transaction from the Smart Cold Wallets is sent to the Smart Refill Wallet to be further transferred to hot wallets will significantly improve the overall security standards of the platform’s wallet infrastructure.

A Lot More to Come

The Smart Cold Wallets and Smart Wallet Refills are just two of Liminal’s many products as part of its all-around crypto asset custody and management solutions. More products for enhanced security and convenience will be revealed soon.

More on Crypto

As we continue constructing a fully regulated digital asset custody platform, ensuring secure storage for both crypto and fiat assets remains a critical priority. 

To facilitate the last checkpoint of enabling institutions to convert their digital asset treasury into fiat currency, we’re expanding beyond pure wallet infrastructure and integrating seamless fiat off-ramp capabilities for our partners.

We’re thrilled to announce our partnership with Encryptus, licensed and compliant off-ramp solutions tailored for institutional clients. This collaboration elevates Liminal’s service offerings by empowering our partners to convert their digital asset treasuries into fiat currencies efficiently.

Integrating A Seamless Off-Ramp Solution

January 22, 2024

Hello world, it’s that time of the month when we share the biggest security breaches in the world of Web3 through our Security and Regulatory Newsletter. 

Liminal believes in optimizing security and custody practices globally across the Web3 industry. Through our Newsletter, we highlight security, regulations, and compliance incidents that have happened in the past month and how one can follow better Security practices to safeguard their digital assets. 

We will also highlight regulatory changes that might have happened globally, which were significant to the overall ecosystem.

Dive in and get a detailed analysis of everything security and regulation in the domain of web3 with Liminal’s Monthly Security and Regulatory Newsletter.

Web3 Security Compromises in January

Abracadabra exploited for almost $6.5 million, Magic Internet Money stablecoin depegs

The Magic Internet Money ($MIM) stablecoin has lost its dollar peg again, dipping all the way below $0.77 in a flash crash before returning to around $0.95.

The depeg appears to be related to an exploit of the Abracadabra lending protocol, which allows people to borrow $MIM. An attacker exploited an apparent flaw in the platform’s smart contracts to drain around $6.5 million.

Goledo Finance hacked for $1.7 million

Goledo Finance, an Aave-based lending protocol, was exploited through a flash loan attack. The attacker stole assets estimated by CertiK to be around $1.7 million.

Goledo Finance contacted the attacker to offer a 10% “bounty” for the return of the remaining assets. In a message on January 29, the attacker wrote: “I hacked Goledo and want to negotiate.”

Socket service and its Bungee bridge suffer $3.3 million theft

The Socket cross-chain infrastructure protocol was hacked for around $3.3 million in an attack that exploited its Bungee bridge. The thieves were able to exploit a bug that allowed them to take assets from those who had approved a portion of the system called SocketGateway.

A little over 700 victims were affected, and the highest loss from a single wallet was around $657,000. 121 wallets lost assets priced at more than $10,000.

On January 23, the protocol announced they had recovered 1,032 ETH (~$2.23 million) of the stolen funds.

Web3 Regulatory Practices for January

The EU Imposes Stricter Due Diligence Rules for Crypto Firms

On Jan. 17, the European Council and the Parliament came to a provisional agreement on parts of the Anti-Money Laundering Regulation (AMLR) that now extends to the crypto sector.

Under the new rules, cryptocurrency firms will be required to run due diligence on their customers involving a transaction amounting to €1,000 ($1,090) or more. 

However, the agreement isn’t final yet as it has to be first officially adopted by the Council and Parliament before the rules can be applied.

So, after the EU passed its landmark MiCA regulation last year, which clarified rules about cryptocurrencies, regulators are now targeting the space with tighter controls. 

While these regulations bolster security and trust in the crypto market, potentially attracting more cautious investors and combating financial crimes, they also present challenges. 

The US State of Virginia Introduces Digital Assets Mining Rights

Recently, the Virginia State Senate introduced Bill No. 339, which outlines regulations for the transactions and mining of digital assets and their treatment under tax laws. 

