Who is Range

Range is a leading blockchain intelligence and monitoring platform for the Solana and Cosmos ecosystems.

Range brings extensive experience in Rust development, as well as deep proficiency in L1 and cross-chain integrations. Our clients and trusted partners include the Solana Foundation, Circle, dYdX, Celestia, Squads, Osmosis, Noble, Cosmos Hub, and more.

Our products are natively cross-chain. To solve the frustration of tracking cross-chain transfers, we launched the first Cross-Chain Explorer - consolidating data from 50+ major ecosystems and 4 leading interoperability protocols, offering real-time insights into cross-chain transactions, all in one place. Developers and Product Teams can then leverage our API to integrate real-time transaction tracking and build custom analytics directly into their applications.

We provide critical infrastructure across the risk and security lifecycle to help organizations and users build and use cutting-edge financial applications safely:

• With its advanced explorer, Risk APIs, real-time monitoring and alerts, the Range Platform helps secure over $31 billion in assets.
• Range Trail, our cross-chain forensic wallet monitoring tool, is used by multiple teams to respond to incidents and identify stolen funds in security hacks.
• Our USDC Explorer is the primary explorer for Circle's CCTP protocol. It helps users track cross-chain stablecoin transfers daily across Ethereum, Solana, Base, Arbitrum, Polygon, Cosmos and many other ecosystems.
• Our IBC Rate Limit contracts secure every transaction across Cosmos’s Osmosis and Neutron chains, limiting the potential damage caused by a hack.
• Our Risk APIs form the backbone of the new Solana Transaction Security Standard, which Squads Protocol adopted to secure its users, who have over $10 billion in combined assets. Squads and other teams rely on our Risk API to secure more than $100 million in stablecoin transactions monthly, ensuring real-time risk assessment and proactive threat mitigation across the Solana ecosystem.
