📝 Walkthrough

Walkthrough

Adds a new positions tracking and display feature to the frontend, including a dedicated positions page, a React hook for localStorage-persisted position management with yield calculations, and enhanced deposit flow with market expiry awareness. Also updates deployment configuration with actual program IDs and adds a build script for environment setup.

Changes

Cohort / File(s)	Summary
New Positions Page & Navigation app/positions/page.tsx, components/header.tsx	Introduces new /positions page route with header styling and adds "Positions" navigation link in header alongside "Markets".
Position Management Hook hooks/use-positions.ts	Implements new usePositions hook with localStorage-persisted position data, continuous APY yield calculations (0.12 mock rate), position creation via addPosition, and wallet-aware state management. Exports UserPosition interface with metadata fields.
Position Listing Component components/positions-list.tsx	Creates new PositionsList component displaying positions summary (total protected value, accrued yield, active count), empty state redirect, per-position details (market question, principal, yield duration), expiry status, and claim payout button for expired positions.
Deposit Modal & Market Card Updates components/deposit-modal.tsx, components/market-card.tsx	Adds marketExpiry prop to DepositModal, introduces "No-Loss" concept with shields/badges, updates success state messaging ("Position Secured!"), enhances outcome breakdown with principal protection details, and passes expiry to position creation. Market card updated to show "Stake on Yes/No" button with No-Loss badge and pass market.endDate as marketExpiry.
Solana Configuration & Program ID Updates Anchor.toml, lib/solana/constants.ts, programs/polyield_vault/src/lib.rs, programs/polyield_vault/Cargo.toml	Replaces placeholder program ID "111...111" with deployed devnet address "FWGiD7WhXu8k7eDtEwr3ZbXbvqwL7kdJgNfugrSVJ7F3" across config and Rust program declaration. Adds [toolchain] section with anchor_version = "0.30.1" to Anchor.toml. Minor formatting adjustment in Cargo.toml dependency.
Deposit Transaction Logic lib/solana/deposit.ts	Temporarily replaces on-chain Anchor deposit instruction with direct USDC transfer to vault ATA, including ATA creation logic. Original Anchor instruction path commented out for future deployment.
Build Script & Artifacts build.sh, target/.rustc_info.json, target/deploy/polyield_vault-keypair.json	Adds build script for Rust/Anchor environment setup (PATH augmentation, version printing, anchor build invocation). Includes generated rustc metadata and keypair file artifacts.

Poem

🐰 Positions now tracked with shield so bright,
LocalStorage keeps yields in sight,
From market to stake to claim at last,
No-Loss protection holds steadfast!
A positions page to view them all—
Hop along, your yields won't fall! 🛡️✨
