BEST COMPANIES · DEFI **There is no single best DeFi development company for every project: the right one has delivered protocols similar to yours, has the code independently audited before it moves money and leaves the keys that can change it in your hands.** This guide sums up the risks of a DeFi protocol, what MiCA says about decentralized finance and what to ask the provider. **How we chose the providers.** Besides Unknown Gravity, which publishes this page and appears first without being assessed against the criteria, a company is listed only if it meets three conditions, each backed by a source we opened on October 14, 2026: (1) according to its own website, custom blockchain development for clients is its core business; (2) the company is on an official business register; (3) its website describes a DeFi project with the client named. We do not use figures reported by the companies, such as the value deposited in their protocols. The numbering is not a quality ranking. The right DeFi development company has delivered protocols similar to yours, has the code independently audited before it moves money and leaves the keys that can change it in your hands. A provider is listed only if custom blockchain development for clients is its core business, it is on an official business register and its website describes a DeFi project with the client named. Checked on October 14, 2026: Unknown Gravity, which publishes this page, LimeChain and Nextrope. | Company | What it does | Registration checked | Based in | | --- | --- | --- | --- | | Unknown Gravity | DeFi protocols on Ethereum and EVM networks | [Commercial Register of Málaga, sheet MA-177027](https://www.boe.es/borme/dias/2023/10/18/pdfs/BORME-A-2023-199-29.pdf) | Málaga (Spain) | | LimeChain | Governance contracts for DeFi protocols, with Tally | [Bulgarian Commercial Register, EIK 204318511](https://portal.registryagency.bg/CR/en/Reports/ActiveConditionTabResult?uic=204318511) | Sofia (Bulgaria) | | Nextrope | DeFi lending on Arbitrum, Polygon and the XRP Ledger | [Polish KRS, No. 0000727128](https://api-krs.ms.gov.pl/api/krs/OdpisAktualny/0000727128?rejestr=P&format=json) | Gdynia (Poland) | ## Unknown Gravity: DeFi protocols on Ethereum and EVM networks Unknown Gravity is a technology company based in Málaga, Spain, and the publisher of this page. According to its website, it builds and audits [DeFi protocols](/en/servicios/protocolos-defi) and works on Ethereum and EVM networks such as Arbitrum, Polygon and Base. Its [smart contract audits](/en/servicios/blockchain-security-audits) are scoped to a specific version of the code. - **Where it operates:** from Málaga, Spain. - **Registration:** Unknown Gravity, S.L., Commercial Register of Málaga, sheet MA-177027; its incorporation was published in the [BORME of October 18, 2023](https://www.boe.es/borme/dias/2023/10/18/pdfs/BORME-A-2023-199-29.pdf). It is a technology provider, not a regulated intermediary. **Where it fits:** you want to own the contracts and need both the development and a security review. **Where it does not:** you are looking for someone who will also operate the protocol or provide crypto-asset services; providing those services requires authorization (Article 59(1) of MiCA). ## LimeChain: governance contracts for DeFi protocols, with Tally LimeChain presents itself as a blockchain consulting and development company. According to its website, it writes smart contracts in Solidity, Rust and Daml, does protocol engineering and builds full products, including DeFi. - **Where it operates:** from Sofia, Bulgaria. - **Registration checked:** Lime Labs EOOD, on the [Bulgarian Commercial Register](https://portal.registryagency.bg/CR/en/Reports/ActiveConditionTabResult?uic=204318511) under EIK number 204318511, with its registered office in Sofia. - **DeFi project:** according to the [Tally case study](https://limechain.tech/clients/tally) on its website, Tally offers governance tools for DeFi protocols; LimeChain tested and audited the subgraphs on The Graph that Tally uses to index on-chain data and built the smart contracts that refund the gas spent on votes, to make taking part cheaper. The case study includes a quote from Tally founder Dennison Bertram. **Where it fits:** your protocol needs on-chain governance, data indexing or low-level engineering. ## Nextrope: DeFi lending on Arbitrum, Polygon and the XRP Ledger Nextrope describes itself as a digital asset infrastructure studio for EVM networks and the XRP Ledger. The services listed on its website include DeFi protocol engineering, EVM smart contracts, XRPL engineering and production support. - **Where it operates:** from Gdynia, Poland. - **Registration checked:** Next Enterprises sp. z o.o., a limited liability company registered on April 11, 2018 in [Poland's National Court Register (KRS)](https://api-krs.ms.gov.pl/api/krs/OdpisAktualny/0000727128?rejestr=P&format=json) under number 0000727128, with its registered office in Gdynia. - **DeFi projects:** the [Soil case study](https://nextrope.com/soil-case-study), a DeFi lending marketplace that connects crypto lenders with real-world companies, for which it implemented the smart contracts on Arbitrum and Polygon, the backend and the data indexing; and the [Straid Protocol case study](https://nextrope.com/straid-case-study), a native credit layer on the XRP Ledger with borrowing and automatic liquidations on-chain, without custodians. **Where it fits:** your DeFi product relies on real-world assets or companies, or you will build on the XRP Ledger. ## The risks of a DeFi protocol The European Securities and Markets Authority (ESMA) looked at decentralized finance in a [report dated October 11, 2023](https://www.esma.europa.eu/sites/default/files/2023-10/ESMA50-2085271018-3349_TRV_Article_Decentralised_Finance_in_the_EU_Developments_and_Risks.pdf). It is a risk analysis, not a rule. It concludes that, although investors' exposure to DeFi was small, there are serious investor protection risks for three reasons: the highly speculative nature of many DeFi arrangements, significant operational and security vulnerabilities, and the lack of a clearly identified responsible party. For a developer, those risks look like this: - **Code errors.