+# Summary
+
+This proposal suggests extending the standard Jetton Wallet by adding the option `get_locked_balance` get method.
+
+# Motivation
+
+New contracts have may want to disable jetton transfer until a time in the future. For this case, the Jetton Wallet should show zero balance to not affect old services and add a new get method to allow to get a locked balance and expiration date.
+
+The standard may use for:
+1. Jetton DAO contract may want to disable jetton transfer until voting is in progress.
+2. Jetton Vesting contract may want to release tokens in the future.
+
+
+# Guide
+
+Upon calling `get_locked_balance` get method Jetton Wallet should respond with integer jetton balance, integer jetton locked balance, and expiration date in integer UNIX epoch seconds format.
+
+# Specification
+
+## New Jetton Master contracts
+An example of the implementation jetton wallet code can be found [here](https://github.com/OpenProduct/jetton-dao-contracts/blob/ece785f82e07a7833194992cfc0e2fa1a690b524/contracts/jetton_wallet.func#L367)
+
+
+Jetton Wallet should implement the get method:
+
+```
+(int, int, int) get_locked_balance() method_id {
+  (int balance, slice owner_address,
+          slice jetton_master_address, cell jetton_wallet_code,
+          int locked, int lock_expiration,
+          cell vote_keeper_code) = load_data();
+  return (balance, locked, lock_expiration);
+}
+```
+
+# Drawbacks
+
+The standard implies single expiration date single locked balance.
+
+# Rationale and alternatives
+
+This design allows us to show balance and locked balance in a user-friendly and clear format in blockchain explorers and wallets.
+
+# Prior art
+

+
+# Unresolved questions
