# Wallets and vaults

> Display, hold, and compose Overpass yield tokens.

Wallets and vaults can use Overpass yield tokens as productive SPL assets.

## Wallet integration

Wallets should display yield-token positions with enough source context for users to understand what they hold.

Recommended display fields:

* token name and symbol
* wrapper mint
* underlying mint
* source protocol
* source pool
* redeemable value per token
* total wallet balance
* estimated underlying value
* creator and protocol deposit fees
* source-pool warnings

Avoid displaying a yield token as a generic stablecoin or generic wrapped token. It is a source-pool-specific claim.

## Vault integration

Vaults and indexes can hold yield tokens as portfolio assets. This lets strategies allocate to lending pools while keeping the position transferable and composable.

Before adding a yield token to a vault, evaluate:

* source-pool withdrawal liquidity
* cap behavior
* accounting stability
* oracle health
* concentration limits
* route availability for rebalancing
* whether the wrapper is verified or canonical

## Treasury use

Treasuries can use Overpass to allocate idle assets into lending yield while keeping a tokenized position on-chain.

Treasury integrations should define:

* allowed source protocols
* allowed underlying assets
* maximum allocation per source pool
* minimum withdrawal-liquidity requirements
* risk escalation rules
* exit routes

## Collateral markets

Collateral markets need more conservative handling.

Before accepting an Overpass yield token as collateral, evaluate:

* source protocol risk
* source-pool liquidity and utilization
* oracle dependencies
* redemption delay and failure modes
* price feed design
* liquidation route availability
* wrapper registry status
* maximum loan-to-value and caps

An external oracle or risk engine may be appropriate for collateral use. The Overpass mint and redeem path uses source-pool accounting, but lending markets need independent collateral valuation and liquidation assumptions.

## Displaying APY

Use precise labels:

* realized APY or NAV growth is backward-looking
* source-pool APY is forward-looking
* projected values are estimates, not guarantees

Never imply that historical NAV growth guarantees future yield.
