The Stellar Developer Meeting features the OpenSapplin team presenting Q4 2025 library releases: WAD for high-precision decimal arithmetic in Soroban smart contracts, fee abstraction for paying transaction fees with tokens like USDC instead of XLM, and the timelock module as the start of a governance package. These tools enhance developer experience, enable smart account functionality via relayers, and improve contract governance transparency and safety. The team highlights ongoing momentum and community adoption.
In this Stellar Developer Meeting, the OpenSapplin team reviews their Q4 2025 releases and 2025 achievements, including event participations at Meridian and Istanbul Blockchain Week. Osgon details the WAD module, a fixed-point decimal library using 18 decimals for deterministic, high-precision arithmetic in Soroban smart contracts, with operator overloading, truncation for predictability, phantom overflow handling, and safe token conversions. Bojan introduces the fee abstraction module, allowing users (classic or smart accounts) to pay transaction fees in non-XLM tokens via relayers and fee forwarder contracts, with permissionless and permissioned variants to support UX improvements and smart account initiation. He also covers the timelock module, the first in a governance package, which delays owner actions on contracts to enable user exits, promote transparency, prevent malicious takeovers, and chain operations sequentially. Future plans include voting extensions and governor modules in Q1 2026. The session emphasizes community value, documentation at docs.openseplin.com, and Discord support.
