Mint faster than a person can.

When a new NFT collection launches, it usually goes on sale at a fixed time with a fixed supply. Everybody presses buy at the same second. Most of them are pressing it by hand. If the collection is any good, it sells out in seconds and the people who got in first are the only ones who got in at all.

That is the whole game, and it is a timing game. SolidFlow does three things a person cannot:

Chains it works on

Read straight from the bot's own list, so this table cannot drift from what the bot actually supports.

The first time you open the bot it offers a dry run(a full rehearsal on a test network, where the money is not real). Take it. It runs the entire sequence end to end so you can see what the screen does before anything is at stake.

1. 1

   Open the bot

   Go to solidflow.co. It is a web page, not an app.
2. 2

   Press Run dry-run

   The offer appears on first open. If you skipped it, it is still there under the wallet sheet.
3. 3

   Watch the log

   You will see the same sequence a real mint uses: checking the contract, arming, firing, and a result per wallet.

A seed phrase(a list of words that is the master key to a set of wallets) is the only thing you need to recreate every wallet the bot uses. Anyone who has it has your money, so it never leaves your device and SolidFlow never receives it.

1. 1

   Open the wallets sheet

   Tap Wallets in the cockpit.
2. 2

   Create a set, or import one

   Create set makes a new seed phrase for you. Import takes one you already have. Choose how many wallets to derive, typically four to eight.
3. 3

   Set a passphrase

   This encrypts the keys on your device. It is not the seed phrase and it is not recoverable. Write it down.
4. 4

   Turn on Face ID or fingerprint

   Optional but worth it. It unlocks the set with one scan instead of typing the passphrase before every race. The name on the button matches whatever your device actually has.
5. 5

   Fund them from a cold wallet

   Send each mint wallet enough for the mint price plus gas, on the chain the sale is on. The bot will tell you which wallets are short before it arms.

Something has to hold the keys and sign the purchases. That thing is called the signer(whatever holds your keys and signs transactions). SolidFlow never does. You choose where it runs.

You can change your mind later. The wallets are the same wallets whichever one holds them, because they all come from the same seed phrase.

1. 1

   Paste the contract address

   The long 0x… string for the collection. The project publishes it. The bot works out which chain it is on by itself.
2. 2

   Wait for the check

   It reads the contract and runs a simulation(a pretend purchase, to see whether a real one would work). You are looking for Sim passed · ready. This costs nothing and touches nothing.
3. 3

   Choose how hard to push

   Safe, Fast or Nuke decide how much you are willing to pay in gas to get in. See the table below.
4. 4

   Choose how many, and from which wallets

   Qty is per wallet. Check the sale's own limit first: asking for more than it allows usually makes the whole purchase fail.
5. 5

   Arm, or Fire

   If the sale is already open, Fire sends now. If it opens later, Arm · wait for open prepares everything and waits.

The three gas settings

On most chains, paying a higher fee gets you processed sooner. These are the three levels, and the right one depends on how contested you think the sale is.

This is the page to come back to. The bot says exactly one thing at a time, and each of them means something specific.

Before you arm

While it is running

When it is over

Most good mints open at an announced time, often in the middle of your night. You do not have to be there.

Press Arm · wait for open and the bot prepares and signs everything immediately, then waits. When the moment comes there is no work left to do, only a send. It fires against the chain's own clock, which is what actually decides who was first.

If you are arming from a phone

An allowlist(a list of wallets allowed to mint early or at all) is checked by the contract using a small piece of cryptographic evidence called a proof. Without it, the purchase is rejected.

There are three ways to give the bot what it needs, in order of preference:

When a purchase lands, the bot reads the receipt and shows the token numbers, per wallet. That matters because you cannot sell, send or price a token whose number you never wrote down.

3 tokens · #4211–4213

It also records how long after the sale opened your purchase actually landed. If that number is large, something is slow, and the troubleshooting table covers what.

Press Sell next to what you won. The bot reads three things from the chain before it shows you anything: whether the collection charges a royalty(a cut of every sale that goes to the creator), whether anything is allowed to move your token yet, and the state of your wallet's order history.

1. 1

   Type a price

   The bot shows what you would keep after the royalty and the marketplace fee, and the price you would need to break even on what the mint cost you.
2. 2

   Approve the collection, once

   A sale has to be able to move the token, and that takes one transaction per collection, ever. The bot tells you if it is needed and prepares it.
3. 3

   Sign the listing

   You see one sentence describing exactly what you are authorising before you sign it. Read it.

You do not have to find mints yourself. SolidFlow watches every chain it supports for the exact moment a collection starts minting, including ones nobody announced, and scores what it finds.

The licence is checked against the first wallet of your seed phrase. Paying once covers every other wallet derived from the same phrase, so a set of eight is one licence, not eight.

1. 1

   Mint wallets are spending money

   Keep nothing in them you would miss. Top them up before a mint and move winnings out afterwards.
2. 2

   Your seed phrase goes in one place, once

   Into the bot's own wallet sheet. Never into a link somebody sent you, never into a form, never into a chat. SolidFlow will never ask for it anywhere else.
3. 3

   Never arm an unverified contract

   If the code is not published, nobody can tell you what it does with your money. The status says so plainly.
4. 4

   Check the quantity limit before you set Qty

   Asking for more than the sale allows usually fails the whole purchase, and you still pay the gas.
5. 5

   A fast bot into a bad mint is still a bad mint

   Speed is the only thing here that is solved. What to buy is not.
