December 2025 monthly summary for OriginTrail/dkg.js: Focused on stabilizing on-chain transaction costs and release hygiene. Delivered gas price estimation and transaction handling improvements with EIP-1559-style fee history retrieval, priority fee percentile management, retry logic, buffer tuning, and enhanced error handling, including enforcement of sufficient token allowances. Also completed targeted fixes from code reviews to harden the gas/allowance logic under fluctuating network conditions. Finalized release maintenance by bumping the library version to 8.2.2 across package.json and package-lock.json, ensuring a consistent production release. This work reduces failed transactions due to mispriced gas, improves reliability, and strengthens the library for production use.
