# Injective FAQ

## Fundamentals

Q: What account address types are supported in Injective?

A: There are two address types supported:

* Bech32 (`inj...`), which is primarily used when interacting via Cosmos wallets/ tools
* Hexadecimal (`0x...`), which is primarily used when interacting via EVM wallets/ tools

Q: How can I convert *hex* addresses to *bech32* addresses?

Addresses can convert between `inj1...` and `0x...` formats in both directions
using `getInjectiveAddress` and `getEthereumAddress` from the Injective TS SDK.
[How to convert between hex and bech32 addresses on Injective](https://docs.injective.network/developers/convert-addresses).

Injective addresses use a *bech32* format: `inj1...`.
They are compatible with EVM addresses which use a *hex* format: `0x...`.
They share the same underlying public key, and are convertible, 1-to-1 and deterministically.

Q: Is there a way to find which Injective Cosmos address is mapped to which Injective EVM address?

A: These address types map to each other through a mathematical operation that is one to one and bidirectional:

* Live example: [Injective Testnet Faucet](https://testnet.faucet.injective.network/)
* Docs: [TypeScript (TS) code examples](https://docs.injective.network/developers/convert-addresses)

## Infrastructure

Q: When maintaining a private node:

* Should you store 2.5 TiB of archival data (event provider)?
* Can you skip that part and make the indexer work?

A: You can prune the event provider. Use the public event provider endpoint for the initial sync, then switch to local deployment from the latest height. Yes, you can skip it.

Q: Which network explorer should I use on Injective?

Use Blockscout for full EVM compatibility,
and use Injscan for full Cosmos compatibility.

Specifically, if you are looking for:

* an [EIP-3091](https://eips.ethereum.org/EIPS/eip-3091)-compatible experience, or

* to use `wallet_addEthereumChain` (or similar) in a dApp,
  ... use Blockscout.
  Otherwise either Blockscout or Injscan will work.

* [Injective Mainnet Blockscout](https://blockscout.injective.network/)

* [Injective Testnet Blockscout](https://testnet.blockscout.injective.network/)

* [Injective Mainnet Injscan](https://injscan.com/)

* [Injective Testnet Injscan](https://testnet.explorer.injective.network/)

## EVM

Q: Does Injective have a deployment of the [`multicall3`](https://www.multicall3.com/) smart contract? {/* tachida2k */}

A: Yes, at the following addresses:

* Injective Mainnet `multicall3`: [`0xcA11bde05977b3631167028862bE2a173976CA11`](https://blockscout.injective.network/address/0xcA11bde05977b3631167028862bE2a173976CA11?tab=contract)
* Injective Testnet `multicall3`: [`0xcA11bde05977b3631167028862bE2a173976CA11`](https://testnet.blockscout.injective.network/address/0xcA11bde05977b3631167028862bE2a173976CA11?tab=contract)
