Our take

Euler Finance

Euler Finance represents an advanced iteration in decentralized credit markets through its modular Euler Vault Kit and Ethereum Vault Connector architecture. Instead of pooling broad asset classes into a monolithic liquidity layer, Euler enables developers and liquidity allocators to build isolated, customized lending vaults tailored to distinct collateral profiles. This flexible model allows depositors to target yield from mainstream tokens or specialized niches while containing exposure to specific vault silos.

For sophisticated DeFi market participants, Euler delivers powerful primitives for borrowing, passive yield generation, and cross-vault collateralization. However, this flexibility requires users to exercise strict diligence regarding oracle sources, liquidation thresholds, and vault curators. Euler serves as a technically sophisticated, non-custodial lending framework suited for users comfortable navigating on-chain risk parameters and autonomous contract mechanics.

haru invest

Haru Invest stands as an essential case study in counterparty exposure within centralized crypto yield products. Founded as a subsidiary under Block Crafters, the service attracted global deposits by marketing automated, market-neutral trading strategies on assets such as Bitcoin, Ether, and stablecoins with double-digit annual returns. However, the architecture relied heavily on opaque third-party fund managers rather than internal, verifiable hedging. When key external partners collapsed in June 2023, the platform froze all customer balances abruptly. In November 2024, South Korean courts declared Haru Management Limited formally bankrupt. We view the platform strictly through the lens of distressed creditor resolution rather than an active financial service. Depositors face protracted court proceedings, underscoring the fundamental risks inherent in uncollateralized yield models.

Modular lending architecture and asset breadth

Euler Finance

Euler operates as a permissionless, non-custodial credit network built around the Ethereum Vault Connector standard. At its core, the protocol decouples lending pools into discrete vaults using the Euler Vault Kit. This allows market creators to configure independent risk configurations, custom interest rate models, and designated oracle integrations. Rather than forcing all assets to share a single systemic risk pool, Euler accommodates diverse token tiers ranging from established crypto assets like ETH, WBTC, and major stablecoins to long-tail yield tokens and liquid staking derivatives.

Borrowers can deposit accepted collateral to draw loans against liquidity supplied by passive yield seekers. Because vaults can be paired or isolated, governance or vault creators can establish permissionless credit markets without introducing contagion risk to separate pools. The modular design also facilitates yield aggregation strategies through managed vault routers, allowing depositors to automatically distribute liquidity across vetted lending markets while retaining granular visibility over individual vault mechanics.

Historically, Haru Invest structured its catalog around three primary investment tiers designed to capture market volatility and arbitrage opportunities. The entry program, Haru Wallet, operated as a flexible savings balance that generated low baseline returns without mandatory lockup intervals. Users looking for enhanced yields committed capital to Haru Earn Plus, which required fixed lock periods ranging from fifteen to three hundred sixty-five days in exchange for higher target rates. The most speculative tier, Haru Earn Explore, functioned as an algorithmic strategy product linked to specific market indices, exposing principal to potential drawdown depending on market movements.

Supported assets were deliberately concentrated on foundational digital tokens rather than broad altcoin listings. The platform accepted deposits in Bitcoin, Ethereum, Tether, USD Coin, and XRP. Capital deployment was presented to depositors as high-frequency trading, statistical arbitrage, and yield spread capture across diverse global exchanges. In practice, substantial portions of pooled user funds were outsourced to external trading firms, most notably B and S Holdings, without direct user transparency. This structural delegation removed direct custody oversight from internal operators, creating severe vulnerability to external default. Today, the catalog is entirely inoperative, serving only as historical evidence in ongoing bankruptcy distributions.

Interest rate models and protocol fee structure

Euler Finance

Euler utilizes algorithmic, utilization-based interest rate models to balance lending supply and borrowing demand across individual vaults. Borrowers pay variable borrowing rates that adjust dynamically as pool utilization changes, with higher utilization driving elevated borrowing costs to incentivize additional supply or debt repayment. Lenders earn the interest paid by borrowers proportional to their share of the vault, minus any protocol-level or vault-governor reserve fees configured within that specific pool.

The protocol does not charge custodial deposit or withdrawal surcharges, though users must pay underlying network gas fees for every on-chain interaction. In addition, when loans become undercollateralized, third-party liquidators trigger automated liquidation processes subject to predefined liquidation discounts. Protocol revenue and reserve fees, where active, flow back into vault reserves or decentralized governance mechanisms rather than intermediary corporate treasuries. Because liquidity depth varies across individual vaults, users must assess utilization levels to gauge potential withdrawal friction during high-demand intervals.

During regular operations, Haru Invest did not levy direct management or subscription fees on basic flexible wallet balances. Instead, the firm extracted revenue from performance splits on yield-bearing accounts. On specific Earn Explore strategies, the platform charged an operational fee of fifteen percent calculated strictly on gross profits generated, waiving fees when performance targets fell flat. Regular withdrawals incurred fixed network transaction charges standard across the digital asset sector, with specific rates adjusted dynamically according to underlying blockchain congestion and gas costs for Bitcoin and Ethereum.

