Injective unveils Vulcan upgrade, enhancing EVM access for developers

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.

Vulcan integrates two oracle providers, Pyth Pro and SEDA, both oriented toward institutional-grade data coverage. The combination is pointed squarely at two fast-growing segments: tokenized real-world assets and lending protocols. Morpho, a lending integration, is specifically cited as a beneficiary of the new oracle infrastructure.

The upgrade also tightens up token factory functionality, with improved support for canonical USDC. The upgrade introduces stricter validation rules and adds EIP-712 Ledger support for bridges. EIP-712 is a standard that enables structured, human-readable transaction signing, which reduces the risk of users inadvertently 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, specifically for one of the most frequently used operations in DeFi.

The Pyth Pro integration is worth noting separately. Pyth has become a dominant oracle provider across major DeFi ecosystems, and the Pro tier is oriented toward institutional users who need high-frequency, high-fidelity data. Pairing that with SEDA, which brings its own data verification infrastructure, gives Injective a credible pitch to institutional builders exploring tokenized RWA markets.

Context: building on top of a busy 2025

Vulcan does not arrive in isolation. It builds directly on two prior milestones that reshaped Injective’s technical foundation.

The first was the Volan upgrade, which introduced Injective’s native RWA module, the first of its kind on the network. The second was the native EVM mainnet launch in November 2025, which opened Injective to the much larger universe of Ethereum-native developers. Vulcan is the follow-on that makes that EVM environment meaningfully better, giving those developers cheaper, more direct access to price data.

What this means for developers and investors

For institutional builders specifically, the Pyth Pro and SEDA integration is a credibility signal. The fact that Injective is now wired to institutional-grade data providers makes it a more serious candidate for projects involving tokenized securities, commodities, or structured credit products.

The market’s immediate reaction told a familiar story. INJ moderated in price after the upgrade launched, a textbook sell-the-news response. That behavior reflects profit-taking by traders who positioned ahead of the announcement rather than any fundamental reassessment of the upgrade’s value.
