How do we determine the tx type

The transaction service returns a list of transactions with certain attributes. How do we determine what kind of tx a certain transaction is? Here is a list of types we need to distinguish between.

I numbered them from 1.1.1 "Historic Safe to Safe ETH Transfer" to 2.3.1 which is a "Queued Custom Transaction".

We also need instructions on how to extract the values we need to display (according to Attributes in transaction list)

1. History

1.1. Transfers

Type	From ->	To	in/out	Currency
1	Safe	Safe	in/out	ETH
2	EOA	Safe	in	ETH
3	Safe	EOA	out	ETH
4	Safe	Safe	in/out	ERC20
5	EOA	Safe	in	ERC20
6	Safe	EOA	out	ERC20
7	Safe	Safe	in/out	ERC721
8	EOA	Safe	in	ERC721
9	Safe	EOA	out	ERC721

1.2. Settings Change

Type	Settings change
1	Add owner
2	Remove owner
3	Replace owner
4	Change Threshold
5	Change Mastercopy
6	Change Fallback Manager (Safes with version > 1.1.0)

1.3. Custom transactions

Type	Type Name
1	Custom transaction

2. Queued

A queued transaction is one such that its nonce is greater than that of the safe it corresponds to. As opposed to history transactions, which have a nonce smaller of that of the safe to which they correspond.

2.0. For any queued transaction we need to detect number of confirmation & rejections

2.1. Transfers

Type	From ->	To	in/out	Currency
1	Safe	Safe	in/out	ETH
2	EOA	Safe	in	ETH
3	Safe	EOA	out	ETH
4	Safe	Safe	in/out	ERC20
5	EOA	Safe	in	ERC20
6	Safe	EOA	out	ERC20
7	Safe	Safe	in/out	ERC721
8	EOA	Safe	in	ERC721
9	Safe	EOA	out	ERC721

2.2. Settings Change

Type	Settings change
1	Add owner
2	Remove owner
3	Replace owner
4	Change Threshold
5	Change Mastercopy
6	Change Fallback Manager (Safes with version > 1.1.0)

2.3. Custom transactions

Type	Type Name
1	Custom transaction

Special cases

• What do we do with a otherwise simple transfer that contains a data section? Is this always a custom transaction?

Solution

Please fill in the blanks below If two types are very similar to detect, feel free to merge them here

Regarding:

1.1.1 Historic Safe to Safe ETH transfer

(Please add instructions on how to detect this type of transfer here)

1.1.2 Historic EOA to Safe ETH transfer

• data must be empty
• to field needs to be the current safe address

1.1.3 Historic Safe to EOA ETH transfer

(Please add instructions on how to detect this type of transfer here) [...]
