Closes #831
Summary
Adds a "Batch Transfer" modal to the portfolio holding action menu, allowing holders to send keys to up to 10 recipients in a single signed transaction — replacing the need to repeat the single-recipient transfer flow for team distributions and community rewards.
Changes
Holding row action menu: Added a "Batch Transfer" option alongside the existing single Transfer action.
New BatchTransferModal component:
Dynamic list of recipient rows, each with a wallet address input and a quantity input.
"Add Recipient" button appends a new row; disabled once 10 rows are present.
Each row can be removed individually (minimum 1 row).
Running "Total keys to transfer" count displayed at the top/bottom of the modal, recalculated live as quantities change.
Row-level validation:
Invalid/malformed wallet address → inline error on that row, submit disabled.
Non-numeric, zero, or negative quantity → inline error on that row.
Aggregate validation:
Total quantity across all rows compared against the holder's liquid balance; if it exceeds available balance, shows an error near the total and disables submit.
Submit is only enabled when all rows are valid, quantities are positive integers, and the total is within the liquid balance.
On submit, calls the batch_transfer contract function with the compiled recipient/quantity arrays as a single transaction.
Loading/error/success states: Modal shows a pending state while the transaction is being signed/submitted, and success/error feedback after confirmation, consistent with the existing single-transfer modal's UX.
Testing
Unit tests for row add/remove behavior, including the 10-row cap disabling "Add Recipient".
Unit tests for real-time total calculation as quantities change across rows.
Unit tests for validation: invalid address per row, invalid/zero quantity per row, total exceeding liquid balance (submit disabled in all cases).
Integration test simulating a full valid submission calling batch_transfer with the correct arguments.
Manual testnet verification: submitted a batch transfer to multiple wallets and confirmed all recipients received the correct quantities in one transaction.
Notes for reviewers
Row limit is hardcoded at 10 per the spec — happy to make this configurable if there's a reason to expect it to change.
Liquid balance check is done client-side against the holder's known balance before submit; the contract call itself will still be the final source of truth if balance changes between validation and submission (e.g. concurrent transfer in another tab) — flagging in case an additional on-chain pre-check or better error surfacing is wanted there.
