Sebastian Abondano	1867d16417	Add account#tokentx API endpoint ... Why: * For API users to be able to get a list of token transfer events by address. A contract address can also be given, in addition to an address. Optional params include: 'startblock', 'endblock', 'sort', 'page', and 'offset'. Example usage: ``` /api?module=account&action=tokentx&address={addressHash} ``` * Issue link: https://github.com/poanetwork/blockscout/issues/571 This change addresses the need by: * Adding `Explorer.Etherscan.list_token_transfers/3` to get token transfer data required from db. * Adding `tokentx/2` action to `API.RPC.AddressController` to handle `?module=account&action=tokentx&...` API requests. * Editing `API.RPC.AddressView` to render token transfer events as needed. * Deleting duplicate line in `Explorer.Chain.TokenTransfer`. This looks like a typo. * Other than adding tests for the new functions mentioned above, `optional_params/1` within `API.RPC.AddressController` was promoted to a public function and unit tests were added for it. * Adding docs for `account#tokentx` API endpoint. Documentation data lives in `BlockScoutWeb.Etherscan`.	6 years ago

Sebastian Abondano	493695c95a	Add API txlistinternal action for account module ... Why: * For users to be able to get a list of internal transactions for a given transaction hash (Etherscan-compatible). * Issue link: https://github.com/poanetwork/blockscout/issues/138 This change addresses the need by: * Adding `Explorer.Etherscan.list_internal_transactions/1` to fetch internal transactions data as needed to be Etherscan-compatible. * Adding `txlistinternal/2` action to `API.RPC.AddressController` * Adding `txlistinternal.json` `render/2` function head to `API.RPC.AddressView` to render internal transaction lists as needed. * Adding documentation for the new action. Documentation data lives in `BlockScoutWeb.Etherscan` * Making `where_transaction_has_multiple_internal_transactions/1` a public function and adding doc, spec, and two new tests for it. This was necessary to use it from `Explorer.Etherscan.list_internal_transactions/1`.	6 years ago

Sebastian Abondano	e4dcdc3e92	Add event logs API support ... Why: * For API users to be able to get event logs in an Etherscan-compatible way. * Issue link: https://github.com/poanetwork/blockscout/issues/138 This change addresses the need by: * Editing the router to add support for `/api?module=logs&action=getLogs...` calls. * Adding a new `API.RPC.LogsController` to handle log related requests. * Adding `API.RPC.LogsView` * Adding `Explorer.Etherscan.Logs` where we've added functions to help us fetch logs as required by the supported filter parameters. The `list_logs/1` function in this new module is exposed through the `Explorer.Etherscan` context. * Adding 'logs' module and 'getLogs' action to API docs.	6 years ago

Luke Imhoff	2f3af51741	Unified Explorer.Chain.import ... * Merge `Explorer.Chain.import_blocks` and `Explorer.Chain.import_internal_transactions` into `Explorer.Chain.import`. * Move body of `Explorer.Chain.import` and its private helper functions to `Explorer.Chain.Import` as an independent context that `Explorer.Chain` can use. `Explorer.Chain.Import` must be under `Explorer.Chain` because `Explorer.Chain.Import` still needs direct access to the `Explorer.Chain` schemas.	6 years ago
Luke Imhoff	c4133c1fb0	Validate Transacton from_address_hash as required ... It was marked null: false, but an optional parameter in Transaction.changeset, so could trigger a database not-null constraint violation.	6 years ago
Luke Imhoff	b96891ced2	Move import functions into Explorer.Chain.Import ... Context needs to stay under `Explorer.Chain` because `Explorer.Chain.*` schemas, which only respects the `Explorer.Chain` API boundard when `Import` stays below `Explorer.Chain`.	6 years ago

Sebastian Abondano	86de475385	Add optional params to account txlist API endpoint ... Why: * For users to be able to specify optional params when calling the API RPC account transactions (action=txlist) endpoint. Example usage: ``` /api?module=account&action=txlist \ &address=0xddbd2b932c763ba5b1b7ae3b362eac3e8d40121a \ &startblock=100&endblock=150&page=1&offset=10&sort=asc ``` * Issue link: https://github.com/poanetwork/poa-explorer/issues/138 This change addresses the need by: * Editing `Explorer.Etherscan.list_transactions/2` to support `order_by_direction`, `page_number`, `page_size`, `start_block`, and `end_block` options. * Editing `API.RPC.AddressController` to support 'sort', 'page', 'offset', 'startblock', and 'endblock' params. Mimics Etherscan's API. When the optional params are not provided we return a max of 10,000 transactions, order by block number in ascending order, and target all blocks.	6 years ago

Amanda Sposito	73856a72df	Add read only functions to 'SmartContract.Reader'	6 years ago
Lucas Narciso	537f090597	Create Explorer.SmartContract.Reader ... This new module is the main entry point for getting results of a smart contract function. It accepts a smart contract hash and a list of functions names and its arguments (when applicable) in order to execute those functions and return their results. Before actually making the call to the blockchain, the function name is encrypted and the arguments are encoded. The EthereumJSONRPC deals with this, encrypting the name of the function using the Keccak256 algorithm and encoding the arguments based on their type. The call to the blockchain is also made by EthereumJSONRPC. The result is then decoded - as it comes in the same type of encoding that has been sent - by the EthereumJSONRPC lib as well, and returned. The return is a list of results of calling the functions in the blockchain. Note that each function may return more than one result, so for each functions there is a list of results.	6 years ago

Sebastian Abondano	e8a9b63d7b	Add account transactions API RPC endpoint ... Why: * For users to be able to get the transactions for a given address hash. Support for optional parameters will be added in an upcoming PR. * Issue link: https://github.com/poanetwork/poa-explorer/issues/138 This change addresses the need by: * Adding `Explorer.Etherscan` context, where we want to keep etherscan-only logic within the Explorer app. This is because we want to mimic the way their RPC API works. The only function in this module for now is `list_transactions/1`, which gets all transactions for a given address hash. * Adding `txlist/2` action to `API.RPC.AddressController`, to handle account transactions requests. Example usage: ``` api?module=account&action=txlist \ &address=0xddbd2b932c763ba5b1b7ae3b362eac3e8d40121a ``` * Editing `API.RPC.AddressView` and `API.RPC.RPCView` to format responses for new API endpoint as required. * Editing `.credo.exs` to allow for `Hash.Address.t()` alias usage in `Explorer.Etherscan` without Credo complaining with: ``` Software Design ┃ ┃ [D] ↓ Nested modules could be aliased at the top of the invoking module. ┃ apps/explorer/lib/explorer/etherscan.ex:19:51 ```	6 years ago
