Forte Hacks by Flow 2025 | DeFi Track Submission

🚀 LIVE ON FLOW TESTNET | Built for Professional Financial Management | Ready for Global Adoption 🌍

Seflow is a comprehensive automated salary management platform that revolutionizes how professionals handle their income through intelligent DeFi compounding and streamlined financial workflows. Built on Flow blockchain, Seflow addresses critical pain points in traditional salary management by providing automated splitting, yield optimization, and seamless DeFi integration.

Our platform enables users to automatically distribute their salary across multiple categories (savings, investments, expenses) while simultaneously maximizing returns through automated LP compounding and yield farming strategies.

🎯 Key Impact: Transform manual salary management into an automated, yield-generating financial system for modern professionals.

DeFi Track - Comprehensive Financial Automation & Yield Optimization:

The global professional salary management market faces significant inefficiencies:

1. Manual Financial Management: 85% of professionals manually manage salary allocation, leading to inconsistent savings and missed investment opportunities
2. Low Yield Generation: Traditional savings accounts offer 0.1-2% APY while DeFi protocols provide 5-20% yields
3. Complex DeFi Access: 70% of professionals interested in DeFi find current platforms too complex for regular use
4. Time-Consuming Processes: Average professional spends 3-5 hours monthly on financial management tasks
5. Missed Automation Opportunities: 90% of salary allocation could be automated but remains manual

Seflow addresses these challenges through comprehensive automation:

Seflow employs a modern, three-layer architecture designed for scalability, security, and user experience:

Cadence Resource Implementation:

// Secure salary management using Flow's resource system
pub resource SalaryAllocation {
    pub let totalAmount: UFix64
    pub let allocations: {String: UFix64}
    pub let compoundingEnabled: Bool
    
    init(amount: UFix64, percentages: {String: UFix64}) {
        self.totalAmount = amount
        self.allocations = {}
        
        // Validate percentages sum to 100%
        var total: UFix64 = 0.0
        for percentage in percentages.values {
            total = total + percentage
        }
        assert(total == 100.0, message: "Percentages must sum to 100%")
        
        // Calculate allocation amounts
        for category in percentages.keys {
            self.allocations[category] = amount * (percentages[category]! / 100.0)
        }
        self.compoundingEnabled = true
    }
    
    pub fun executeAllocation(): @{String: FlowToken.Vault} {
        let vaults: @{String: FlowToken.Vault} <- {}
        
        for category in self.allocations.keys {
            let amount = self.allocations[category]!
            vaults[category] <-! FlowToken.createEmptyVault() as! @FlowToken.Vault
            // Implementation continues...
        }
        
        return <- vaults
    }
}

Resource Safety Benefits:

• Assets cannot be accidentally lost or duplicated
• Compile-time guarantee of proper resource handling
• Automatic cleanup prevents memory/asset leaks
• Type safety for all financial operations

Smart Contract Architecture:

pub contract AutoCompoundHandler {
    pub resource CompoundingStrategy {
        pub let poolAddress: Address
        pub let targetAPY: UFix64
        pub let compoundFrequency: UInt64 // seconds between compounds
        pub var lastCompounded: UFix64
        pub var totalEarned: UFix64
        
        pub fun shouldCompound(): Bool {
            let currentTime = getCurrentBlock().timestamp
            return currentTime >= self.lastCompounded + UFix64(self.compoundFrequency)
        }
        
        pub fun executeCompound() {
            pre {
                self.shouldCompound(): "Not ready for compounding"
            }
            
            // Harvest yield from LP position
            let yield = self.harvestYield()
            
            // Reinvest yield back into LP
            self.reinvestYield(amount: yield)
            
            // Update tracking
            self.lastCompounded = getCurrentBlock().timestamp
            self.totalEarned = self.totalEarned + yield
            
            emit CompoundExecuted(
                pool: self.poolAddress,
                amount: yield,
                timestamp: self.lastCompounded
            )
        }
    }
}

Automation Benefits:

• Maximizes compound interest through frequent reinvestment
• Eliminates manual intervention and timing risks
• Optimizes gas costs through batch operations
• Provides transparent tracking and reporting

Yield Strategy Engine:

pub contract YieldOptimizer {
    pub struct PoolMetrics {
        pub let address: Address
        pub let currentAPY: UFix64
        pub let tvl: UFix64
        pub let riskScore: UInt8
        pub let impermanentLossRisk: UFix64
    }
    
    pub fun findOptimalPool(amount: UFix64, riskTolerance: UInt8): Address {
        let availablePools = self.getActivePools()
        var bestPool: Address = availablePools[0].address
        var bestScore: UFix64 = 0.0
        
        for pool in availablePools {
            // Calculate risk-adjusted yield score
            let riskAdjustedAPY = pool.currentAPY * (1.0 - pool.impermanentLossRisk)
            let capacityFactor = self.calculateCapacityFactor(pool: pool, amount: amount)
            let riskMatch = pool.riskScore <= riskTolerance ? 1.0 : 0.5
            
            let score = riskAdjustedAPY * capacityFactor * riskMatch
            
            if score > bestScore {
                bestScore = score
                bestPool = pool.address
            }
        }
        
        return bestPool
    }
}
