Argent vs ziglu

Argent operates as a non-custodial smart contract wallet provider, departing from traditional externally owned accounts that rely strictly on a private key pair. In this framework, every user account is an on-chain programmable contract. This foundational design allows Argent to incorporate native logic such as multisig approvals, batched transactions, trusted guardian recovery, and fine-grained session parameters without relying on third-party middleware or browser extensions.

Asset coverage centers on Ethereum tokens and Layer 2 ecosystems, most notably Starknet. Users can hold, transfer, and swap Ether (ETH), major stablecoins like USDC, USDT, and DAI, as well as native ERC-20 utility tokens and non-fungible tokens. Because Argent specializes in account abstraction on Starknet and Ethereum, it does not support non-EVM Layer 1 networks such as Bitcoin, Solana, XRP Ledger, or Cardano natively. Users interacting across decentralized finance applications on Starknet benefit from native Cairo smart contracts, which streamline signature verification and transaction bundling.

For portfolio tracking, Argent interfaces directly with integrated decentralized exchange aggregators and staking pools on-chain. While asset variety is narrower than generic multi-chain software wallets, the depth within supported ecosystems offers seamless connectivity to decentralized lending, automated market makers, and Starknet-native gaming applications.

Ziglu built its consumer offering around a unified multi asset mobile wallet designed primarily for United Kingdom retail customers. The application integrated a personal GBP electronic money account alongside custodial digital asset balances. This architecture allowed individuals to hold cash balances, receive bank transfers through dedicated account details, and execute instant spot conversions into selected cryptocurrencies without managing third party broker integrations or complex routing protocols.

The asset catalogue on the platform remained focused on high liquidity tokens rather than long tail altcoins. Supported assets historically included Bitcoin, Ether, Litecoin, Bitcoin Cash, Cardano, Tezos, and Solana. Users could also access stablecoin denominated products during specific operating phases. Rather than functioning as a high frequency trading desk, the product emphasized simplicity. Users selected a target token, reviewed a consolidated purchase quote, and confirmed transactions instantly. The closed loop structure meant that assets acquired within the ecosystem could not be transferred directly to external blockchain addresses, reinforcing its role as an entry level portfolio app rather than a gateway for decentralized finance activity.

Argent does not charge recurring subscription fees for downloading or holding assets in its software application. However, because each account is governed by on-chain smart contracts, initiating the wallet requires a one-time network deployment fee paid directly to network validators. On Ethereum Layer 1, deployment costs fluctuate heavily based on base gas prices, while deploying an account on Starknet costs substantially less due to zk-rollup computational compression.

When users perform asset swaps, staking deposits, or outbound withdrawals, transaction costs consist of network gas fees plus any third-party liquidity provider spreads. Argent incorporates third-party fiat on-ramp providers like MoonPay and Ramp Network for purchasing crypto with debit cards, bank transfers, or Apple Pay. These payment routes apply processing surcharges ranging from 1.5% to 4.5% depending on payment method and geographic jurisdiction, alongside liquidity partner spreads.

Integrated in-app token swaps leverage decentralized liquidity aggregators. While Argent may include a nominal routing fee on specific swap routes to fund client development, transactions remain fully non-custodial. Network fees for adding or revoking guardians require smart contract execution calls, which users must fund using their on-chain account balance during standard network conditions.

The cost structure across the platform centered on an explicit transaction fee combined with underlying market liquidity spreads. For standard spot crypto purchases and sales, the service applied a baseline commission of 1.25 percent per transaction. This transparent flat rate eliminated tiered volume calculations for casual users, though it represented a higher cost baseline than high volume international spot exchanges. Foreign currency exchange transactions executed on the debit card operated with competitive exchange markups during standard operating hours.

Fiat deposits and withdrawals using the UK Faster Payments network carried no platform surcharges, enabling efficient movement of sterling between traditional bank accounts and the application. The Ziglu debit card did not levy monthly maintenance fees or domestic point of sale charges. However, ATM cash withdrawals were subject to network limits and potential operator surcharges after exceeding complimentary monthly allowances. Because the platform did not support on-chain crypto deposits or withdrawals, users avoided direct blockchain network gas fees, but they remained bound to liquidating their holdings into cash before transferring value outside the ecosystem.

Security in Argent is anchored by smart contract logic rather than standard custodial infrastructure. Users retain exclusive authority over their on-chain funds. Traditional seed phrases are replaced by a distributed social recovery mechanism called Guardians. A guardian can be a hardware wallet, a secondary mobile device, a trusted contact, or an automated Argent security service using biometric email verification. Guardians have the authority to approve account recovery and large transfers exceeding defined thresholds, but they cannot access or steal user balances independently.

The application implements customizable daily spending limits. Transactions falling below the chosen threshold execute seamlessly with device biometrics such as Face ID or fingerprint authentication. If a transaction exceeds the daily threshold, guardian confirmation is required before the smart contract releases funds, creating an on-chain time buffer against unauthorized transfers. Additionally, untrusted address interactions can be subjected to a 24-hour settlement cooldown period to allow users time to cancel fraudulent requests.

