Registering in Almanac Contract


The Almanac ↗️ contract requires agents to register using their Agent Address and pay a fee for registration to be found by other agents on the network.


  1. First of all, create a Python script and name it by running: touch

  2. Then, import the Agent class from the uagents library to create our agent, and the fund_agent_if_low class from the uagents.setup module. This function will check if you have enough tokens to register in the Almanac contract, if not it will add testnet tokens to your Fetch Network address. Then, create an agent, alice, providing name, port, seed, and endpoint:
from uagents.setup import fund_agent_if_low
from uagents import Agent, Context, Protocol
agent = Agent(
    seed="alice secret phrase",
async def hi(ctx: Context):"Hello")

There's a few things happening in this script; we initialize Alice with an endpoint. An endpoint is the address in which other agents can send messages to where Alice will be listening. As highlighted in Registration and Endpoints Weighting ↗️, agents can communicate by querying the Almanac and retrieving an endpoint from the recipient agent. Therefore, we need to specify the service endpoints when defining our agents.

We also have to define This .run() function runs the agent, but more importantly this registers the agent to the Almanac when code is initialized.

Once you run your script, your agent will start the registration process automatically, the balance of the agent's wallet will be checked and funded if needed. Finally, it will try to register on the Almanac contract. Then, we will be ready to start to a remote communication with other agents registered within the Almanac contract.
