Lock Proof

How it works#

1. 1

   The holder picks how many tokens to lock, an unlock date, and who can cancel or change the recipient. Those rights are shown in plain words before signing.

2. 2

   Our server builds the Jupiter Lock transaction and the wallet signs it. The server then checks it, adds the second signature and sends it.

3. 3

   The lock appears on the token's Lock Proof list with a live countdown and a link to its account on an explorer.

What a lock shows#

• The amount locked and its share of supply.
• The unlock date or the vesting schedule, with a live countdown.
• Who can cancel the lock and who can change its recipient, in plain words.
• Where it was made (Jupiter Lock or Streamflow) and a link to its account.

What it costs#

0.02 SOL per lock. It is paid inside the lock transaction. Viewing locks is free.

Good to know#

• Cancel and recipient change rights are set when the lock is created. A lock nobody can cancel stays locked until its date. A lock the creator can cancel shows that right on the list.
• Jupiter Lock is a separate program run by Jupiter. It was audited by OtterSec and Sec3 and supports Token-2022. Jupiter can upgrade the program.
• A lock can run from one day to ten years.
• Locks made with Jupiter Lock or Streamflow show on the list when we can detect them. A lock made some other way may not.
• A lock shows that tokens in that account cannot be sold before the date. It does not show that the team will not sell other tokens.
• Lock Proof never says a token is safe.

Under the hood#

• Creating a lock uses Jupiter Lock's create vesting escrow v2 instruction, with the recipient, the schedule and the cancel and update modes you chose.
• Our fee is a System Program transfer of 0.02 SOL to our treasury in the same transaction.
• To list locks we read lock accounts owned by the Jupiter Lock and Streamflow programs and show each schedule.
• The wallet that locks signs it. A one time key that only picks the lock's address adds the second signature on our server. That key holds nothing and has no rights over the lock.
