Glossary

LBF (Lanca Bridging Framework) — decentralized cross-chain liquidity framework enabling value movement between networks with high capital efficiency and security.

Parent Pool — central liquidity pool (Master chain) that accepts LP deposits, performs batch withdrawals, and manages Child pool target balances.

Child Pool — local pool on a destination network providing instant settlement liquidity and participating in IOU-based rebalancing.

LancaBridge — smart contracts through which users initiate and complete cross-chain transfers.

ConceroRouter / Concero V2 Messaging — secure cross-chain message & instruction transport used by LBF.

ConceroPriceFeed — price oracle for fair cross-asset settlement calculations.

LancaKeeper — automated operator handling periodic tasks: liquidity snapshots, batch deposits, batch withdrawals, and withdrawal finalization.

Rebalancer — independent participant who supplies capital to deficit pools and extracts from surplus pools via an IOU system in exchange for rewards.

IOU (I-Owe-You Token) — tokenized claim issued when a Rebalancer deposits into a deficit pool; redeemable from a surplus pool (subject to Surplus status) for underlying assets + fee.

targetBalance — liquidity goal for a pool assigned by the Parent Pool based on network activity and algorithmic metrics.

activeLiquidity — working capital of a pool: balance - rebalancingFees; used to classify Surplus/Balanced/Deficit.

Liquidity Utilisation Ratio (LUR) — (Inflow + Outflow) / targetBalance; activity metric.

Net Drain Rate (NDR) — (Outflow − Inflow) / targetBalance; liquidity stress metric.

Liquidity Health Score (LHS) — aggregate health metric combining LUR and NDR (0.7/0.3 weighting in the initial iteration).

Progressive Reward Model — sub-linear, time-sensitive bounty curve for Rebalancers, DAO-configurable and designed for sustainable incentives during extended deficits.