The legislation exempts individuals and businesses engaged in crypto mining activities from obtaining money transmitter licenses. Additionally, it protects miners from any discrimination. 

Issuers and sellers of crypto are also exempted from securities registration requirements if certain conditions are met. Moreover, those offering mining or staking services are not to be classified as “financial investment” but must file a notice to qualify for the exemption.

The bill further incentivizes crypto’s use for everyday transactions by offering tax benefits. Under this, up to $200 per transaction can be excluded from an individual’s net capital gains or gains derived from using crypto to purchase goods or services, starting from Jan. 1, 2024.

Key Takeaways:

  • Hackers continue to exploit vulnerabilities in DeFi protocols and cross-chain bridges, highlighting the need for robust security measures.
  • Regulatory frameworks are evolving rapidly, with stricter AML rules and supportive legislation for emerging technologies like crypto mining.
  • Staying informed about these developments is crucial for navigating the digital assets market safely and responsibly.

Stay #LiminalSecure

These events highlight the constant evolution of Web3 security and regulation. You can confidently navigate this dynamic landscape by staying informed and prioritizing security best practices. 

At Liminal, we’re committed to empowering institutions to unlock the full potential of digital assets without compromising security or compliance norms with our robust custody and wallet infrastructure solutions. Join us on this journey towards a safer, more accessible future for digital assets.

January 15, 2024

Buckle up as we’re about to take a trip down memory lane. 

The year 2023 was a wild ride that showed signs of a plummeting market, groundbreaking innovation and regulatory hurdles. 

Contrastingly, in the same year, we saw no market-shattering crashes. Financial institutions extending an olive branch, key jurisdictions unlocking the doors to blockchain technology. 

Simultaneously, at Liminal, we experienced significant breakthroughs, re-engineering our positioning and becoming a pioneer in digital asset security with bank-grade custody. 

We took major strides this year, right from building comprehensive products to becoming a qualified custodian, from revamping our brand design to expanding our offices in newer locations, from partnering with hyper-local communities to onboarding a diverse set of clients,  we did it all. 

So, let us take you through everything we accomplished in 2023 and what the future holds.  

Liminal Became A Qualified Custodian

One of the prominent moves we made this year was to change our positioning as a regulated custodian from being a wallet infrastructure platform. 

We got two licenses in key jurisdictions to operate as a regulated custodian. 

The first one came from Hong Kong, where we acquired the TCSP license issued by the SFC, which oversees and regulates financial activities to ensure compliance with legal and regulatory obligations. 

Our next license came in the MENA region, where we got In-Principle Approval for the FSP license granted by the FSRA, a governing body in ADGM, to establish a progressive financial services environment. 

Both these licenses paved the way for Liminal to push its wallet infrastructure and offer bank-grade custody to institutions looking to operate in these particular regions. 

Liminal Introduced A Suite of Products & Features

Continuing our building spree, we launched new products and integrations to broaden the existing infrastructure and added more parameters of security, scalability and sustainability. 

Staking-as-a-Service

Liminal launched staking for institutions to eliminate the risks involved in running staking nodes and the vulnerabilities in hot wallet transfer. 

Hence, we introduced an industry-first mechanism of cold wallet staking to ease staking for institutions and secure assets explicitly.  

Whitelabel Solution

Accelerating the go-to-market time for organisations looking to build a secure and customisable application, Liminal launched its whitelabel solutions

Targeted to help organisations meet security standards, manage assets with maximum control, and add their custom branding to give it a personal touch. Our whitelabel solution is a first-in-class custodian-developed solution for institutional grade custody.

Smart Consolidation

We are building not just secure custody but also automation-based features to eliminate manual errors, increase the throughput of transactions and scale institutional wallets. 

Taking this ahead, we launched the Smart Consolidation feature to automatically calculate all the active addresses and consolidate them into a single address. With this level of automation, managing multiple addresses becomes uber easy for wallet teams. 

