Setup Instructions

Managing wallets for MANTRA on both COSMOS and EVM requires a bit of nuance.

A WORD OF CAUTION!

Managing wallets and sending messages for MANTRA to be processed by native COSMOS/WASM and EVM is somewhat complex at the moment and NOT production-grade.

Overview:

1. Create your wallet, either using Keplr or Metamask.

2. Configure Metamask to show native OM Balance

3. Working with mantrachaind

4. (Optional) Keplr Setup Notes

Wallet Creation

From Scratch

Creating a wallet from scratch is fine and can be done via Metamask or Keplr, after which, the PRIVATE KEY should be exported and imported to the alternative relevant locations as needed.

The private key will also be required for most contract deployments via Hardhat and Foundry anyway.

Importing Existing Wallets

It is recommended to use the private key export of any wallet that you wish to import; seed phrases may not derive the correct private key in plugins such as Metamask and Keplr.

Metamask Setup

For the time being - using Metamask is the ideal scenario as it can render balances correctly for EVM and for MANTRA Chain (OMSTEAD) OM

1. Open Metamask and from top-right corner select the network dropdown to add custom network per the specs below:

Network Name	MANTRA-OMStead-EVM
RPC URL	https://evm.omstead.io
Chain ID (EVM)	7888
Currency Symbol	OM

1. Switch to MANTRA-OMStead-EVM network and you should see native OM token balance

Importing into Mantrachaind Keyring

1. Download and configure the relevant mantrachaind binary from https://github.com/MANTRA-Chain/mantrachain/releases/tag/v5.0.0-evm-alpha.10

2. Using the mantrachaind keys add command, you can import the relevant seed phrase or private key into the command line and manage from there. Note that the default --coin-type in cli is 60

3. Bank balances commands should have --node and the relevant URL specified.

Keplr Setup (Optional)

CoinType ISSUES

To align with metamask address derived from mnemonic, we decide to use cointype 60 to derive the both cosmos and evm address in Keplr's suggestChain.

1. Navigate to https://explorer.omstead.io/wallet/suggest

2. Select Keplr in the top and that will allow it to add the network to your extension: MANTRA-OMStead

3. Keplr will add both cosmos and evm addresses sequentially.

4. Then you can add the token above
