Arch Lending: Building Crypto-Backed Loans Around Security, Custody and Flexibility
For crypto investors who have spent years accumulating digital assets, one of the hardest financial decisions is also one of the simplest: what happens when you need cash? Selling can create a taxable event, reduce exposure to an asset you may expect to appreciate, and permanently shrink the position you worked to build. Borrowing against crypto offers another option—but it introduces a completely different set of questions. Who controls the collateral? Is it being lent to somebody else? At what point can it be liquidated? How quickly can a borrower respond to a falling market? And perhaps most importantly after the failures of several major crypto lenders: what happens to the collateral if something goes wrong with the lender itself? Those are exactly the questions that have shaped Arch Lending. Founded in February 2022 by Dhruv Patel and Himanshu Sahay, Arch entered crypto lending at almost the worst—or perhaps the most instructive—possible moment. The company was born just as the digital-asset lending industry was heading toward one of the most difficult periods in its history. Instead of retreating from that environment, Arch built its model around lessons learned from it. Today, the company offers overcollateralized loans against Bitcoin, Ethereum, Solana and XRP, along with newer lending options involving tokenized gold. Its platform emphasizes qualified custody, no rehypothecation, defined liquidation thresholds and direct human support. For borrowers comparing crypto-backed lenders, that makes Arch worth understanding. Born During Crypto Lending’s Most Difficult Period Arch was founded by crypto investors who say they were frustrated by the lack of financial services designed for people whose wealth increasingly existed outside traditional stocks, bonds and bank accounts. Patel, Arch’s co-founder and CEO, previously worked at Brex building financial products for businesses. Co-founder Himanshu Sahay brought an engineering and technology background that included Snapchat, Tinder and Bird. Arch says the founders’ goal was to combine financial infrastructure with the type of user experience consumers had come to expect from modern technology companies. The timing was significant. Arch was founded in February 2022. Over the months that followed, the crypto industry experienced the collapses of Terra, Celsius, Voyager, BlockFi, FTX and other companies or projects that damaged confidence in centralized crypto finance. One of the biggest lessons from that period was that borrowers needed to understand more than an advertised interest rate. They needed to know what happened to their collateral after they deposited it. Arch increasingly made that question central to its lending model. The company initially raised $2.75 million while developing its alternative-asset lending platform. By August 2024, Arch announced another $75 million consisting of an oversubscribed $5 million equity round and a $70 million loan-financing facility supplied by Galaxy. Investors in the company have included Morgan Creek Digital, Castle Island Ventures, Galaxy Ventures and BitGo Ventures. That funding gave Arch additional lending capacity, but its most important differentiator for borrowers may be what it says it doesn’t do with collateral. No Rehypothecation Rehypothecation sounds technical, but every crypto borrower should understand it before taking out a loan. When collateral is rehypothecated, a lender may take assets pledged by its customers and lend, invest or otherwise deploy those assets elsewhere. That can create another layer of counterparty risk. Arch says it follows a strict zero-rehypothecation policy. According to Arch, collateral is not lent out, traded, staked or otherwise deployed to generate additional revenue. Instead, pledged assets remain in custody supporting the borrower’s loan. That distinction matters. A borrower should never assume that depositing Bitcoin with two different lenders creates the same risk simply because both loans have the same LTV or interest rate. CryptoLoanAdvisor believes custody structure and rehypothecation policy should be examined alongside APR when comparing lenders. Anchorage Digital Holds the Collateral Arch currently uses Anchorage Digital Bank as its qualified custodian. Anchorage Digital is a federally chartered digital-asset bank regulated by the Office of the Comptroller of the Currency. Arch says collateral is maintained under segregated custody and structured to be bankruptcy-remote from Arch’s corporate assets. Arch also states that Anchorage maintains $100 million in Lloyd’s of London insurance coverage covering specified risks, subject to the policy’s terms and exclusions. For loans above $100,000, Arch says segregated wallets can be made available, along with blockchain explorer links allowing borrowers to verify the location of their collateral on-chain. Arch itself does not hold the private keys. That structure addresses one of the most important questions CLA believes every borrower should ask: Who actually controls my crypto while the loan is outstanding? BTC, ETH, SOL and XRP Arch’s standard crypto-backed lending platform currently supports four major digital assets: Bitcoin (BTC)Ethereum (ETH)Solana (SOL)XRP The company’s latest published loan terms show that these assets do not receive identical LTV treatment. Bitcoin currently has the highest standard starting LTV: BTC: 60% starting LTV, 70% margin call and 80% partial-liquidation level. Ethereum is slightly more conservative: ETH: 55% starting LTV, 65% margin call and 75% partial liquidation. Solana and XRP carry lower starting thresholds: SOL: 45% starting LTV, 55% margin call and 65% partial liquidation. XRP: 45% starting LTV, 55% margin call and 65% partial liquidation. That difference is important. A borrower pledging $100,000 worth of Bitcoin should not assume the same borrowing capacity applies to $100,000 of XRP or Solana. The asset being pledged directly affects the safety buffer between the initial loan and a margin call. Arch Uses Partial Liquidation One of the more borrower-friendly features of Arch’s structure is its approach to liquidation. If collateral values fall far enough, liquidation remains a real risk. A crypto-backed loan does not eliminate volatility simply because the borrower didn’t sell the crypto when taking out the loan. Arch uses warning levels, margin-call levels and partial-liquidation thresholds. Using Bitcoin as an example, the company currently considers an LTV of 60% or below healthy. At 65%, the borrower receives a warning. At 70%, a margin call is triggered and the borrower generally has 24 hours to add collateral or repay part of the loan. At 80%, Arch may partially liquidate
