Mintlayer (ML)

Overview

Mintlayer is a blockchain built to connect Bitcoin with digital assets and financial applications. Its native coin, ML, helps run the network: people use it to pay fees, create tokens, and take part in staking. Mintlayer describes its network as a Bitcoin sidechain and layer-two platform. In everyday terms, it is a separate blockchain designed to work closely with Bitcoin while handling features that Bitcoin’s base network was not built to provide on its own. (docs.mintlayer.org)

A central idea is the atomic swap. This lets two people exchange assets on different blockchains, such as BTC on Bitcoin and a token on Mintlayer. The exchange follows rules that allow both sides to complete the trade or reclaim their assets after a time limit. Mintlayer also supports tokens representing other kinds of value, from digital collectibles to financial assets. Together, these tools form its approach to Bitcoin-based decentralized finance, often called DeFi. (docs.mintlayer.org)

History & Team

From concept to mainnet

Mintlayer’s roadmap dates the project’s initial concept to 2020. Early work focused on a staking system, a Bitcoin-like transaction model, and a way for the two networks to exchange assets. The ML token was first issued on Ethereum in 2023. Mintlayer then launched its own mainnet on January 29, 2024, beginning the move toward ML as a native coin on its own blockchain. (mintlayer.com)

The project identifies Enrico Rubboli as its founder and Anna MacMillan as a co-founder. RBB LAB, led by Rubboli, has backed the development of Mintlayer’s open-source network. The team also includes contributors working on protocol engineering, wallets, token economics, and services for organizations building on the chain. (mintlayer.com)

Development has continued beyond the mainnet launch. The team introduced support for Bitcoin atomic swaps in a core-node release, expanded its Mojito wallet, and tested user-facing applications such as RioSwap and MintFun. These steps show how Mintlayer has grown from a network project into a broader set of tools and products. (mintlayer.com)

Technology & How It Works

A Bitcoin-like way to record assets

Mintlayer uses a UTXO model, short for “unspent transaction output.” Bitcoin uses this model too. Imagine receiving change after paying with cash: a transaction uses existing pieces of value and creates new pieces that can be spent later. On Mintlayer, token information can be included in these outputs, allowing users to issue and transfer assets through the network’s transaction system. Blocks are designed to arrive about every two minutes on average. (docs.mintlayer.org)

The chain uses proof of stake rather than Bitcoin’s proof of work. Participants lock ML in staking pools, and eligible pools produce blocks. A person who wants to operate a pool needs a pledge; someone with a smaller amount can delegate ML to an existing pool. Mintlayer’s consensus design selects block producers for time slots and favors the chain with the densest history of filled slots. (docs.mintlayer.org)

Swapping with Bitcoin

Mintlayer’s Bitcoin swaps use hash time-locked contracts, or HTLCs. In a swap, each side locks an asset under related cryptographic conditions. Revealing a secret to claim one asset makes it possible for the other side to claim the matching asset. If the exchange does not finish, time limits provide a path for the assets to be reclaimed. The BTC stays on Bitcoin until it is claimed there; the Mintlayer asset stays on Mintlayer until it is claimed on that chain. (docs.mintlayer.org)

Mintlayer’s base network favors defined transaction functions over a fully open-ended smart-contract system. Its supported functions include token operations, staking, multisignature controls, and swap-related tools. That design keeps common activities close to the transaction layer. For more flexible applications, the team has been developing ZK Thunder, a separate, Ethereum-compatible execution layer intended to work alongside Mintlayer. (docs.mintlayer.org)

Tokenomics & Utility

Supply and distribution

Mintlayer’s published economic model starts with 400 million ML allocated across sales, development, community incentives, reserves, marketing, and the team. Its stated supply cap is 600 million ML. The difference is intended to enter the system through block rewards over roughly the first decade of network operation. Some of the original allocation followed vesting schedules, which released tokens over time rather than all at once. (docs.mintlayer.org)

ML has several direct network uses. It can pay transaction and token-issuance fees, and staking it lets holders help support block production through a pool. The protocol also specifies ML charges for certain asset-management actions, such as changing a token’s supply or authority; these charges are burned under its published model. Mintlayer describes fee payment in other tokens as a future feature that would depend on whether block producers accept them. (docs.mintlayer.org)

These roles connect the coin to activity on the network. Creating assets calls for issuance fees, using the chain calls for transactions, and producing blocks calls for stake. ML can also be one of the assets exchanged for BTC through Mintlayer’s swap system. (mintlayer.com)

