MetaMask and other ERC20 wallets default to Ethereum mainnet, therefore your wallet is almost certainly pointing to Ethereum by default.

## Local / Ganache
The most straightforward way for local-only development is to use [Barge](https://www.github.com/oceanprotocol/barge), which runs [Ganache](https://www.trufflesuite.com/ganache), Aquarius, and Provider. It is used extensively by the Ocean core devs (with Ganache or Rinkeby) and for automated integration testing.
@ -151,11 +193,15 @@ To connect to it from MetaMask, select the network called _Localhost 8545_.
Alternatively, you can run Ganache independently. Install it according to [the Ganache docs](https://www.trufflesuite.com/ganache). Then deploy Ocean contracts onto Ganache following [docs in Ocean contracts repo](https://www.github.com/oceanprotocol/contracts). Ganache is at the RPC URL [http://localhost:8545](http://localhost:8545).
**Get Tokens**
**Tokens**
- ETH: By default, Ganache creates several Ethereum accounts at launch, gives each some ETH, and makes their private keys available in the logs. You can also instruct Ganache to give ETH to specific Ethereum addresses.
- OCEAN: You can deploy an ERC20 token with label OCEAN. At a minimum, the token needs to be ERC20Detailed and ERC20Capped. You’ll see examples in the quickstarts for the Ocean JavaScript and Python drivers.

## Chain IDs
## Other
Some apps may need `network_id` and `chain_id`. Here's a [list of values for major Ethereum networks](https://medium.com/@piyopiyo/list-of-ethereums-major-network-and-chain-ids-2bc58e928508).

@ -27,7 +27,7 @@ Once your wallet is set up, it will have one or more **accounts**.
Each account has several **balances**, e.g. an Ether balance, an Ocean Token balance, and maybe other balances. All balances start at zero.
An account's Ether balance might be 7.1 ETH in the Ethereum Mainnet, 2.39 ETH in Ropsten testnet. You can move ETH from one network to another only with a specially setup exchange or bridge. The same is true of OCEAN token balances.
An account's Ether balance might be 7.1 ETH in the Ethereum Mainnet, 2.39 ETH in Ropsten testnet. You can move ETH from one network to another only with a specially setup exchange or bridge. Also, you can't transfer tokens from networks holding value such as Ethereum mainnet to networks not holding value, ie testnets like Ropsten. The same is true of OCEAN token balances.
Each account has one **private key** and one **address**. The address can be calculated from the private key. You must keep the private key secret because it's what's needed to spend/transfer ETH and OCEAN (or to sign transactions of any kind). You can share the address with others. In fact, if you want someone to send some ETH or OCEAN to an account, you give them the account's address.
