This section defines the sdk.Msg concrete types that result in the state transitions defined on the previous section.
RegisterCoinProposal
A gov Content type to register a token pair from a Cosmos Coin. Governance users vote on this proposal and it automatically executes the custom handler for RegisterCoinProposal when the vote passes.
typeRegisterCoinProposalstruct {// title of the proposal Title string`protobuf:"bytes,1,opt,name=title,proto3" json:"title,omitempty"`// proposal description Description string`protobuf:"bytes,2,opt,name=description,proto3" json:"description,omitempty"`// token pair of Cosmos native denom and ERC20 token address Metadata types.Metadata`protobuf:"bytes,3,opt,name=metadata,proto3" json:"metadata"`}
The proposal content stateless validation fails if:
Title is invalid (length or char)
Description is invalid (length or char)
Metadata is invalid
Name and Symbol are not blank
Base and Display denominations are valid coin denominations
Base and Display denominations are present in the DenomUnit slice
Base denomination has exponent 0
Denomination units are sorted in ascending order
Denomination units not duplicated
RegisterERC20Proposal
A gov Content type to register a token pair from an ERC20 Token. Governance users vote on this proposal and it automatically executes the custom handler for RegisterERC20Proposal when the vote passes.
typeRegisterERC20Proposalstruct {// title of the proposal Title string`protobuf:"bytes,1,opt,name=title,proto3" json:"title,omitempty"`// proposal description Description string`protobuf:"bytes,2,opt,name=description,proto3" json:"description,omitempty"`// contract address of ERC20 token Erc20Address string`protobuf:"bytes,3,opt,name=erc20address,proto3" json:"erc20address,omitempty"`}
The proposal Content stateless validation fails if:
Title is invalid (length or char)
Description is invalid (length or char)
ERC20Address is invalid
MsgConvertCoin
A user broadcasts a MsgConvertCoin message to convert a Cosmos Coin to a ERC20 token.
typeMsgConvertCoinstruct {// Cosmos coin which denomination is registered on erc20 bridge.// The coin amount defines the total ERC20 tokens to convert. Coin types.Coin`protobuf:"bytes,1,opt,name=coin,proto3" json:"coin"`// recipient hex address to receive ERC20 token Receiver string`protobuf:"bytes,2,opt,name=receiver,proto3" json:"receiver,omitempty"`// cosmos bech32 address from the owner of the given ERC20 tokens Sender string`protobuf:"bytes,3,opt,name=sender,proto3" json:"sender,omitempty"`}
Message stateless validation fails if:
Coin is invalid (invalid denom or non-positive amount)
Receiver hex address is invalid
Sender bech32 address is invalid
MsgConvertERC20
A user broadcasts a MsgConvertERC20 message to convert a ERC20 token to a native Cosmos coin.
typeMsgConvertERC20struct {// ERC20 token contract address registered on erc20 bridge ContractAddress string `protobuf:"bytes,1,opt,name=contract_address,json=contractAddress,proto3" json:"contract_address,omitempty"`
// amount of ERC20 tokens to mint Amount github_com_cosmos_cosmos_sdk_types.Int `protobuf:"bytes,2,opt,name=amount,proto3,customtype=github.com/cosmos/cosmos-sdk/types.Int" json:"amount"`
// bech32 address to receive SDK coins. Receiver string`protobuf:"bytes,3,opt,name=receiver,proto3" json:"receiver,omitempty"`// sender hex address from the owner of the given ERC20 tokens Sender string`protobuf:"bytes,4,opt,name=sender,proto3" json:"sender,omitempty"`}
Message stateless validation fails if:
Contract address is invalid
Amount is not positive
Receiver bech32 address is invalid
Sender hex address is invalid
ToggleTokenConversionProposal
A gov Content type to toggle the internal conversion of a token pair.
typeToggleTokenConversionProposalstruct {// title of the proposal Title string`protobuf:"bytes,1,opt,name=title,proto3" json:"title,omitempty"`// proposal description Description string`protobuf:"bytes,2,opt,name=description,proto3" json:"description,omitempty"`// token identifier can be either the hex contract address of the ERC20 or the// Cosmos base denomination Token string`protobuf:"bytes,3,opt,name=token,proto3" json:"token,omitempty"`}
