Handle "Sequence Number Mismatch" errors

[soomtochukwu]

Description

The implementation of 'Handle "Sequence Number Mismatch" errors' is a critical bridge between our application layer and the Soroban smart contract environment.
This task involves the precise construction and management of on-chain transactions, ensuring data integrity across the decentralized ledger.
By providing a robust interaction layer, we enable complex logic like escrow deposits, milestone releases, and dispute resolutions to function trustlessly.
Security is the highest priority here, as any error in XDR construction or transaction submission could lead to failed operations or lost funds.
This module is essential for making the platform truly decentralized and leveraging the full power of the Stellar ecosystem.

Requirements

1. Utilize the latest version of the Stellar SDK for JavaScript/TypeScript to ensure compatibility with Soroban features.
2. Implement comprehensive XDR building logic that handles all contract arguments, including custom types and address conversions.
3. The system must include a robust transaction simulation step to estimate fees and predict success before asking the user to sign.
4. Handle asynchronous RPC polling to monitor transaction status across multiple ledgers until confirmation or final failure.
5. Ensure all cryptographic signatures are handled securely through the connected wallet provider without exposing private data.

Acceptance Criteria

1. Transactions must be successfully built, simulated, and submitted to the Testnet RPC with clear status feedback to the user.
2. The implementation must correctly handle 'Sequence Number Mismatch' errors by refreshing the source account state and retrying.
3. Detailed logs of the raw XDR and simulation results must be available in dev environments for debugging and auditing purposes.
4. Fees and resource limits (CPU, memory) must be dynamically adjusted based on the latest simulation results to minimize failures.
5. Successful confirmation must trigger immediate UI updates to reflect the new on-chain state (e.g., balance changes or status updates).

UI Design Prompt

'Design a highly technical yet accessible interface for Handle "Sequence Number Mismatch" errors that provides transparency into the blockchain layer.
Use a clean, monospace typography for raw XDR or transaction hashes to give a professional, developer-friendly look.
The UI should feature a progress tracker for the multi-step transaction lifecycle: Build -> Simulate -> Sign -> Submit -> Confirm.
Include subtle animations (like a pulsing ring or progress bar) to indicate the app is waiting for the decentralized network.
Ensure high-contrast success and error messages that include direct links to external block explorers for verification.'
