# Wallet setup

> Add Robinhood Chain (4663) to your wallet, fund it with ETH for gas, and connect to Archr.

The same wallet setup applies whether you plan to launch a coin, buy one, or hold ARCHR.

## 1. Install a supported wallet

Archr uses [ConnectKit](https://docs.family.co/connectkit) on top of [wagmi](https://wagmi.sh), so every browser-injected EVM wallet the adapter supports will connect. MetaMask and Rabby are the two you are most likely to have; either works the same once connected.

* **MetaMask** ([metamask.io](https://metamask.io)). Browser extension on Chrome, Brave, Firefox, Edge; iOS and Android apps.
* **Rabby** ([rabby.io](https://rabby.io)). Browser extension with a stronger transaction-preview UI.

Install the extension, create a wallet, and write down the seed phrase on paper. Never share it and do not paste it into a cloud-synced password manager.

## 2. Add Robinhood Chain (4663)

Archr lives on Robinhood Chain mainnet, chainId **4663**. If your wallet does not have it pre-listed, add it manually:

| Field           | Value                                      |
| --------------- | ------------------------------------------ |
| Network name    | Robinhood Chain                            |
| Chain ID        | `4663`                                     |
| RPC URL         | `https://rpc.mainnet.chain.robinhood.com/` |
| Currency symbol | ETH                                        |
| Block explorer  | `https://robinhoodchain.blockscout.com`    |

For the canonical Robinhood Chain documentation and alternative RPC endpoints (including keyed Alchemy access) see [Robinhood's protocol contracts page](https://docs.robinhood.com/chain/protocol-contracts).

Adding the network by hand is optional. The site auto-prompts a network switch when you connect.

## 3. Fund the wallet with ETH

Robinhood Chain uses native ETH for gas. Bridge ETH from Ethereum mainnet via the [Robinhood Chain bridge](https://docs.robinhood.com/chain); the canonical L1 bridge contracts are listed on Robinhood's docs site. A small amount is enough for launching or trading: a launch transaction from the site costs on the order of 0.005–0.01 ETH.

## 4. Connect and verify

Open [archr.win](https://archr.win) and click **Connect Wallet**. Approve the connection in your wallet, then check that:

* The header shows your address truncated.
* The chain indicator reads Robinhood Chain (4663). If it does not, switch networks in the wallet; every write action on Archr assumes 4663.

You are ready. Head to [your first launch](/getting-started/first-launch-site) to deploy a coin, or [trading overview](/trade/overview) to buy one. Read the [risks](/reference/risks) before you commit real funds.
