Restored my seed and my wallet shows testnet: where are my bitcoin?
Seeing a testnet balance after restoring your seed is scary because it looks like your bitcoin are gone, but it's usually just a derivation path pointing at the test network.
A **coin_type 1** in your derivation path means testnet; your real bitcoin are under **coin_type 0**.
Why you see a testnet balance
The derivation path is the route a wallet uses to find your addresses. The second level is the coin_type: 0 for Bitcoin and 1 for the test network, as stated in SLIP-0044 (source: BIP-44 · github.com/bitcoin/bips/blob/master/bip-0044.mediawiki).
If your wallet is set to coin_type 1, it looks at testnet addresses. That's why you can see a balance that isn't yours or looks like play money: you're on the wrong network.
How to confirm it's testnet
Testnet addresses often look different from Bitcoin addresses, but that's not always conclusive. The most direct way is to check if the wallet tells you it's on testnet or if the coins show up as testnet bitcoin.
If you see a small balance or a transaction you don't recognize, don't assume you lost your bitcoin. First check which network the wallet is looking at.
What to check to recover your bitcoin
Look for the derivation path or network option in the wallet. If you can edit it, change the coin_type from 1 to 0 and look again.
If your wallet doesn't let you change the path, try restoring the seed in another wallet that follows BIP-44 and shows the network clearly.
This doesn't tell you which path your wallet used to look at your balance
SLIP-0044 defines the coin_type, but each wallet can use a different derivation path. Seeing a 0 or a 1 in a list doesn't guarantee your wallet is looking at the right network: you need to check the full path and the wallet you restored with.
