They used Solidity for smart contracts and React for the frontend. For payments, the team used Ethereum and Stripe. **Review Rating**: 5.0 - Quality: 5.0 - Schedule: 5.0 - Cost: 5.0 - Willing to Refer: 5.0 **The Reviewer** Executive, NFT & Blockchain Startup - Industry: Other industries - Client size: 1-10 Employees - Review Type: Phone Interview - Verified **The Review** — Dec 5, 2022 **Feedback Summary**: The client was happy with Linum Labs’ work; the marketplace had 400–500 unique users transact through it. The team communicated effectively and tracked their agile process well through GitLab and GitHub. Moreover, they found budget solutions in the client’s favor and acted like a true partner. "“Linum Labs went the extra mile to act like a member of our team.”" **BACKGROUND** Introduce your business and what you do there. I’m an executive of an NFT and blockchain startup that helps nonprofits raise charity money through blockchain technology. **OPPORTUNITY / CHALLENGE** What challenge were you trying to address with Linum Labs? We hired them for blockchain and custom software development. **SOLUTION** What was the scope of their involvement? Linum Labs built an NFT marketplace for us. They designed and developed a fully custom marketplace, including smart contracts. In terms of technologies, they used Solidity for the smart contracts and React for the frontend. The process took six months. Part of this project's wireframing and discovery phase was devoted to researching on-ramp payment tools that could allow customers to pay with their credit cards in addition to cryptocurrencies. They used Ethereum as a cryptocurrency payment method and Stripe for payment processing. On the platform, our team uses an admin dashboard, and end users interact with the marketplace through our website.  What is the team composition? Throughout the project, we worked with 10 teammates from Linum Labs, including a project manager and a business developer, during the sales phase. The team also included a designer, a smart contract developer, and around two backend engineers.  How did you come to work with Linum Labs? We found them through a referral from former coworkers who made the connection, introducing us to Linum Labs.  How much have you invested with them? We spent around $70,000–$100,000.  What is the status of this engagement? We had our first contact around January 2021, the first engagement lasted from April–October 2021, and we had a second engagement from January–March 2022. **RESULTS & FEEDBACK** What evidence can you share that demonstrates the impact of the engagement?  Around 400–500 unique customers transacted through the marketplace.  How did Linum Labs perform from a project management standpoint? They were great communicators. We primarily used Discord for communication, though we also used Google Meet. The Linum Labs team transitioned from Discord to Slack on their side. For project management, we used GitLab to track the agile process, and later we used GitHub.  In a large fixed-cost project, estimating the scope in advance can be challenging. Trust and integrity are important in these cases, and Linum Labs demonstrated that they cared about our success. When they needed to step back and solve a problem, they found solutions in our favor cost-wise. As a result, I've spoken very highly of them and recommended them to others. Overall, they did a nice job of communicating and navigating the process.  What did you find most impressive about them? Linum Labs felt like a partner; they would check in frequently and overcommunicate during key periods. They put together a whole team effort to help us speak to one of our partners outside of billable time for them. Linum Labs went the extra mile to act like a member of our team, more than I had seen with previous providers.  Are there any areas they could improve? There was nothing they needed to improve.  Do you have any advice for potential customers? Provide Linum Labs with as much detail on the requirements as possible so that they understand what you're trying to accomplish and why. This detail is particularly important for designers.  The biggest challenge isn't just describing the project's scope but why you care about certain things because they'll have to make small decisions that represent what you want. Linum Labs did a really nice job of grasping what we wanted so that we didn't need to hold their hand through every micro-decision. --- #### OTC Tech Dev, UX/UI Design & Blockchain for OTC Tools Co **The Project** - Services: Blockchain, Custom Software Development, UX/UI Design - Project size: $50,000 to $199,999 - Project length: Aug. 2024 - Ongoing **Project Summary**: Linum Labs has developed decentralized OTC technologies for an OTC tools company.

