How do I connect to a smart contract from a smart contract? Another way to call contracts from a smart contract is to use a mechanism like dependency injection. With this method, the caller can immediately enter the contract he wants to call and knows the signature type of the function, which also has the nice side effect, return values can be received.

Where are smart contracts stored?
Simply put, smart contracts are programs stored on a blockchain that run when pre-determined conditions are met. They are usually used to automate the implementation of the agreement so that all participants can be immediately assured of the outcome, without any intermediary or time loss.
Where is smart contract data stored? Smart contract data is stored in the ledger as part of the state of the smart contract bound by its address. When a new version of the smart contract is used it gets a new direction. Therefore, it cannot handle data that is incorporated into the previous version of the contract.
Are smart contracts stored in blocks?
A bytecode of a smart contract is issued in a transaction (which is mined in a block), and then stored in a cache of the network (usually Ethereum or Binance Smart Chain) associated with an address.

The current model is limited to one state change (transaction) per block per smart link.
Where are Ethereum smart contracts stored?
In Ethereum, smart contract code themselves are stored on a chain directly as a state. In Hyperledger Fabric and Corda, the other leading enterprise blockchain protocols, contract code are stored off-chain, a chain hash is used to represent the proposed version of the smart contract.

Storage test is where all contract data resides. Each Ethereum account has its own storage test. A 256-bit mash of the root node of the storage trie is stored as the storageRoot value in the global state trie (which we just discussed).
Where are smart contracts executed?
The smart contract is implemented through a blockchain network, and the contract code is repeated on many networked computers. This ensures that the contractual terms are facilitated and performed more transparently and securely.
Where are Ethereum smart contracts stored?
1) Where is the contract stored? Ethereum has contracts (called smart contracts) on the chain, ie. code is compiled into byte code and the resulting bytes are sent within a transaction to be continued into the Ethereum blockchain. This is done once when you use the smart contract.
Who executes smart contract?
Smart contracts are programs implemented by blockchain nodes independently, to record the state of the last program. “Digital currency behaves like a ‘normal’ currency because of the rules governing what someone can and can’t do to adjust the ledger (or transaction registry).
