Orb Attestation Wrapper Example

The purpose of this repo is to provide a quick example of how to wrap an existing contract to enable RallyTransact gasless transactions and then call the contract from a simple Flutter app. In this example we wrap the Orb Attestation contract with a contract that supports RallyTransact gasless transactions. The contract wrapper is implemented in /contracts/src/OrbAttestationWrapper.sol and an example flutter app calling the contracts is at /app.

The example app calls the transfer() method on the Orb Attestation contract using the following test inputs.

{
  "token": "0x41e94eb019c0762f9bfcf9fb1e58725bfb0e7582",
  "fromProfileId": "702",
  "from": "0xfebc231959550ffecd1ad1ae22a3d6bb55471b6a",
  "toProfileId": "246",

  "amount": "10",

}

An example test transaction showing successful contract execution can be found here

Note: there are two examples of supporting RallyTransact with the existing OrbAttestation contract.

1. contracts/src/OrbAttestationWrapper a wrapper contract that wraps the existing contract with a contract that supports RallyTransact

2. contracts/src/OrbAttestationRallyTransact.sol a contract that extends the existing Orb Attestation contract to support RallyTransact.
