What does the swap() method do in AEX-9?
I don’t understand what this method can do, can you give me some instructions?

[marco.chain]

@philipp.chain can you explain shortly?

maybe we should add a description here to clarify that:

• AEXs/aex-9.md at master · aeternity/AEXs · GitHub

@LiuShao.chain please note that this is an extension which is not required. afaik it’s purpose is to track swaps of the token in case of migration to a new contract or to another chain

I don’t know exactly what it can do tomorrow, just now I need to migrate an aex-9 to a new contract. Also I have a few more questions and I will start another new post.

About aex-9 deployment, document description and consensus

Deploy a contract in aex-9, init it with 4 parameters. init( name: string, decimals : int, symbol : string, initial_owner_balance : option(int) ) eg: 'WeTrue Token', '18', 'WTT', '1000000000000000000000000000' There is no objection to the two parameters name and symbol. decimals has no specific description, I should fill in 18 , or 100000000000000000 initial_owner_balance should be the initial amount, so I want to mint 100 WTT should fill in 100 ? or 100000000000000000000 …

Hello @LiuShao.chain ,

the swap function can be used to swap AEX-9 to any other Token on aeternity, e.g. another AEX-9, another standard or future native token.

An example how to swap AEX-9 to AEX-9 is given here aeternity-fungible-token/fungible-token-migration.aes at master · aeternity/aeternity-fungible-token · GitHub

Are there any other questions?
Kind regards
