June 2025 Mintlayer Development Update
June 1, 2025

As we move deeper into 2025, the Mintlayer team continues to refine the core infrastructure and tools that will power Bitcoin-native DeFi. This month, much of our work has focused on wallet optimizations, dApp-ready features, and preparing our Token Factory for broader access for other ecosystem projects.

Wallet Enhancements & SDK Integration

Significant progress was made on the Mojito Wallet, particularly the browser extension. Key improvements include:

  • Optimized network request handling through a new backend layer for improved responsiveness
  • SDK integration to handle both internal and external transactions
  • Early-stage development of token swapping functionality based on order books
  • Continued UI/UX refinement for a smoother experience

These changes aim to provide seamless, dApp-ready interaction with Mintlayer’s features — including upcoming Atomic Swaps and RWAs. 

JavaScript SDK: Evolving Developer Toolkit

Our JavaScript SDK is under active development to support full-stack dApp development. We’re continuously expanding its capabilities to cover everything developers need to integrate wallets, build transactions, and support cross-chain features like HTLC swaps (Atomic Swaps).

Token Factory in Beta

The Token Factory is currently in beta testing — providing a user-friendly interface to create and manage MLS-01/MLS-03 tokens. Wallet integration is underway, and real-world usage through ecosystem partner dApps will help refine the final release.

Cross-Chain Bridge

Key updates to the Mintlayer ↔ Ethereum Bridge this month include:

  • SDK integration to streamline Mojito Wallet connections
  • Support for Mintlayer-to-Ethereum asset swaps in final testing 
  • Ongoing optimization and codebase refactoring

These upgrades aim to make cross-chain interactions more secure, efficient, and user-friendly. Helping to build a link from Mintlayer to Ethereum and Bitcoin.  

Core Node

Work continues on the next Mintlayer Core Node release, which will include performance improvements and features for enhanced testnet functionality. A new version is expected in the coming months.

Wrapping Up

From tokenization tools to swap-ready wallet improvements, the Mintlayer development stack is advancing rapidly. These upgrades are paving the way for ecosystem partners to build Bitcoin-native dApps, decentralized exchanges, and institutional-grade token issuance — all while preserving the core principles of self-custody and trustless design.

Your Address Checks Itself

One typo in a bech32 address gets caught, located, and corrected before signing. On 0x chains, almost any lowercase string is a valid address. Security at Mintlayer starts at the format level.

An Append-Only Attestation Layer for AI Decisions

Proofs and attestations only become evidence when they live somewhere an auditor can find them, with a timestamp nobody disputes and no way for the operator to revise the collection. Bitcoin-anchored infrastructure provides exactly that.
