Meltan & Mystery Box Guide
Link Pokémon HOME to unlock Mystery Boxes, farm Meltan Candy efficiently, and evolve into Melmetal.
Meltan
Meltan · No.808 · Hex Nut Pokémon · Steel
A Mythical Pokémon obtainable only through the Mystery Box, which you receive by transferring Pokémon to Pokémon HOME.
Basic Info
How to get the Mystery Box (6 steps)
No Nintendo Switch and no paid membership required — mobile-only is enough. Setup is one-time; afterwards just repeat STEP 3 and 6.
STEP 1 · Install Pokémon HOME (mobile) + sign in with Nintendo Account
Install Pokémon HOME on iOS/Android and sign in with a Nintendo Account. You can create a free Nintendo Account inside the app if you don't have one (email verification required). A Switch console or game is NOT required.
STEP 2 · Link Pokémon GO with Pokémon HOME
In Pokémon GO, open the Trainer menu → Settings → "Connected Devices and Services" → "Pokémon HOME" → sign in with the same Nintendo Account from STEP 1. ⚠️ Even if you log into Pokémon GO with Trainer Club/Google/Facebook, the HOME link uses a separate Nintendo Account — that's normal and your game data stays intact.

STEP 3 · Send 1 Pokémon via the GO Transporter
In the same menu (Settings → Pokémon HOME), tap "Send Pokémon" to open the GO Transporter. Pick a Pokémon and send it. Energy is full on first use and recharges over time (or instantly with PokéCoins).

STEP 4 · Mystery Box appears in your Bag
Once the transfer succeeds, the Mystery Box is automatically added to your Pokémon GO Bag — no extra "claim" step is needed. New trainers should see an "A Mystery Box has been added" notification.

STEP 5 · Receive the Pokémon in HOME (mobile)
Open the Pokémon HOME app → Settings → "Pokémon GO Link" → "Receive" to move the transferred Pokémon into your HOME boxes. ⚠️ Free HOME storage is capped at 30 — release Pokémon before it fills up. Since the Mystery Box was already added in STEP 4, postponing this step doesn't affect box usage.

STEP 6 · Use the Mystery Box → Meltan appears for 60 min
Tap the Mystery Box in your Bag → "Use" to make Meltan appear around you for 60 minutes. After use there's a 72-hour (3-day) cooldown plus another transfer required, so make sure your prep (Silver Pinaps, Steel Mega, Buddy = Meltan) is done before activation.

Common pitfalls
GO account ≠ Nintendo AccountEven if you use Trainer Club, Google, Apple, or Facebook to log into Pokémon GO, HOME linking requires a separate Nintendo Account. Creating one is free and won't affect your GO data.
Pokémon you cannot transferFavorited (⭐), Buddy, Pokémon defending Gyms, costumed Pokémon, Shadow Pokémon, Mega-Evolved Pokémon, and Pokémon caught in special Poké Balls cannot be transferred. Try with a regular wild catch. (Lucky/Purified Pokémon transfer but lose that status.)
First box is instant; afterwards 72-hour cooldownThe first Mystery Box from your initial transfer is usable immediately. After each use you must wait exactly 3 days AND send another Pokémon to receive the next box. Boxes don't stack — use them as soon as you get them.
GO Transporter EnergySending many Pokémon at once drains energy fast. If you only care about the Mystery Box, sending 1 Pokémon per cooldown is the most efficient.
"Could not connect to Pokémon HOME" errorIf this error appears in GO right after linking, open the Pokémon HOME mobile app once to verify the GO link from there, then retry in GO. This happens when the link test on your device hasn't completed before transferring (the most common first-time failure).

Candy farming tips
400 candy are needed to evolve into Melmetal. Use these tips to farm efficiently.
A Silver Pinap Berry doubles candy on catch. Stock up on Silver Pinap Berries before using a Mystery Box.
Activating a Steel-type Mega (Mega Scizor, Mega Garchomp, etc.) grants +1 candy when catching Meltan.
Using it during Snow weather (Steel boost) spawns higher-CP Meltan, giving more catch XP too.
Set Meltan as your Buddy and walk — you gain 1 extra candy per 20 km.
Transfer or trade extra Meltan to convert them into candy.
