This example shows how to receive data to your Solana program.

Example #1: Basic Oracle

The basic oracle will push data to your contract at some pre-defined schedule. You are responsible for storing this data yourself in some pre-defined struct.

Build Switchboard Function (Rust)

docker buildx build --pull --platform linux/amd64 \
    -f ./switchboard-functions/01_basic_oracle_function/Dockerfile \
    -t ${DOCKERHUB_ORGANIZATION}/solana-basic-oracle-function:latest \
    ./

# to publish

docker buildx build --pull --platform linux/amd64 \
