Running local environment

Examples uses neon-devnet by default but you can also run your own setup locally for testing and experiments. Install latest docker and docker-compose. Make sure you have the latest version of docker-compose installed. It's v2.6.1 at the time of this update. To install v2.6.1, first remove existing installation of docker-compose:

sudo apt remove docker-compose

then install v2.6.1 wiht the following commands:

sudo curl -L "https://github.com/docker/compose/releases/download/v2.6.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

Then check the version to make sure it is the right one:

docker-compose --version   

you shoud see

Docker Compose version v2.6.1

NOTE local setup is only available on Linux OS-es. Just run from this directory:

docker-compose up -d

All APIs will be available at your localhost by addresses:

• solana http://localhost:8899
• faucet http://localhost:3333
• web3 proxy (Eth API) - http://localhost:9090/solana

Airdropping in local environment

Just execute from this directory:

./drop_neons.sh <target-eth-address>

NOTE Make sure you have curl installed in your system
