# glossary Key terms used throughout Durianfun docs. ### Bonding curve A mathematical price curve where token price increases as more tokens are bought, implemented via virtual reserves on a constant-product invariant. Durianfun's curve is designed to give early buyers a meaningful discount while ensuring deep liquidity by graduation. ### Creator rebate The 0.167% share of every bonding-phase trade that is transferred directly to the token's creator wallet, instantly, in KUB. ### Graduation The event when a token's bonding curve has raised enough liquidity to deploy a permanent AMM. Happens atomically in a single transaction — bonding curve ends, AMM begins. ### AMM (Automated Market Maker) A smart contract pool that trades two assets using a mathematical formula (in Durianfun's case, x·y=k). Post-graduation, Durianfun tokens trade exclusively on their own AMM. ### Constant product (x·y=k) The mathematical invariant used by Durianfun's AMM: reserve\_A × reserve\_B always stays constant after trades (minus fees retained in pool). Same model as Uniswap V2. ### Sealed liquidity Liquidity that cannot be withdrawn by anyone. Durianfun's AMMs have no `removeLiquidity` function — once tokens + KUB enter the pool, they stay forever. ### Price-aligned graduation Durianfun's AMM opens at exactly the bonding curve's final price, preventing the "price cliff" that typically happens at launch on other platforms. Combined with the 10-block cooldown, this eliminates graduation-time sniper MEV. ### Factory A smart contract that deploys new tokens + markets. The Durianfun factory maintains the registry of all tokens launched through it. ### Market Short for `BondingCurveMarket` — a per-token contract that handles trading during the bonding curve phase. ### MEV (Miner / Maximal Extractable Value) Profit extractable by reordering or inserting transactions. Classic example: sandwich attacks. Durianfun mitigates graduation-MEV with a 10-block cooldown. ### Cooldown A 10-block (\~50 second) window right after graduation during which no trading is allowed on the AMM. Prevents snipers from racing to be first on the fresh pool. ### LP (Liquidity Provider) fee A trading fee that stays inside the pool rather than being distributed to token holders. Durianfun's post-graduation AMM keeps 0.10% of every swap in the pool, deepening liquidity over time. ### PPM (parts per million) The unit used for fee rates on-chain. 10,000 PPM = 1%. Durianfun's bonding fee of 10,670 PPM = 1.067%. The AMM fee of 4,000 PPM = 0.40%. ### dKUB / dKUB2 Test-only ERC-20 base tokens used by Durianfun's test environment (`FactoryDV25`). NOT real money — only for sandboxed trading experiments. ### Treasury The wallet that collects Durianfun's platform fees. Currently a multisig at `0x46799c319EB17cE9f52C2Ff22959C67bad92Dd0b` — all 4 factory contracts point here. ### Graduation bonus A one-time payout at graduation: 50 KUB to treasury + 10 KUB to the token creator. Automatic, atomic, paid in the same tx as graduation. ### Slippage The difference between the expected trade price and the actual fill price, caused by price moving while the tx is pending. Durianfun's `minOut` parameter lets you cap slippage — reverts the tx if price moves too far. ### Rebate Synonym for "cashback on trading fees". Durianfun's creator rebate is a per-trade cashback to the token creator. --- # Agent Instructions This documentation is published with GitBook.
