💡Getting Started

Multisig IDL

Right now the best way to interact with the Cashmere multisig programmatically is directly through our IDL. Eventually we will provide an SDK which will make integrations easier.

The program is published on-chain at:

• Mainnet: AzHKmHjEoZ7JqiTUPgPVAZgtyNLwa3BTsRgffYxCVDD

• Testnet: AK6khFGW1guZxEJG3rd8SrEWW9Cdk13UQGD4f9hnn9AW
