Gelato Raas Account Abstraction with Safe

This starter helps to quick start developing on Gelato Raas with Safe account Abstraction

Getting Started

1. Install project dependencies:

yarn install

in our package.json we have already included gelato-raasprotocol-kit the 2. Create a .env file with your private config:

cp .env.example .env

You will need to input your Private Key PK and GELATO_RELAY_API_KEY for sponsored transactions, you an get it at https://relay.gelato.network

Account Abstraction (AA)

As part of the Gelato Raas AA offerings, we have deployed a custom safe-sdk creating following packages

Package	SDK
Safe Protocol Kit	gelato-raas-protocol-kit
Safe AA Kit	gelato-raas-account-abstraction-kit
Safe Relay Kit	gelato-raas-relay-kit

In the Raas AA UI we showcase how to implement AA with web3Auth for social login, Safe as smart contract wallet and Gelato Relay for Gasless transactions. A live demo can be seen here: https://gelato-raas-aa.web.app/

Here we are going to show the how to send Gasless Transactions through a Safe sponsoring the gas with [1Balance] remote removes(https://docs.gelato.network/developer-services/1balance)or paying with the Safe balance (SyncFee)

In both examples we are going to increment()the counter on this simple contract deployed on all Gelato Rollups at "0xEEeBe2F778AA186e88dCf2FEb8f8231565769C27"

Using 1Balance

const safeAccountAbstraction = new AccountAbstraction(signer);
  const sdkConfig: AccountAbstractionConfig = {
    relayPack,
  };
  await safeAccountAbstraction.init(sdkConfig);

  // Create a transaction object
  const txConfig = {
    TO: targetAddress,
    DATA:counterContract.interface.encodeFunctionData("increment", []),
    // Options:
    GAS_LIMIT: gasLimit,
    VALUE:"0"
  };

  const predictedSafeAddress = await safeAccountAbstraction.getSafeAddress();
  console.log({ predictedSafeAddress });

  const isSafeDeployed = await safeAccountAbstraction.isSafeDeployed();
  console.log({ isSafeDeployed });

  const safeTransactions: MetaTransactionData[] = [
    {
      to: txConfig.TO,
      data: txConfig.DATA,
      value: txConfig.VALUE,
      operation: OperationType.Call,
    },
  ];
  const options: MetaTransactionOptions = {
    gasLimit: txConfig.GAS_LIMIT,
    isSponsored: true,
  };

  const response = await safeAccountAbstraction.relayTransaction(
    safeTransactions,
    options
  );
  console.log(`https://relay.gelato.digital/tasks/status/${response} `);

Output

/Users/javiermac/Documents/GELATO/20-RAAS/gelato-raas-starter/src/aa-safe-gasless
{ predictedSafeAddress: '0xf35EAc5DA7d808264a9c7B1C19E2946201320522' }
{ isSafeDeployed: true }

Using SyncFee

Remember to fund your Safe as the gas fees will be deducted from your safe balance

  const gasLimit = "10000000";
  
  const safeAccountAbstraction = new AccountAbstraction(signer);
  const sdkConfig: AccountAbstractionConfig = {
    relayPack,
  };
  await safeAccountAbstraction.init(sdkConfig);

  const txConfig = {
    TO: targetAddress,
    DATA: counterContract.interface.encodeFunctionData("increment", []),,
    VALUE: "0",
    // Options:
    GAS_LIMIT: gasLimit,
    GAS_TOKEN: ethers.constants.AddressZero,
  };

  const predictedSafeAddress = await safeAccountAbstraction.getSafeAddress();
  console.log({ predictedSafeAddress });

  const isSafeDeployed = await safeAccountAbstraction.isSafeDeployed();
  console.log({ isSafeDeployed });

  const safeTransactions: MetaTransactionData[] = [
    {
      to: txConfig.TO,
      data: txConfig.DATA,
      value: txConfig.VALUE,
      operation: OperationType.Call,
    },
  ];
  const options: MetaTransactionOptions = {
    gasLimit: txConfig.GAS_LIMIT,
    gasToken: txConfig.GAS_TOKEN,
    isSponsored: false,
  };

  const response = await safeAccountAbstraction.relayTransaction(
    safeTransactions,
    options
  );
  console.log(`https://relay.gelato.digital/tasks/status/${response} `);

Output

$ ts-node src/aa-safe-gasless/aaSyncFee.ts
{ predictedSafeAddress: '0x68D60c586763879c6614e2eFA709cCae708203c4' }

Working with Safes

We have deployed and verified the the Safe contracts and also we forked the safe sdk to be able to test in OpTest. The forked safe-sdk is published under the package gelato-raas-protocol-kit@1.0.4. The relay-kit and account.abstraction-kit will be published very soon.

Create a Safe

Code can be seen here

yarn create-safe

yarn run v1.22.19
$ ts-node src/create-safe.ts
Network:  { chainId: 42069, name: 'unknown' }
Safe created with address:  0xf35EAc5DA7d808264a9c7B1C19E2946201320522

Increment counter

We have deployed a SimpleCounter contract at "0xEEeBe2F778AA186e88dCf2FEb8f8231565769C27" where we are going to increment the counter through a safe transaciton. Here the code

yarn increment-counter

$ ts-node src/increment-counter.ts
TxHash:  0xce9271aba30a6e68a36f3ce75690ea63e2258d7d9a1d2bb69d58b10ae4fd70d7
