XPR Description
Overview
Proton (XPR Network) (XPR) is the native token of XPR Network, its own EOSIO-derived delegated-proof-of-stake layer-1 blockchain (formerly Proton Chain), not an ERC-20 or SPL token on Ethereum or Solana.
The chain is designed as a layer-one proof-of-stake network offering instant transactions and on-chain identity, aimed at developers building tokens, NFTs, and exchanges, with a stated focus on cross-border payments.
Value Proposition
XPR Network differentiates itself by combining feeless transactions with human-readable addresses, ISO 20022 payment-messaging compatibility, and built-in on-chain KYC, targeting compliant payment use cases over general-purpose smart contracts.
Token Basics
XPR functions as both a utility and governance token: holders stake it to secure the network and use it to vote on who validates transactions.
- Staking XPR and voting for Block Producers through continuous approval (stake-weighted) voting
- Paying for network resources — CPU, NET, and RAM bandwidth and storage allocations, following an EOSIO-style resource model
Tokenomics
XPR has no fixed maximum supply, and net emission is inflationary, growing over time through ongoing Block Producer reward issuance on top of an initial fixed distribution.
- Circulating supply: approximately 28.65 billion XPR (as of 2026-09-02)
- Market capitalization: approximately $79 million (as of 2026-09-02)
- All-time high: $0.00819911, with price down 66.06% from that level (as of 2026-09-02)
- Initial supply: 10 billion XPR, distributed via airdrop, with no fixed cap added since
Launch & Funding
XPR launched via a 1:1 airdrop to holders of the MTL (Metal) and LNX (Lynx) tokens in March 2020, rather than through a traditional ICO.
The XPR Network mainnet went live in April-May 2020, built through collaboration between Metallicus Inc. and Lynx Wallet with the stated goal of bridging traditional finance and blockchain payments.
Blockchain & Consensus
XPR is not deployed as a token on Ethereum, Solana, or another external chain — it runs on its own layer-1 blockchain, an EOSIO-derived delegated-proof-of-stake (DPoS) network.
The top 21 Block Producers validate transactions, elected by XPR holders through continuous approval (stake-weighted) voting.
Team
XPR Network (originally Proton) was founded by Marshall Hayner and Glenn Mariën.
- Marshall Hayner (CEO) previously founded QuickCoin and Block.io, built one of the first Bitcoin wallets on Facebook, and collaborated with Stellar
- Glenn Mariën (CTO) created Dogechain.info, Dogecoin's online wallet, and has more than 10 years of experience as a full-stack developer
Two companies, Metal (Metallicus/Metal Pay) and Lynx (Lynx Wallet), jointly developed Proton.
Issuing Organization
Metallicus Inc., founded in 2016, is the parent company and core developer behind the XPR Network ecosystem.
Metallicus also operates Metal Pay, a blockchain-based payment processing platform, and Proton Loan, and holds a permanent seat on the XPR Network Consortium governance body.
Governance
XPR Network is governed on-chain through delegated proof-of-stake: XPR holders vote for Block Producers using continuous approval (stake-weighted) voting.
- The top 21 Block Producers validate transactions and run the network
- A Consortium of six key Block Producers acts as a steering committee over roughly 40 active Block Producers
- The Consortium oversees technical development, governance, marketing/growth, and grant distribution
Roadmap
As of May 22, 2026, XPR Network reiterated its focus on feeless, scalable transactions, human-readable addresses, ISO 20022 payment-messaging compatibility, and on-chain KYC.
- Continued technical work on cross-chain bridging infrastructure
- A renewed push on the "XPR DeID" decentralized-identity standard, aimed at replacing long wallet addresses with simple handles
- DeFi activity on ecosystem protocols including MetalX and LOAN reported growing as of June 22, 2026
Frequently Asked Questions
What is Proton (XPR Network)?
Proton (XPR Network) (XPR) is the native token of XPR Network, its own layer-1 blockchain (formerly "Proton Chain"), an EOSIO-derived delegated-proof-of-stake network. It is not an ERC-20 or SPL token native to Ethereum or Solana, though bridged wrapped versions exist on those chains. The chain offers feeless transactions and on-chain identity for developers building tokens, NFTs, and exchanges.
What consensus mechanism does XPR Network use?
XPR Network uses delegated proof-of-stake (DPoS), an EOSIO-derived model in which the top 21 Block Producers validate transactions. XPR holders elect these Block Producers through continuous approval (stake-weighted) voting, giving token holders direct on-chain influence over who secures the network.
What is XPR used for?
XPR is a utility token used to stake and secure the network, vote for Block Producers, and pay for network resources such as CPU, NET, and RAM bandwidth and storage allocations, following an EOSIO-style resource model. It also functions as a governance token through Block Producer voting.
Does XPR have a maximum supply?
XPR has no fixed maximum supply. It launched with an initial supply of 10 billion XPR, and net emission is inflationary, growing over time through ongoing Block Producer reward issuance. Circulating supply stood at approximately 28.65 billion XPR, with a market capitalization of approximately $79 million, as of 2026-09-02.
How was XPR launched?
