The Fuel toolchain is built on top of the Rust programming language. To install Rust, you can use the rustup tool.
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh To install the Fuel toolchain, you can use the fuelup-init script.
This will install forc, forc-client, forc-fmt, forc-lsp, forc-wallet as well as fuel-core in ~/.fuelup/bin.
curl https://install.fuel.network | shHaving problems? Visit the installation guide or post your question in our forum .
An API key from any RPC provider that supports the Sepolia network will work. Relayers will help listen to events from the Ethereum network. We recommend either Infura or Alchemy
The endpoints should look like the following:
https://sepolia.infura.io/v3/{YOUR_API_KEY}https://eth-sepolia.g.alchemy.com/v2/{YOUR_API_KEY}Note that using other network endpoints will result in the relayer failing to start.
Generate a new P2P key pairing by running the following command:
fuel-core-keygen new --key-type peering
{
"peer_id":"16Uiu2HAmEtVt2nZjzpXcAH7dkPcFDiL3z7haj6x78Tj659Ri8nrs",
"secret":"b0ab3227974e06d236d265bd1077bb0522d38ead16c4326a5dff2f30edf88496",
"type":"peering"
}
### Do not share or lose this private key! Press any key to complete. ###Make sure you save this somewhere safe so you don't need to generate a new key pair in the future.
To run a local node with persistence, you must configure a chainConfig.json file.
