Glossary

Sei-specific

Sei: high-throughput L1 with both Cosmos and EVM execution layers on the same chain
pacific-1: Sei mainnet (chain id 1329)
atlantic-2: Sei testnet (chain id 1328)
Native SEI: the gas token. Same on Cosmos and EVM sides.
WSEI: Wrapped SEI (ERC-20). Required for any DEX that needs an ERC-20 base. Wraps 1:1.
usei: Cosmos-side SEI denom. 1 SEI = 1,000,000 usei
Staking precompile: built-in contract at 0x0000000000000000000000000000000000001005. Lets EVM contracts call Cosmos staking (delegate, undelegate, redelegate).
Distribution precompile: built-in at 0x0000000000000000000000000000000000001007. For pulling staking rewards.
Oracle precompile: built-in at 0x0000000000000000000000000000000000000091. For USD prices. Not currently used by JellyPad.

Liquid staking token (LST): receipt token issued for staked principal. Tradeable while still earning yield.
jpSEI: JellyPad's in-house LST. ERC-20, 18 decimals, exchange-rate-bearing. Backed by JellyPadStaker.sol.
spSEI: Splash's LST. Used by JellyPad's v3 deployments; replaced by jpSEI in v4.
iSEI: Silo's LST. Cosmos-side only, 6 decimals, not usable from EVM.
Exchange rate: how much SEI 1 unit of LST is worth. Grows over time as rewards compound in.
Instant unstake: convert LST to native SEI without the 21-day lock, paying a fee. JellyPadStaker: 0.5–4% tiered based on buffer ratio.
Slow unstake: standard Cosmos unbonding queue. 21-day wait, no fee.

Buffer: native SEI on the staker contract's balance. Pays instant-unstake exits.
Target buffer: the level the protocol aims to maintain. Static by default; dynamic when dynamicMode = true.
Effective target: max(static, supplyRatio × supply, pendingSlowSei, demand × multiplier) when dynamic mode is on.
Pending slow: sum of jpSEI burns whose 21-day unbond hasn't completed. Buffer must always be ≥ this.
Trailing demand window: rolling 7-day sum of instant-unstake gross volume, in 24-hour buckets.
Rebalance: permissionless rebalance() queues an undelegation when buffer dips below rebalanceTriggerBps × effectiveTarget.

Saphyre: Sei's main DEX. Rebrand of DragonSwap V2. Uniswap V2 fork.
DragonSwap V2: original brand. Same contracts as Saphyre.
LP (liquidity provider): someone who deposits two tokens into a pool and earns swap fees.
LP shares / LP tokens: receipt for an LP position. Burning them = forfeiting the underlying liquidity forever.
addLiquiditySEI: Saphyre version of Uniswap's addLiquidityETH
swapExactSEIForTokens: Saphyre version of swapExactETHForTokens
Constant-product AMM: x × y = k formula used by V2

Bonding curve: programmatic price curve where supply is sold along a predetermined formula.
Graduation: a curve-based token transitioning to a permanent on-chain DEX pool.
Mcap (market cap): total supply × current price. JellyPad's graduation check uses a simplified realSeiReserves × seiUsdPrice.
Pump.fun: the canonical Solana memecoin launchpad. JellyPad is modelled on it with the yield twist.

Curve phase: pre-graduation. Trading goes through JellyPadToken.buy() / .sell().
Post-graduation: after curve fills. Trading happens on Saphyre's (jpSEI, MEME) pair.
LP burn: at graduation, the LP receipt is sent to 0xdEaD. Mathematically unrecoverable.
Operator share: portion of the 1% protocol fee that flows to treasury. Default 50%, capped at 70%.
Yield bonus: the extra return long holders receive from the pool's jpSEI side compounding.
