PSA: Vyper versions 0.2.15, 0.2.16 and 0.3.0 are vulnerable to malfunctioning reentrancy locks. The investigation is ongoing but any project relying on these versions should immediately reach out to us.
Great news! We're excited to announce that @ethereumfndn (via @EF_ESP) has provided funding to support our mission. This grant covers a portion of our 2025 budget, bringing us closer to our goals for advancing secure and accessible smart contract development.
Vyper vulnerability post-mortem report regarding the events of this past week: hackmd.io/@vyperlang/HJU…
tl;dr -
versions affected: v0.2.15, v0.2.16, v0.3.0
vulnerability in brief: cross-function re-entrancy is possible on contracts compiled with the susceptible versions
We are proud to announce, after months of hard work, that Vyper 0.3.2 is released! 🎉🎉🎉
This long-awaited release brings two of the most sought-after features to Vyper: dynamic arrays & full ABI type support 🥳🥳🥳
However, first we have 3 disclosures that were fixed in 0.3.2
We are happy to announce that we have received a $50,000 USDC grant from the @ensdomains Public Goods Working Group to support Vyper's development. Thank you to the @ENS_DAO community for making this possible!!!
v0.3.5 of vyper is being released today! this is a small release which fixes some UX issues discovered shortly after the 0.3.4 release. thanks to several new contributoors as well for some docs updates! /
We are happy to announce that we've received a 50k MATIC grant from @0xPolygonFDN to help support Vyper's security! The funding will go towards implementing a definitional interpreter and differential fuzzing of the compiler
Vyper was awarded 250k OP from this rpgf round! Many thanks to the badge holders and others who have supported us along the way. We will continue working towards making vyper the best and most widely used smart contract programming language!
Vyper's selector table is highly optimized, possibly some of the most optimized code in any web3 compiler. It can save dozens to hundreds of gas before even entering any user code! Interested in how? You can thank "Sparse, Constant Time Jump Tables", pioneered by Vyper lead
🎉🎉🎉 Today we are releasing v0.3.0!!! 🎉🎉🎉
This version of Vyper has had a lot of hard work put into refactoring our legacy backend, which was blocking us from making more progress on much-requested features
Check out the release notes:
we would also like to extend special thanks to @CurveFinance and @newmichwill for extensive support over the years, as well as from @yearnfi and @LidoFinance. Vyper today would _really_ not be possible without them, and the latest investments in security would not either./
