Contract Wrappers

The contract wrappers provided by Nerman.js currently support basic event listening. You can interact with these events using the following functions on each wrapper.

constructor()

  • provider: string | ethers.JsonRpcProvider. Our wrappers can handle providers behind the scene, so you only need to provide a JSON RPC URL from your preferred provider (like Alchemy) to make them work. We also offer the ability to pass in your own provider, giving you flexibility when needed.
import * as nerman from "nerman";

const nouns = new nerman.Nouns("<JSON_RPC_URL>");

on()

Registers a listener function to the given event, triggering the function with the appropriate data whenever the event fires on the blockchain. Throws an error if the event is not supported.

  • eventName: string. The name of the event.
  • listener: Function. The listener function.
nouns.on("NounCreated", (data) => {
	console.log(data.id);
});

off()

Removes any assigned listeners from the event. Does nothing if there was no listener.

  • eventName: string. The event name.
nouns.off("NounCreated");

trigger()

Triggers the listener of the given event with the given data. Throws an error if there is no listener assigned.

  • eventName: string. The event name.
  • data: unknown. The event data.
nouns.trigger("NounCreated", {
	id: 420,
	seed: {
		background: 0,
		body: 0,
		accessory: 0,
		head: 0,
		glasses: 0
	}
});

Nouns Forks

Each fork has its own unique addresses for its treasury, token, auction, and logic contracts. These deployed contracts can be found in the Nouns Fork Deployer Contract events.

There do not appear to be any auction proxies at the moment, and there are no triggered auction events.
