SquiStack is a Telegram-native savings and yield platform purpose-built for the African retail saver. By abstracting the complexity of on-chain infrastructure, SquiStack enables any user with a Telegram account and a Nigerian bank account to access dollar-denominated yield ranging from 20% to 200% APY — across four distinct savings products deployed on Base L2. No wallet configuration required. No foreign account. No prior knowledge of blockchain technology.

Problem & Market Opportunity

Naira lost vs USD in 2023–24

Nigeria has a savings problem — but not the one typically associated with developing markets. Nigerians are prolific, disciplined savers. The cultural prevalence of ajo circles, esusu clubs, and structured savings applications attests to a population that deeply values financial discipline. The problem is not the will to save. The problem is that every mainstream savings instrument available to the retail Nigerian saver systematically destroys purchasing power.

Nigerian commercial banks pay 3–9% per annum on naira-denominated savings accounts. Against an inflation rate that has ranged from 25–35% in recent years, the real return on a naira savings deposit is deeply negative. Every year a naira sits in a bank account, its purchasing power erodes. This is not a marginal difference — it represents a structural wealth transfer away from those least able to absorb it.

The alternative — on-chain stablecoin yield protocols generating 20–100%+ APY on USDC — exists and is accessible today. However, the onboarding pathway requires crypto wallet management, gas fee literacy, cross-chain bridge transactions, and a level of technical competency that excludes the overwhelming majority of potential beneficiaries. That gap — between the instrument that exists and the population that could benefit from it — is SquiStack's founding thesis.

Three structural failures SquiStack addresses

Currency erosion

Naira depreciation has outpaced every mainstream savings vehicle available to the Nigerian retail market. Dollar-pegged stablecoins represent the natural structural hedge — but accessing them at scale has historically required technical expertise that the target population does not possess.

Informal savings risk

An estimated $3T+ circulates annually through informal African savings collectives. These groups — ajo, esusu, akawo — operate without transparency, contractual enforcement, or recourse mechanisms. Billions are lost each year to organiser defaults, disputes, and fraud. The mechanism is sound; the infrastructure is not.

The yield access gap

Global DeFi protocols currently offer 20–100%+ APY on dollar-denominated stablecoin positions. Nigerian commercial banks offer 3–9% on naira. For equivalent capital committed over a three-to-five year period, the difference in outcome compounds into a material wealth gap. Closing this gap requires removing the access barrier entirely.

02

The SquiStack Solution

SquiStack constructs a seamless, end-to-end bridge between Nigerian naira and on-chain dollar yield — operated entirely within Telegram. The user journey is deliberately frictionless: deposit NGN via standard bank transfer, select a savings product, earn yield denominated in USD, and withdraw NGN directly to a verified bank account. No wallet to configure. No gas fees to manage. No protocol knowledge required.

The underlying architecture — smart contracts on Base L2, multi-protocol yield routing, embedded wallet infrastructure, and automated FX settlement — operates silently in the background. To the end user, SquiStack presents as a well-designed savings application. That deliberate simplicity is the product.

🎯 The distribution insight

Telegram is already installed on the devices of hundreds of millions of users across Africa. It requires no additional app store permissions, no unfamiliar interface, and no new account creation. SquiStack meets savers within the communication platform they already use daily — eliminating the distribution problem that has historically constrained fintech adoption in emerging markets.

Users authenticate through Telegram's native authorisation flow. A non-custodial embedded wallet is provisioned silently via Privy's infrastructure. The user initiates a bank transfer, selects a product, and the platform handles all subsequent operations: FX conversion, on-chain deployment, yield accrual, periodic distribution, and eventual withdrawal settlement back to naira.

Product Suite

SquiStack launches with four savings products, each designed for a distinct saver profile and risk appetite — from the first-time saver seeking a flexible recurring plan, to the committed capital holder seeking maximum fixed-term yield, to the crypto-native investor seeking unit accumulation on existing holdings.

🔄
AutoSave
Flexible recurring savings — weekly at 20% APY or monthly at 25% APY. Contribute any amount. No lock period. Full balance withdrawable at any time.
20–25% APY

AutoSave is SquiStack's most accessible savings product. Users configure a contribution amount and cadence — weekly or monthly — and the platform handles deployment automatically on each scheduled date. The yield rate reflects the commitment frequency: weekly contributors earn 20% APY, while monthly contributors earn 25% APY, compensating for the longer interval between capital deployments.

There is no lock period. Users may terminate their AutoSave plan and withdraw their full balance — principal plus all accrued yield to the most recent distribution — at any time, without penalty. This product architecture is designed to serve as the primary entry point for first-time savers: a zero-friction, high-accessibility introduction to dollar-denominated yield.

