Move a Vault to a New Manager

1What a move really is

There is no "change manager" command. The manager address is baked into the vault script on the chain, so moving a vault means: the owner spends the old vault output, then funds a new vault with the new manager's address. Two transactions, both signed by the owner. The old manager is not needed for any of it; the only thing they can do is forget the vault afterwards.

2What it costs

• Two fees of about 0.00003 tDIVI each on testnet (the sweep and the new fund).
• Coin age starts over. Staking weight in Divi grows with how long the output has sat unspent, from zero at its first confirmation up to a cap of seven days (ProofOfStakeCalculator.cpp). The new vault output begins at zero, so expect fewer stakes for the first week. On mainnet the output also cannot stake at all until 20 confirmations.
• Nothing else. No lock, no penalty, no permission from the old manager.

3The five steps, as run on testnet

Owner wallet on Divi Core, old manager on Divi Core, new manager on IronDivi. Addresses: owner y8PL…5Aj, old manager yF5g…dssc, new manager y3D2…Si2a.

Step 1 · Sweep the old vault to yourself

Use sweep_funds on debitvaultbyname so you take exactly that vault and nothing returns to it. Send to an address in your own wallet:

divi-cli -testnet getcoinavailability true
… "vault" : "y8PL…5Aj:yF5g…dssc", "value" : 20.00000000, "txids" : [ "61aa675e…f375" ] …

divi-cli -testnet debitvaultbyname "y8PL1RQSCWYPnJAvhvs6ZwkxfwuB5Ut5Aj:yF5g4mEraodvfjdRE5VrWum9pSF9gMdssc" y8PL1RQSCWYPnJAvhvs6ZwkxfwuB5Ut5Aj 20 sweep_funds
4c56c18b…ae84

(On the day we used reclaimvaultfunds … 20 sweep_funds, which did the same because it was the only vault with coins; debitvaultbyname is safer when you hold several.)

Step 2 · Wait one block

Funding the new vault before the sweep confirms fails with Insufficient funds to meet coin selection algorithm requirements.

Step 3 · Fund the new vault

divi-cli -testnet fundvault "y8PL1RQSCWYPnJAvhvs6ZwkxfwuB5Ut5Aj:y3D2yvmLTwP3Jatsbs7GnqNzEEzkUmSi2a" 19
{
    "txhash" : "3841cd09f7e6db45e91af423b870d6bc0a5040ab85fe74b17a9d4c5935113152",
    "vault" : [ { "encoding" : "y8PL1RQSCWYPnJAvhvs6ZwkxfwuB5Ut5Aj:y3D2yvmLTwP3Jatsbs7GnqNzEEzkUmSi2a" } ]
}

19 rather than 20 because the sweep's fee and the fund's fee come out of the same coins; fund what getbalance shows minus a little.

Step 4 · New manager adds it

irondivi-cli --testnet addvault "y8PL1RQSCWYPnJAvhvs6ZwkxfwuB5Ut5Aj:y3D2yvmLTwP3Jatsbs7GnqNzEEzkUmSi2a" 3841cd09f7e6db45e91af423b870d6bc0a5040ab85fe74b17a9d4c5935113152
{ "message": "Vault … added successfully", "result": "success" }
irondivi-cli --testnet getcoinavailability
{ "Spendable": 50.0, "Stakable": 50.0, "Vaulted": 219.0, "total_vaults": 2, … }

Step 5 · Old manager forgets it (optional)

divi-cli -testnet removevault "y8PL1RQSCWYPnJAvhvs6ZwkxfwuB5Ut5Aj:yF5g4mEraodvfjdRE5VrWum9pSF9gMdssc"
{ "removal_status" : true }

If the old manager is unreachable, skip this. Their wallet will see the output as spent and stop staking it on its own; a stale entry hurts only their housekeeping.

4The same with IronDivi

Steps 3 to 5 work on IronDivi:

irondivi-cli --testnet fundvault "OWNER:NEWMANAGER" 19
<txid>                              # bare txid, no JSON
irondivi-cli --testnet addvault "OWNER:NEWMANAGER" <txid>        # on the new manager
irondivi-cli --testnet removevault "OWNER:OLDMANAGER" <oldtxid>  # on the old manager; needs the old funding txid

5Divi Desktop debug console and BoxWallet

Both run Divi Core, so the owner's steps 1 and 3 are the same two commands typed into the Debug Console (Divi Desktop, on testnet via Settings → Advanced mode → Network) or after ~/.boxwallet/divi-cli -testnet:

debitvaultbyname "OWNER:OLDMANAGER" OWNER 20 sweep_funds
fundvault "OWNER:NEWMANAGER" 19

6Check the new vault

In Explorer 2.0, open the new transaction: 3841cd09…3152 ↗. The vault output lists [owner, new manager]. The old funding transaction 61aa675e…f375 now shows its vault output spent by 4c56c18b…ae84. On the new manager, getstakingstatus shows the staking balance up by 19.
