Today, I found a tutorial to keep it so that if someone studies EOS/Vaulta/$A in the future, it may be used.
The EOS chain is quite complex, and the data documents are relatively scattered.
First of all, EOS is now called Vaulta, and the token is called $A, which everyone knows.
Amazingly, Vaulta now has two chains side by side:
One is the traditional virtual machine of EOS, which is the familiar free transfer model with RAM mechanism.
One is an EVM-compatible chain, using the Ethereum gas mechanism.
The two chains are crossed through an official gateway.
The cross-chain method is very distinctive, which is to transfer money directly to the gateway (eosio.evmin), and then note the memo address (0x1234...... 5678）。
What's even more amazing is that the token $EOS still exists today and can be swapped 1:1 with $A.
The role of the old $EOS is to be used cross-chain.
Presumably, since Vaulta had not changed its name when it launched EVM before, this cross-chain gateway can only cross $EOS.
So it created the most magical situation:
The token on Vaulta is A
The token on the Vaulta EVM is EOS
Although the two are 1:1 interchangeable 😂
In addition, a few details to note are:
First of all, it's not about transferring A to the gateway, it's about transferring EOS to the gateway.
How do I change my $EOS for $A?
It is also a transfer, which is achieved directly by transferring money to core.vaulta
In addition, the cross-chain fee is 0.1 EOS
So below 0.1 EOS will fail across chains, and it takes several attempts to succeed.
