Basic example to connect to snowsight mempool streaming service in Rust

snowsight-rs

Basic Rust example of a client for snowsight Avalanche mempool streaming service. This uses tokio-tungstenite for the websocket, ethers-rs and cast to interact with the chain and chacha20poly1305 for private key encryption.

This contains examples for:

• Connecting to the websocket and receiving transactions
• Paying the snowsight fee for a given tier
• Using the transaction propagator

This could be used as a basis for a bot, although private key management should be improved.

Running the code

You should change the NONCE constant at line 14 in main.rs before use.

You can choose to include the line to pay the fee or not (line 35 in main.rs). Paying for the trial tier (0) costs a couple cents as of writing this.

You can now compile the code, during compilation keep reading.

Set the env var BOT_PWD with a 32 chars long password to encrypt and decrypt the private key.

Set the env var RPC_URL to an Avalanche mainnet RPC.

You can then run :

snowsight-rs <private-key>

Your private key will be encrypted and stored in the home directory for later use.

Then run the code to see the transactions stream.
