A primer on stack-based deposits, compounding yield, prize pools, and referral rewards.
StackerFund is a DeFi protocol that creates a series of stacks — fixed-size deposit pools that fill sequentially. When you deposit into a stack, you earn yield from all future stack deposits, creating a compounding reward mechanism that incentivizes early participation.
💡 Key Insight: Every deposit that comes after yours generates yield for you. The earlier your stack, the more future stacks feed into your reward.
Deposit USDC into the current stack. Each stack grows 50% larger than the last.
As new deposits fill future stacks, your share generates claimable yield.
Claim your accrued yield at any time. Each new deposit increases your available reward.
The last depositor before the countdown expires wins 50% of the prize pool.
The protocol operates in sequential stacks. Each stack has a fixed size that starts at 10 USDC and grows by 50% with each subsequent stack:
When a stack fills up, a new one is automatically created. Deposits that exceed the current stack's remaining capacity can use Multi Fill to spread across multiple stacks.
Every deposit is split into fees and net deposit according to the following formula:
When the protocol has filled 2+ stacks, the excess fee (which initially adds to treasury and prize pool) converges to zero, and contributors retain a larger share.
📊 Maximum Yield: Each deposited token can earn up to 150% in total yield from future stack deposits.
All net deposits (80% of each deposit) remain held directly in the StackerFund smart contract as USDC. Funds are never sent to external lending protocols or third-party contracts. They stay in the protocol until claimed by eligible depositors via the yield mechanism.
🔒 No external risk: Your deposits are not lent out, rehypothecated, or exposed to third-party protocol risk. USDC stays in the contract until you claim it.
The prize pool is funded by 5% of every deposit. The last person to make a deposit becomes the current winner. After the prize claim wait time (default: 1 week) expires without a new deposit, anyone may trigger the prize claim:
If someone deposits after the timer has expired, the prize is automatically claimed for the previous winner before the new deposit is processed. This ensures prizes are always distributed.
Protocol revenue flows into the Treasury contract, which can deposit USDC into WISE Lending's World Mobile RWA vault on Arbitrum. This vault offers a 20% fixed APR backed by real-world assets (World Mobile telecommunications nodes).
Every user must provide a referrer address on their first deposit. The referrer earns 10% of every deposit made by the user they referred. Referral relationships are permanent — once set, they cannot be changed.
