Nibiru Chain Launches Sai Perpetual Futures Exchange on Testnet (Q1 2026)

Nibiru Chain is making a calculated move into the perpetual futures market with Sai, a fully on-chain perpetual futures exchange scheduled to go live in early 2026. 

The platform targets one of the most competitive segments in decentralized finance, but comes with a specific infrastructure advantage: it runs natively on Nibiru's high-throughput Layer 1, combining EVM and Wasm execution in a single environment.

Sai is in active development with an expected launch in early 2026, and the team has already finalized a smart contract audit on the core protocol logic while the web application remains under active development. 

That audit milestone matters. It signals the project is past the conceptual stage and into hardened pre-launch territory.

Key Takeaways

• Sai supports up to 100x leverage on certain assets, with market, limit, stop-loss, and take-profit orders available in a fully on-chain, non-custodial experience.
• Trading fees are set at 0.10% for both opening and closing positions, calculated on total position size rather than collateral alone.
• Nibiru's own X profile confirms Sai as a perpetual futures exchange launching Q1 2026, with oracle-powered pricing covering broader markets beyond just blue-chip assets.

What Sai Actually Is and How It Works

Sai is not a fork of an existing perp protocol, and the team is deliberate about that distinction. 

Sai pairs two building blocks to keep markets fair and responsive: oracles, which are independent price feeds that track real-world markets, and an automated market maker that provides liquidity traders can always trade against instead of waiting for a counterparty.

Sai settles trades using reference prices from highly liquid crypto exchanges, similar to GMX, with pricing supported by the Nibiru Oracle, which aggregates prices from leading exchanges like Binance, Bybit, and OKX through Nibiru's decentralized validator network. 

This approach eliminates internal price manipulation risks and keeps the system anchored to real market conditions, which is a direct response to one of the most common criticisms of on-chain derivatives platforms.

The Fee Model and Liquidity Structure

The fee design on Sai is structured to balance trader costs against liquidity provider incentives. The open fee sits at 0.10% (10 basis points) charged on total position size when entering a trade, with the same rate applied on close, and a much smaller 0.01% trigger fee on automated orders to cover execution costs.

Where the fee distribution gets interesting is in how it flows. The vault, which represents liquidity providers, receives 25% of all closing fees to support platform stability, while the protocol receives the remaining 75% of closing fees and 100% of open fees, with a portion allocated to governance stakers. 

High-volume traders can unlock lower fee tiers through a points-based system, and the referral program adds another layer of discount on top. For new platforms trying to attract liquidity, this kind of layered incentive structure is typical, but Sai's specifics are more transparent than most at this stage.

Leverage, Liquidations, and Risk Controls

Leverage on Sai is the ratio of position size to deposited collateral, meaning depositing $100 to open a $500 position equals 5x leverage, with each market having its own maximum leverage parameter displayed in the UI.

Liquidation mechanics follow a maintenance margin model. If a trader's total equity, calculated as profit and loss plus collateral, falls below the maintenance margin, the position becomes eligible for forced closure, with the Sai interface displaying a liquidation price to show where that threshold sits. 

On the liquidation penalty side, a 10% penalty is deducted from remaining collateral upon liquidation, split between a closing component and a trigger component, with payments prioritized first to the vault, then to the liquidator, and finally to the protocol. 

That priority waterfall is a meaningful protection for liquidity providers and a sign the protocol has thought through its risk architecture carefully.

The Broader Nibiru Context and 2026 Roadmap

Sai does not exist in isolation. It is the flagship application for Nibiru's push to make the chain the primary destination for on-chain derivatives trading. 

Based on Messari, Sai's 2026 roadmap includes a refined trading interface, DeFi integrations connecting with other applications for swaps and routing, automated strategy vaults, a CEX-like account experience with gasless trades, and multichain USDC deposits from Ethereum, Base, and other supported networks without manual bridging.

That multichain collateral feature deserves specific attention. One of the persistent friction points in on-chain perp trading is the capital movement required to fund positions. If users can deposit USDC directly from Ethereum or Base without touching a bridge manually, the onboarding barrier drops significantly. 

The team is also led by Nibiru founder and CEO Unique Divine, who brings a background in applied mathematics, machine learning, and prior experience at IBM and Sommelier Protocol, according to Messari's coverage.

Conclusion

Sai represents Nibiru Chain's most significant product bet to date. The protocol has cleared a smart contract audit, established a concrete Q1 2026 target, published detailed fee and liquidation mechanics, and outlined an ambitious roadmap through the rest of 2026. 

The combination of oracle-settled pricing, competitive fees at 0.10% per side, up to 100x leverage, and native Nibiru chain performance positions Sai as a credible challenger in the on-chain perps market. 

What separates it from generic launches is the infrastructure specificity: every component, from oracle aggregation to fee distribution to liquidation waterfall, is documented and audited. Whether the mainnet execution matches the testnet ambition is the question that 2026 will answer.
