BlockFi vs Radiant Capital

During active operation, BlockFi established a comprehensive retail financial suite anchored by the BlockFi Interest Account (BIA). This yield program supported established digital assets including Bitcoin, Ethereum, Litecoin, and Paxos Gold, alongside major USD-pegged stablecoins such as USDC, GUSD, and USDT. Yields were generated by pooling customer deposits and lending them to institutional trading desks, market makers, and corporate borrowers at negotiated interest rates. The platform displayed accrued yields daily and distributed compounding monthly payouts denominated either in-kind or in an alternate supported asset through an automated flex-payment setting.

Complementing its interest accounts, BlockFi operated a spot trading interface that enabled frictionless asset swaps directly inside the client dashboard. The ecosystem also introduced fiat-denominated personal loans secured by digital collateral, requiring initial loan-to-value ratios ranging from twenty to fifty percent. Later in its operational lifecycle, BlockFi introduced an uncollateralized credit card program featuring flat Bitcoin rewards on consumer purchases, positioning the platform as an integrated consumer banking alternative for digital asset holders. All active retail operations, account originations, trading desks, and lending facilities remain permanently closed.

Radiant Capital operates as a decentralized, non-custodial money market that leverages LayerZero messaging formats to facilitate omnichain borrowing. Instead of restricting collateral and loan origination to a single isolated network, Radiant enables a user to deposit a supported blue-chip token on one chain, such as Arbitrum, and borrow an entirely different asset on another network, like Ethereum mainnet or BNB Chain. This architecture aims to reduce the friction, execution delays, and bridge wrapping steps typically associated with moving assets manually between separate decentralized finance ecosystems.

The asset catalog focuses primarily on high-liquidity foundational tokens. Supported collateral and borrowable assets commonly include stablecoins such as USDC, USDT, and DAI, alongside major cryptocurrencies including wrapped Bitcoin, wrapped Ethereum, and native network tokens. Each asset pool operates with distinct risk parameters, loan to value ratios, and liquidation thresholds determined by governance models. The primary utility and governance asset, RDNT, functions alongside the core money markets to distribute protocol fee shares to users who lock dynamic liquidity pairs, establishing an incentive layer that supplements standard pool utilization interest.

BlockFi maintained a variable cost structure that eliminated direct deposit fees while capturing revenue through trading spreads, loan origination charges, and withdrawal thresholds. Spot trading did not charge explicit commission line items; instead, trade costs were incorporated into proprietary market spreads, which typically ranged between one and two percent depending on prevailing exchange liquidity. Borrowers seeking USD liquidity faced tiered interest rates based on chosen collateralization levels, alongside nominal loan origination fees deducted directly from total disbursed capital.

For withdrawals, BlockFi historically offered account holders one complimentary fiat or crypto withdrawal per calendar month for selected primary assets, after which flat blockchain processing fees applied. Crypto transfers were subject to strict administrative security holds, requiring mandatory manual review windows that extended delivery timelines by twenty-four to forty-eight business hours. Following the operational pause and subsequent bankruptcy filing in late 2022, routine withdrawal mechanics were suspended, shifting all remaining capital distributions to formal bankruptcy estate distribution schedules handled by court-appointed restructuring agents and digital claim portals.

Fees on Radiant Capital are fundamentally algorithmic, reflecting real-time supply and demand dynamics across individual asset pools. Suppliers earn variable interest rates driven by pool utilization, meaning rates rise automatically as borrowing demand increases. Borrowers pay variable interest rates corresponding to the utilization curve of the borrowed pool. In addition to variable base interest rates, transactions on Radiant require native blockchain gas fees on the originating and destination chains to execute smart contract operations and LayerZero cross-chain messages.

To access RDNT emission rewards and receive a share of protocol platform fees, participants must interact with the Dynamic Liquidity Provision mechanism. Users lock liquidity pool tokens, typically RDNT paired with ETH or BNB, representing at least a specified percentage of their total supplied collateral value. Protocol revenue generated from borrower interest and liquidation penalties is distributed to eligible locked liquidity providers in primary assets like stablecoins and native tokens. Withdrawing supplied liquidity remains non-custodial and flexible, provided the user maintains an account health factor safely above the liquidation threshold, while locked liquidity tokens remain subject to predefined vesting and locking terms.

BlockFi utilized a centralized, third-party custodial framework rather than maintaining direct internal cold-storage infrastructure. Primary custodial operations were handled by institutional partners such as Gemini Trust Company, BitGo, and other regulated trust entities. While custodial reserves for simple wallet balances were segregated, digital assets deposited into the BlockFi Interest Account were explicitly rehypothecated. Under platform terms of service, deposited funds were unsegregated and transferred directly to institutional borrowers, creating unsecured creditor exposure for retail account holders.

