# Vault

*[Documentation index](/llms.txt) · [Full index](/llms-full.txt)*

The Predict vault holds accepted quote assets and takes the opposite side of every trade. `predict.move` owns pricing and trading orchestration; `vault.move` is the state machine for balances, exposure, mark-to-market liability, max payout, and settled-oracle compaction.

LPs interact with the vault through `predict::supply` and `predict::withdraw`, which mint and burn `PLP` shares. See [Predict](/onchain-finance/deepbook-predict/contract-information/predict) for those public liquidity entry points.
