Deploy Application Contract

Deploy the oracle contract that receives and verifies price feeds. The enclave registry is already deployed on-chain — when you publish the Demo package, it automatically links to the existing registry.

Configure Sui CLI

Make sure you're connected to the right network:

# Check current environment
sui client active-env

# Switch to testnet if needed
sui client switch --env testnet

Build and Publish

Navigate to the Demo contracts directory and publish:

cd contracts/Demo
sui move build
sui client publish

Save Object IDs

The publish transaction outputs several object IDs. You need to save three of them:

Object	Description
DEMO_PACKAGE_ID	The published package address
ORACLE_ID	Shared PriceOracle object
ADMIN_CAP_ID	Owned AdminCap capability for admin operations

Look for these in the transaction output.

tip

Save these IDs somewhere accessible - you'll need them for PCR configuration and price updates.

Export them as environment variables for convenience:

export DEMO_PACKAGE_ID=0x...
export ORACLE_ID=0x...
export ADMIN_CAP_ID=0x...

Update Expected PCRs

Configure the oracle with the PCR values of the enclave you trust:

# Get PCR values from the enclave attestation
oyster-cvm verify --enclave-ip $PUBLIC_IP

# Update the oracle's expected PCRs
sui client call \
    --package $DEMO_PACKAGE_ID \
    --module oyster_demo \
    --function update_expected_pcrs \
    --args $ORACLE_ID $ADMIN_CAP_ID 0x<PCR0> 0x<PCR1> 0x<PCR2> 0x<PCR16> \
    --gas-budget 10000000

This tells the contract which enclave configurations to trust when verifying price updates.