Liquidity mechanisms completely disintegrated on June 13, 2023, when Haru Invest announced the sudden cessation of all deposit and withdrawal operations. The company cited fraudulent reporting from partner asset manager B and S Holdings, which reportedly caused massive losses exceeding hundreds of millions of dollars. As a result, depositors lost all ability to redeem locked or flexible balances. The subsequent declaration of corporate bankruptcy by the Eleventh Bankruptcy Division of the Seoul Bankruptcy Court on November 20, 2024, permanently transitioned user balances into distressed creditor claims. No public liquidity, secondary transfer market, or standard withdrawal pathway remains accessible for any account holder.

Smart contract security, isolation, and user custody

Euler Finance

Euler operates on a strictly non-custodial model where user funds remain governed entirely by smart contracts. Users retain exclusive authority over their wallet signatures and private keys, interacting with Euler contracts directly through Web3 interfaces or programmatic transaction routing. The protocol does not maintain custodial accounts, user verification databases, or administrative recovery backdoors for lost credentials.

Following an exploit in its v1 implementation in 2023, Euler rebuilt its infrastructure with the modular v2 architecture, focusing extensively on formal verification, multi-firm code audits, and isolated risk containers. The Ethereum Vault Connector functions as an agnostic base layer, ensuring that vulnerabilities in an individual isolated vault cannot automatically compromise liquidity in independent vaults. Users can further manage operational safety by interacting through hardware wallets, multi-signature setups, and reviewing the specific price oracle feeds and governor parameters applied to each market.

Haru Invest operated a strictly custodial service where deposited private keys remained under centralized enterprise management rather than user control. Account-level security features included mandatory multi-factor authentication, biometric logins on mobile applications, and automated session timeouts. While internal technical infrastructure utilized enterprise-grade multi-party computation tools, these technological helps protect failed to mitigate structural financial counterparty risk. Depositors were required to relinquish complete operational ownership of their tokens upon transfer to platform collection addresses.

The critical point of failure stemmed from corporate governance and external treasury delegation rather than cryptographic network breaches. Despite assurances of internal risk management protocols, management concentrated user assets within external speculative accounts lacking segregated custodial trust accounts or deposit insurance protections. Following the withdrawal freeze, investigative authorities initiated legal actions against key executives, leading to arrests on fraud and embezzlement allegations. The absence of on-chain proof of reserves or independent third-party asset audits left depositors without visibility into balance sheet solvency until total failure occurred. Security architecture cannot protect capital when internal counterparty governance fails completely.

Global accessibility, governance, and technical support

Euler Finance

Euler is deployed as an open-source, permissionless blockchain protocol accessible across supported EVM networks globally. The core smart contracts operate autonomously without centralized onboarding barriers, territorial identity checks, or credit-scoring intermediaries. However, front-end web interfaces maintained by community contributors or foundation entities may apply standard geo-blocking measures to align with specific regional regulatory constraints. Users interacting directly with deployed smart contract addresses retain native access regardless of geographic jurisdiction or front-end hosting policies.

Governance of the protocol ecosystem is facilitated through the Euler DAO and holders of the EUL governance token, who vote on protocol upgrades, fee allocations, and core architectural implementations. Because Euler is decentralized, conventional customer help desks and live agent support do not exist. Technical assistance, educational documentation, and protocol updates are handled through developer guides, technical forums, and community channels where participants discuss vault configurations and ecosystem developments. Users should independently review open-source documentation and community discussion threads to troubleshoot transaction questions.

haru invest

Prior to its operational collapse, Haru Invest served an international clientele across more than one hundred forty jurisdictions, relying on an offshore corporate registration under Haru Management Limited in the British Virgin Islands, alongside operations out of South Korea. The service actively restricted users in sanctioned territories and regions requiring localized money transmitter licenses. However, the platform operated without formal financial regulatory oversight, full banking authorization, or statutory investor compensation scheme protections in the major territories where it solicited user funds.

Standard customer support channels, which formerly offered ticket-based email assistance and community chat moderation, have ceased all routine account servicing. Communication is now restricted to official bankruptcy notifications, legal filings, and designated creditor reporting protocols managed by court-appointed bankruptcy trustees in Seoul. Claimants must submit documentation validating historical account ownership, deposit transaction IDs, and verified balance statements directly through approved judicial bankruptcy channels. Regular account assistance, feature updates, and routine dispute resolutions are entirely unavailable as the entity undergoes court-ordered asset discovery, valuation, and liquidation.

Who it suits

Euler Finance

Euler Finance is well suited for self-directed DeFi yield seekers, algorithmic market makers, and liquidity managers who require customizable, isolated credit vaults. Users should be experienced in managing self-custody wallets, reading smart contract risk disclosures, and evaluating decentralized oracle mechanisms before allocating capital. Sophisticated liquidity providers who appreciate granular control over collateral ratios and interest rate curves can leverage isolated risk boundaries effectively. The platform also appeals to technical teams looking to deploy bespoke credit markets without liquidity contagion across unrelated pools. Participants must be comfortable taking full personal ownership of risk assessments without relying on centralized customer service support.

haru invest

Haru Invest is no longer functional for active cryptocurrency investors or yield seekers. The platform is relevant exclusively to existing account holders seeking information on formal creditor claims, court-ordered asset valuations, and potential liquidation dividends through the Seoul Bankruptcy Court. It also serves as an educational risk benchmark for institutional researchers, compliance professionals, and retail market participants studying the failure modes of centralized yield models. Those looking to deploy digital assets today must bypass defunct centralized platforms and explore self-custody arrangements, transparent decentralized finance protocols, or fully regulated exchange venues that maintain audited, segregated client funds.
