2nd June 2026 – Injective has proposed the Injective Vulcan upgrade (IIP-650), its biggest mainnet upgrade yet, as it seeks to become the settlement layer for onchain finance.
High Signal Summary For A Quick Glance
- Injective’s Vulcan mainnet upgrade (IIP-650) proposes a rebuilt oracle engine that cuts oracle gas usage by 90%, with new Pyth Network Pro and Seda oracle types for institutional-grade pricing
- The upgrade strengthens canonical Circle USDC standards through tighter token factory metadata controls and expands tokenized RWA market support via Morpho integration
- If the governance vote passes, the chain will halt at block 169,334,500 on June 4, 2026 and resume running v1.20.0 with lower fees, leaner execution, and hardened bridge security
- INJ stakers who have four days to vote on the proposal through Injective’s Cosmos SDK governance process
- DeFi developers and protocols building on Injective who will gain access to cheaper oracle calls, a unified EVM oracle precompile, and expanded RWA market infrastructure
The proposal went live for governance voting on June 2, 2026. If passed, the chain will halt at block height 169,334,500 on June 4 and resume running v1.20.0. INJ stakers have four days to vote through Injective’s standard Cosmos SDK governance process.
Vulcan touches nearly every core layer of the protocol. The changes span oracle infrastructure, stablecoin issuance, RWA market expansion, bridge security, and transaction costs.
What Changes With the Vulcan Upgrade
Before vs after the Injective Vulcan mainnet upgrade (v1.20.0 / IIP-650)
Oracle Engine Gets a 90% Gas Cut
The centerpiece of the Injective Vulcan upgrade is a rebuilt oracle engine. According to the proposal specs on Polkachu, oracle gas usage drops by 90% under the new architecture.
The upgrade also adds two new oracle types. Pyth Network Pro brings institutional-grade pricing with broader coverage. Seda oracles add a second source for low-cost, high-frequency data feeds.
On top of that, a unified oracle precompile now gives EVM smart contracts direct access to Injective’s canonical price data. Developers building on Injective’s EVM layer no longer need custom bridges to read oracle feeds.
For traders and protocols running perpetuals or options, cheaper oracle calls translate directly to lower execution costs per trade.
Stablecoin and USDC Standards Tighten
Vulcan strengthens stablecoin issuance on Injective through tighter token factory metadata controls. The upgrade also advances canonical Circle USDC standards on the chain.
Standardized USDC issuance reduces fragmentation. Instead of multiple wrapped versions competing for liquidity, canonical USDC creates a single source of truth.
Injective launched native USDC support in May 2026. The chain’s stablecoin market cap currently sits at roughly $13.98 million according to DefiLlama. Vulcan’s metadata controls could accelerate that growth.
RWA Markets Expand via Morpho
The new oracle stack directly enables expanded tokenized RWA markets on Injective. With cheaper and more reliable price feeds, protocols can list real-world asset pairs without prohibitive gas costs.
The proposal also references Morpho integration for onchain credit and lending. Morpho is a lending protocol known for its modular risk management. Its presence on Injective could open the chain to institutional credit markets.
Injective has been building toward RWA support since the Volan upgrade in January 2024. That release introduced a native RWA module. The Injective Vulcan upgrade extends that foundation with the infrastructure needed to run those markets at scale.
Injective Vulcan Upgrade Cuts Fees and Hardens Bridges
Beyond oracles and RWAs, the Injective Vulcan upgrade delivers several execution-layer improvements. Compute per transaction drops, and bridge costs decrease.
Bridge security receives multiple hardening measures. These include stricter address validation, safer concurrent processing, and removal of the deprecated Hyperlane module. Ledger multisig support with EIP712 signatures adds an extra layer of security for bridge operators.
Minor governance cleanups round out the proposal. These include INJ minimum notional parameters and delegation receiver adjustments.
Community Response and Market Context
Early community reactions on X are strongly positive. Users highlight the 90% oracle gas cut and the “settlement layer” framing as key narratives.
“Vulcan is really a massive leap. This is exactly how you build the premier settlement layer,” wrote user @kingsonnofweb3 in reply to the announcement thread.
“Vulcan sounds solid, cutting oracle gas by 90% is exactly what we need for real world assets to scale properly,” added @MacroBombastic.
INJ has shown strength heading into the proposal. The token gained roughly 90% through May 2026, reaching highs near $5.80. Injective TVL sits at approximately $11.9 million to $12.2 million, according to DefiLlama data from May 31.
No major publications such as CoinDesk or The Block have covered the Vulcan proposal yet. The story broke less than 24 hours ago.
Timeline: Injective’s evolution from a Cosmos-based derivatives chain to an institutional settlement layer for RWAs, stablecoins, and onchain finance
Canonical Chain mainnet launches
Injective officially launches its mainnet, introducing staking, governance, derivatives trading infrastructure, and the foundation for its Cosmos-based financial ecosystem.
Camelot upgrade expands DeFi capabilities
The Camelot upgrade introduces enhanced CosmWasm smart-contract functionality, atomic order execution, and CW20 token support, accelerating Injective’s transition into a full-scale DeFi platform.
Volan upgrade introduces RWA infrastructure
The Volan upgrade debuts Injective’s native real-world asset framework, enhanced IBC interoperability, and scalability improvements aimed at institutional adoption.
Altaris upgrade boosts scalability
Injective deploys Altaris, significantly improving transaction throughput, execution speed, and overall network efficiency while enhancing core infrastructure performance.
Native EVM mainnet goes live
The MultiVM upgrade enables unified WASM and EVM development with shared liquidity, sub-second block times, and ultra-low fees across the Injective ecosystem.
IIP-619 strengthens EVM infrastructure
The IIP-619 upgrade introduces real-time EVM scaling enhancements and payment infrastructure improvements designed for high-frequency financial applications.
Vulcan mainnet proposal enters governance
Injective submits Proposal 650 (Vulcan), introducing a next-generation oracle engine, canonical USDC acceleration, expanded RWA infrastructure, lower execution costs, and enhanced bridge security.
Governance voting period begins
INJ stakers participate in the standard Cosmos governance process to determine whether Vulcan will become the next major network upgrade.
Vulcan activation scheduled
If approved, the network will halt at block height 169334500 and restart on version 1.20.0, activating the largest Injective upgrade focused on stablecoins, RWAs, and institutional finance.
What Comes Next for Injective
The governance vote runs through approximately June 6. If the proposal passes, validators will coordinate the chain halt at block 169,334,500 on June 4 at around 14:00 UTC.
Once the Injective Vulcan upgrade activates, developers and protocols gain access to cheaper oracles, standardized USDC tooling, and expanded RWA market infrastructure. The upgrade requires no user migration.
Some details remain open. Named RWA issuers onboarding via Morpho have not been disclosed yet. Additional buyback parameter changes are not detailed in the current proposal thread. Voters can review the full proposal at Injective Hub or the Polkachu mirror.
