Create veLITH Safe Batch Generator

Generate Safe Transaction Builder compatible JSON for creating and distributing veLITH (veNFTs) to multiple recipients by locking LITHOS tokens.

Prerequisites

• The .env file must contain RPC_URL for Plasma mainnet
• The multisig must hold sufficient LITHOS tokens for the distribution
• User must provide recipient addresses and amounts

Contract Addresses (Plasma Mainnet)

• LITHOS Token: 0xAbB48792A3161E81B47cA084c0b7A22a50324A44
• VotingEscrow: 0x2Eff716Caa7F9EB441861340998B0952AF056686
• Chain ID: 9745

Lock Duration Reference

Duration	Seconds
2 years (max)	63,072,000
1 year	31,536,000
6 months	15,768,000
3 months	7,884,000
1 month	2,628,000
1 week	604,800

Note: VotingEscrow rounds lock end time DOWN to the nearest week.

Instructions

Step 1: Parse recipient list

Accept input in format (whitespace or comma separated):

<address>    <amount>
<address>    <amount>
...

Amounts are in whole LITHOS tokens (not wei).

Step 2: Verify multisig has sufficient LITHOS

source .env && cast call 0xAbB48792A3161E81B47cA084c0b7A22a50324A44 "balanceOf(address)(uint256)" <MULTISIG_ADDRESS> --rpc-url $RPC_URL

Convert the result from wei to tokens (divide by 10^18) and compare to total required.

Step 3: Generate approve calldata

The multisig must approve VotingEscrow to spend LITHOS tokens.

# Total amount in wei = sum of all amounts * 10^18
cast calldata "approve(address,uint256)" 0x2Eff716Caa7F9EB441861340998B0952AF056686 <TOTAL_AMOUNT_WEI>

The function selector for approve(address,uint256) is 0x095ea7b3.

Step 4: Generate create_lock_for calldata for each recipient

# For each recipient:
# _value = amount in wei (amount * 10^18)
# _lock_duration = duration in seconds (e.g., 63072000 for 2 years)
# _to = recipient address
cast calldata "create_lock_for(uint256,uint256,address)" <VALUE_WEI> <DURATION_SECONDS> <RECIPIENT_ADDRESS>

The function selector for create_lock_for(uint256,uint256,address) is 0xd4e54c3b.

Step 5: Create Safe batch JSON

Generate a JSON file with this structure:

{
  "version": "1.0",
  "chainId": "9745",
  "createdAt": <UNIX_TIMESTAMP>,
  "meta": {
    "name": "Distribute veLITH to <NUM_RECIPIENTS> recipients",
    "description": "Lock <TOTAL_AMOUNT> LITHOS tokens for <DURATION> and distribute veNFTs to <NUM_RECIPIENTS> addresses.",
    "txBuilderVersion": "1.16.5"
  },
  "transactions": [
    {
      "to": "0xAbB48792A3161E81B47cA084c0b7A22a50324A44",
      "value": "0",
      "data": "<APPROVE_CALLDATA>",
      "contractMethod": {
        "inputs": [
          {
            "internalType": "address",
            "name": "spender",
            "type": "address"
          },
          {
            "internalType": "uint256",
            "name": "amount",
            "type": "uint256"
          }
        ],
        "name": "approve",
        "payable": false
      },
      "contractInputsValues": {
        "spender": "0x2Eff716Caa7F9EB441861340998B0952AF056686",
        "amount": "<TOTAL_AMOUNT_WEI>"
      }
    },
    {
      "to": "0x2Eff716Caa7F9EB441861340998B0952AF056686",
      "value": "0",
      "data": "<CREATE_LOCK_FOR_CALLDATA>",
      "contractMethod": {
        "inputs": [
          {
            "internalType": "uint256",
            "name": "_value",
            "type": "uint256"
          },
          {
            "internalType": "uint256",
            "name": "_lock_duration",
            "type": "uint256"
          },
          {
            "internalType": "address",
            "name": "_to",
            "type": "address"
          }
        ],
        "name": "create_lock_for",
        "payable": false
      },
      "contractInputsValues": {
        "_value": "<AMOUNT_WEI>",
        "_lock_duration": "<DURATION_SECONDS>",
        "_to": "<RECIPIENT_ADDRESS>"
      }
    }
    // ... repeat for each recipient
  ]
}

Step 6: Write to file

Save the JSON to safe-txs/safe.distribute-velith-<TIMESTAMP>.json.

Verification

After the transaction is executed, verify the veNFTs were created:

# Check recipient received a veNFT
source .env && cast call 0x2Eff716Caa7F9EB441861340998B0952AF056686 "balanceOf(address)(uint256)" <RECIPIENT> --rpc-url $RPC_URL

# Get the token ID
source .env && cast call 0x2Eff716Caa7F9EB441861340998B0952AF056686 "tokenOfOwnerByIndex(address,uint256)(uint256)" <RECIPIENT> 0 --rpc-url $RPC_URL

# Check voting power
source .env && cast call 0x2Eff716Caa7F9EB441861340998B0952AF056686 "balanceOfNFT(uint256)(uint256)" <TOKEN_ID> --rpc-url $RPC_URL

# Check lock details
source .env && cast call 0x2Eff716Caa7F9EB441861340998B0952AF056686 "locked(uint256)((int128,uint256))" <TOKEN_ID> --rpc-url $RPC_URL

Example Usage

User: "Create veLITH for these addresses with 2-year locks: 0x1234...abcd 100000 0x5678...efgh 50000 0x9abc...ijkl 25000"

Workflow:

1. Parse: 3 recipients, total 175,000 LITHOS
2. Query multisig balance: 200,000 LITHOS (sufficient)
3. Calculate wei amounts:
   • Total: 175000 * 10^18 = 175000000000000000000000
   • Each recipient's amount * 10^18
4. Generate approve calldata for 175000000000000000000000 wei
5. Generate 3 create_lock_for calldatas (63072000 seconds for 2 years)
6. Create batch JSON with 4 transactions (1 approve + 3 creates)
7. Save to safe-txs/safe.distribute-velith-1705000000.json

Common Mistakes to Avoid

1. Forgetting to convert to wei - All amounts must be multiplied by 10^18.

2. Insufficient approval - The approve amount must be >= total of all create_lock_for amounts.

3. Wrong lock duration units - Duration is in SECONDS, not days or weeks.

4. Exceeding max lock - Maximum lock duration is 2 years (63,072,000 seconds). VotingEscrow will revert if exceeded.

5. Zero amounts - VotingEscrow reverts on zero-value locks.

6. Duplicate recipients - Each recipient will get a SEPARATE veNFT. If you want to add to an existing lock, use deposit_for() instead.

Notes

• Each create_lock_for() call creates a NEW veNFT for the recipient
• The recipient immediately owns the veNFT and can vote, transfer, or manage it
• Voting power decays linearly over the lock period
• Recipients can extend their lock duration or add more tokens after receiving
• The multisig pays the LITHOS tokens; recipients receive veNFTs at no cost
