Connect your wallet
When you click Connect in the top-right of the Kumbaya app, the "How do you want to use Kumbaya?" modal asks you to pick one of two paths. Both are non-custodial - you stay in full control of your funds - but they unlock different parts of the platform.
Kumbaya Wallet (recommended)
DEX + Launchpad + comments + tipping + profile
-
DEX only
Swap + liquidity pools
Launchpad, profile, comments, tipping
You can switch later if you change your mind.
Kumbaya Wallet (Full Access)
This is the path you want if you plan to launch tokens, comment, tip, or have a profile. It uses Privy under the hood, and supports two ways to sign in:
1. With your existing wallet - connect MetaMask, Coinbase Wallet, Rainbow, or any WalletConnect-compatible wallet. Privy attaches your Kumbaya profile to that wallet address. Your assets stay in your wallet; Privy doesn't move them. You sign every transaction in your existing wallet as normal.
2. With email or a social account - Privy creates an embedded wallet for you, tied to your login. You don't install a browser extension, you don't write down a seed phrase. Supported login methods:
Email (passcode sent to your inbox)
Google, X (Twitter), Discord, GitHub, Telegram
After signing in, your Kumbaya profile appears under that wallet - whether it was your existing one or a freshly-created embedded one.
Your private key is never shared with Kumbaya. Embedded-wallet keys are held in Privy's secure infrastructure; only you can authorize transactions. You can export your key at any time if you want to move to a different wallet.
⚠️ Each social-login method gives you a different embedded wallet. Signing in with Google one day and email the next gives you two separate wallets with two separate balances. Pick one method and stick with it (or write down which method you used so you can find your funds again). Connecting an existing external wallet doesn't have this problem - that wallet is yours regardless.
DEX only (Stay Private)
This is the path for traders who only want to swap and provide liquidity, with no social profile or attribution. You connect an existing wallet directly - no Kumbaya account.
Supported wallets: any standard EVM wallet (MetaMask, Coinbase, Rainbow, WalletConnect-compatible).
What works: the swap UI, the pool UI, adding/removing liquidity, collecting LP fees.
What doesn't: launching tokens, claiming a token listing, posting yaps, tipping, building a profile, the launchpad feed actions. If you try to access launchpad-only features, the app will prompt you to switch to the Kumbaya Wallet path.
You can always switch from DEX-only to Kumbaya Wallet later - the modal lets you upgrade without losing your wallet connection.
Switch to MegaETH
Kumbaya runs on MegaETH. The first time you do anything that requires a transaction, your wallet will prompt you to add and switch to the network. Approve the prompt - that's it.
If you want to add it manually:
Network name
MegaETH
Chain ID
4326
RPC URL
https://mainnet.megaeth.com/rpc
Currency symbol
ETH
Block explorer
https://mega.etherscan.io/
For testnet (chain ID 6343), use https://carrot.megaeth.com/rpc and the testnet explorer.
Get some ETH
You'll need a small amount of ETH on MegaETH to pay for gas. Most actions cost a tiny fraction of a cent thanks to MegaETH's design.
Bridge from Ethereum mainnet using Rabbithole, the official MegaETH bridge.
On testnet, grab free ETH from the MegaETH testnet faucet.
Once you've got a balance, you're ready to make your first swap →.
Disconnecting
Click your address in the top-right corner of the app, then Disconnect. Your wallet stays - you're just signing out of this session.