Travel Rule 

To limit the use of cryptocurrencies for activities like money laundering and terror financing by regulatory bodies, travel rule was mandated for institutions to follow. 

Continuing the latest compliance integration policy, Liminal partnered with Notabene to introduce Travel Rule, enabling institutions to manage counter-party risk and extend the process of due diligence right from the Vaults dashboard.   

Liminal Accured List Of Security Certifications

Following our ISO certification for data privacy and risk management, we added two new security certifications to fortify our systems and build trust for our clients. 

Liminal Achieves Crypto’s Highest Security Mark: CCSS Level-3 Certified

Cryptocurrency security lacked a gold standard, creating a vulnerable ecosystem. Enter the CryptoCurrency Security Standard (CCSS), setting the bar for auditing and certifying custodian infrastructure and establishing levels of trust and confidence for investors. 

Liminal became only the second wallet infra platform and the first regulated custodian to be accredited with Level-3 certification, deeming wallets, transfer environments, workflows and engines safe and secure. 

Liminal Reciueved SOC 2 Type II Certification

To tackle threats in institutional-grade security, organisations’ SOC has been identified as the primitive compliance standard for service organisations to handle customer data.

Liminal successfully attained SOC 2 Type II certification, validating its setup of security controls & compliance processes to be industry standard. 

Liminal Level Up

Liminal unveiled its most significant platform upgrade ever, revolutionising the future design standard of a qualified custodian. This level-up activity included revamping our website and product UI, giving a completely new look and feel to not “Liminal” but “Liminal Custody”. 

The Liminal level-up activity was a strategic step and the biggest one for us this year to create an intuitive, inviting and tailored experience for our clients. 

Liminal Reached New Borders

We spread out our operations this year, reaching new borders and onboarding a new wave of institutions across gaming, DeFi, HNI wealth, treasuries, and exchanges! From Indonesia and Africa to India, UAE, and Korea, we are setting up custody operations worldwide. 

This isn’t just a roster of clients; it’s a network ready to spark connections, collaborations, and shared success to further the definition of secure assets. 

Liminal Collaborated With Law Enforcement Agencies

The best and the proudest moment of Liminal for this year was when we collaborated with CBI & Himachal Prashesh police department to aid them in seizing digital assets. 

This partnership put us on the map, as we became the first point of contact for LEAs in India, and we standardised the process of secure seizure of digital assets. Leveraging our expertise, we enabled a safe space for officers to learn the basics of custody, contributing to a safer digital landscape.

Team Liminal Grew Bigger

Building such a massive infrastructure, prioritising security and compliance over everything else, we had to grow the team to build at pace and expand at an even higher level. Not only did we grow in team numbers, but we also elongated our footprint to new destinations. 

Team Liminal went from 32 to 70 with 5 new offices in Mumbai, Ahmedabad, Hong Kong, Singapore and ADGM, setting up our custody operations steadfastly. 

What’s To Look Out For In 2024

We are excited to announce that our commitment to integrating the most secure digital asset wallets with a cutting-edge custody platform is swiftly becoming a reality. 

The upcoming year, 2024, will serve as a testament to this transformative journey. Moving beyond self-custody, we are constructing a comprehensive infrastructure encompassing both custodial and non-custodial wallets. Exciting products are set to launch starting from the first week of January, some of which are: 

  • Official Custody Platform Launch
  • Liminal’s Off-Exchange Settlement Hub
  • Secure Custody of Real-World ‘Tokenised’ Asset

The Web3 space has evolved explicitly this year, pushing the narrative of secure digital asset custody and security, introducing new regulations and compliance standards, licensing VASP providers and standardising the use of custodians as a trusted third party. 

At Liminal, we took major strides this year, from building comprehensive products to becoming a regulated custodian, from revamping our brand design to building the full infrastructure of custodial and non-custodial wallets.
