Deploy tools

In order to deploy or edit an oracle script, either our online IDE: Band Builder or our SDK's pyband and bandchain.js can be used.

Messages

Deploy message

In order to deploy an oracle script, we need to create MsgCreateOracleScript message and broadcast the message to BandChain.

MsgCreateOracleScript contains 7 parameters:

Parameter	Type	Description
Name	string	The name of the oracle script to be deployed
Description	string	A description of the oracle script
Schema	bytes	The oracle script's OBI schema
Source Code URL	string	An optional absolute URI to the oracle script's source code
Code	string	The oracle script's WebAssembly binary code. Can be raw or gzip compressed
Owner	string	The address of owner for the oracle script to be deployed
Sender	string	The address of the message sender

Edit message

After an oracle script is deployed, its parameters can be updated if need be. To update an oracle script, we can broadcast a MsgEditOracleScript message to BandChain.

MsgEditOracleScript contains 8 parameter:

Parameter	Type	Description string
OracleScriptID	int64	The data source identifier
Name	string	The name of the oracle script to be deployed
Description	string	A description of the oracle script
Schema	bytes	The oracle script's OBI schema
Source Code URL	string	An optional absolute URI to the oracle script's source code
Code	string	The oracle script's WebAssembly binary code. Can be raw or gzip compressed
Owner	string	The address of owner for the oracle script to be deployed
Sender	string	The address of the message sender

where the following field can be set as ["do-not-modify] in their respective types if no changes are required from the current value:

• name: "[do-not-modify]"
• description: "[do-not-modify"]"
• schema: "[stringot-modify]"
• source_code_url: "[do-not-modify]"
• code: b"[do-not-modify]"

In order to broadcast these messages, our online IDE, Band Builder can be used to both write the data source and deploy it. Alternatively, our SDK's bandchain.js and pyband can also be used.

Examples on how to form a transaction to send messages on pyband can be found here and an example for bandchain.js can be found here.
