Ráneum
Zero Knowledge Optimistic Rollup
Layer-2 for Securities and NFTs
Securities & NFTs
Upstream runs on Ráneum mainnet trading securities (ERC-20) and NFTs (ERC-721) with 2-second transaction finality and zero gas fees
Secure
A commit-chain providing Ethereum-based finality which aids recovery in case of catastrophic failure
ETH Compatibility
Developers run unmodified EVM contracts and Ethereum transactions on layer-2 and leverage Ethereum’s layer-1 security
Fees
Ráneum deployments generate trading fees that collateralize RÁNEUM tokens
AMM
Ráneum runs an Automated Market Maker inside a Solidity-based transparent orderbook on Upstream
Payments
Ráneum smart contracts gain fiat on-ramp to US Dollars and an inter-chain bridge that accepts USDC from Ethereum
Founders
Ráneum is built by Horizon Fintex, with a world-class team of researchers, engineers, and Ethereum enthusiasts

Goddess of the Sea
In Norse mythology, Rán is a goddess of the sea associated with a net which she uses to bring seagoers together
Integrations
Ráneum integrates with Ethereum and a growing list of EVM smart contract applications and services
Ethereum
Ráneum operates an Ethereum layer-1 smart contract where it publishes its layer-2 transaction hashes as rolling attestations to the state of the chain
Upstream
Ráneum runs the complete set of Ethereum smart contracts used to operate the Upstream stock and NFT exchange for ERC-20 and ERC-721 issuance and secondary trading
KYCWare
Ráneum runs an Ethereum smart contract registry for publicly-anonymous identities that allow key pair-based accounts make public claims on layer-1 and layer-2 about the legitimacy of their ownership
Protocol
Ráneum implements the IBFT 2.0 Proof of Authority protocol with immediate finality, delivering Byzantine fault tolerance by operating multiple validators. To achieve resilience and high availability, validators and their constituent parts - compute, storage, networking and data resources - are distributed across physically and logically separated, sub 2ms low latency regional zones. Each validator zone comprises of multiple datacenters with independent power source, network and cooling. In addition, to facilitate comprehensive disaster recovery in the event of a regional zone failure, Ráneum employs a DRaaS which replicates validators to separate global locations.
Wallet
Ráneum shares the same wallet framework as Ethereum layer-1 which means that wallets on Ráneum mainnet can be used and shared with Ethereum mainnet using MetaMask.
Dora - Explorer
Dora is the Ráneum blockchain explorer. All transactions, securities and NFTs are rendered in a familiar, understandable layout with full, immutable public access.
Bridge
Ráneum operates an ERC-20 bridge smart contract on Ethereum layer-1 which operates in the same manner as other layer-2 chains by holding on layer-1 and minting & burning on layer-2.
Token
RÁNEUM, the Ráneum token is deployed on Ethereum. The token can be purchased directly on the RÁNEUM ERC-20 smart contract. Approved deployments on Ráneum generate fees that are trustlessly bridged to Ethereum to forever collateralize RÁNEUM.
Issuance
RÁNEUM operates a public mint() function on the Ethereum mainnet that requires ETH to be supplied to acquire 1 token. Tokens can be purchased using MetaMask.
Governance
RÁNEUM token holders will be eligible to propose and vote on the deployment of new smart contracts on Ráneum.
Yield
RÁNEUM tokens are collateralized with a share of the fee revenues from smart contracts operating on Ráneum. Collateral deposits via the fee-payment bridge-transfer can be made by any RÁNEUM token holder, anytime.
Developer
Ráneum is a community, and we want you to join Rán on her layer-2 voyage.
Submit Proposal
Any RÁNEUM token holder can propose an Ethereum layer-1 published and verified smart contract for deployment on Ráneum.
FAQ
The Ráneum support center answers as many of your questions as possible.
