How to choose the best blockchain software house?

In April this year, Clutch and The manifest sites ranked Nextrope as one of the top blockchain companies in the world. Thanks to our customers' feedback we have also become the first ICO consultant in Europe (and second in the world). Why according to them Nextrope is probably the best Polish blockchain software house?

Clutch and The Manifest are some of the most important platforms that collect company reviews from business customers. For millions of entrepreneurs they provide essential support in the search for IT contractors. Based on the reviews, the services complete rankings of the best companies offering services in a given technology area.

Second place in the blockchain category at The Manifest

In April, we were ranked #2 among the top 100 blockchain software houses on The Manifest website. We owe it to 100% positive feedback from our customers, including this Alior Bank, for which we integrated API, offering methods of signing and publishing transactions on blockchain.

Based on the reviews of its users, Clutch ranked us 6th among all companies present on the site. On the other hand, in Leader Matrix we were rated as the 10th best blockchain software house.

As far as the ranking of European companies is concerned, only two companies ranked ahead of us. 

8th place in Ethereum category on Clutch 

In the Clutch ranking based on customer feedback, Nextrope ranks 8th in Europe and 13th in the world among the top blockchain software houses working with the Ethereum protocol. 


How Nextrope came to be among the top blockchain software houses?

For 3 years we have been trying to set trends for the fintech industry in Poland. Already in 2019, we organized the largest conference in Central Europe entirely dedicated to Blockchain technology. We are also responsible for conducting one of the first 30 tokenizations in the world. 

We approach each project individually, making every effort to ensure that our skills and experience translate into the success of our clients. Among them are both revolutionary startups such as LexSecure, Gameset and the seventh largest bank in Poland - Alior bank. It is on the basis of their opinions that Clutch and The Manifest placed us so high in their rankings.

Blockchain for Creators: Secure and Sustainable Infrastructure

Blockchain for Creators: Secure and Sustainable Infrastructure

In today’s digital creative space, where the lines between art and technology are constantly blurring, projects like MARMALADE mark the beginning of a new era - one where creators can protect their work and maintain ownership through blockchain technology.

For Nextrope, being part of MARMALADE goes far beyond implementing features like screenshot blocking or digital watermarking. It’s about building trust infrastructure - systems that empower creators to thrive in the digital world safely and sustainably.

A new kind of blockchain challenge

Cultural and educational projects come with a completely different set of challenges than typical DeFi systems. Here, the focus isn’t on returns or complex smart contracts - it’s on people: artists, illustrators, educators.

That’s why our biggest task was to design secure yet intuitive infrastructure - lightweight, energy-efficient, and accessible for non-technical users exploring Web3 for the first time.

“Our mission wasn’t to build another financial protocol. It was to create a layer of trust for digital creators.”
— Nextrope Team

Security that stays invisible

The best security is the kind you don’t notice.
Within MARMALADE, we focused on making creators' protection seamless:

  • Screenshot blocking safeguards artworks viewed in browsers.
  • Dynamic watermarking helps identify unauthorized copies.
  • Blockchain registry ensures every proof of ownership remains transparent and immutable

“Creators shouldn’t have to think about encryption or private keys - our job is to make security invisible.”

Sustainability by design

MARMALADE also answers a bigger question - how to innovate responsibly.
Nextrope’s infrastructure relies on low-emission blockchain networks and modular architecture that can easily be adapted for other creative or cultural initiatives.

This means the technology built here can support not only artists but also institutions, universities, and educators seeking to integrate blockchain in meaningful ways.

Beyond technology

For Nextrope, MARMALADE is more than a project — it’s proof that blockchain can empower culture and creators, not just finance. By building tools for digital artists, we’re helping them protect their creativity and discover how technology can amplify human expression.

Plasma blockchain. Architecture, Key Features & Why It Matters

Plasma blockchain. Architecture, Key Features & Why It Matters

What is Plasma?

Plasma is a Layer-1 blockchain built specifically for stablecoin infrastructure combining Bitcoin-level security with EVM compatibility and ultra-low fees for stablecoin transfers.

Why Plasma Blockchain Was Created?

Existing blockchains (Ethereum, L2s, etc.) weren’t originally designed around stablecoin payments at scale. As stablecoins grow, issues like congestion, gas cost, latency, and interoperability become constraints. Plasma addresses these by being purpose-built for stablecoin transfers, offering features not found elsewhere.

  • Zero-fee transfers (especially for USDT)
  • Custom gas tokens (separate from XPL, to reduce friction)
  • Trust-minimized Bitcoin bridge (to allow BTC collateral use)
  • Full EVM compatibility smart contracts can work with minimal modifications

Plasma’s Architecture & Core Mechanisms

EVM Compatibility + Smart Contracts

Developers familiar with Ethereum tooling (Solidity, Hardhat, etc.) can deploy contracts on Plasma with limited changes making it easy to port existing dApps or DeFi, similar to other EVM-compatible infrastructures discussed in the article „The Ultimate Web3 Backend Guide: Supercharge dApps with APIs".

Gas Model & Token Mechanism

Instead of forcing users always to hold XPL for gas, Plasma supports custom gas tokens. For stablecoin-native flows (e.g. USDT transfers), there is often zero fee usage, lowering UX friction.

Bitcoin Bridge & Collateral

Plasma supports a Bitcoin bridge that lets BTC become collateral inside smart contracts (like pBTC). This bridges the security of Bitcoin with DeFi use cases within Plasma.
This makes Plasma a “Bitcoin-secured blockchain for stablecoins".

Security & Finality

Plasma emphasizes finality and security, tuned to payment workloads. Its consensus and architecture aim for strong protection against reorgs and double spends while maintaining high throughput.
The network launched mainnet beta holding over $2B in stablecoin liquidity shortly after opening.

Plasma Blockchain vs Alternatives: What Makes It Stand Out?

FeaturePlasma (XPL)Other L1 / L2
Stablecoin native designusually second-class
Zero fees for stablecoin transfersrare, or subsidized
BTC bridge (collateral)only some chains
EVM compatibilityyes in many, but with trade-offs
High liquidity early✅ (>$2B TVL)many chains struggle to bootstrap

These distinctions make Plasma especially compelling for institutions, stablecoin issuers, and DeFi innovators looking for scalable, low-cost, secure payments infrastructure.

Use Cases: What You Can Build with Plasma Blockchain

  • Stablecoin native vaults / money markets
  • Payment rails & cross-border settlement
  • Treasury and cash management flows
  • Bridged BTC-backed stablecoin services
  • DeFi primitives (DEX, staking, yield aggregation) optimized for stablecoins

If you’re building any product reliant on stablecoin transfers or needing strong collateral backing from BTC, Plasma offers a compelling infrastructure foundation.

Get Started with Plasma Blockchain: Key Steps & Considerations

  1. Smart contract migration: assess if existing contracts can port with minimal changes.
  2. Gas token planning: decide whether to use USDT, separate gas tokens, or hybrid models.
  3. Security & audit: focus on bridge logic, reentrancy, oracle risks.
  4. Liquidity onboarding & market making: bootstrap stablecoin liquidity, incentives.
  5. Regulation & compliance: stablecoin issuance may attract legal scrutiny.
  6. Deploy MVP & scale: iterate fast, measure gas, slippage, UX, security.
