State Transition

This document describes the state transition operations pertaining to:

• Create namespace

• Delete namespace

• Update namespace

• Update namespace roles

• Revoke namespace roles

• Claim Voucher

• Update params

Create Namespace

Namespaces can be created for implementing different roles and actions.

message MsgCreateNamespace {
  option (cosmos.msg.v1.signer) = "sender";
  string sender = 1 [ (gogoproto.moretags) = "yaml:\"sender\"" ];

  Namespace namespace = 2 [ (gogoproto.nullable) = false ];
}

// Namespace defines a permissions namespace
message Namespace {
  string denom = 1; // tokenfactory denom to which this namespace applies to
  string wasm_hook =
      2; // address of smart contract to apply code-based restrictions

  bool mints_paused = 3;
  bool sends_paused = 4;
  bool burns_paused = 5;

  repeated Role role_permissions = 6; // permissions for each role

  repeated AddressRoles address_roles = 7;
}

message AddressRoles {
  string address = 1;
  repeated string roles = 2;
}

message Role {
  string role = 1;
  uint32 permissions = 2;
}

Steps

• Create a new denom

• Create a MsgCreateNamespace message with Denom, RolePermissions and AddressRoles.

• Validate the MsgCreateNamespace object.

• Send the create namespace message.

Delete Namespace

Deleting a namespace removes it and its associated roles and permissions.

message MsgDeleteNamespace {
  option (cosmos.msg.v1.signer) = "sender";
  string sender = 1 [ (gogoproto.moretags) = "yaml:\"sender\"" ];

  string namespace_denom = 2;
}

Steps

• Create a MsgDeleteNamespace message with the namespace denom NamespaceDenom to be deleted.

• Validate the MsgDeleteNamespace object.

• Send the delete namespace message.

Update Namespace

Updating a namespace allows modifying its associated roles and permissions.

message MsgUpdateNamespace {
  option (cosmos.msg.v1.signer) = "sender";
  string sender = 1 [ (gogoproto.moretags) = "yaml:\"sender\"" ];

  string namespace_denom =
      2; // namespace denom to which this updates are applied

  message MsgSetWasmHook { string new_value = 1; }
  MsgSetWasmHook wasm_hook =
      3; // address of smart contract to apply code-based restrictions

  message MsgSetMintsPaused { bool new_value = 1; }
  MsgSetMintsPaused mints_paused = 4;

  message MsgSetSendsPaused { bool new_value = 1; }
  MsgSetSendsPaused sends_paused = 5;

  message MsgSetBurnsPaused { bool new_value = 1; }
  MsgSetBurnsPaused burns_paused = 6;
}

Steps

• Create a MsgUpdateNamespace message with NamespaceDenom, and the new values for MintsPaused, BurnsPaused and SendsPaused.

• Validate the MsgUpdateNamespace object.

• Send the update namespace message.

Update Namespace Roles

Updating namespace roles allows modifying the roles and their permissions within a namespace.

message MsgUpdateNamespaceRoles {
  option (cosmos.msg.v1.signer) = "sender";
  string sender = 1 [ (gogoproto.moretags) = "yaml:\"sender\"" ];

  string namespace_denom =
      2; // namespace denom to which this updates are applied

  repeated Role role_permissions =
      3; // new role definitions or updated permissions for existing roles
  repeated AddressRoles address_roles =
      4; // new addresses to add or new roles for existing addresses to
  // overwrite current roles
}

Steps

• Create a MsgUpdateNamespaceRoles message with the NamespaceDenom, the new RolePermissions and AddressRoles.

• Validate the MsgUpdateNamespaceRoles object.

• Send the update namespace roles message.

Revoke Namespace Roles

Revoking namespace roles removes certain roles from an address within a namespace.

message MsgRevokeNamespaceRoles {
  option (cosmos.msg.v1.signer) = "sender";
  string sender = 1 [ (gogoproto.moretags) = "yaml:\"sender\"" ];

  string namespace_denom =
      2; // namespace denom to which this updates are applied
  repeated AddressRoles address_roles_to_revoke =
      3; // {"address" => array of roles to revoke from this address}
}

Steps

• Create a MsgRevokeNamespaceRoles message with the NamespaceDenom and AddressRolesToRevoke.

• Validate the MsgRevokeNamespaceRoles object.

• Send the revoke namespace roles message.

Claim Voucher

message MsgClaimVoucher {
  option (amino.name) = "permissions/MsgClaimVoucher";
  option (cosmos.msg.v1.signer) = "sender";
  string sender = 1 [ (gogoproto.moretags) = "yaml:\"sender\"" ];

  string denom = 2;
}

Update Params

message MsgUpdateParams {
  option (cosmos.msg.v1.signer) = "authority";

  // authority is the address of the governance account.
  string authority = 1 [ (cosmos_proto.scalar) = "cosmos.AddressString" ];

  // params defines the permissions parameters to update.
  //
  // NOTE: All parameters must be supplied.
  Params params = 2 [ (gogoproto.nullable) = false ];
}

message Params {
  option (gogoproto.equal) = true;

  uint64 wasm_hook_query_max_gas = 1;
}
