MsgStoreCode

Uploads new code to the blockchain and results in a new code ID, if successful. WASMByteCode is accepted as either uncompressed or gzipped binary data encoded as Base64.

Copy type MsgStoreCode struct { Sender sdk.AccAddress `json:"sender" yaml:"sender"` // WASMByteCode can be raw or gzip compressed WASMByteCode core.Base64Bytes `json:"wasm_byte_code" yaml:"wasm_byte_code"` }

MsgInstantiateContract

Creates a new instance of a smart contract. Initial configuration is provided in the InitMsg, which is a JSON message encoded in Base64. If Migratable is set to true, the owner of the contract is permitted to reset the contract's code ID to a new one.

Copy type MsgInstantiateContract struct { // Sender is an sender address Sender string `protobuf:"bytes,1,opt,name=sender,proto3" json:"sender,omitempty" yaml:"sender"` // Admin is an optional admin address who can migrate the contract Admin string `protobuf:"bytes,2,opt,name=admin,proto3" json:"admin,omitempty" yaml:"admin"` // CodeID is the reference to the stored WASM code CodeID uint64 `protobuf:"varint,3,opt,name=code_id,json=codeId,proto3" json:"code_id,omitempty" yaml:"code_id"` // InitMsg json encoded message to be passed to the contract on instantiation InitMsg encoding_json.RawMessage `protobuf:"bytes,4,opt,name=init_msg,json=initMsg,proto3,casttype=encoding/json.RawMessage" json:"init_msg,omitempty" yaml:"init_msg"` // InitCoins that are transferred to the contract on execution InitCoins github_com_cosmos_cosmos_sdk_types.Coins `protobuf:"bytes,5,rep,name=init_coins,json=initCoins,proto3,castrepeated=github.com/cosmos/cosmos-sdk/types.Coins" json:"init_coins" yaml:"init_coins"` }

MsgExecuteContract

Invokes a function defined within the smart contract. Function and parameters are encoded in ExecuteMsg, which is a JSON message encoded in Base64.

Copy type MsgExecuteContract struct { Sender sdk.AccAddress `json:"sender" yaml:"sender"` Contract sdk.AccAddress `json:"contract" yaml:"contract"` ExecuteMsg core.Base64Bytes `json:"execute_msg" yaml:"execute_msg"` Coins sdk.Coins `json:"coins" yaml:"coins"` }

MsgMigrateContract

Can be issued by the owner of a migratable smart contract to reset its code ID to another one. MigrateMsg is a JSON message encoded in Base64.

Copy type MsgMigrateContract struct { Owner sdk.AccAddress `json:"owner" yaml:"owner"` Contract sdk.AccAddress `json:"contract" yaml:"contract"` NewCodeID uint64 `json:"new_code_id" yaml:"new_code_id"` MigrateMsg core.Base64Bytes `json:"migrate_msg" yaml:"migrate_msg"` }

MsgUpdateContractOwner

Can be issued by the smart contract's owner to transfer ownership.

Copy type MsgUpdateContractOwner struct { Owner sdk.AccAddress `json:"owner" yaml:"owner"` NewOwner sdk.AccAddress `json:"new_owner" yaml:"new_owner"` Contract sdk.AccAddress `json:"contract" yaml:"contract"` }
