Forge SDK

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

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_address(addr: &str) -> Result<Wallet>
• from_pk(pk: &[u8], w_type: &WalletType) -> Result<Wallet>
• from_sk(sk: &[u8], w_type: &WalletType) -> Result<Wallet>
• from_json(j: Value) -> Result<Wallet>
• to_json(&self) -> Result<Value>
• verify(&self, message: &[u8], signature: &[u8]) -> Result<bool>
• hash(&self, message: &[u8]) -> Result<Vec<u8>>
• sign(&self, message: &[u8]) -> Result<Vec<u8>>
• format_wallet(&mut self) -> Result<()>
• is_valid(wallet: &Wallet) -> bool

Example

Create two local wallets by create_default_wallet, which types are Account, Sha3, Ed25519 ```rust let alice = Wallet::createdefaultwallet()?; let bob = Wallet::createdefaultwallet()?;

```

GRPC

Help user create/get connection with forge chain, and communicate with forge chain by the connection.

Connection

• create connection: if start a forge chain with 127.0.0.1:28210, then create a connection and set alias name forge_chain_a with the forge chain as follows: rust let clients = connection::add_connection("forge_chain_a", "127.0.0.1:28210")?;

• get connection: get the connection created above in two ways: rust // get the conn by alias name `forge_chain_a` let conn = connection::get_connection(Some(String::from("forge_chain_a")))?; rust // get the first connection. let conn = connection::get_connection(None)?;
