Complete End-to-End Asset Locking Flow with Freighter Wallet

[prodbycorne]

Description

Wire up the deposit modal to actually lock assets in the Soroban pool contract using Freighter for transaction signing.

Requirements

• Build transaction in /src/app/farm/page.tsx handleLockClick() function
• Use Soroban RPC simulateTransaction before submission for fee estimation
• Call pool contract lock_assets function with user-specified amount
• Request Freighter signature via @stellar/freighter-api
• Submit signed transaction to Soroban RPC
• Show transaction status (pending → success → confirmed)
• Display transaction hash with Stellar Expert link
• Handle errors: insufficient balance, rejected signature, network failures
• Update UI after successful deposit without requiring page refresh
• Add input validation (non-zero amounts, max balance checks)

Acceptance Criteria

• ✅ User can input amount and click "Lock"
• ✅ Freighter popup appears for signature
• ✅ Transaction submits successfully to testnet
• ✅ Success/failure messages are shown
• ✅ User's position updates immediately after confirmation
• ✅ All edge cases have proper error messages

Estimated Effort: 8-12 hours
Priority: Critical
Labels: frontend, soroban, wallet-integration, typescript

Gm, I will implement the deposit flow in handleLockClick() by validating the user-entered amount, building and simulating the Soroban lock_assets transaction for fee estimation, requesting a signature through Freighter, submitting the signed transaction to the Soroban RPC, and tracking its status from pending to confirmed. I will add error handling for invalid amounts, insufficient balances, rejected signatures, and network/RPC failures. After a successful deposit, I will display the transaction hash with a Stellar Expert link and refresh the relevant balances and pool state automatically so the UI updates without requiring a page refresh. let me work on this issue please
