Supply Control Contract Interface

Supply Control Contract functions

Interfaces for interacting with the ASM Supply Control Contract functions using:

• The aut command-line RPC client to submit calls to inspect state and state-affecting transactions.

Protocol contract calls

Examples for calling functions from aut use the setup described in the How to Submit a transaction from Autonity Utility Tool (aut).

Usage and Examples illustrate using the Supply Control Contract’s generated ABI and the aut tool’s contract command to call the Supply Control Contract address 0x47c5e40890bcE4a473A49D7501808b9633F29782. See aut contract call --help.

Usage and Examples assume the path to the ABI file has been set in aut’s configuration file .autrc. The SupplyControl.abi file is generated when building the client from source and can be found in your autonity installation directory at ./params/generated/SupplyControl.abi. Alternatively, you can generate the ABI using the abigen cmd utility if you built from source (See Install Autonity, Build from source code).
