Liquidity layer

The liquidity layer handles DIEM staking and inference capacity allocation. It works independently of the agent launchpad — any wallet or contract can use it directly.

Contracts

Contract	File	Purpose
Pool	core/Pool.sol	Staking, capacity accounting, reserve, borrow, yield
Vault	core/Vault.sol	Holds DIEM, drives Venice staking, manages unstake queue

Flow

Gateway reads capacityToday(user) → Venice API key limit

Pending entry

DIEM deposited today activates tomorrow. This matches Venice's own timing — stake today, capacity tomorrow. Your shares balance updates immediately; activeShares catches up at the next UTC day boundary.

Capacity sources

capacityToday(user) sums three independent buckets:

Source	How to get it	Resets
reserved	reserve(amount)	Never (until you change it)
purchased	purchase(amount) — pay USDC	Each UTC day
borrowed	borrow(amount) — repaid via capacity lock	Each UTC day

USDC yield

Revenue from purchase() flows into a sellPerShare accumulator (MasterChef pattern). Call claim() to collect accrued USDC at any time.
