Neura V1 at a glance

The hybrid pool design: two curves, fee tiers, surge fees and a built-in oracle.

Neura V1 is a hybrid constant-function market maker. We studied the ideas that have proven themselves across DeFi — the simplicity of constant-product pools, the capital efficiency of stable curves, flash swaps, on-chain TWAPs — and implemented them in our own reference contracts. Public review, executable tests and independent audits are separate steps; design intent is not proof of safety.

Building blocks

FeatureWhat it doesWhy it matters
Volatile curve$x \cdot y \ge k$Works for any pair, liquidity across all prices
Stable curve$x^3y + xy^3 \ge k$Near-zero slippage for pegged pairs
Fee tiers0.01% · 0.05% · 0.30% · 1.00%Match the fee to the pair's risk
Surge feeExtra fee on 2nd+ swap in a blockCharges any later swap; no guaranteed MEV protection
Volatile oracle primitiveRaw-reserve ratios accumulated on updatesConsumers must review observations and manipulation risk
Flash swapsBorrow output, repay in the same txArbitrage and liquidations without capital
Locked minimum liquidityFirst 1,000 LP units burnedRaises inflation cost; stable pools lock a larger decimal-aware floor

Pool identity

A pool is unique per (token0, token1, curve, fee tier). ETH/USDC can have a 0.05% volatile pool and a 0.30% volatile pool; USDC/USDT would typically use the 0.01% stable pool.
