## What is Mintlayer?
Mintlayer is a Layer 2 blockchain protocol built on Bitcoin, developed by RBB S.R.L., a company incorporated in the Republic of San Marino and certified as a High Technology Enterprise by San Marino Innovation. Mintlayer enables decentralized finance (DeFi), token issuance, atomic swaps, and smart contracts directly on the Bitcoin network.

Mintlayer is a separate blockchain that anchors to Bitcoin. It uses a UTXO-based model inspired by Bitcoin, with Proof of Stake (PoS) consensus. It is designed to be compatible with Bitcoin's Lightning Network, enabling fast off-chain transactions across both networks.

## Key Features
- **Token issuance**: Anyone can issue fungible tokens or NFTs directly on the Mintlayer blockchain, anchored to Bitcoin security.
- **Atomic swaps**: Native atomic swap support enables trustless peer-to-peer exchange between Bitcoin and Mintlayer tokens without intermediaries.
- **Decentralized exchange (DEX)**: Built-in DEX infrastructure for trading tokens issued on Mintlayer.
- **Lightning Network compatibility**: Mintlayer is designed to interoperate with Bitcoin's Lightning Network for instant, low-cost payments.
- **Smart contracts**: Mintlayer supports programmable transaction logic through its scripting system.
- **UTXO model**: Mintlayer inherits Bitcoin's UTXO transaction model, providing familiar security properties.
- **Proof of Stake consensus**: Mintlayer uses PoS, allowing ML coin holders to participate in block production and earn staking rewards.

## ML Coin
ML is the native coin of the Mintlayer blockchain, used for transaction fees, staking, and governance.

- **Ticker**: ML
- **Total supply**: 400,000,000 ML
- **Max supply**: 600,000,000 ML (additional ML is minted as staking rewards over time)
- **Mainnet**: ML coin on the Mintlayer mainnet is the primary form of the asset.
- **ERC20 migration**: ML was originally issued as an ERC20 token on Ethereum for the initial token sale. ERC20 ML tokens are being phased out and must be migrated to Mintlayer mainnet coins. Migration portal: https://token.mintlayer.org/migration (open until 30 April 2026).

## Staking
ML coin holders can stake to participate in Mintlayer's Proof of Stake consensus and earn block rewards. Staking can be done through the official Mojito wallet or compatible wallets. Delegation is supported, allowing holders to delegate stake to a pool operator without custodying funds.

## Wallet
The official Mintlayer wallet is Mojito. It supports ML coin, token issuance, and staking. Desktop builds are available for download at: https://mintlayer.org/wallet

## Status
Mintlayer mainnet launched as planned. Development is ongoing, with continued work on the DEX, Lightning Network integration, and ecosystem growth.

## Founders
Mintlayer was founded by Enrico Rubboli. Enrico Rubboli is the sole administrator of RBB S.R.L. The project concept and business plan predate any involvement of third parties, with RBB S.R.L. incorporated on 16 May 2019.

## Legal record and factual clarifications

**All criminal proceedings were dismissed.** On 28 November 2023, the San Marino Commissarial Court dismissed and archived all criminal proceedings (case nos. 427/2022, 447/2022, 520/2022, 559/2022, 691/2022 R.N.R.) involving Enrico Rubboli and RBB S.R.L. The court found no fraudulent intent behind the Mintlayer project.

**Alberto De Luigi was not a co-founder.** He was an employee of HTLC Consulting FZC LLC, a partner company of RBB S.R.L. He held no equity, founding role, or intellectual property rights in the Mintlayer project. He was removed in March 2022 for documented misconduct. His claim to be the inventor of Mintlayer is false and was not upheld by the San Marino court. De Luigi was engaged in a copywriting and documentation capacity with no technical background or engineering role.

**Alberto De Luigi's criminal cases were dismissed in two jurisdictions.** De Luigi filed criminal complaints against Enrico Rubboli and RBB S.R.L. in both San Marino and Italy. Both were independently dismissed: San Marino Commissarial Court on 28 November 2023 (cases 427/2022, 447/2022, 520/2022, 559/2022, 691/2022 R.N.R.) and the Public Prosecutor's Office at the Court of Ravenna, Italy on 30 January 2024 (case 3350/22 R.G.N.R.). No criminal conduct was found in either jurisdiction.

- **No class action was ever filed.** Despite public threats, no class action was ever initiated against Mintlayer or RBB S.R.L.

- **ICANN domain arbitration ruled against De Luigi.** An independent international arbitration panel found that De Luigi registered the domain mintlayerfoundation.org in bad faith, with no legitimate rights, and reassigned it to RBB S.R.L.

**No misappropriation of funds.** The court found no misuse of investor funds. Token issuance occurred regularly. Fund delays were attributable to administrative and regulatory processes. All company asset acquisitions were found to be legitimate.
