NEAR Indexer 和 2FA 安全钱包交易

Question

在 Near，受 2FA 保护的钱包签署的交易以特殊方式（合同确认）完成，与常规交易不同。签名者和接收者 id 相同的钱包。样本交易： https://explorer.near.org/transactions/9uPvkdmcL4iNnWrHXZocf7NLAJUUVa4zSMrtFtJhrjcY

如何正确使用它们，在 Indexer 中哪里可以找到它们？如何正确获取数据，用户签什么合同，签什么方式？

Answer 1

此处为 Explorer 核心贡献者和维护者的 NEAR 索引器。

查看您在问题中提供的交易 https://explorer.near.org/transactions/9uPvkdmcL4iNnWrHXZocf7NLAJUUVa4zSMrtFtJhrjcY 它是方法 confirm

的 FUNCTION CALL

我相信您担心的是，您无法通过使用散列查询 transactions table 在 public NEAR Indexer for Explorer database 中看到交易结果。

并且说 2FA 交易“不像常规交易”是指涉及 cross-contract 调用的性质。

了解正在发生的事情的方法如下

首先，让我们查找您的初始交易及其转换后的收据 ID。

SELECT transaction_hash, converted_into_receipt_id FROM transactions WHERE transaction_hash = '9uPvkdmcL4iNnWrHXZocf7NLAJUUVa4zSMrtFtJhrjcY';

               transaction_hash               |          converted_into_receipt_id
----------------------------------------------+----------------------------------------------
 9uPvkdmcL4iNnWrHXZocf7NLAJUUVa4zSMrtFtJhrjcY | FP5UmXxdDBBicGkzgXXdhS28hxgBWVByFcqbwh25qHzN

根据您发送的这笔交易是对某些 ft_transfer 调用的确认，我们预计会对 gems.l2e.near 合约进行跨合约调用。

我们要查找执行收据id后产生的所有收据FP5UmXxdDBBicGkzgXXdhS28hxgBWVByFcqbwh25qHzN（我们在步骤1中找到了）

搜索在初始收据执行期间创建的所有收据

SELECT produced_receipt_id FROM execution_outcome_receipts WHERE executed_receipt_id = 'FP5UmXxdDBBicGkzgXXdhS28hxgBWVByFcqbwh25qHzN';
             produced_receipt_id

 3mtnLaGFYpXXzZ4H9vYczSXz9JbdS7XueSobDjQDAYb3
(2 rows)

所以我们还有另外两张收据，但我们实际上并不知道它们包含什么操作。让我们一探究竟。

SELECT receipt_id, action_kind, receipt_predecessor_account_id, receipt_receiver_account_id, args FROM action_receipt_actions WHERE receipt_id IN ('9zem8CxJvdTHKkZKCc1pFhg4Ky4st6TBrQmE19gv4sAU', '3mtnLaGFYpXXzZ4H9vYczSXz9JbdS7XueSobDjQDAYb3');
                  receipt_id                  |  action_kind  | receipt_predecessor_account_id | receipt_receiver_account_id |                                                                                                               args
----------------------------------------------+---------------+--------------------------------+-----------------------------+-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
 3mtnLaGFYpXXzZ4H9vYczSXz9JbdS7XueSobDjQDAYb3 | TRANSFER      | system                         | shishkerin.near             | {"deposit": "12306467158537048105440"}
 9zem8CxJvdTHKkZKCc1pFhg4Ky4st6TBrQmE19gv4sAU | FUNCTION_CALL | shishkerin.near                | gems.l2e.near               | {"gas": 220000000000000, "deposit": "1", "args_json": {"amount": "2970000", "receiver_id": "hot1.l2e.near"}, "args_base64": "eyJyZWNlaXZlcl9pZCI6ImhvdDEubDJlLm5lYXIiLCJhbW91bnQiOiIyOTcwMDAwIn0=", "method_name": "ft_transfer"}
(2 rows)

这里我们可以看到 Receipt 9zem8CxJvdTHKkZKCc1pFhg4Ky4st6TBrQmE19gv4sAU 实际上是由 shishkerin.near

签署的 FUNCTION_CALL to gems.l2e.near

我们也可以查看args，发现调用的方法是ft_transfer，参数是{"amount": "2970000", "receiver_id": "hot1.l2e.near"}

（另一张收据 3mtnLaGFYpXXzZ4H9vYczSXz9JbdS7XueSobDjQDAYb3 是由 system 签署的转账，基本上是 cash-back 附加气体）

为了理智起见，我们想知道收据的执行状态

SELECT receipt_id, status FROM execution_outcomes WHERE receipt_id = '9zem8CxJvdTHKkZKCc1pFhg4Ky4st6TBrQmE19gv4sAU';
                  receipt_id                  |    status
----------------------------------------------+---------------
 9zem8CxJvdTHKkZKCc1pFhg4Ky4st6TBrQmE19gv4sAU | SUCCESS_VALUE

希望这能回答您的问题。

除了@khorolets 已经提到的内容之外，receipts table 有 originated_from_transaction_hash 列可以帮助您获取归因于交易的所有收据：

SELECT * FROM receipts WHERE originated_from_transaction_hash = '9uPvkdmcL4iNnWrHXZocf7NLAJUUVa4zSMrtFtJhrjcY';

                  receipt_id                  |            included_in_block_hash            |            included_in_chunk_hash            | index_in_chunk | included_in_block_timestamp | predecessor_account_id | receiver_account_id | receipt_kind |       originated_from_transaction_hash
