2gether vs Euler Finance

2gether operated as a mobile first financial ecosystem combining centralized digital asset trading with an integrated payment card. The application delivered a consumer oriented interface tailored for casual retail participants who wanted straightforward entry into digital asset markets without managing private cryptographic keys. Supported assets centered on major market capitalization tokens, including Bitcoin, Ethereum, Ripple, Litecoin, Bitcoin Cash, and Basic Attention Token, alongside the proprietary 2GT utility asset.

The central feature of the ecosystem was the prepaid Visa debit card, which interfaced directly with the customer custodial cryptocurrency balances and fiat euro accounts. When cardholders initiated transactions at physical or online merchant terminals, the backend payment engine liquidated the selected digital asset into euros in real time to settle with the card network. This structure allowed seamless retail payments without requiring manual trades beforehand.

Beyond standard payment routing, the application included portfolio tracking tools, recurring buy setups, and community governance features tied to 2GT token ownership. Users could participate in informal voting rounds regarding upcoming asset listings or app improvements. While the asset catalog covered essential large cap tokens, it lacked deep secondary market coverage, specialized decentralized finance tokens, and granular order placement options like limit orders or margin facilities.

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.

2gether adopted a zero explicit trading commission marketing narrative, meaning spot conversions between euro balances and digital assets did not carry visible transaction line item fees. Instead, trading expenses were incorporated into execution spreads. The backend system sourced liquidity from multiple external partner exchanges, adding a markup between 1.0 percent and 2.5 percent depending on market volatility, selected token pair liquidity, and client 2GT holding tiers.

Token utility rules allowed users who accumulated substantial amounts of 2GT to access tighter spread bands and waived monthly card management fees. Standard users who did not hold minimum staking thresholds encountered standard spread margins on buys and sells. Physical card issuance was initially free or subject to nominal delivery costs, while standard point of sale transactions in euros did not attract domestic surcharge fees.

Withdrawal costs presented notable friction points throughout the platform lifecycle. Transferring cryptocurrencies out of the app to external non custodial wallets incurred standard blockchain network fees alongside internal processing surcharges. When the company initiated shutdown procedures in 2022, management imposed an unexpected twenty euro account maintenance fee on inactive retail balances, which provoked significant client friction during the final migration and asset withdrawal period toward partnered exchange facilities.

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.

2gether functioned as a purely custodial service provider, retaining full administrative control over cryptographic keys associated with user balances. Account holders did not hold private keys, passphrases, or individual seed backups. While this model simplified mobile onboarding for non technical consumers, it concentrated balance risks entirely within the corporate infrastructure and third party institutional wallet custodians.

Platform defenses relied on standard consumer authentication controls, including biometric authentication, mandatory two factor verification via SMS or authenticator apps, and algorithmic transaction monitoring for suspicious login locations. Cryptographic balances were primarily held in cold storage systems managed by institutional partners to mitigate online attack surfaces, with only small operational floats retained in warm wallets to settle daily card payments.

The limitations of this centralized custodial structure became evident during operational disruptions. In 2020, 2gether suffered a security compromise that resulted in the theft of approximately 1.2 million euros worth of digital assets from its operational hot reserves. Although the company sought to compensate affected users through 2GT token allocations rather than immediate liquid euro distributions, the event underscored the inherent risks associated with custodial multi asset mobile apps operating without comprehensive sovereign insurance coverage.

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.

2gether focused its operational presence across member states of the European Economic Area, specifically targeting consumers residing within Eurozone markets such as Spain, Portugal, Italy, and France. Due to cross border financial regulations and card scheme limitations, the platform did not accept registrations from residents of the United States, Canada, the United Kingdom, or high risk jurisdictions identified by international anti money laundering taskforces.

Onboarding required standard customer verification procedures in compliance with European Anti Money Laundering directives. Users submitted official identity documentation, such as national identification cards or passports, alongside live biometric facial verification and proof of residential address. Account approval was generally processed within several hours through automated verification tools, allowing newly approved users to generate virtual payment cards immediately while physical cards arrived by postal mail.

Customer support channels operated primarily through an in app ticket system, direct email assistance, and moderated social messaging channels. Response times and query resolutions were acceptable during normal operations but deteriorated significantly during market volatility spikes and security incidents. When service closure was announced in July 2022, support bandwidth was overwhelmed, leaving many users dependent on community forums and Bit2Me transition documentation to clarify balance retrieval instructions.

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.
