Blockchain infrastructure upgrades tend to fall into two categories: the ones that move the needle and the ones that generate a press release. Injective’s Vulcan upgrade, version 1.20.0, appears to be the former.
The upgrade went live between June 4 and June 9, 2026, delivering a new oracle engine and a precompile that lets EVM smart contracts pull on-chain price data directly. The headline number: a 90% reduction in gas costs for oracle services.
For developers building on Injective, that is not a minor quality-of-life improvement. Oracle calls are a constant, unavoidable expense in DeFi applications, derivatives protocols, and anything touching real-world asset pricing. Cutting that cost by nine-tenths changes the math on what is economically viable to build.
What the Vulcan upgrade actually does
The core addition is a precompile that bridges EVM smart contracts to Injective’s on-chain oracle infrastructure. In plain terms: a Solidity contract can now read price feeds natively, without routing through clunky workarounds or paying the gas premium that came with the old architecture.
