I know most of us have MetaMask or Ledger wallets already. But here’s simple guide on how you can actually use them to connect with the @dYdX Chain v4 and start trading: 👇

Let’s, first understand:
dYdX v4 is no longer on Ethereum, now it runs its own sovereign Cosmos-based chain.

So, MetaMask doesn't connect natively. But there's a solution:👇

👉 To use MetaMask with dYdX v4:

- First use the Keplr wallet,

Then use MetaMask to sign in via Ethereum for account linking
This links your MetaMask address to your dYdX Chain account. 

👉 Now understand why not direct MetaMask?🤔

- Because MetaMask doesn’t support Cosmos SDK chains like dYdX v4 directly. So dYdX uses MetaMask only as an auth layer signing login or auth messages. 
———————————————

🔵 Steps for MetaMask login on dYdX:

🔹Visit

🔹Click Login. Then choose Ethereum wallet. 

🔹 Connect MetaMask & sign(signup confirmation msg will pop up on in app)

🔹Last step: link to a Cosmos address like Keplr. And you ou're in. 😊
————————————————
👉 Now, for Ledger users:

Ledger is supported natively on Keplr. That means you can directly manage your dYdX Chain account through a Ledger hardware wallet via Keplr.

🔵 Using Ledger with dYdX is the most secure way:

🔹Open Keplr

🔹Connect your Ledger

🔹Access dYdX with the Cosmos address derived from Ledger

🔹Trade & sign securely with the hardware wallet.

🔵 Start your dYdX journey here:

And always double-check you’re on the correct domain before connecting your wallet.