Ecosystem & Use Cases

Tokens, trading, and business tools

Mintlayer supports MLS-01 fungible tokens, whose units are interchangeable, and MLS-03 non-fungible tokens, whose units can be distinct. A fungible token might represent a payment asset or a share in a defined product. An NFT might record a unique item or certificate. Issuers can attach metadata so wallets and other applications can show information about an asset. (docs.mintlayer.org)

The ecosystem includes Mojito, a wallet for Mintlayer assets and network participation. RioSwap is being built as an interface for peer-to-peer Bitcoin atomic swaps, while MintFun gives users a simpler way to create fungible tokens. Both RioSwap and MintFun reached public testnet in 2025; the team’s roadmap sets out further work toward mainnet products. Mintlayer also provides developer tools, including a JavaScript software kit. (mintlayer.com)

Mintlayer Web Services focuses on tools for organizations issuing and managing assets. Its stated areas include property-related products, bonds, investor records, and reporting. This side of the ecosystem shows how the same token and transaction features can serve both individual users and institutions building financial products. (mintlayer.com)

Advantages & Challenges

Mintlayer’s main advantage is its close fit with Bitcoin. Its UTXO structure will be familiar to Bitcoin developers, while atomic swaps offer a way to exchange BTC for Mintlayer assets directly across the two chains. Native token issuance also gives developers a route to create basic assets without writing a complex contract for every token. Delegated staking lets people participate without operating their own pool. (docs.mintlayer.org)

The same design creates trade-offs. Mintlayer’s base-layer functions are more limited than those of general-purpose smart-contract platforms, making tools such as ZK Thunder important to its plans for more complex applications. A useful swap network also needs software that makes matching trades and completing cross-chain steps straightforward. RioSwap’s testnet work addresses that practical part of the system. Finally, staking-based block production depends on people continuing to operate pools and delegate to them. (mintlayer.com)

Where to Buy & Wallets

ML is available on Bitget, MEXC, and Gate, among the exchanges identified by Mintlayer. The project’s Mojito wallet supports native ML and delegation to staking pools. Mintlayer also offers full-node wallet software for people who want to run a node or manage a pool. Exchange deposits and withdrawals use particular networks, so the network selected for a transfer needs to match the receiving wallet’s address. (mintlayer.com)

ML was originally issued as an Ethereum ERC-20 token before moving to Mintlayer mainnet. On September 21, 2026, the team confirmed November 1, 2026 as the final deadline for migrating the original ERC-20 ML through its migration process. It also described plans for a new Ethereum representation connected through a future bridge. These are separate stages in the coin’s move from its original issuance to native network use.

Regulatory & Compliance

Mintlayer’s technology can support assets with very different legal roles. An ML coin used for network fees is different from a token that represents a bond or company share. In the United States, the Securities and Exchange Commission has stated that a security represented by a crypto asset remains subject to securities laws. In the European Union, the Markets in Crypto-Assets framework sets rules for many crypto-asset issuers and service providers, while an asset’s particular features affect how it is classified. Mintlayer Web Services describes issuer records, reporting, and access controls as parts of its institutional offering. (sec.gov)

ML itself has no established, project-wide halal or Shariah classification in Mintlayer’s published materials. The project has outlined tools for recording Shariah certifications on tokens and has listed an Islamic-finance certification platform on its roadmap. Those tools concern the assessment of particular issuers and products. Whether a use of ML meets Islamic finance principles depends on the transaction or product involved and the assessment applied to it. (docs.mintlayer.org)

Future Outlook

Mintlayer’s roadmap centers on making its existing technology easier to use. Planned work includes a mainnet release for RioSwap, broader token-creation tools, further development of ZK Thunder, and a bridge connecting Mintlayer with Ethereum-compatible networks. The team has also described continued work on wallet interfaces and services for asset issuers. These plans extend the core idea: use Mintlayer for Bitcoin-linked settlement and asset creation, then give builders practical ways to turn those functions into applications. (mintlayer.com)

The project’s lasting role will be shaped by how well those pieces work together. A blockchain can provide the rules for tokens and swaps; wallets, exchanges, developers, and issuers make those rules useful to people.

Summary

Mintlayer is a proof-of-stake blockchain designed around Bitcoin interoperability. ML supports its fees, token creation, and staking, while atomic swaps provide a route between native BTC and Mintlayer assets. With its mainnet operating and more applications in development, Mintlayer occupies a distinct place in the effort to build financial tools that connect directly with Bitcoin. (docs.mintlayer.org)