From a software and operational interface perspective, BlockFi implemented standard consumer defense protocols. User accounts featured mandatory two-factor authentication via authenticator apps, automated login notifications, biometric authentication on mobile devices, and an address allowlisting tool known as crypto address whitelisting. The whitelisting control imposed a mandatory seven-day delay whenever users added or modified external withdrawal destinations, protecting accounts against immediate unauthorized fund drains during credential compromise. Nevertheless, consumer-facing account security controls could not mitigate the structural balance-sheet default risks inherent in institutional lending activities.

Because Radiant Capital is an autonomous decentralized finance protocol, custody of deposited funds remains governed entirely by smart contracts rather than a centralized intermediary. Users retain self-custody through their connected Web3 wallets, interacting directly with open-source smart contract pools. The protocol relies heavily on LayerZero omnichain messaging contracts to track balances, collateral ratios, and cross-chain execution states. This multi-layered architecture introduces composite risk, as security depends not only on Radiant core contracts but also on external bridging infrastructure and network oracles.

To manage operational risk, Radiant implements automated liquidation mechanisms supported by third-party price oracles like Chainlink. When collateral values drop or accrued interest pushes an account health factor below the liquidation threshold of 1.0, external liquidators can repay a portion of the notable debt in exchange for seized collateral at a liquidation penalty discount. Users must proactively monitor collateral ratios through self-directed controls and alerts, particularly during periods of steep market volatility. Smart contracts undergo external security reviews, yet interaction inherently involves risk exposure to potential software bugs, oracle latency, and cross-chain messaging vulnerabilities.

BlockFi operated out of the United States under state-level money transmitter licensing frameworks, catering to an international user base across more than one hundred countries before entering regulatory restrictions. In February 2022, the platform reached a landmark one-hundred-million-dollar settlement with the U.S. Securities and Exchange Commission and state regulators, which determined that interest accounts constituted unregistered securities. As a consequence, BlockFi was ordered to halt onboarding new U.S. retail customers into yield accounts and began preparations to register a replacement yield product, BlockFi Yield, which never completed regulatory approval.

Customer support channels transitioned completely following the Chapter 11 filing. Historical live chat, phone support, and ticket desks were phased out in favor of standardized bankruptcy claims administration administered by Kroll Restructuring Administration. Former clients track estate reconciliations, distribution timelines, and asset recovery percentages strictly through official court filings and dedicated claim portals. Active onboarding, technical account assistance, and retail client services are entirely discontinued, with corporate operations existing solely to finalize estate liquidation and authorized creditor repayments.

Access to Radiant Capital is permissionless at the smart contract level, enabling users globally to connect compatible Web3 wallets directly to the decentralized application. However, the user interface hosted on web domains may apply geographic restrictions or screening policies to comply with regulatory standards across specific jurisdictions. Users are solely responsible for ensuring that their use of decentralized lending products aligns with local financial laws, tax reporting mandates, and token trading regulations in their home region.

Customer support on Radiant follows standard decentralized finance conventions, functioning primarily through community-driven channels rather than dedicated enterprise help desks. Assistance is available through structured documentation, community forums, and official communication platforms such as Discord. Because the protocol is autonomous and non-custodial, support staff and community moderators cannot intervene in transactions, reverse failed transfers, recover lost private keys, or alter liquidation outcomes. Users are expected to maintain technical proficiency regarding transaction signing, gas estimation, slippage tolerances, and self-custody wallet management before executing complex omnichain loan positions.

The core vulnerability in the BlockFi business architecture stemmed from rehypothecation, where customer funds deposited into interest accounts were uncollateralized at the customer level and lent out to third-party institutions. When severe market stress caused major institutional borrowers and affiliated exchanges to fail, BlockFi suffered severe collateral deficits that made honoring consumer redemptions mathematically impossible. Crypto deposited on centralized lending platforms does not benefit from statutory protections like FDIC insurance or SIPC coverage, meaning customer balances are classified as general unsecured claims during corporate insolvency.

While custodial wallet accounts without yield functionality were eventually treated under separate court rulings due to their non-rehypothecated structure, interest account users faced extended recovery timelines and fractional repayments dependent on estate recoveries from other defunct entities. This dynamic underscores the critical distinction between pure custody and yield-bearing financial accounts in digital asset markets, where stated yields directly reflect default risk.

Participating in cross-chain money markets involves distinct risk layers beyond standard single-chain decentralized lending. Radiant Capital interacts with cross-chain communication relays, decentralized oracles, and multiple blockchain virtual machines simultaneously. A software fault, oracle mispricing, or exploit within any connected layer can impact pool solvency. The decentralized nature of the protocol means there are no government deposit protections, insurance schemes, or centralized chargeback mechanisms. Collateral positions carry continuous market risk, where sudden market downturns can trigger swift liquidations before a user can bridge additional funds or repay notable balances. Users must carefully manage position sizing and maintain conservative collateralization buffers to mitigate unexpected liquidation events.
