====== A.1.2 Call Class ======
[[dido:public:s_cli:05_contents:03_prt:08_basic_dido_objects:start| Basic Ethereum Data Store]]

For transactions related to a contract, internal transactions (calls) are executed. Call table contains enriched data from "Contract" and "Token" table using contract ABI to e.g. decode the name of the contract method. Internal transaction type of contract-related transactions.

===== Probablity =====
[[dido:public:s_cli:05_contents:03_prt:08_basic_dido_objects:02_call:start| Return to Top]]

Currently these are set to 1 for all data that we can retrieve from the blockchain or verify via Etherscan. In case we’re able to find a matching contract in our database by comparing the byte code of a contract or find a similar contract on a different blockchain, this is reflected in the probability. The probabilities are then copied into the Event and Call tables to give an indication of how sure we are this is the right translation.
