Arbitrum vs Katana

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.

Katana is a DeFi Layer-1 chain incubated by Polygon Labs and GSR, designed to maximize on-chain liquidity and real yield. Its Vaultbridge system redeploys bridged assets like ETH and USDC into yield strategies on Ethereum, while Chain-owned Liquidity (CoL) channels 100% of sequencer fees into deep, protocol-controlled liquidity pools. Katana’s native AUSD stablecoin, backed by US Treasuries, powers lending markets and DEX liquidity with off-chain yield incentives.