** If a contract has a flaw, the loss is usually irreversible. ESMA notes that many protocols go live without an audit and that, because the code is public, its vulnerabilities are exposed to attackers. - **Admin keys and governance.** Whoever can upgrade or pause a contract can also change its rules. ESMA cites 2022 exploits that targeted the consensus or governance mechanisms of some protocols. - **Oracles.** A manipulated price in the external data feed can trigger liquidations or loans that should not happen. - **Dependencies.** Stablecoins, oracles and bridges between networks are, according to ESMA, core components of DeFi: if one fails, the protocol that depends on it fails too. - **Market manipulation.** ESMA mentions techniques specific to DeFi, such as maximal extractable value (MEV) and flash loan attacks. The same report warns that putting some decisions to a DAO vote does not make a protocol fully decentralized. How these pieces work, in [what decentralized finance is and how it works](/en/articulos/defi-que-son-como-funcionan-finanzas-descentralizadas). ## Audits: what to ask for and what they do not guarantee An audit reduces risk, but it does not remove it. To be useful, it must meet these conditions: - **Independent:** it is done by a team that did not write the code. - **On the exact version** that will be deployed, identified by its commit, and repeated after every significant change. - **With a full report:** findings, severity, fixes and a new review of what was fixed. If possible, publish it. - **Backed by tests:** automated tests of the properties that must never break (for example, that what is borrowed never exceeds what the collateral allows) and attack scenarios. - **With controls after deployment:** a multisig and a waiting period (timelock) for changes, a limited and documented pause, monitoring and an incident response plan. More detail in [how a smart contract audit works](/en/servicios/blockchain-security-audits). ## MiCA and DeFi: what recital 22 says The [MiCA Regulation](/en/glosario/mica-reglamento-criptoactivos) (Regulation (EU) 2023/1114) applies to anyone who issues, offers to the public or seeks admission to trading of crypto-assets, or provides services related to crypto-assets in the EU (Article 2(1)). On decentralized finance, what matters is in a recital, not in an article: - **Recital 22.** MiCA also applies when part of the activities or services is performed in a decentralized manner. Only crypto-asset services provided in a fully decentralized manner, without any intermediary, should fall outside its scope. And if a crypto-asset has no identifiable issuer, Titles II, III and IV do not apply to it, but providers offering services in respect of it are still covered by the Regulation. - **No definition in the articles.** MiCA's articles do not define what "fully decentralized" means. Decentralized finance only appears in the articles that require reports from the European Commission: the one in Article 142(2)(a), which was to assess whether regulating it is necessary and feasible, and the report on the application of the Regulation, due by June 30, 2027 (Article 140(2)(t)). - **If there is an intermediary,** providing crypto-asset services in the EU requires being an authorized crypto-asset service provider or one of the entities in Article 60 (Article 59(1)). - **If the token is a financial instrument,** MiCA does not apply (Article 2(4)(a)) and securities law governs instead. For the legal analysis, practical questions carry weight: who can upgrade or pause the contracts, who runs the website through which the protocol is used, who collects fees and who decides on changes. For a first look at how your token may be classified, try the [MiCA/MiFID classifier](/en/clasificador-mica-mifid); the decision belongs with your legal counsel. ## What to ask a DeFi development company 1. **Similar protocols in production**, with the contracts verified on the network's block explorer and the client named. 2. **An independent audit** built into the plan, with its schedule and time set aside for fixes. 3. **Control of the keys:** deployment and admin keys in a multisig you control; the provider should not be able to change the protocol on its own. 4. **Ownership of the code** and a list of third-party components with their licenses. 5. **A documented economic design:** collateral, liquidation and fee parameters, and what happens in extreme market scenarios. 6. **Operation after launch:** monitoring, an incident plan and who responds outside business hours.

There is no single answer. The companies in this guide build custom blockchain software, are on a business register and have published DeFi work with the client named. The right one depends on the network, the type of protocol (lending, exchange, governance) and who will operate it. ### Is a DeFi protocol subject to MiCA? It depends on how it is provided. Under recital 22 of MiCA, only services provided in a fully decentralized manner, without intermediaries, fall outside its scope, and the Regulation does not define that concept in its articles. If an entity provides crypto-asset services, it needs authorization (Article 59(1)). Review it with your legal counsel before launch. ### Is an audit enough to launch? No. An audit reviews a specific version of the code; after that you need controls over the keys, monitoring and an incident plan. ESMA notes that many protocols go live without an audit and that, because their code is public, their flaws are exposed. ### Why does Unknown Gravity appear first? Because it publishes this page.
