XRP Ledger Privacy Solution: Boundless Completes First Native ZK Validator Deployment on XRPL

April 15 — Boundless and XRPL Commons announced the successful completion of the first native deployment of a zero-knowledge (ZK) validator on the XRPL network. The RISC-V-powered validator now operates directly on the chain, making XRPL the first public blockchain to offer programmable privacy as a ledger-native feature with built-in compliance controls. Per the announcement, the two organizations spent six months on the integration and jointly developed the Smart Escrow transaction type, complete with programmable release conditions. Developer toolkits and testnet environments are now available. Smart Escrow is slated to launch in Q2 2026 and will require a valid ZK proof to transfer funds. Smart Vault will follow, adding pre-settlement KYC checks and sanctions screening for every transaction, plus supporting limited disclosure to regulatory bodies. “XRPL was built from the start for institutional finance,” said Odelia Torteman, Head of Enterprise Adoption at XRPL Commons. “By

Polymarket Reviewing Its Developer Program, Several Mirror Apps Openly Teach Users to "Trade with Insider Traders"

**April 15th Update** Prediction market platform Polymarket has kicked off a review of third-party startups in its Builders Program, launched last November to let external developers build trading apps on its infrastructure. Some 200 developers have joined so far, eligible for up to $2.5 million in grants and weekly rewards—but a key issue has emerged: top participants in the program are all building copy-trading apps. These apps curate trading accounts with abnormally high win rates, flag suspicious timing/trade amounts, and let users copy trades with one click. Kreo’s selling point is helping users “spot insider traders faster than others,” while Polycool lists an “Insider Trading Guide for Polymarket” on its site, noting: “This isn’t the stock market—betting on non-public info won’t land you in jail; decentralized prediction markets have totally different rules.” The Builders Program has driven Polymarket’s trading volume from $100 million last November to over $600 million
