Injective's Vulcan mainnet upgrade, version 1.20.0, went live between June 4 and June 9, 2026, delivering a 90% reduction in gas costs for oracle services and a new precompile that lets EVM smart contracts pull on-chain price data directly. The upgrade integrates institutional-grade oracle providers Pyth Pro and SEDA, targeting tokenized real-world assets and lending protocols.
What the Vulcan upgrade actually does
The core addition is a precompile that bridges EVM smart contracts to Injective's on-chain oracle infrastructure. A Solidity contract can now read price feeds natively, without routing through workarounds or paying the gas premium of the old architecture. Vulcan integrates Pyth Pro and SEDA, both oriented toward institutional-grade data coverage, with Morpho cited as a beneficiary of the new oracle infrastructure.
The upgrade also tightens token factory functionality with improved support for canonical USDC, adds stricter validation rules, and introduces EIP-712 Ledger support for bridges. EIP-712 enables structured, human-readable transaction signing, reducing the risk of users signing malicious bridge transactions.
Why oracle costs matter more than most people realize
Injective is a Layer 1 blockchain that natively supports both EVM and WASM execution environments, with built-in financial primitives and shared liquidity. Vulcan layers cost efficiency on top of that for one of the most frequently used operations in DeFi. The Pyth Pro integration is notable because Pyth has become a dominant oracle provider across major DeFi ecosystems, and the Pro tier is oriented toward institutional users needing high-frequency, high-fidelity data. Pairing that with SEDA gives Injective a credible pitch to institutional builders exploring tokenized RWA markets.
Context: building on top of a busy 2025
Vulcan builds on two prior milestones: the Volan upgrade, which introduced Injective's native RWA module, and the native EVM mainnet launch in November 2025, which opened Injective to Ethereum-native developers. Vulcan makes that EVM environment meaningfully better by giving developers cheaper, more direct access to price data.
The market's immediate reaction saw INJ moderate in price after the upgrade launched, a textbook sell-the-news response reflecting profit-taking by traders who positioned ahead of the announcement rather than any fundamental reassessment of the upgrade's value.
