Forge SDK - Grpc Client

To develop applications on top of the forge, you shall pick up a SDK. Forge SDK is intended to make the interaction with the chain built by Forge as easy as possible. All SDK APIs are organized into the following categories:

  • chain APIs: provide the client wrapper for chain related gRPC
  • wallet APIs: provide the client wrapper for wallet related gRPC
  • state APIs: provide the client wrapper for state related gRPC
  • subscription APIs: provide the client wrapper for subscription related gRPC
  • transaction APIs: the gRPC for transaction is send_tx, this set of APIs provide helper functions to make building and sending a tx easy.
  • misc APIs: parsing configuration, initialize sdk and more.

For more information, please see: Forge SDK overview


Wallet package will help user create local account, verify signature, etc. Functions as follows:

Wallet APIs as follows:

  • create_default_wallet() -> Result<Wallet>
  • from_wallet_type(w_type: &WalletType) -> Result<Wallet>
  • from_pk(pk: &[u8], w_type: &WalletType) -> Result<Wallet>
  • from_sk(sk: &[u8], w_type: &WalletType) -> Result<Wallet>
  • verify(&self, message: &[u8], signature: &[u8]) -> Result<bool>
  • sign(&self, message: &[u8]) -> Result<Vec<u8>>
  • etc


Help you create/get connection with forge chain, then send messages to forge chain by the connection. Messages include GetInfo, SendTx, GetState, Subscribe/Unsubscribe, etc.

Connection Mod

Help you create/get connection with forge chain.


Help you build transaction objects, then send it to forge chain.

Example Example how to create a local wallet, declare the wallet on forge chain, check in to get some tokens, then transfer some tokens to other. Example repo. More Examples

  • 1.Set Cargo.toml
    forge_wallet = "^0.1.2"
    forge_grpc = "^0.1.3"
  • 2.Add connection with forge chain.
    let chain_address = "";
    let chain_name = "chain_1";
    connection::add_connection(chain_name, chain_address)?;
  • 3.Create two accounts: Alice, bob.
    // create two local wallets: Alice, Bob
    let alice = forge_wallet::Wallet::create_default_wallet()?;
    let bob = forge_wallet::Wallet::create_default_wallet()?;
    // declare Alice on forge chain
    let mut request = transaction::build_request::Request {
        wallet: alice.clone(),
        forge_name: Some(chain_name.to_string()),
    let mut declare = transaction::build_itx::Declare {
        moniker: Some(String::from("alice")),
    forge_grpc::declare(&request, &declare)?;
    // declare Bob on forge chain
    request.wallet = bob.clone();
    declare.moniker = Some(String::from("bob_01"));
    forge_grpc::declare(&request, &declare)?;
  • 4.Alice checkin to get some tokens.
    request.wallet = alice.clone();
  • 5.Alice transfer 1.0 token to bob.
    let decimal = connection::get_connection(Some(chain_name.to_string()))
        .get_decimal() as usize;
    let transfer_itx = transaction::build_itx::Transfer {
        to: Some(bob.address.to_owned()),
        value: Some(forge_grpc::BigUint::from_string("1", decimal)?),
    forge_grpc::transfer(&request, &transfer_itx)?;
  • 6.Alice, bob check balance.
    // sleep 5s to wait transfer transaction stable.
    let resp = forge_grpc::get_account_state(
        &vec![alice.address, bob.address],
        "alice balance: {:#?}, bob balance: {:#?}",
