Wallet setup

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 on top of wagmi, 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). Browser extension on Chrome, Brave, Firefox, Edge; iOS and Android apps.
• Rabby (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: For the canonical Robinhood Chain documentation and alternative RPC endpoints (including keyed Alchemy access) see Robinhood’s protocol contracts page. 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; 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 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 to deploy a coin, or trading overview to buy one. Read the risks before you commit real funds.
