You can create transactions that execute smart contracts on any EVM compatible blockchain. The contract deployment is processed as a standard EVM raw transaction, and subject to policy governance and MPC signing.
Before creating a raw transaction, create a transaction rule for it. Typically, you'll use an EVM contract call, or Any. For more details, see Create EVM contract call rule.
To execute a smart contract, click Transfer on the left navigation menu, and then Raw Transaction.
