Let’s assume you have a server set up already, with docker installed. This Quickstart will guide you through setting up and running mango-explorer to run a liquidator on Mango Markets. (You’ll need to provide your own funds for the liquidator though!)
Throughout this guide you’ll see the private key, accounts and transaction IDs as well as the commands and parameters that are used. (Funds will be removed from this account before this is published. Remember - sharing your private key is usually a Very Bad Idea!)
OK, now is the time to question if you should really do this. No-one here is going to take any responsibility for your actions. It’s all on you. Are you certain you want to do this? Are you sure you want to run this code? Have you even checked it to make sure it’s not going to steal your money? Are you aware of the risks from markets in general, plus bugs, developer incompetence, malfeasance and lots of other bad stuff?
To run this quickstart you’ll need:
- A server set up with docker or podman installed and configured.
- Some SOL for transaction costs.
- Some Solana-based USDC (we'll convert USDC to other tokens in this Quickstart).
Liquidation is the process that provides security to Mango Markets. Any accounts that borrow funds create the risk that they may not be able to pay those borrowed funds back. Accounts must provide collateral before they borrow funds, but the value of that collateral can vary with the price of the collateral tokens and the borrowed tokens.
If the value of the borrowed funds were to exceed the value of the provided collateral, all Mango Markets users would have to cover those losses.
To prevent this, accounts have to provide collateral worth more than they borrow. Values are allowed to vary a little, but if the value of the collateral falls to lower than a specified threshold of what the account borrowed, that account can be 'liquidated'. (Current values for these thresholds are: you must provide collateral worth over 120% of your borrowings, and if the value of your collateral falls below 110% you can be liquidated.)
Being 'liquidated' means someone - anyone - can 'pay off' some of the borrowed tokens, in return for some of the collateral tokens. This 'paying off' earns the liquidator a premium of 5% - that is, 5% more collateral tokens are returned than the value of the borrowed tokens, making it a worthwhile task for the liquidator.
For more details of the process and what it involves, see the Liquidation notebook.
This Quickstart will use 1,000USDC as the starting point. Is this enough? Too much? It all depends on you, how much you have, and how much you want to allocate to the liquidator.
1,000USDC seemed a nice starting point for this guide, but how much you use is up to you. Adjust the figures below where necessary.
Our server will keep all its files under /var/mango-explorer, so run the following commands to set up the necessary directories and files:
# mkdir /var/mango-explorer
# touch /var/mango-explorer/id.json
# chown 1000:1000 /var/mango-explorer/id.json
(Don’t type the # prompt - that’s to show you the unix prompt where the command starts.)
Next, we'll set up an alias to make running the container easier. There are a lot of parameters to the
docker command and they're the same every time so to save typing them over and over, run:
# alias mango-explorer="docker run --rm -it --name=mango-explorer \
-v /var/mango-explorer/id.json:/home/jovyan/work/id.json \
opinionatedgeek/mango-explorer:latest"
Alternatively if you're using podman instead of docker, run this:
# alias mango-explorer="podman run --rm -it --name=mango-explorer --security-opt label=disable \
-v /var/mango-explorer/id.json:/home/jovyan/work/id.json \
opinionatedgeek/mango-explorer:latest"
Run the following command to create your wallet:
# solana-keygen new --force --outfile /var/mango-explorer/id.json
This will ask you for a passphrase to protect your wallet - just press ENTER for no passphrase (mango-explorer doesn't work with passphrases on key files yet and no-one has asked for it).
The output will be something like the following:
Generating a new keypair
For added security, enter a BIP39 passphrase
NOTE! This passphrase improves security of the recovery seed phrase NOT the
keypair file itself, which is stored as insecure plain text
BIP39 Passphrase (empty for none):
Wrote new keypair to /Users/geoff/idx.json
=========================================================================
pubkey: uVBU7j2VGqNKLrYFfCcbU71sopkD4nW58Rk7CTyEYFm
=========================================================================
Save this seed phrase to recover your new keypair:
artist stadium topple few dawn quit group worry mother banner shadow term
=========================================================================
That's what a successful run of the command looks like.
This will create a Solana wallet and write its secret key to /var/mango-explorer/id.json. Looking after this file is entirely your responsibility. If you lose this file, you lose the private key for all the funds in the wallet. If you give it to someone else you give them the entire contents of your wallet.
Once successfully created, if you look at the file you’ll see the bytes of your private key. Keep this secret!
It should look something like this, but with different numbers:
# cat /var/mango-explorer/id.json
[110,49,211,169,16,1,52,50,225,133,73,175,67,185,69,124,79,194,153,3,53,41,204,180,255,80,44,140,43,222,6,53,13,114,16,218,159,70,85,72,57,243,132,149,4,117,23,61,10,101,43,62,61,1,216,197,55,59,237,8,106,171,135,60]
Yes, that's the actual secret key of the account.
Transfer some SOL into the account just created. SOL tokens are needed for running operations on the Solana blockchain, similar to the way ether is used on Ethereum.
How you transfer the SOL is up to you, and dependent on where you actually have SOL.
I used sollet to transfer 1 SOL to 48z8UzFTYYbmFGgryA3muJ4tjdPsDUnB84YvfCXtv4dB, the address shown above when creating the wallet. When the transfer completes (it’s very fast!) it appears in the wallet and you can check that using the group-balances command:

