Katana vs Sui

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.

Sui employs an object‑based data model and Narwhal/Tusk DAG consensus to execute independent transactions in parallel, giving near‑instant finality. Programmability uses the Move‑based Sui language with object ownership, enabling upgrades without storage migrations. The network supports sponsored transactions, letting dApps pay gas on behalf of users—a boon for mobile onboarding.
