Glossary

Definitions of the main terms used in Overlayer's protocol and VISION documentation.

Assets and yield

Term	Meaning
Underlying stablecoin	The stablecoin backing an Overlaid Asset family. For example, USDC is the underlying stablecoin of C+ and sC+.
Overlaid Asset	The liquid, transferable, non-rebasing representation of a supported stablecoin position. Holding it alone does not distribute protocol staking yield.
Staked Overlaid Asset	A share-based representation used to participate in the yield allocated to an asset family's staking position. For example, sC+ is the staked representation of C+.

The underlying stablecoin, base asset and staked representation serve distinct functions within the same asset family.

Term	Meaning
Backing	The on-chain position supporting outstanding Overlaid Asset supply.
Isolated backing	Separate backing and accounting for each asset family, rather than a shared collateral pool.
Non-rebasing	Token balances do not automatically increase as the backing generates yield.
Conversion ratio	The amount of base Overlaid Assets represented by one staked token. For example, a ratio of 1.10 C+ per sC+ means that 100 sC+ represents 110 C+.

Yield allocated to staking changes the amount represented by each share, rather than increasing the holder's number of staked tokens.

Term	Meaning
Staking ratio	The proportion of an asset family's base-token supply participating in staking, measured in base-asset units.
Overyield	The concentration effect created when yield generated by a broader backing base is allocated across a smaller amount of staked capital.
Performance fee	The portion of generated yield retained before the remaining yield is allocated to stakers. It is not charged as a percentage of deposited principal.
OVER	Overlayer's governance and ecosystem coordination token. It is separate from the assets backing Overlaid Assets and does not provide an entitlement to their staking yield.

Overyield depends on lending returns, staking participation and applicable fees.

For the mechanisms, see Staked Overlaid Assets and Yield & Overyield.

VISION and points

Term	Meaning
VISION	Overlayer's first mainnet Farming Season, through which eligible participation generates points used for OVER allocation.
Farming deposit	The additional deposit of an eligible asset into a Farming position to generate points. It is separate from minting or staking an Overlaid Asset.
Base Staking Points — BSP	Points generated by eligible Farming deposits according to deposited value, point rate and elapsed time.
Boost	A percentage increase applied to BSP production. Active boost percentages add together.
Additional Points	Points earned through mechanisms such as referrals, team leadership and selected ecosystem activities. Boosts do not apply to them.
Total Score	The combined score from staking points, including applicable boosts, and Additional Points. It is used for rankings and allocation calculations.

Staking yield and VISION points are separate systems: participating in one does not automatically enroll a position in the other.

Term	Meaning
Season Average TVL	The time-weighted average of global outstanding Overlaid Asset supply over the full season, counting each base Overlaid Asset nominally as $1.
Reward Pool	The amount of OVER allocated to VISION based on the final Season Average TVL.
Final Allocation	A participant's score-based OVER allocation plus any individual or team prizes, before Claim Game choices.
Claim Game	The post-season choice between Fast Claim and Long-Term Vesting, determining how an allocation becomes claimable, vested, burned or redistributed.

The Reward Pool determines the amount available for the season; a participant's score and prizes determine their Final Allocation.

For calculations, see How Points Work and Reward Pool & Season TVL. For release options, see Claim Game & Vesting.

NFTs and boosts

Term	Meaning
OG boost	The BSP bonus associated with eligible OG NFT ownership, recognized across supported chains for the same wallet.
Utility NFT	An NFT staked to activate a BSP boost on a specific chain. A wallet can activate one Utility NFT per chain.
Origin NFT	The base Utility NFT tier: Shrimp Origin, Dolphin Origin or Whale Origin.
Entropy NFT	The upgraded Utility NFT created through Maelstrom by combining and burning three Origin NFTs of the same type and chain.
Special NFT	An NFT providing an individually defined BSP boost through a separate slot, alongside the wallet's Utility NFT on that chain.

NFT boosts affect point production, not the staking yield of Overlaid Assets.
