Setup

In order to get started with the Auction House CLI please follow these steps.

Create

Creates an Auction House

See the command help with

ts-node auction-house-cli.ts help create_auction_house

Find your current Keypair, lets say it lives at ~/mywallet.key or on Windows C:\Users\windowsuser\mywallet.key. To create an Auction House you will run.

ts-node auction-house-cli.ts create_auction_house --keypair ~/mywallet.key -e devnet -sfbp 1000 -ccsp false -rso false

In this case we don't need to require sign-off because we want to make a fully decentralized auction house. Since we did not specify -tm, --treasury-mint <string> The currency for payment will be SOL. Also, the options below will default to being set as the public key of ~/mywallet.key

-twd, --treasury-withdrawal-destination <string>
-fwd, --fee-withdrawal-destination <string>

If all goes well you will see

wallet public key: Gsv13oph2i6nkJvNkVfuzkcbHWchz6viUtEg2vsxQMtM
No treasury withdrawal dest detected, using keypair
No fee withdrawal dest detected, using keypair
No treasury mint detected, using SOL.
Created auction house HsKwc8dQtm8KLxshw67dwsNePkH6wMXo5Lwn1FuKjVYVS <--- Your auction house key will be different

Save this key HsKwc8dQtm8KLxshw67dwsNePkH6wMXo5Lwn1FuKjVYVS since it is the public key of the solana account that holds your Auction House. In all subsequent commands you will pass this key with the -ah option.

Show

Prints the balances of the fee and treasury wallets configured for the auction house and its current settings options.

See the command help with

ts-node auction-house-cli.ts help show

Notice I switched --keypair for -k this is shorthand but works just the same.

ts-node auction-house-cli.ts show -k ~/mywallet.key -ah HsKwc8dQtm8KLxshw67dwsNePkH6wMXo5Lwn1FuKjVYVS

The output will differ but similar to the following.

No treasury mint detected, using SOL.

Fee Account

In the above Show command you see a Fee Payer account. This account can be used to pay the fees on chain for sales execution, transfers and account creation. For this exercise we will teach you how to fund that account by airdropping some SOL on devnet. Your Auction House fee account is used only when the Auction House authority is signing the transaction. This is usually only in the case of Requires Sign Off

$ solana airdrop 2 AcWpR41NPMq73FZUspCiXxoLrJnW7zytgHKY5xqtETkU
Requesting airdrop of 2 SOL

2 SOL

The solana airdrop command is sometimes unreliable. If the command doesn't work, you can use the airdrop tool at https://solfaucet.com.

Sell

Place an NFT UP for sale.

See the command help with

ts-node auction-house-cli.ts help sell

Place an NFT for sale by its mint address with the auction house for 1 SOL.

ts-node auction-house-cli.ts sell \
  -k ~/mywallet.key \
  -ah HsKwc8dQtm8KLxshw67dwsNePkH6wMXo5Lwn1FuKjVYVS \
  --buy-price 1 \
  --mint F7fejo7cT1fRyJxj1W2aWy3aeJz8iqLU9YvbBAzwJGh2 \
  --token-size 1

Output:

Require Sign-off

If the auction house is set up to require sign off its wallet, as well as the seller are provided to the command. Do this using the -ak option.

See the command help with

ts-node auction-house-cli.ts help sell

In a production scenario where the keypair for the auction house is stored on a sever managed by the organization hosting the auction house the transaction should be partially signed by the seller from the client then passed to the server for signing by the auction house before submitting to Solana.

Buy

Place an offer on an NFT by its mint address at some price in SOL when using native SOL as the mint.

See the command help with

ts-node auction-house-cli.ts help buy

The buy command is an offer on the NFT and will not result in a sale until the execute_sale action is triggered. This command offers 2 SOL for the NFT.

ts-node auction-house-cli.ts buy \
  -k ~/mywallet.key \
  -ah HsKwc8dQtm8KLxshw67dwsNePkH6wMXo5Lwn1FuKjVYVS \
  --buy-price 2 \
  --token-size 1 \
  --mint 7v8kcqCHLih31bp2xwMojGWTMdrcFfzZsYXNbiLiRYgE

wallet public key: DCDcpZaJUghstQNMHy9VAPnwQe1cGsHq7fbeqkti4kM3
Made offer for  2

Execute Sale

Sell an NFT to a buyer at the price set by the seller. Note that this currently requires the auction house authority, the buyer, or the seller to be the fee payer and thus sign the transaction.

$ ts-node auction-house-cli.ts execute_sale
  -k ~/mywallet.key \
  -ah HsKwc8dQtm8KLxshw67dwsNePkH6wMXo5Lwn1FuKjVYVS \
