Perpetual Futures on Sei

Sei is an EVM-compatible L1 with a block time around 400 milliseconds and a native on-chain order book as a built-in primitive. The "native order book" means smart contracts on Sei can list and match orders using chain-level modules rather than implementing matching logic entirely in Solidity. This design was aimed at reducing gas overhead for order-heavy applications like perp DEXes.

Orderly on Sei

Orderly Network lists Sei among its seventeen deployment chains. Orderly functions as infrastructure: it provides a shared order book and liquidity layer that frontend applications build on top of. The Sei deployment means Orderly-powered frontends can settle trades with Sei's native confirmation speed while routing liquidity through Orderly's shared pool.

PerpFinder observes Orderly's Sei deployment handling a fraction of the total Orderly volume, which itself is smaller than the dedicated perp DEXes on Arbitrum or Hyperliquid. The chain's perp market is nascent relative to Ethereum rollups.

DefiLlama's Sei chain page shows TVL in the $200-400 million range as of mid-2026, modest compared to Arbitrum or Base.

The native order book: practical impact

Sei v2 launched EVM compatibility in 2024, bringing the developer tooling benefit of Solidity compatibility while retaining the native order book module. The intent is that order book applications can use chain-native matching (cheaper) instead of implementing it in a smart contract (expensive). For a perp DEX with high order throughput, this can reduce per-order gas costs by a meaningful factor.

The Sei documentation describes the parallelized EVM execution and native order matching in detail. Block times below 400ms with instant finality (no challenge period) put Sei in a similar category to Solana for latency-sensitive trading.

What holds Sei back

The EVM compatibility arrived late — most perp DEX teams had already committed to Arbitrum, Base, or Solana deployments before Sei's EVM launch. Switching chains requires auditing new deployments and rebuilding liquidity bootstrapping campaigns. The network effect cost of migration is high.

Sei also lacks a flagship perp DEX of its own. Arbitrum has GMX, Solana has Jupiter Perps, Sui has Bluefin. Sei's perp trading story is currently "Orderly deploys here too," which is thin differentiation for attracting traders.
