EVM & Tooling Alignment
Port existing Ethereum smart contracts using Solidity, common SDKs, and standard wallet libraries. Network gas is used purely as a permissioned metering unit with no exposure to public markets.
Token Standards Support
Full compliance with the ERC-20 standard for fungible tokens, alongside support for ERC-721, ERC-1155, and ERC-4626 for advanced tokenized vaults and financial constructs.
Programmable Logic
Embed institutional compliance directly into code. Smart contracts enforce whitelisting, jurisdiction filters based on KYC attributes, and conditional Delivery-versus-Payment (DvP) settlement.
On-Chain Representation of Off-Chain State
Off-Chain Custody & Legal Framework
Term sheets, custody agreements, trust deeds
Ethstable ERC-20 Smart Contract
Zero-Knowledge Privacy
Ethstable supports zk-SNARKs and shielded transactions, allowing participants to prove transaction validity without revealing counterparty identities or transfer amounts to the public ledger.
- Orion and Tessera Subgroup Isolation
- Selective Disclosure via Viewing Keys
- Off-chain Proof Generation
Mandatory HSM Integration
To protect network consensus, all validator nodes are required to secure their signing keys within physical Hardware Security Modules (HSMs) certified to military-grade standards.
- FIPS 140-2 Level 3 Certification
- Physical Tamper “Zeroization” Sensors
- Inter-node mTLS via Istio Service Mesh
Cross-Border Payments
Tokenized fiat currencies enable near-instant settlement between participating banks, reducing correspondent banking friction.
Treasury Management
Corporates can hold multi-currency balances on-chain, with programmable sweeps, escrow, and liquidity management logic.
Tokenized Deposits
Banks can issue tokenized deposit claims or money market funds, with on-chain subscription, redemption, and reporting.
Commodity Financing
Commodity-backed tokens with embedded transfer restrictions can streamline collateral management and settlement in trade finance.