They delivered the project on time and within the client’s budget, and the team communicated effectively with the client. Their workflow was seamless, and their teammates had great communication skills. Overall, the engagement was highly successful. "“Their communication was their biggest strength.”" **BACKGROUND** Introduce your business and what you do there.I’m the owner and co-founder of ApeVine, a wine authentication project on Web3 and with cryptocurrency technology.  **OPPORTUNITY / CHALLENGE** What challenge were you trying to address with Linum Labs?We hired Linum Labs to create a mobile app to read our wine labels with a chip on the back. Our ultimate goal was to solve a problem; we had a great way of authenticating wine, but we’d have to use a third-party app. We didn’t like any third-party apps since they were full of ads, free trials, pop-ups, and other things that we didn’t want to give to our customers. As a result, we decided to make an app with our branding.  **SOLUTION** What was the scope of their involvement?Linum Labs developed our custom mobile app. They also worked on its UI. I hadn’t developed an app before, so I was worried about dealing with a company that was either too expensive or didn’t understand what I was trying to do. Given that, the entire Linum Labs team sat down with me and talked me through everything to figure out what I needed. They started giving me a heads-up about what they were working on, which wasn’t what I wanted for the design. I gave them some notes, and they gave me exactly what I asked for after that. They built the app for iOS and Android. For features and functionality, the app could read an NFT chip that would take users to an authenticated version of our wines.How did you come to work with Linum Labs?Linum Labs was referred to us by another Web3 goer who discovered I was looking for an app builder. How much have you invested with them?We spent $4,000–$5,000. What is the status of this engagement?The engagement happened in October 2023. The product is finished, but it’s not live on the app stores yet. Nonetheless, our engagement with Linum Labs has been completed.  **RESULTS & FEEDBACK** What evidence can you share that demonstrates the impact of the engagement? Linum Labs met and exceeded our expectations.How did Linum Labs perform from a project management standpoint?They delivered work on time and on budget. For communication, they were in a different time zone, so I always woke up with a long list of items I had to talk to them about — they were as thoughtful as I was about launching on time. As a result, we worked together truly well. We used Slack to communicate.What did you find most impressive about them?Their communication was their biggest strength. Are there any areas they could improve?I wish they accepted credit cards.Do you have any advice for potential customers?Before engaging Linum Labs, ensure you have the cash because they don’t accept credit cards.  --- #### NFT Marketplace Design & Dev for NFT & Blockchain Startup **The Project** - Services: Blockchain, Custom Software Development, Other Design - Project size: $50,000 to $199,999 - Project length: Apr. 2021 - Mar. 2022 **Project Summary**: Linum Labs designed and developed an NFT marketplace for an NFT and blockchain startup.

Did they deliver items on time? How did they respond to your needs?Overall they were very proactive and responsive, and largely diligently held up their end of the bargain, certainly in terms of availability, efficiency and so on. Seemed to be a bit of internal and extrenal communication problems, as the handover of the project from one contract to another, and then from one project manager to another resulting in some diffivulties, incomprehensions, potential mistakes and so on (and hopefully not unnecesary time or monetary consumption).   Overall the service provided was certainly more than satisfactory and appreciated, but did not always perfectly align with certain (potentially not appropriate) expectation on our side. One major  point we were hoping for was more direct influence in the collaboration efforts from Linum's side, recognizing the obvious superior kowledge and experience from which we hoped to observe, understand and learn as much as possible.What was your primary form of communication with Linum Labs?Virtual MeetingEmail or Messaging AppWhat did you find most impressive or unique about this company?Their internationality and ability to allocate resources effectively stood out.Are there any areas for improvement or something Linum Labs could have done differently?nothing specific, as mentioned just sometimes communication seemed confusing or confused and there seem to have been some somewhat inefficient transfer from different contract, different proj managers etc, but overall absolutely more than satisfactory --- #### Blockchain Development for Development Company **The Project** - Services: Blockchain - Project size: $10,000 to $49,999 - Project length: Nov. 2022 - June 2023 **Project Summary**: A development company hired Linum Labs for blockchain development.

