Kernel
Introduction
The Andromeda Kernel acts as the core of the operating system.
The Kernel receives and handles packets from ADOs to be relayed to a specified recipient. The Kernel keeps track of the original sender of the message. It also verifies that the packet is sent by an Andromeda certified ADO before relaying the message.
The Kernel is also responsible for:
Relaying any IBC messages across any two chains that have an Andromeda Kernel deployed and a channel set up.
Keeping track of the other AMP ADOs such as the ADODB, VFS, and Economics.
All of our ADOs have an AMPReceive execute message to handle receiving packets from the Kernel.
The Kernels are set up by the Andromeda team on each chain. This means that as a regular user, you will not need to interact with this ADO yourself in most cases. This page serves as additional information on how it works for people that are interested into getting a deep understanding of our system.
The only only message that users will be calling is the Recover execute message that will recover IBC funds sent in case the IBC message fails.
InstantiateMsg
ExecuteMsg
AMPReceive
Receives an AMP packet from another ADO. The packet is received, unpacked and the messages are relayed to their intended destination.
Only an AMPPkt sent from one of the Andromeda ADOs is accepted.
Information about the AMPPkt
struct can be found here.
Send
Constructs an AMPPkt with a given AMPMsg and sends it to the recipient.
Create
Creates an ADO with the given type and message.
UpsertKeyAddress
Used to save the addresses of the AMP ADOs that the Kernel will be interacting with such as the ADODB, Economics, and VFS.
Only available to the owner of the Kernel.
AssignChannels
Assigns a given channel between the current chain and the specified target chain
. For a successfull channel to be set up, both the channel ids need to be specified.
Only available to the owner of the Kernel.
Calling this message again, will override any previously set channels.
Recover
Recovers sent IBC funds to the user in case an IBC message fails.
UpdateChainName
Update the name of the chain the kernel is deployed on. This name is initially specified at instantiation.
Only available to the owner of the Kernel ADO.
RegisterUserCrossChain
Used to register a VFS username cross-chain.
This message can only be called by the VFS.
Ownership
The set of ownerhsip messages. These messages are the same as the ones found in the ADO base section.
QueryMsg
KeyAddress
Queries the address of the specified key
.
Returns the address in a string.
VerifyAddress
Checks if the specified address
was created by an Andromeda ADO by checking and comparing the code_Id
of the address with the code_Ids stored in the ADODB.
Returns true if the address was created by an Andromeda ADO and false otherwise.
ChannelInfo
Gets the saved channel information such as channel ids for the specified chain.
ChannelInfoResponse
Recoveries
Gets any fund recoveries available for the specified address.
Returns a Vec<Coin> containing the recoverable funds.
ChainName
Returns the saved chain name specified at instantiation.
ChainNameResponse
The struct containing the chain name.
Version
Queries the version of the ADO.
VersionResponse
Owner
Queries the owner of the contract.
ContractOwnerResponse
Type
Queries the ADO type.