Target segment: First-time savers, salaried employees seeking an automated standing-order equivalent, and any user seeking dollar exposure with no minimum commitment and no technical overhead.

Principal only

SafeLock is the DeFi equivalent of a fixed-term deposit — a product structure that is deeply familiar to the Nigerian retail saver. The mechanics are identical to what Nigerian banks offer: commit a lump sum for a defined period and collect principal plus yield at maturity. The fundamental difference is the return profile. Nigerian fixed deposits pay 12–15% per annum in naira. SafeLock delivers 55% to 200% APY in dollar terms, calibrated directly to the length of the user's commitment.

The APY schedule is structured as follows: 6 months at 55%, 8 months at 100%, 12 months at 130%, and 18 months at 200%. The rate is fixed at the time of vault creation and does not fluctuate for the duration of the lock. This predictability is a deliberate design choice — users committing to longer terms should have certainty over their expected return.

The lock is enforced on-chain by smart contract. No administrative override is possible, including by SquiStack's own operations team. Users who submit an early exit request receive their full principal in its entirety, with zero yield — preserving capital while enforcing the yield-commitment relationship that makes the elevated rates viable.

Target segment: Capital holders with a defined savings horizon. Suitable for bonus deployment, property purchase staging, emergency reserve building, or any goal with a known future date and a meaningful deposit amount.

CryptoFlex

CryptoFlex
Yield paid in the asset you deposit. Unit accumulation.

Early exit
Principal only

CryptoFlex is designed for a fundamentally different investment objective: unit accumulation rather than dollar return maximisation. Users who hold conviction assets — Bitcoin, Ethereum, Solana — and intend to maintain those positions regardless of short-term price movements are leaving yield on the table by holding in a static wallet. CryptoFlex deploys those assets into yield-bearing strategies and pays the return in the same native asset. A user who deposits 1.00 BTC receives 1.10 BTC at maturity on a 10% APY contract — irrespective of any price movement in the interim.

APY varies by asset, driven by prevailing on-chain yield opportunities specific to each asset class: liquid staking derivative rates for ETH (via cbETH and stETH protocols), wrapped BTC lending market rates, and native staking reward rates for proof-of-stake assets. All rates are displayed in-app in real time, based on trailing 30-day protocol performance. Current indicative ranges are 8–15% APY in BTC terms, 10–20% for ETH, and 20–40% for higher-volatility L1 and L2 assets.

Like SafeLock, CryptoFlex operates on a fixed-term contract established at the point of deposit. Early exit returns the deposited asset in full, with no yield distribution.

Target segment: Crypto-native investors and long-term holders with strong directional conviction on specific assets. Particularly compelling for BTC and ETH holders who seek to compound their unit count during periods of extended holding.

₦50k/month
Duration
12 months

JointVault is SquiStack's most culturally resonant product, and arguably its most ambitious. Ajo, esusu, and akawo — Nigeria's informal rotating savings collectives — have been the primary savings infrastructure for the majority of Nigerians for generations. They function because a single powerful mechanism — social commitment — enforces financial discipline more effectively than any bank product. JointVault preserves that mechanism and eliminates its critical weakness: dependence on a trusted human organiser.

The product structure replaces the organiser with a smart contract. Users join the vault in units called nodes, each representing a commitment of ₦50,000 per month. Users may hold multiple nodes simultaneously to scale their position. Every month for 12 months, each node contribution is due. All contributions are pooled, deployed into yield-generating strategies on Base L2, and earn 60% APY for the duration of the contract. At the 12-month maturity date, principal plus accrued yield is distributed to each member in proportion to their node count and contribution record.

Default handling

If a user misses a monthly payment on any node, that specific node is frozen from the missed payment date. No further yield accrues on the frozen node, though previously earned yield is preserved. At maturity, the user receives the total principal contributed on that node with zero yield. All other nodes held by the same user, and all other members of the vault, are entirely unaffected. The vault continues to operate on schedule.

There is no mechanism to exit JointVault early. The 12-month commitment is enforced on-chain without exception. This structural rigidity is by design — it is precisely what differentiates JointVault from a standard savings product and what makes it a genuine commitment mechanism rather than a discretionary one.

Target segment: Goal-oriented savers, workplace savings groups, family savings circles, and any individual who benefits from externally enforced financial commitment. JointVault is particularly well suited to users who have historically struggled to maintain informal ajo commitments due to organiser reliability concerns.

