# Glossary

> Protocol, trading, and control terminology.

**Active liquidity**\
Liquidity from positions whose half-open range contains the current tick.

**Confidential address**

A public swap address derived from program address, domain, signer, and a private factor. Its relationship to the signer is not disclosed in ordinary public state.

**Caller**\
The account or program that directly invokes the current AMM function.

**Claim**\
The transaction that converts a pending public `SwapOutput` into token records.

**Compliance record**\
An encrypted record owned by the hardcoded investigator recipient and created by mint or swap.

**Confidential**\
Record ownership or attribution omitted from the ordinary public ledger view. Public metadata and correlation may still reveal related activity.

**Current tick**\
The discrete price interval associated with the stored square-root price.

**Fee growth**\
Cumulative input-token fees per unit of active liquidity.

**Fee pips**\
Pool fee parts per million. A value of 3000 is 0.30 percent.

**Finalize**\
The on-chain stage that runs futures, checks public state, and updates mappings.

**Freezelist**

An operator restriction tree used by Shield Swap non-inclusion proofs. Mint checks signer, owner recipient, and withdrawal. Collect checks NFT owner and withdrawal. Claim checks signer.

**Frozen position**\
A position whose liquidity has been removed and whose position operations are blocked until admin unfreeze.

**Gross liquidity**\
Total position liquidity referencing a tick boundary.

**Inside fee growth**\
Fee growth attributed to the interval between a position's lower and upper ticks.

**Investigator key**\
The address hardcoded as owner of compliance records. The corresponding view key can decrypt them.

**Liquidity epoch**\
A period with a particular active-liquidity set. Mint, increase, decrease, freeze, or crossing can change the set.

**Liquidity net**\
Signed active-liquidity change associated with crossing an initialized tick upward.

**Mapping**\
Public consensus storage keyed by a Leo value.

**Position NFT**\
The Leo record that carries authority over a public position token ID. It is not an ARC-721 token.

**Price limit**\
A directional square-root-price bound for a swap or hop.

**Private**\
An Aleo input or record visibility class that omits the value from ordinary public arguments.

**Protocol fee**\
Configured fraction of the swap fee accumulated separately for admin collection.

**Q128.128**\
A fixed-point interpretation with 128 whole and 128 fractional bits. Square-root prices and fee growth use `u256::U256` in this form.

**Raw amount**\
Token amount in the token program's native base units.

**Record**\
An owner-bound encrypted Aleo state object that can be consumed and replaced.

**Signer**\
The top-level account that authorized and signed the transaction.

**Shield transaction**

A transaction constructed by a Shield Swap integration to trade, claim output, or manage liquidity.

**Slot**\
The mutable per-pool state containing price, current tick, active liquidity, fee values, and nearest initialized ticks.

**Square-root price**\
The pool's Q128.128 square root of the native base-unit token ratio.

**Tick**\
A discrete price boundary and, when initialized, a stored liquidity and fee-accounting node.

**Token ID**\
A field value used to identify a dynamically dispatched token program.

**Tokens owed**\
Public position accounting for settled principal and fees available to collect.
