Problem Statement

RIF Staking Platform - Detailed DescriptionWhat is RIF Staking Platform?RIF Staking Platform is a revolutionary DeFi application that solves the fundamental problem of DeFi fragmentation by combining token swapping and staking into a single, seamless transaction. Instead of users having to navigate multiple platforms, sign multiple transactions, and pay multiple gas fees, our platform enables one-click multi-token staking with intelligent batch transaction processing.The Core Problem We SolveCurrent DeFi User Journey (Broken):User wants to stake RIF tokensUser has rUSDT, rBTC, rUSDC insteadUser goes to Uniswap/SushiSwap → Swaps rUSDT to RIF (Transaction 1)User approves RIF spending → Approval transaction (Transaction 2)User goes to staking platform → Stakes RIF (Transaction 3)User repeats for each token → 3+ transactions per tokenTotal: 6-9 transactions, multiple gas fees, 10+ minutesOur Solution (Fixed):User selects multiple tokens (rUSDT, rBTC, rUSDC)User clicks "Swap & Stake" → One transactionDone! → All tokens swapped to RIF and staked automaticallyTechnical ArchitectureSmart Contract Layer:RIFBatchDepositer Contract: Handles the entire flow atomicallyToken Transfer: Pulls selected tokens from user's walletDEX Integration: Swaps tokens to RIF using existing DEX infrastructureAutomatic Staking: Deposits RIF into the official staking contractAtomic Safety: All operations succeed or fail togetherFrontend Layer:React + TypeScript: Modern, type-safe developmentWagmi + RainbowKit: Seamless wallet integrationReal-time Balance Display: Live token balances with copy-to-clipboardSmart Approval Detection: Only requests approvals when neededTransaction Status Tracking: Real-time updates and explorer linksInnovation Layer:EIP-5792 Implementation: Batch multiple operations in one signatureSmart Allowance Checking: Eliminates unnecessary approval popupsMulti-token Support: Handle any ERC-20 token combinationGas Optimization: Up to 50% reduction in transaction costsKey Features & Innovations1.

Solution

How it's madeArchitecture & ImplementationThe project started with the goal of implementingEIP-5792 batch transactionsto combine multiple operations into a single signature. However, we discovered that Rootstock doesn't support EIP-5792 yet, so we built adual-chain approach:Base Sepolia: Full EIP-5792 implementation withwallet_sendCallsfor atomic batch transactionsRootstock Testnet: Traditional separate transactions with smart allowance checkingKey Technical DecisionsSmart Allowance Detection:Instead of always requesting approvals, we query existing allowances first and only request approvals when insufficient. This eliminates unnecessary popups and saves gas.Atomic Transaction Design:The main contract functionexecuteCallsAndDeposithandles the entire flow atomically - token transfers, DEX swaps, and staking all succeed or fail together.Dual-Chain Strategy:We implemented both EIP-5792 (Base Sepolia) and traditional (Rootstock) flows to demonstrate the evolution of DeFi transaction patterns while maintaining compatibility.Notable Implementation DetailsBatch Transaction Logic:For EIP-5792, we encode multiple function calls (approvals + main contract call) into a singlesendCallsrequest, while for traditional flow, we execute approvals sequentially followed by the main transaction.Smart Error Handling:Graceful handling of user rejections, insufficient funds, and network errors with user-friendly messages.The project showcases the future of DeFi UX through EIP-5792 while maintaining backward compatibility with traditional transaction patterns.