The platform allows creators to transform their existing content on indi.com into NFTs. Once creators upload their content and mint it as an NFT, they have the option to list it for Sale or Auction. In the Sale category, creators can mint additional copies of the NFT and set a price for interested users to purchase.Our responsibility encompassed the complete design process, full-stack development, and smart contract development to bring this vision to life. ### Fairdrive This project marks Linum Lab's early involvement in the Swarm Ecosystem as a development partner for one of its biggest projects built on top of the Swarm Blockchain Protocol, Fairdrive.The team was brought on board to develop both the middleware and UI front end for a file explorer that can communicate with the data on a lower system layer (for instance any database layer, including BEE Nodes on the Swarm Ecosystem). It would represent user data in an intuitive, designed Dapp made up of both a front end and a backend, namely the Fairdrive Dapp and Fairdrive Protocol. This first version for the project was considered a sandbox project, one that can inspire both the Fair Data Society and Swarm community and get people as excited to build as we were. ### MITO MITO is a cross, multidisciplinary, digital art gallery. Mito connects with artists and creators to publish limited and collectible artworks.  The first NFT curated art gallery dedicated to the entire community of Spanish-speaking artists.  MITO works together with artists to create unique collections that convey a story, a concept, a vision.   ### Ferry Ferry was created to be a Web 3 replacements for Web 2 tech. Centralized file transfer tools are wasteful by design, and the end users pay the costs.  We wanted to create a familiar workflow for file transfers - one that mirrors what people are already comfortable with to easily complete every days tasks like simply sending files. By uploading files on to IPFS, we get it’s content address, which we can use to create an IPFS gateway which can be used as is or emailed to the user’s recipient. After this, all we need to do is - Ferry it!   ### Polkalokr Polkalokr is a multi-chain token and locking and escrow platform designed to help both businesses and individuals manage their token economies.   By the use of two core products, LOKR and SWAPR, Polkalokr intends to build higher levels of trust in the Defi Space by targeting the weakest links in the crypto chain, The Human Element, and rather focusing on self-governance through code.   SWAPR is a protocol that allows peer-to-peer cross-chain token swapping, that features built-in privacy and multi-signature options. LOKR is a highly customisable token locking solution that acts as a traditional escrow.     ### Molecule Molecule is a marketplace for pharma and biotech IP such as compound patents or discoveries. Company’s research and development can now be moved from siloed pipelines into an open ecosystem. The model shifts the focus to be more directed towards suiting the needs of all stakeholders into early-stage compounds to make drug development more collaborative and faster. Molecule was born in-house and Linum Labs handled the entire process from conception to development and funding.  ### Swarm Bzzaar Built on the Ethereum blockchain, Swarm is a decentralised storage solution. This DApp aims to bring Web 2 storage to Web 3 via a protocol that encompasses openness, data liberation, and anti-censorship.  Our team at Linum Labs was tasked with designing a Bonding Curve for the sale of BZZ tokens, the protocol's utility token.We wanted a simple interface for the user to interact with the smart contract and make simple buy/sell orders for the token. ### Liquorice Gen Liquorice Gen is a liquidity solution for early-stage dapp’s that need to raise collateral to launch a token.   Liquorice Gen uses a bonding curve as an automatic market maker to accumulate enough collateral to transition to the Uniswap market.  Linum Labs handled the entire development of Liquorice Gen - building out it’s smart contract, bonding curve, and user interface for easy token creation.  ### UNXD UNXD is a curated marketplace for the best of digital culture.

A hash of the worker’s check-in / check-out activities is published to the blockchain so that the internal database can be audited to verify which worker was present and if they were correctly certified to work on that site. The app can also connect to identity systems authorized by city administrations, like Zug ID.  A self-sovereign blockchain-based identity is well-suited for this use case because workers should be able to carry over their identity from one company to another and no specific company should own or manage it. In addition, there are multiple companies and parties issuing certificates. ### Ether.fi A revolutionary liquid staking protocol bringing node operators and validators together. ### Bullion Pivot Bullion Pivot is an NFT marketplace that allows users to invest in real world assets such as Diamonds, Gold and Platinum.

Fans can picture their game- clinching touchdown drives, their buzzer-beating shots, and their iconic post-victory interviews. But we believe the life-defining moments, rather than the career-defining ones, are what truly matter. Not just the moments in the highlight reels, but the moments that got them there. Artists are masters of capturing these moments, their work evokes emotion, promotes thought, and ignites conversation. In pairing top athletes and all-star artists, we are amplifying stories that have been etched in our athletes' minds and inspiring viewers through the universal language of art. Etched is developing a platform that empowers users to purchase and invest in story-driven Non-Fungible Tokens (NFTs) placed on the platform by brands, influencers, and content creators. Etched needs an onramp into USDC via credit card, debit card, and ACH. Etched also needs a Digital Dollar Account solution, allowing users to buy and sell NFTs on Etched using USDC. Additionally, Etched needs an ACH and wires payout solution that will allow creators to get paid out in USD to their linked bank accounts. Etched is an anthology series that pairs artists with athletes to help illustrate a personal, relatable story that shaped the athletes' characters and careers these are highly focused anecdotes, visualized through video & animation, as well as an original piece of art. We aim to inspire audiences through highly visual and artistic pieces. The result will be 5-8 minute episodes, combining cinematic b-roll of the painting creation, mixed with interviews with both the athlete and artist, an animated reenactment of the story each athlete tells and a final reveal to see the athlete's authentic reaction to the one- of-a-kind, personalized artwork. ### DAOMeter DAOmeter is an industry-first rating system offering deep insights and transparency into the rapidly growing world of DAOs.
