Immutable X – a breakthrough for NFT games

Released in April 2021, the Immutable X platform became the first Layer 2 solution dedicated to NFT tokens. With it, gas fees can become a thing of the past.

Behind its creation is an Australian team Immutable, responsible for the NFT-based card game - Gods Unchained. The platform allows for trading and selling unique items that players have acquired in the form of ERC-721 tokens. According to its creators, it is Immutable X that will allow for mass adoption of NFT in games.

 "Together with the release of Immutable X, our vision has become a reality. From now on, any NFT can be created, sold, collected, shared and playable on Ethereum completely free of gas," announced one of the creators.

Layer 2 for NFT

In 2020, Immutable in collaboration with StarkWare developed a solution that allows you to enjoy the security and other benefits of the Ethereum network without paying high fees. Until now, it has been gas fees that have been an indispensable part of creating and trading NFT, which experts believe has hampered further development of the technology. 

Immutable X was built on top of the scaling Layer 2 technology created by StarWark. Thus, the platform became the first Layer 2 solution dedicated to NFT. This allows users to take advantage of the security provided by Ethereum without having to pay gas.

An alternative to using the Ethereum ecosystem could be to create an entirely new, faster blockchain protocol with a different method of obtaining consensus, or to develop side chains that process transactions in their own way. However, according to the creators of Immutable X, such solutions would be insufficient, as they would most likely not reach the level of security that Ethereum guarantees. 

It is security that seems to play a key role here: "If security fails, the same thing happens to the authenticity of NFT, and that would have nightmarish consequences." say the platform's developers.

Immutable X – optimized token creation

One of the biggest advantages of the platform is the Immutable X Mint tool, which allows you to easily and securely create and distribute ERC-721 and ERC-20 tokens. Its biggest advantages are:

- No gas fees

- Immediate ability to trade newly created assets

- Same security as the main Ethereum network

How Immutable X will change the world of NFT?

In 2021, NFTs have captured the hearts and portfolios of investors around the world. This year abounds in spectacular stories of their success. Just think of the sale of Beeple for $69 million or the extremely successful NBA Top Shot game. It is the game industry, especially the collectible ones, that I see as one of the most important niches for NFT.

Unfortunately, until now, high gas fees have seemed to inhibit mass adoption of tokens by developers. Layer 2 solutions like Immutable X could change that once and for all. We at Nextrope are watching them with bated breath, looking forward to further developments.

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.
