A system and method of a smart contract and distributed ledger platform with blockchain custody service includes a blockchain service circuit structured to interface with a distributed ledger; a data collection circuit structured to receive data related to items of collateral or data related to environments of the items of collateral; a valuation circuit structured to determine a value for each of the plurality of items of collateral based on a valuation model and the received data; and a smart contract circuit structured to interpret a smart lending contract for a loan, and to modify the smart lending contract by assigning, based on the determined value for each of the items of collateral, at least a portion of the items of collateral as security for the loan such that the determined value of the items of collateral is sufficient to provide security for the loan.

Implementations of the present specification describe a computer-implemented method, medium, and system. In one computer-implemented method, a contract creating request from a requesting user is received by a blockchain node of a blockchain network, where the contract creating request includes creation information of a target electronic contract to be created. A first smart contract is deployed for managing the target electronic contract in a blockchain based on the creation information. The target electronic contract is created according to the creation information and based on the first smart contract. In response to receiving a contract signing request from a signatory user of the target electronic contract, the target electronic contract is signed based on the first smart contract and a second smart contract corresponding to the signatory user, where the second smart contract is a pre-deployed smart contract for managing information associated with the signatory user.
