The first share-based DeFi protocol on ApeChain

Unlock the FullPotential of APE

PrimalFi is the first DeFi liquidity layer on ApeChain that replaces traditional staking yield with an index-based system where protocol-wide rewards drive all value accrual.

prAPE Model

Users deposit APE and receive prAPE representing a proportional share of the protocol reserves.

Index-Based System

Value changes are driven exclusively by the Liquidity Index, not staking rewards or inflation.

About Primal Protocol

A liquid stakingliquidity protocolfor ApeChain

PrimalFi allows users to stake APE into a fully on-chain liquidity system while receiving prAPE, a liquid asset representing ownership inside the protocol.

Instead of using rebasing or manual reward claiming, PrimalFi uses an indexed accounting model where protocol growth is reflected globally through liquidityIndex expansion.

As rewards enter the system, the value backing every prAPE position increases automatically, creating a scalable liquidity layer for ApeChain DeFi.

Smart Contract Architecture

Indexed liquidityaccounting engine

Underlying Liquidity

The protocol tracks totalUnderlying liquidity separately from prAPE supply. All real value inside the system is derived from the underlying pool state.

Scaled Share Accounting

Each deposit is converted into immutable scaledAmount shares using the current liquidityIndex. These shares never change after staking.

Global Index Expansion

Rewards stored in rewardReserve increase the liquidityIndex through distributeRewards(), instantly updating the value of every position globally.

Queued Withdraw System

Withdrawals burn prAPE, reconstruct the user's current indexed value, and enter a 7-day withdraw queue before claim execution.

Protocol Integration

prAPE × Teller

Expanding the utility of ApeChains first liquid staking token through lending markets powered by Teller.

Through this integration, prAPE becomes more than a liquid staking asset. Holders can access additional opportunities within the ApeChain ecosystem while maintaining exposure to staking rewards and protocol growth.

Lending Ready

prAPE can participate in lending markets powered by Teller.

Maintain Exposure

Access liquidity while maintaining staking exposure.

DeFi Expansion

Bringing deeper capital efficiency and utility to ApeChain.

This integration marks an important milestone for PrimalFi and represents another step toward building a sustainable and composable DeFi layer on ApeChain.

Core accounting model

The protocol never stores a user balance directly. Instead, every position is reconstructed dynamically using immutable shares and a global growth index.

balance = scaledAmount × liquidityIndex / 1e18

scaledAmount

Fixed protocol shares received when staking. This value NEVER changes.

liquidityIndex

Global multiplier that represents accumulated protocol growth.

Real Balance

User balances are reconstructed dynamically from immutable shares × liquidityIndex.

How the system works

1. USER STAKES

APE enters the protocol and becomes productive liquidity.

2. SHARES CREATED

Immutable scaled shares are calculated from the current index.

3. prAPE MINTED

Users receive prAPE as liquid protocol ownership.

4. INDEX GROWS

Rewards expand liquidityIndex and increase balances globally.

Rewards do NOT mint more tokens

Rewards accumulate inside the protocol reserve.

The protocol updates ONLY one global variable:

newIndex = oldIndex × (TVL + rewards) / TVL

This increases every user balance instantly.

No rebasing. No inflation. No balance rewrites.

Why this model scales

Traditional staking systems must update balances individually.

PrimalFi only updates the global liquidityIndex.

Every account reflects the new value automatically.

Result

• Instant global reward distribution
• Gas efficient architecture
• Massive user scalability
• No manual claiming required

NFT Ecosystem Utility

NFTs asprotocol credentials

PrimalFi integrates ecosystem NFT collections through a non-custodial verification framework where NFTs function as protocol-linked fee credentials.

NFTintegration layer

Non-Custodial Design

NFTs remain fully owned by users at all times and are never locked, transferred, or deposited into the protocol.

Fee Optimization

Collections function as optional verification-based discount credentials capable of reducing staking execution fees.

Protocol Verification

Benefits are applied dynamically through ownership validation during staking execution.

Controlled Exposure

Protocol-side discount limits and configurable fee floors maintain sustainable economic parameters.

Protocol Integration Flow

NFT verification poweredfee optimization

PrimalFi integrates NFT collections through a lightweight verification layer directly connected to the staking execution flow. During stake creation, the protocol can validate ownership of an approved NFT collection and automatically apply a protocol-side fee reduction without requiring NFT deposits, escrow, wrappers, or asset custody transfers.

NFT Custody

0%

Verification

Onchain

NFT Detection

The user selects a supported NFT collection during stake execution.

Ownership Validation

The protocol verifies NFT ownership directly onchain through ERC-721 balance checks.

Dynamic Fee Reduction

If eligible, the configured discount is automatically applied to staking fees.

Normal Stake Creation

The stake is created normally while the NFT remains fully inside the user's wallet.

The future ofApeChain staking

PrimalFi is a share-based staking protocol on ApeChain. Users deposit APE and receive prAPE, a liquid staking token representing ownership of the protocol liquidity pool. Value grows automatically through liquidityIndex expansion.
