Arbitrum vs Injective

Arbitrum One and Nova are optimistic rollups using Nitro fraud proofs that compress transactions into calldata submitted to Ethereum. The Orbit toolkit lets projects deploy their own Arbitrum Orbit chains with configurable permissions. ARB token governance manages the 3 000‑plus validator whitelist and a 1 billion‑dollar ecosystem grant fund.

Injective is a Cosmos‑SDK Layer‑1 with on‑chain order books, zero‑gas trading and a frequent batch auction that mitigates MEV. Its built‑in Ethereum bridge lets users bring ERC‑20s without custodial risk, and the WasmX module supports CosmWasm smart contracts. INJ holders can stake or participate in governance that controls upgrades like the 2024 Volan hard fork which added liquid staking.
