The “inEVM” roll-up via @arbitrum Orbit
In May 2024, @injective announced a collaboration with Arbitrum Nitro/Orbit to build an EVM-compatible roll-up called inEVM, enabling Ethereum, Cosmos, Solana interoperability
The announcement stated: “By customizing Arbitrum’s unique Orbit stack, Injective’s inEVM is now even more bespoke…”
The aim was: allow Ethereum-style contracts to deploy, benefit from Injective’s speed/IBC/Cosmos modules, while using Orbit’s infrastructure
So in this phase: inEVM = an Orbit-based EVM roll-up built in partnership 🧵👇 (1/4)
The shift to a native EVM layer on Injective’s main chain
Later, on Jan 29 2025, Injective announced the launch of a native EVM layer embedded directly into its L1 chain (Cosmos/Tendermint-based) rather than relying on an external roll-up.
On July 2 2025, the native EVM testnet went live, enabling Ethereum-compatible apps directly on Injective L1
The key difference: This architecture is built “solely on Injective’s infrastructure” instead of an external roll-up.
They’re pursuing a Multi-VM strategy: EVM and WASM on one unified chain
(2/4)
Why this matters & how to think of it
Stage 1 (@arbitrum Orbit‐Rollup): provided a quick path to an EVM-compatible environment using Arbitrum tech
Stage 2 (Native EVM): represents the strategic end-state: full EVM compatibility built into Injective’s architecture for better cohesion and performance
Importantly: you’re not wrong, both phases exist. It’s just that the roll-up (inEVM) via Orbit was the earlier or parallel approach; then they shifted (or added) the native EVM layer
(3/4)
This @injective EVM originally “came from” @arbitrum Orbit. But today, the strategic core is their own native EVM embedded into the L1, with Orbit as an earlier phase (and possibly still used for some app-specific chains) (4/4)