Yield Stack & Architecture

All SquiStack products are deployed on Base L2 — Coinbase's Ethereum Layer 2 network, selected for its EVM compatibility, sub-cent transaction costs, institutional-grade security model, and a rapidly maturing DeFi ecosystem. User capital flows through a layered yield stack, with strategy allocation determined dynamically based on prevailing protocol rates, liquidity depth, and risk parameters established in the vault strategy contracts.

Aave v3 on BasePrimary money market · USDC/ETH supply yield
Aerodrome FinanceNative Base AMM · LP rewards in USDC pairs
Morpho OptimizerPeer-matched lending · 15–25% rate uplift on Aave
cbETH / stETH stakingLiquid staking derivatives · ETH yield for CryptoFlex
Compound v3Secondary fallback · rate optimisation layer

Wallet infrastructure is provided by Privy's embedded wallet SDK. Each user receives a provisioned non-custodial wallet on Base L2 at first authentication, without any action required on their part. Account abstraction enables full gas sponsorship — users are never exposed to network transaction costs. All smart contracts are open source, deployed behind 48-hour timelocks, and administered through a 3-of-5 multisig governance structure. Audit reports are published publicly prior to mainnet deployment of any new contract.

05

Revenue & Tokenomics

SquiStack's revenue model is structurally aligned with user outcomes. The platform charges a 15% performance fee on yield generated. Revenue is earned exclusively when users earn — creating a direct incentive to maximise strategy performance rather than extract from deposits. There are no management fees, no subscription charges, and no undisclosed spreads beyond a transparent 0.5% FX conversion cost applied to NGN ↔ USDC exchanges. Deposits are fee-free. On-chain gas costs are abstracted and sponsored entirely by the platform.

All APY figures communicated to users reflect post-performance-fee net yield. Users receive the stated rate. SquiStack's fee is deducted from gross protocol yield before any distribution is made to vault balances.

Governance token

A governance and utility token is planned for a subsequent phase of platform development. Proposed token utility includes yield multipliers on vault deposits, fee reduction tiers, on-chain governance participation rights, and structured referral reward distributions. Detailed token parameters — total supply, allocation tranches, vesting schedules, and the generation event timeline — will be published in a dedicated token disclosure document ahead of any offering. No token is being sold, offered, or implied by this litepaper.

Team & Backers

SquiStack is built by a team with direct operational experience across African fintech, DeFi protocol design, and consumer product growth at scale. The founding team has previously shipped financial products used by hundreds of thousands of users across Nigeria — spanning payments infrastructure, digital lending, and cross-border remittances.

This institutional knowledge of the Nigerian financial consumer is foundational to the product. The team understands the acute distrust of formal financial institutions, the embedded preference for messaging-native interfaces, the cultural weight of savings commitments in West African communities, and the deep sensitivity to FX risk among a population that has lived through multiple significant devaluations. SquiStack is not a product designed externally and adapted for Africa. It is conceived, designed, and built by Africans for Africans — from first principles.

Our angel investor base includes senior operators from Flutterwave, Paystack, and leading African venture capital firms. Details of our seed financing round will be disclosed at public launch.

Risk Factors

⚠️ Material risk disclosure

Participation in DeFi yield products carries material and potentially total risk of capital loss. Do not commit funds that cannot be lost in full. SquiStack is not a licensed bank or deposit-taking institution. User funds are not insured by the NDIC or any government guarantee scheme. This document does not constitute financial, investment, or legal advice.

Smart contract risk

Vault strategies are executed via audited Solidity smart contracts deployed on Base L2. Notwithstanding professional security review, undiscovered vulnerabilities may exist. A successful exploit of any vault or strategy contract could result in partial or total loss of deposited principal.

Protocol dependency risk

SquiStack's yield generation relies on third-party DeFi protocols including Aave v3, Aerodrome Finance, and Morpho. A critical failure, governance attack, or liquidity crisis at any dependency layer could materially impair yield generation or, in severe scenarios, principal security.

Yield variability risk

All stated APY figures reflect current rate settings and trailing protocol performance. On-chain lending and liquidity provision rates are variable and respond continuously to market supply-demand dynamics. Yields may decline significantly during periods of low market activity, liquidity withdrawal, or systemic DeFi stress events.

Foreign exchange risk

NGN deposits are converted to USDC at the point of vault entry. If the naira appreciates materially against the US dollar between the deposit date and the withdrawal date, the NGN-denominated payout may be lower than the original deposit in nominal terms — even where the dollar-denominated balance reflects a positive return. This scenario has been historically infrequent but cannot be excluded.

Regulatory risk

The regulatory framework governing crypto assets and digital financial services in Nigeria and across Sub-Saharan Africa remains in active development. Adverse legislative or regulatory changes may necessitate product modifications, jurisdictional restrictions, or temporary service interruptions.
