Concepts

The smart contract deployment process consists of two steps that are outlined below:

• Deploy: smart contract is initialized on the blockchain.
• Lock: smart contract is finalized and can't be modified further.

Deploy

User creates a new smart contract and posts it on chain. The provided WASM bincode will initialize all the database trees required by the smart contract. The contract state definition consinst of the current contract WASM bincode and its database opened trees.

The smart contract state definition can be updated, as long as its unlocked.

Smart Contract Status

• Unlocked: the smart contract state definition can be updated.
• Locked: the smart contract is finalized and no more changes are allowed.

Lock

User can finalize their smart contract state definition on chain, locking down the contract, preventing further state changes. This action is irreversible and the smart contract state definitions cannot be modified afterwards.