These five tokens - BTC, ETH, USDC - are the five tokens of the default 'group' of cross-margined tokens we're using. If you want to use a different group, you can pass the --group-name parameter to commands.
Now let's examine our account with the Account Scout. This tool is used to verify things on liquidator startup, and it's useful to run from time to time.
If you run it without parameters it will check the current wallet address, but you can check a different address by passing the --address parameter.

So, we have 5 errors - no token accounts for BTC, ETH, SOL, SRM, or USDC. That's expected - we haven't added any of those tokens yet. Let's start that now.
Transfer some USDC to the new account. Again I'm using sollet for this but you use whatever you're comfortable with. I transferred 1,000 USDC to 48z8UzFTYYbmFGgryA3muJ4tjdPsDUnB84YvfCXtv4dB.
When you've transferred the USDC, a re-run of the group-balances should show something like:

Balances:
SOL balance: 1.00000000
BTC balance: 0.00000000
ETH balance: 0.00000000
SOL balance: 0.00000000
SRM balance: 0.00000000
USDC balance: 1,000.00000000
You can see above that the USDC balance is now 1,000. You should see whatever amount you transferred in your own output.
The default group is a cross-margined basket of 3 tokens: BTC, ETH, and USDC. A general liquidator probably wants to be able to provide any of those tokens, to allow for situations where it needs to provide tokens to make up a margin account's shortfall.
After performing a liquidation though, the wallet may 'run out' of one type of token, or may have too much of another token, skewing the risk profile of the wallet. To fix this, we need to 'balance' the proportion of each token in the wallet.
What proportion of tokens is 'right'? It depends on your goals. You might want to accumulate only USDC, so you would specify a fixed amount of BTC and ETH as the target for balancing. On the other hand, you may just want to keep a third of the value in each token.
For our purposes here, let's go for about a fifth in each token. At today's prices, that's:
- 0.004 BTC
- 0.06 ETH
- 2.65 SOL
- 30 SRM
- 200 USDC
To set this up, we can use the group-balance-wallet command. We tell it we want to put 33% in BTC (using the --target parameter with the value "BTC:33%") and 33% in ETH (using the --target parameter with the value "ETH:33%"). Since this command actually performs transactions, let's run it first with the --dry-run parameter - this tells the command to run but not send any actual transactions to Serum.
# mango-explorer group-balance-wallet --target "BTC:0.004" --target "ETH:0.06" --target "SOL:2.65" --target "SRM:30" --dry-run

If you have problems at this stage, for example with Solana transactions timing out because of network problems, there are useful commands to manually fix things: serum-buy, serum-sell and (particularly useful for problems where Serum completes the order but the token doesn't make it to your wallet) group-settle.
Now if we check the balances we can see we have roughly a fifth in each of the five group tokens:

You can see that the process of balancing the tokens has created the necessary token accounts, as well as creating the OpenOrders accounts Serum uses for trading.
All looks good now!
OK, now we're ready to try a test run of the liquidator.
This is a long-running process, so we'll need to use Control-C to cancel it when we're done.
Here goes:
# mango-explorer liquidator --target "BTC:0.004" --target "ETH:0.06" --target "SOL:2.65" --target "SRM:30" --dry-run

Well, that all seemed fine.
Some important things to note from the simulated run:
- It does a bunch of checks on startup to make sure it is in a state that can run.
- It prints out some summary information about the wallet account and child accounts.
- It loops once per minute, assessing which margin accounts are liquidatable (none, in the above run)
- It sleeps for as long as it can between runs
- You can't see it in the above (because no liquidations occurred) but it will automatically balance the wallet after every liquidation.
Remember that section on ☠️ Risks above? Well, if you still want to do it - and I’m not recommending you do - you can have liquidator submit live orders by removing the --dry-run parameter.
Output should be broadly the same as the output for a 'dry run', but if it sees any worthwhile liquidatable accounts it should try to perform a partial liquidation.
Now, it's over to you. Happy liquidating!
