Launch in 3 easy steps

1

Set your logic

Set your custom Web3 Function logic. Connect to APIs & tell Gelato when to execute

1  import { Web3Function } from "@gelatonetwork/web3-functions-sdk";
2  import { Interface } from "@ethersproject/abi";
3  import axios from "axios";
4
5  Web3Function.onRun(async () => {
6     // Call any off-chain apis
7     const apiUrl = "https://api.coingecko.com/api/v3/coins/ethereum";
8     const coin = await axios.get(apiUrl);
9     const price = Math.floor(coin.data.market_data.current_price.usd);
10
11     // Craft your transaction payload
12     const to = "0xMyOracleAddress";
13     const iface = new Interface(["function updatePrice(uint256)"]);
14     const data = iface.encodeFunctionData("updatePrice", [price]);
15
16     // Return execution call data
17    return { canExec: true, callData: [{ to, data }] };
18  });

Abracadabra

Most optimal routes for swaps, withdraws, & buybacks

“With Gelato Network's Web3 Functions, we automated our yield farming vault's compounding and staking reward buybacks on Abracadabra.money. This streamlined our process and made it easier and more reliable than running our own infrastructure, making it an indispensable tool for our yield farming and lending products.”- Abracadabra

Aavegotchi

The best possible price for $GHST token buybacks

Aavegotchi relies on Web3 Functions to perform regular buybacks of the $GHST token. By utilizing Paraswap’s external APIs, swaps are guaranteed the best possible price as the routing is handled automatically off-chain.
