Gelato Relay Safe Transactions

This project demonstrates how to sponsor and execute transactions on a Safe using Gelato's Relay and 1Balance features. It supports:

• Sponsoring transactions using Gelato 1Balance.
• Executing transactions with the native token (syncFee).
• Executing transactions with ERC20 tokens (syncFee).

Prerequisites

Before running any scripts, ensure you have:

1. Node.js and Yarn: Installed and configured.
2. Hardhat: Installed in the project.
3. Environment Variables: Create a .env file with the following keys:
   • RPC_URL_KEY: RPC URL for Base Sepolia.
   • GELATO_PK: Private key for the Safe owner (1/1 signer).
   • GELATO_RELAY_API_KEY: API key for Gelato 1Balance.

Example .env file:

RPC_URL_KEY=<Your_Base_Sepolia_RPC_URL>
GELATO_PK=<Your_Private_Key>
GELATO_RELAY_API_KEY=<Your_Gelato_1Balance_API_Key>

Scripts

1. Safe with Gelato 1Balance

Run this script to sponsor a transaction to the counter contract using Gelato 1Balance.

yarn safe-1balance

File: ./relay-safe-scripts/1balance/safe-1balance.ts

2. Safe with syncFee (Native Token)

Run this script to execute a transaction using the native token (ETH) for fees.

yarn safe-syncFee-native

File: ./relay-safe-scripts/syncFee/safe-signer.ts

3. Safe with syncFee (ERC20 Token)

Run this script to execute a transaction using an ERC20 token (WETH) for fees.

yarn safe-syncFee-erc20

File: ./relay-safe-scripts/syncFee/safe-signer-weth.ts

Counter Contract

The counter contract is deployed on Base Sepolia at:

Contract Address: 0x20CDE68D6512B9080B5b6c5e46A8e96031126F3A

Contract Functionality

• increment: Increments the counter.

Safe Details

• Safe Address: 0x5E417f9d1dBbE6916fF7Be8A129A8b8A0B262609
• Threshold: 1/1 signer.

How to Track Transactions

After running a script, you will get a Gelato Task ID. Use this Task ID to monitor the transaction status on Gelato Relay:

Troubleshooting

1. Missing Environment Variables: Ensure your .env file is correctly configured with all necessary keys.

2. Transaction Reverts:

   • Verify that the Safe has enough funds or that the ERC20 token (e.g., WETH) is approved for use.
   • Check the contract deployment address and ABI.

3. API Key Issues:

   • Ensure your Gelato 1Balance API key is active and has sufficient funds deposited.

Additional Notes

• This repository uses Hardhat for development and deployment.
• The project interacts with the Gelato Relay, Safe, and a Counter contract on Base Sepolia.
• Scripts are modular and can be extended to other chains or contracts.
