October 2025 monthly summary for boundless project (boundless-xyz/boundless). This period delivered security hardening, deployment improvements, and observable reliability gains across vulnerability fixes, infrastructure upgrades, and new capabilities. Security hardening (V-BND-VUL) implemented non-canonical signature rejection, unified client signature validation, in-assessor request validation, non-zero constructor checks, and partial payment support, reducing attack surface and hardening contracts. Infrastructure and deployment enhancements aligned with main branch, improved indexer logging, environment/address updates, admin provisioning, and forceEC2 prover recreation to improve reliability and speed of iteration. Monitoring and alarms were added for expired requests, increasing operational visibility and quicker remediation. Solidity version 0.8.26 was enforced to ensure compatibility and security, and gas checks for optional callbacks were introduced to prevent runtime failures. New capabilities include depositTo for directed deposits and an override IPFS gateway, alongside incremental updates such as CACHE_DATE bump and related deployment refinements. Overall impact: stronger security posture, more reliable deployments, and expanded business capabilities with improved routing and governance tooling.
