beta-2 network is launched with a bridge to Ethereum's Goerli test network. With this network, developers are able to build and test cross-chain dapps, laying the foundations for projects building on Fuel to tap into Ethereum's massive liquidity and existing user base.
Ethereum contracts (Goerli):
The ERC-20 Gateway contract on Georli Ethereum is at
You can view a test ERC-20 token contract at
0x9c3f3a5a53bD127a51Ae9622EC43488FE6a4DcCd on Goerli Ethereum with the corresponding Fuel side token contract deployed at
0x250cbf149be078027eed12eba0fe07617b398ccc8ccf1f43a02adddd4e4f8e56 on the
Goerli block explorer: https://goerli.etherscan.io/
🚰 Faucet - Use the faucet to get test ETH to deploy contracts with or to interact with contracts. Available here: https://faucet-beta-2.fuel.network/.
📃 GraphQL endpoint - The Fuel Core node uses GraphQL instead of JSON RPC. A playground for the public GraphQL endpoint for beta-1 is available at https://node-beta-2.fuel.network/playground.
🔍 Block explorer - A block explorer (still heavily in development) is available at https://fuellabs.github.io/block-explorer-v2/. Be sure to select
beta-2 from the dropdown on the top right.

Messages intended for contracts use a pre-defined predicate as the message recipient. This predicate allows anyone to relay the message to the target contract and only the target contract. Once the contract receives the message it can see who originated it along with any special message payload and processes it accordingly. Since anyone can relay the message using this predicate it opens up possibilities for automated message processing as a service.
The predicate root is
