Compile PyTEAL sources,

C:\src\PriceCasterService>python teal\wormhole\pyteal\vaa-processor.py vaap.teal vaap-clear.teal
VAA Processor Program, (c) 2021-22 Randlabs Inc.
Compiling approval program...
Written to vaap.teal
Compiling clear state program...
Written to vaap-clear.teal

Copy compiled teal files to Sandbox (optional):

./sandbox copyTo /mnt/c/src/PriceCasterService/vaap.teal

Now copying /mnt/c/src/PriceCasterService/vaap.teal to Algod container in /opt/data//mnt/c/src/PriceCasterService/vaap.teal
./sandbox copyTo /mnt/c/src/PriceCasterService/vaap-clear.teal

Now copying /mnt/c/src/PriceCasterService/vaap-clear.teal to Algod container in /opt/data//mnt/c/src/PriceCasterService/vaap-clear.teal

  • Make sure to clear previously created VAA Processor Apps, example:
goal account  info -a OPDM7ACAW64Q4VBWAL77Z5SHSJVZZ44V3BAN7W44U43SUXEOUENZMZYOQU
Created Assets:
        <none>

Created Apps:
        ID 45231352, global state used 2/2 uints, 20/20 byte slices
Opted In Apps:
        ID 14713804, local state used 1/3 uints, 1/2 byte slices
		
		
goal app delete --app-id 45231352 --from OPDM7ACAW64Q4VBWAL77Z5SHSJVZZ44V3BAN7W44U43SUXEOUENZMZYOQU -o delete.txn
algokey -t delete.txn -o delete.stxn sign  -m $OWNER_MNEMO
goal clerk rawsend -f delete.sxtn
  • Deploy and bootstrap the VAA Processor contract.
 goal app create --creator "$OWNER_ADDR" --global-ints 4 --global-byteslices 20 --local-byteslices 0 --local-ints 0 --approval-prog vaap.teal --clear-prog vaap-clear.teal  --app-arg "b64:$GKEYSBASE64" --app-arg 'int:0' --app-arg 'int:0' -o create.txn
 algokey -t create.txn -o create.stxn sign  -m "$OWNER_MNEMO" && goal clerk rawsend -f create.stxn

Check the deployed application ID according to the final TX ID.

  • Compile the stateless logic with the VAA Processor ID, for example:
python teal\wormhole\pyteal\vaa-verify.py 45504480 vaaverify.teal

goal clerk compile vaaverify.teal
vaaverify.teal: 4H2VD6GY4L7HEOVTZBKGTO6EYFASYFOWN34ONR5HIFEE2JIJ2M5GK26SXI
  • Set the stateless program hash with the "setvphash" appcall:
goal app call --app-id 45504480 --from "$OWNER_ADDR" --app-arg "str:setvphash" --app-arg "addr:4H2VD6GY4L7HEOVTZBKGTO6EYFASYFOWN34ONR5HIFEE2JIJ2M5GK26SXI" -o setvphash.txn 
algokey -t setvphash.txn -o setvphash.stxn sign  -m "$OWNER_MNEMO" && goal clerk rawsend -f setvphash.stxn
  • To verify a sample VAA, you can use the testing library using Nodejs as follows:

Since there are three signers, VAA can be verified in a group transaction with just one step.

Stateless logic accepts signature subset as argument (encoded in base64).
