Opening the Playbook: Why We're Open-Sourcing Casper's Core DeFi Infrastructure

Casper Network has open-sourced four production DeFi infrastructure repositories—a naming service (CSPR.name), a Uniswap V2-style DEX (CSPR.trade), a liquid staking protocol, and an EIP-712 typed signature crate—all security-audited by Halborn and live on mainnet. The move aims to close the gap between Casper's open-source protocol layer and its application layer, giving builders production-tested reference code ahead of the v2.2.0 mainnet upgrade on March 23rd. The repositories come from three different organizations, reinforcing a shared-commons approach to ecosystem development.