Smart contract codebases for Argent and its Starknet modules are open source and subject to public audits by independent security research firms. While smart contract execution removes single-point seed phrase compromise, users must acknowledge underlying smart contract technical risks, protocol upgrade governance, and network validator consensus rules.

Account security and asset safekeeping on the platform followed a centralized custodial framework. Fiat balances held within the electronic money account were maintained under helps protect requirements with authorized UK credit institutions, separating customer funds from operational corporate accounts. It is important to note that electronic money balances and crypto assets held within the platform do not benefit from Financial Services Compensation Scheme statutory deposit protection.

Digital assets were managed through third party institutional custody partners utilizing segregated cold storage facilities and multi signature transaction signing mechanisms. The application incorporated standard consumer protective controls, including biometric login authentication, two factor SMS verification codes, device pairing restrictions, and instant card freezing toggles within the mobile settings. While these helps protect helped protect against unauthorized remote access, users did not hold individual private keys. Custody risks remained tied to the operational continuity and solvency of the corporate entity and its custody partners, underscoring the structural distinction between centralized consumer fintechs and self sovereign wallet solutions.

Argent is distributed internationally as a mobile application for iOS and Android devices, alongside a dedicated browser extension built specifically for Starknet ecosystem dApps. Because Argent is a self-custody software interface, users worldwide can download the client and interact with public blockchains without undergoing mandatory identity verification or know-your-customer checks for basic on-chain functionality.

Regulatory and identity verification requirements apply selectively when interacting with third-party payment rails. If a user chooses to purchase crypto using integrated fiat on-ramps or off-ramps, those external financial institutions mandate identity verification under local anti-money laundering regulations. Certain geographic regions subject to international financial sanctions face restricted access from integrated third-party on-ramp partners, though the core open-source wallet interface remains accessible for permissionless peer-to-peer transfers.

Customer support for Argent is structured around self-service documentation, community discussion channels, and direct ticketing via in-app help desks. Because Argent operates without custody of private keys or funds, technical support agents cannot reverse confirmed on-chain transactions, modify guardian sets, or bypass smart contract spending rules. Onboarding documentation provides step-by-step guidance for setting up guardians, managing Starknet accounts, and troubleshooting failed network interactions.

Eligibility for opening an account was strictly limited to legal residents of the United Kingdom aged 18 and older. Prospective users were required to complete mandatory identity verification procedures, including submitting government issued photo identification, completing automated facial biometric scans, and verifying domestic residential address details. The service was structured around domestic UK banking rails and did not open registrations to international users or institutional entities.

Ziglu operated as an Electronic Money Institution registered representative and achieved registration with the Financial Conduct Authority as a cryptoasset firm under anti money laundering regulations. Customer support was provided primarily through an in-app messaging desk and standard email channels during regular business hours. Response times varied based on operational inquiry volumes. When the firm faced solvency challenges and subsequently entered special administration, standard customer service channels transitioned to administrative updates overseen by court appointed insolvency practitioners, highlighting the essential role regulatory oversight plays during corporate transitions.

Adopting a smart contract wallet introduces distinct operational boundaries compared to standard hardware or paper backup wallets. Because the account lives on-chain, loss of access to all configured guardians and authentication channels can permanently isolate assets. Maintaining active, redundant guardians is necessary to helps support long-term recovery viability.

Furthermore, smart contract upgrades and protocol migrations require user awareness. When interacting with experimental decentralized applications on Layer 2 networks, smart contract vulnerabilities in third-party protocols remain outside Argent's protective scope. Users must independently verify smart contract addresses and contract approval permissions prior to authorizing transactions.

Users navigating the platform had to operate within defined compliance and activity thresholds established for retail accounts. The application maintained daily and annual transaction caps on debit card purchases, automated teller machine withdrawals, and domestic account transfers to satisfy regulatory anti money laundering monitoring standards. Attempting to route funds from unverified third party accounts or engaging in high frequency commercial activities frequently triggered automated account reviews or temporary payout holds. Understanding these operational risk boundaries was essential for account holders, as all incoming and outgoing actions were strictly monitored by compliance filters designed exclusively for personal retail use rather than business payment processing. Exceeding set velocity limits required manual documentation checks before account features could be restored.

The total cost of using Argent depends on the network selected and the frequency of security updates. Deploying an account on Ethereum Layer 1 can range from 15 USD to over 50 USD during periods of elevated base gas prices. In contrast, deploying on Starknet typically costs less than 1 USD in native network gas fees.

Configuring a secondary hardware wallet as a guardian requires paying standard network interaction fees to update the smart contract state. Routine transfers and token swaps on Layer 2 remain economical, with individual transaction fees generally costing pennies, making regular DeFi interaction practical compared to mainnet execution.

Evaluating standard user journeys highlights how the fee model impacted everyday balances. A retail user buying 500 GBP worth of Bitcoin paid a 1.25 percent commission of 6.25 GBP, alongside any minor embedded spread at execution. Selling that position later incurred an equivalent 1.25 percent charge on the realized value. For routine domestic debit card spending, a customer spending 50 GBP at a local grocery store incurred zero card transaction fees. When traveling abroad, point of sale transactions utilized Mastercard interbank rates without supplemental platform load fees, presenting a viable alternative for modest international holiday spending compared to standard high street bank cards.
