+# TSS Service
+
+Threshold signature service provides the processing and signing of the deposited token transfers to another chains based on the threshold signature scheme (TSS).
+It works as a decentralized solution connected to the Cosmos [Bridge Core](https://github.com/hyle-team/bridgeless-core) module to process and accumulate the cross-chain transfers.
+
+The TSS network requires a several parties launched by different validators.
+In a cooperation with each other, they will process the incoming deposits and withdraw user funds to the destination chain.
+
+Fore more information check the [`TSS Overview`](./docs/01_overview.md).
+
+## Becoming a part of TSS network
+Currently, to become a TSS network party, you should follow the next steps:
+- be a validator of the Cosmos [Bridge Network](https://github.com/hyle-team/bridgeless-core);
+- run the full nodes of the supported networks (e.g. Ethereum, Bitcoin, Zano etc.);

The last segment of the URL's path must represent\nthe fully qualified name of the type (as in\n`path/google.protobuf.Duration`). The name should be in a canonical form\n(e.g., leading \".\" is not accepted).\n\nIn practice, teams usually precompile into the binary all types that they\nexpect it to use in the context of Any. However, for URLs which use the\nscheme `http`, `https`, or no scheme, one can optionally set up a type\nserver that maps type URLs to message definitions as follows:\n\n* If no scheme is provided, `https` is assumed.\n* An HTTP GET on the URL must yield a [google.protobuf.Type][]\n  value in binary format, or produce an error.\n* Applications are allowed to cache lookup results based on the\n  URL, or have them precompiled into a binary to avoid any\n  lookup. Therefore, binary compatibility needs to be preserved\n  on changes to types. (Use versioned type names to manage\n  breaking changes.)\n\nNote: this functionality is not currently available in the official\nprotobuf release, and it is not used for type URLs beginning with\ntype.googleapis.com. As of May 2023, there are no widely used type server\nimplementations and no plans to implement one.\n\nSchemes other than `http`, `https` (or the empty scheme) might be\nused with implementation specific semantics."

Example:\n\n    package google.profile;\n    message Person {\n      string first_name = 1;\n      string last_name = 2;\n    }\n\n    {\n      \"@type\": \"type.googleapis.com/google.profile.Person\",\n      \"firstName\": \u003cstring\u003e,\n      \"lastName\": \u003cstring\u003e\n    }\n\nIf the embedded message type is well-known and has a custom JSON\nrepresentation, that representation will be embedded adding a field\n`value` which holds the custom JSON in addition to the `@type`\nfield. Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }"
