The platform operates using [Avalanche](https://iq.wiki/wiki/avalanche) [consensus mechanisms](https://iq.wiki/wiki/consensus-mechanism) and supports functions such as [digital asset](https://iq.wiki/wiki/digital-assets) transactions, [smart contract](https://iq.wiki/wiki/smart-contract) deployment, subnet infrastructure, and digital identity systems. Its architecture includes support for private and public blockchain environments intended for use by financial institutions, fintech companies, and other organizations operating within digital finance ecosystems.

The network is designed with a multi-chain structure that separates core functions across different chains, including transaction processing, [smart contract](https://iq.wiki/wiki/smart-contract) activity, and network validation.\n\nThe protocol supports the deployment of [decentralized applications](https://iq.wiki/wiki/decentralized-application) through [Ethereum Virtual Machine (EVM)](https://iq.wiki/wiki/ethereum-virtual-machine-evm) compatibility and includes functionality related to digital identities and permissioned [blockchain](https://iq.wiki/wiki/blockchain) environments. Its subnet architecture allows organizations to create independent blockchain environments with customized operational parameters.\n\nMETAL serves as the native token of the network and is used for [staking](https://iq.wiki/wiki/staking), validator participation, and transaction-related functions within the ecosystem. The protocol also incorporates [ISO 20022](https://iq.wiki/wiki/iso-20022)-related messaging compatibility intended to support interaction with existing financial communication standards.

The development capitalizes on the extensive experience of its advisory board, who offer over a century of traditional banking experience. The platform was established to empower financial institutions with [blockchain](https://iq.wiki/wiki/blockchain) capabilities, allowing secure and efficient management of transactions and identity verifications through advanced cryptographic techniques. [\\[2\\]](#cite-id-i1HmGJegAZNTEPfd)  [\\[4\\]](#cite-id-2VqKLdR8poloHqqk)  [\\[6\\]](#cite-id-Nq203E8G9x0hCZuZ)  [\\[8\\]](#cite-id-TRHGMdq7OAIouyKI) \n\n## Technology & Architecture\n\nThe Metal Blockchain is structured on multiple chains to accommodate diverse operations:\n\n* **A-Chain (XPR Network)**: Optimized for fast payments and [DeFi](https://iq.wiki/wiki/defi) operations using the Antelope framework, allowing [smart contract](https://iq.wiki/wiki/smart-contract) capability.\n* **C-Chain (Contract Chain)**: [EVM](https://iq.wiki/wiki/ethereum-virtual-machine-evm)-compatible for creating and managing [Solidity](https://iq.wiki/wiki/solidity) [smart contracts](https://iq.wiki/wiki/smart-contract), enabling easy [dApp](https://iq.wiki/wiki/decentralized-application) development.\n* **P-Chain (Platform Chain)**: Coordinates validators and subnets management, allowing creation and tracking of custom subnets.\n* **X-Chain (Exchange Chain)**: Facilitates creation and exchange of new assets, ensuring seamless cross-subnet transfers.\n\nThe platform's extensible architecture ensures secure monitoring and scalable performance, with a capacity to process 4,500 transactions per second on its subnets. [\\[1\\]](#cite-id-kDvJTW4zjdaV7M7T)  [\\[4\\]](#cite-id-2VqKLdR8poloHqqk)  [\\[7\\]](#cite-id-OndQQ4i7GMZxzoZn)  [\\[6\\]](#cite-id-Nq203E8G9x0hCZuZ) \n\n## Tokenomics\n\nThe native currency of Metal Blockchain, METAL, is a scarce asset with a total capped supply of 666,666,666 tokens. It has several allocations:\n\n* **Metal Foundation**: 142,333,333 METAL\n* **Founders**: 71,000,000 METAL\n* **MTL Conversion**: 120,000,000 METAL\n* **Staking Rewards**: 333,333,333 METAL\\[1].\n\nMETAL tokens are utilized for [transaction fees](https://iq.wiki/wiki/transaction-fee), [staking](https://iq.wiki/wiki/staking) to secure the network, and providing a unit of account among subnets. The fees involved in transactions are burnt, introducing a deflationary mechanism under which the token supply decreases over time, adding intrinsic value. The staking rewards criteria involve a variable annual rate between 10 to 12%, with validators requiring a minimum stake of 2,000 METAL.
