0x00 Description

Aptos SDK impl in elixir!

See the using example in:

https://github.com/NonceGeek/move_sdk_ex_liveview_example

0x01 Implementation

  • Aptos
    • RPC Implementation
    • Read Resource
    • Send Transaction
    • Chain Interactor
    • Smart Contract Parser
    • Mutiple Code Generator

0x02 Preparation

Test Smart Contract Lists:

0x03 Installation

If available in Hex, the package can be installed by adding web3_aptos_ex to your list of dependencies in mix.exs:

def deps do
  [
    {:web3_aptos_ex, "~> 1.4.2"}
  ]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/web3_aptos_ex.

0x04 Aptos

Namespace: Web3AptosEx.Aptos

4.1 Create a Connect

import Web3AptosEx.Aptos

alias Web3AptosEx.Aptos

{:ok, client} = Aptos.RPC.connect("https://fullnode.testnet.aptoslabs.com/v1")

client

4.2 Create Account

Aptos using the Ed25519 Algorithm for the Account.

priv = Web3AptosEx.Crypto.generate_priv()
{:ok, account} = Aptos.Account.from_private_key(priv)
account
{:ok, res} = Aptos.get_faucet(client, account)
Process.sleep(5000)
{:ok, account_ol} = Aptos.load_account(client, account)
account_ol
# it will works if account is actived(has any APT)

4.3 Read Resource of Acct

4.3.1 Read the resources of the Acct

Aptos.RPC.get_resources(client, "0x3")

4.3.2 Read resource by resource_type

Web3AptosEx.Aptos.RPC.get_resource(client, "0x3", "0x1::account::Account")

4.3.2 Read the item in Table

💡 You could get handle in Explorer:

https://explorer.aptoslabs.com/account/0x2df41622c0c1baabaa73b2c24360d205e23e803959ebbcb0e5b80462165893ed/resources

Web3AptosEx.Aptos.RPC.get_table_item(
  client,
  "0xe30b2ff6a515aa04729522512d50147d5cdd52ee3741c26ff1b97306b0b2b148",
  "0x1::string::String",
  "0x65f4a0954aa6e68d2381ff98b7676df2fe57beee3ca37a4a8a57fa621c1db872::addr_info::AddrInfo",
  "0x73c7448760517E3E6e416b2c130E3c6dB2026A1d"
)

4.4 Send Tx

{:ok, f} = ~a"0x1::coin::transfer<CoinType>(address, u64)"
payload = Aptos.call_function(f, ["0x1::aptos_coin::AptosCoin"], [account_ol.address, 100])
Aptos.submit_txn_with_auto_acct_updating(client, account_ol, payload)

4.5 Smart Contract Code Parser

Parse the smart contract code, it is the basis for generating call-codes for mutiple langugage, and the embedding for the smart contract to vector dataset!

# TODO: make it run in livebook
payload = " module hello_blockchain::message {\n            use std::error;\n            use std::signer;\n            use std::string;\n            use aptos_framework::account;\n            use aptos_framework::event;\n\n        //:!:>resource\n            struct MessageHolder has key {\n                message: string::String,\n                message_change_events: event::EventHandle<MessageChangeEvent>,\n            }\n        //<:!:resource\n\n            struct MessageChangeEvent has drop, store {\n                from_message: string::String,\n                to_message: string::String,\n            }\n\n            /// There is no message present\n            const ENO_MESSAGE: u64 = 0;\n\n            #[view]\n            public fun get_message(addr: address): string::String acquires MessageHolder {\n                assert!(exists<MessageHolder>(addr), error::not_found(ENO_MESSAGE));\n                borrow_global<MessageHolder>(addr).message\n            }\n\n            public entry fun set_message(account: signer, message: string::String)\n            acquires MessageHolder {\n                let account_addr = signer::address_of(&account);\n                if (!exists<MessageHolder>(account_addr)) {\n                    move_to(&account, MessageHolder {\n                        message,\n                        message_change_events: account::new_event_handle<MessageChangeEvent>(&account),\n                    })\n                } else {\n                    let old_message_holder = borrow_global_mut<MessageHolder>(account_addr);\n                    let from_message = old_message_holder.message;\n                    event::emit_event(&mut old_message_holder.message_change_events, MessageChangeEvent {\n                        from_message,\n                        to_message: copy message,\n                    });\n                    old_message_holder.message = message;\n                }\n            }\n\n            #[test(account = @0x1)]\n            public entry fun sender_can_set_message(account: signer) acquires MessageHolder {\n                let addr = signer::address_of(&account);\n                aptos_framework::account::create_account_for_test(addr);\n                set_message(account,  string::utf8(b\"Hello, Blockchain\"));\n\n                assert!(\n                get_message(addr) == string::utf8(b\"Hello, Blockchain\"),\n                ENO_MESSAGE\n                );\n            }\n        }"
{:ok, tokens, _} = :smart_move_leex.string(String.to_charlist(payload))
:smart_move_yecc.parse(tokens)
