Radius

Radius is a stablecoin-native settlement layer built for machine-to-machine micropayments. The company focuses on internet-scale payment flows such as per-request API billing, streaming payments, pay-per-use content, and autonomous agent commerce, with EVM-compatible smart contracts, sub-second settlement, and near-zero transaction costs.

Based in Cambridge, Massachusetts, Radius was founded in 2024 by a team with backgrounds spanning the Boston Fed, MIT Digital Currency Initiative, Circle, Bitstamp, Poloniex, and Zcash. The company positions Radius as infrastructure for the AI economy, where software agents need programmable, low-cost settlement that can move value at the same speed as data.

High-Level Overview

Radius is a settlement layer purpose-built for machine-to-machine micropayments and agentic internet commerce. Its core pitch is that current payment rails and most blockchains were built for human-paced transactions, not for API-level billing, autonomous software agents, or sub-cent usage-based payments. Radius is designed to support those workloads with stablecoin-denominated fees, near-zero costs, sub-second finality, and EVM compatibility for existing Solidity developer workflows.

What Radius Builds

The network is positioned as infrastructure for use cases such as real-time API metering, streaming payments, pay-per-visit content, and agent-to-agent service purchases. Radius highlights parallel sharded execution, linear scalability, and high throughput to make those payment patterns economically viable at internet scale. The company also emphasizes that fees are paid in stablecoins rather than a volatile native gas token.

Team and Background

Radius is based in Cambridge, Massachusetts and describes itself as built by a team with experience from the Boston Fed, MIT Digital Currency Initiative, Circle, Bitstamp, Poloniex, and Zcash. Public team materials name Robert Bench as Founder and CEO, with co-founders and leaders including Anders Brownworth, Tyler Frederick, Kevin Karwaski, and Madars Virza. This background is central to the company narrative around digital money infrastructure, parallel execution research, and stablecoin payments.

Developer Positioning

Radius presents itself as EVM-compatible infrastructure for developers building agentic payment systems. Its public materials point builders toward network configuration docs, JSON-RPC references, contract addresses, bridging guides, and example payment flows. The company also ties its positioning closely to AI-native commerce, arguing that future software systems will need settlement rails capable of handling frequent, low-value, autonomous payments.
