Launch in 3 easy steps


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";
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);
11     // Craft your transaction payload
12     const to = "0xMyOracleAddress";
13     const iface = new Interface(["function updatePrice(uint256)"]);
14     const data = iface.encodeFunctionData("updatePrice", [price]);
16     // Return execution call data
17    return { canExec: true, callData: [{ to, data }] };
18  });

Beefy Finance

Power vault harvesting and swapping tokens

“Gelato's Web3 Functions enable our smart contracts to become smarter by combining the power of automation and the ability to access external data. With Web3 Functions we can create more powerful products and also eliminate tedious operational tasks.”- Weso, Lead Developer & Head of Strategic Partnerships at Beefy


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


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.
