Avalanche vs Unichain

Avalanche implements Snowman consensus on its C‑Chain (EVM) and runs a multi‑chain architecture with X‑Chain (UTXO) and P‑Chain (staking). Custom subnets allow projects like DeFi Kingdoms and Intain RWA to spin up their own validator sets with whitelisted tokens. The 2025 Banff hard fork added elastic subnets with dynamic validator staking for improved security sharing.

Unichain is an OP‑Stack Layer‑2 built by Uniswap Labs that employs a trusted‑execution‑environment (TEE) block builder to guarantee ordered execution free from MEV. Liquidity pools enjoy baked‑in sandwich protection, and the UNI token governs sequencer whitelists. The chain inherited native hooks from upcoming Uniswap V4, enabling dynamic fee models.
