COCA Card vs Dune

The core offering of COCA combines a non-custodial smart wallet application with a physical and virtual debit card issued on major payment networks. Users can store, send, swap, and spend a wide variety of digital assets across major blockchain ecosystems, including Ethereum, Polygon, Arbitrum, Optimism, BNB Chain, and other EVM-compatible networks, alongside major stablecoins such as USDT and USDC.

Unlike traditional prepaid crypto cards that require selling tokens into a custodial fiat balance days in advance, COCA integrates directly with the user wallet balance. When a transaction is initiated at a point-of-sale terminal or online checkout, the underlying infrastructure facilitates asset conversion to fiat currency to settle the charge through conventional card payment channels.

In addition to card functionality, the COCA application provides an integrated decentralized exchange aggregator that routes token swaps across multiple liquidity pools. The platform also offers in-app fiat on-ramps and off-ramps managed by third-party payment processing partners, allowing users to buy digital currencies using conventional bank transfers or credit cards.

Dune operates primarily as a web-based data workspace that abstracts raw blockchain data into clean relational schemas. Supported networks span major Layer 1 and Layer 2 ecosystems, including Ethereum, Solana, Bitcoin, Arbitrum, Optimism, Polygon, and Base. Raw blockchain data, encompassing block headers, transaction receipts, and log traces, is parsed into structured tables via DuneSQL, an optimized query engine based on Trino. This structure allows researchers to query event logs, contract method calls, and transfer traces directly.

Beyond raw blocks, the platform provides curated datasets through its Spellbook repository, a community-maintained transformation layer powered by dbt. These abstractions aggregate complex protocol interactions, such as automated market maker swaps, lending pool liquidations, and non-fungible token marketplace sales, into standardised multi-chain tables. Visualisation modules allow users to turn raw table outputs into line charts, bar plots, area graphs, counters, and pie visualisations, which can be grouped into composite shareable dashboards. Protocol builders can publish project pages that display real-time ecosystem health metrics to the broader market, while analysts can fork existing community code to modify underlying parameters without starting from scratch.

Understanding the total cost of ownership on COCA requires looking at blockchain network fees, card issuance costs, foreign exchange markups, and liquidity conversion spreads. The application itself advertises zero commission on internal wallet transfers, but on-chain transactions remain subject to standard network gas fees determined by prevailing blockchain congestion.

For card spending, transactions settled in the local base currency of the card draw from selected crypto balances using prevailing market conversion rates. While basic domestic card transactions avoid fixed maintenance charges on standard tiers, cross-border payments or transactions outside the base fiat currency incur standard foreign exchange spreads and network conversion margins.

When acquiring cryptocurrency through the integrated fiat on-ramp or executing swaps, liquidity providers incorporate a dynamic spread into the quoted execution price. Users should review transaction confirmation screens carefully, as rapid market volatility can alter net conversion efficiency before final settlement completes on the ledger.

Dune uses a freemium model where users can sign up at zero initial cost to write public queries, build public dashboards, and explore community research. Free accounts receive a baseline allowance of monthly query execution credits, sufficient for casual exploration and standard research workloads. However, free accounts run on shared compute queues, which can lead to longer execution waiting times during peak network congestion, and all published work remains publicly visible.

For teams requiring dedicated resources, Dune provides paid commercial tiers, commonly structured around Plus and Premium subscriptions alongside custom Enterprise packages. Paid plans introduce private query authoring, private dashboards, larger allowances of monthly compute credits, prioritized query execution pipelines, and automated query scheduling. Furthermore, Dune offers programmatic API tiers priced according to monthly datapoint and execution unit allowances. Heavy data users consuming continuous streaming API responses or running resource-intensive historical aggregations must monitor their monthly credit burn rates closely, as additional compute units and private team seats scale total recurring costs.

Security across the COCA ecosystem is built on a non-custodial Multi-Party Computation framework. Traditional single private keys and standard twelve-word seed phrases are replaced by an MPC protocol that splits cryptographic key material into distinct mathematical shares. These mathematical shards are distributed between the user client device and independent server nodes. This structural separation prevents any single entity from authorizing transactions or accessing digital asset balances independently. Account access and recovery workflows operate through biometric verification, encrypted cloud storage backups, and multi-factor authorization checkpoints, eliminating the single point of failure inherent in paper backup phrases.

For routine card operations, standard cardholder management protections are integrated through licensed card issuing program managers. Account holders can immediately lock or unlock their virtual and physical debit cards within the mobile application interface. The platform allows users to configure granular spending thresholds, toggle contactless payment permissions, restrict magnetic stripe functionality, and control online card transaction capabilities directly. In addition, transaction monitoring and automated verification prompts help flag abnormal payment patterns across point-of-sale terminals before settlement occurs.

Dune is entirely non-custodial and read-only regarding asset management. The platform does not hold, transmit, custody, or manage cryptographic keys, wallet funds, or financial balances. Users connect to the analytics dashboard using standard email credentials or single sign-on mechanisms, with optional multi-factor authentication available to helps protect organizational accounts. Read-only wallet addresses can be queried publicly across raw ledger records, ensuring that no sensitive private keys are ever requested or stored on the platform servers.

From an organizational data security perspective, Dune supports role-based access management for corporate accounts and research teams. Workspace administrators can designate member permissions, control private dashboard visibility, and manage the generation and revocation of API keys. Network communications are secured through standard transport layer encryption protocols. Because public queries and schemas are accessible to all platform users by default, enterprise users managing proprietary trading strategies or unpublished commercial metrics must helps support their dashboards are explicitly set to private within paid team workspaces to prevent unintended strategy disclosure.

Access to the COCA Card is governed by regional issuing agreements and local financial regulations. Virtual and physical card issuance is primarily accessible to residents of eligible jurisdictions within the European Economic Area and the United Kingdom, subject to mandatory identity verification checks conducted by regulated issuing partners.

While the non-custodial wallet component can be downloaded and used globally without geographic restrictions, activating the debit card functionality requires full compliance with standard anti-money laundering and Know Your Customer regulations. Proof of identity and residential address documentation are mandatory before a card can be activated.

Customer support is delivered primarily through an in-app ticketing system, email assistance channels, and an online documentation knowledge base. Response turnaround times vary based on request complexity, particularly when inquiries involve transaction disputes that require coordination with external banking and card network partners.

Founded in Norway in 2018, Dune provides global web availability without traditional financial services licensing requirements, as it provides data analytics rather than investment execution or money transmission services. Access to the platform web portal and documentation is available internationally, subject to standard international sanction boundaries and acceptable use policies that prohibit malicious scraping or system abuse. Individual researchers and enterprise organisations can register accounts using standard email credentials or single sign on authentication without needing accredited investor verification.

Customer assistance is centered around an extensive public knowledge base, official platform documentation, and an active community Discord server. Free tier users primarily obtain assistance through community discussion channels and shared public forums, where experienced community analysts collaborate on SQL debugging and table mapping. Paid subscription tiers receive dedicated support routing, including direct technical assistance channels, higher service level agreements for enterprise accounts, and dedicated onboarding sessions for data engineering teams integrating Dune API streams into internal production data pipelines.
