A step-by-step guide WeHMND/USDC Here's a comprehensive video tutorial to staking on Humanode Biostaker: {% embed url="" %} ### Step 1. Get HMND on Centralized Exchanges (CEXs) Buy HMND tokens on any of the centralized crypto exchanges. \ \ Centralized exchanges where you can buy HMND.\ [BingX](https://link.humanode.io/trade/bingx) | [KuCoin](https://link.humanode.io/trade/kucoin) | [SimpleSwap](https://link.humanode.io/trade/simpleswap) | [CoinEx](https://link.humanode.io/trade/coinex) Once you get HMND from any exchange, move on to the next step. {% hint style="info" %} For seasoned crypto users only!\ \ You can acquire eHMND from the [Impossible DEX](https://link.humanode.io/trade/impossible-finance) deployed on the Humanode chain or from the Uniswap DEX deployed on Arbitrum if you prefer not to use a CEX. \ \ For Impossible DEX, to buy eHMND, first, you need to bridge USDC from Ethereum to Humanode EVM using the [ChainPort](https://link.humanode.io/bridge/chainport) cross-chain bridge. After bridging USDC, ChainPort airdrops you 5 eHMND, which is more than enough to swap on the DEX. Bridging from the Ethereum Mainnet to the Humanode EVM requires gas fees in ETH.\ \ For Uniswap, you need to first buy eHMND from Uniswap on Arbitrum and bridge to Humanode EVM using the ChainPort cross-chain bridge. {% endhint %} ### Step 2. Swap HMND to eHMND Humanode supports two address formats: native Humanode addresses starting with `hm…` and Ethereum-compatible (EVM) starting with `0x…`. While most of the exchanges support native addresses, to stake you need to move your tokens to an EVM address using the internal swap. {% hint style="info" %} The swap from HMND (Native HMND tokens) to eHMND (EVM version of HMND) is required because LP staking is available on Impossible DEX, deployed on the Humanode EVM version. {% endhint %} To get started:\ \ Transfer native HMND from CEX to your `hm…` address created with [Talisman Extension](https://link.humanode.io/wallets/talisman), if purchased on another exchange. {% embed url="" %} 2. Use the internal [HMND/eHMND swap](https://evm-playground.mainnet.stages.humanode.io/swap/native-to-evm) to convert HMND to eHMND. Connect your Talisman wallet ( Humanode address) and connect or just paste your Ethereum-compatible address to receive eHMND.\ ![](/files/n51AN9LX1ZCNVDvliztj)\ You can use either Talisman or Metamask for the Ethereum-compatible address.\ ![](/files/RxaoP4Uv9RSq4PpvHvE7) ### Step 3. Swap eHMND to USDC After acquiring eHMND, swap almost 50% of it for USDC on [Impossible Finance](https://link.humanode.io/trade/impossible-finance), keeping about 20 eHMND aside for future network fees. This is required since we need USDC and eHMND to obtain LP tokens. {% hint style="info" %} For sophisticated crypto users! Skip this step if you already bridged USDC from Ethereum. {% endhint %} Here's how you can do it: 1. On the [Impossible Finance swap](https://link.humanode.io/trade/impossible-finance), Connect your wallet. Make sure you switch to Humanode Mainnet on your wallet.\ ![](/files/OBzSk6dg5hlVx0Br7aqi)![](/files/eSIVXNqnB1d5HAzTKOlT) 2. Select WeHMND (Wrapped eHMND) in the `From` field and USDC in the `To` field and enter the number of tokens you want to swap.\ ![](/files/hqJE1XIA0PkCmsI1Th9N) 3. Approve Spending on your wallet.\ ![](/files/hqJE1XIA0PkCmsI1Th9N) 4. Swap the Approved amount of WeHMND to USDC.\ ![](/files/ftWpDU6K3xneibCz5HZ1) {% hint style="info" %} Swapping requires a network fee. {% endhint %} ### Step 4. Add liquidity / Pool WeHMND/USDC Now you are ready to provide Liquidity to Impossible Finance DEX. To do that, add WeHMND and USDC to the WeHMND/USDC pool on Impossible Finance DEX. In return, you will receive Liquidity Provider (LP) tokens that represent the value of your assets. {% hint style="info" %} For pooling, keep the same $ amount of USDC and WeHMND in your wallet address. {% endhint %} To [Add liquidity](https://link.humanode.io/trade/impossible-finance/add-liquidity): 1. On the [Biostaker app](https://mainnet.biostaker.hmnd.app/biostaker/0xe9547763Baf3C89ba832bb912e6F3472cfC98402), Click "Add Liquidity"\ ![](/files/s9H2URwVm7eMcKmzDqfe) 2. You'll be directed to the [Impossible Finance](https://link.humanode.io/trade/impossible-finance/add-liquidity) Dapp. Enter the amount of WeHMND & USDC tokens you wish to add to the liquidity pool.\ ![](/files/y5sQu2YZfiCKfDyxcHVD) 3. Approve spending USDC & WeHMND on your wallet.\ ![](/files/NWHSbcb8hoEiyidxEPJl) 4. Supply the approved amount to the liquidity pool.\ ![](/files/Bc2UeCxuVNocj3apBW7t) 5. Confirm Supply and Add LP tokens WeHMND/USDC to your wallet.\ \ ![](/files/ChdtdQxfm7Ldyeng0yVZ) ![](/files/KobPUNMLsQh4NMirwV7n) ### Step 5. Biomap your EVM address and Stake LP tokens Next, link your EVM address to your biometrics through a [private face scan](https://blog.humanode.io/data-privacy-and-protection-in-botbasher/) safeguarded by Humanode's cryptobiometric technology to prove you are a unique human. Unlike KYC, it doesn't require any personal information about you. {% hint style="info" %} Biomapping is essential as it ensures one account per person, making the staking process Sybil-resistant and the new reward scheme possible. {% endhint %} 1. Visit the [Humanode Biostaker app](https://mainnet.biostaker.hmnd.app/), connect your wallet, and select 'BIOMAP' \ ![](/files/ZCm5gSahrdPuzs6w4kPi) {% hint style="info" %} 1. Ensure you connect the wallet address you'll use for staking as biomapping is irreversible – an EVM address once linked to your biometrics cannot be reassigned to a different address. 2. Biomapping requires 2 eHMND + a network fee. {% endhint %} * Accept the Terms and Privacy Policy.\ ![](/files/vg0NyhquaAwrwDXugiW1) * Complete the face scan\ ![](/files/pIAx6TmPa6Wr6j77iZrO) * Connect Wallet and Submit Transaction. \ ![](/files/fYHu6OPodgkOuwl3Etql) 2. Once you've biomapped your address, stake WeHMND/USDC LP tokens on the Biostaker app. Just click Max in the `Tokens to stake` field, `Approve Spending`, and Confirm in your wallet. You can then view and manage your staked tokens and rewards in the Biostaker app.\ ![](/files/QMmu6JuD3Fh03PMQtA8u) {% hint style="info" %} ***Congratulations!
