wallet_getCapabilities Usage

To check if a wallet supports ERC-7677, you can inspect its response to an EIP-5792 wallet_getCapabilities request. If the wallet supports ERC-7677, it will have a paymasterService capability with a supported field set to true for each chain it supports paymaster services on.

If you are an app developer, you might want to do this so you can display to your users that their transaction will be sponsored.

Example

provider.request({
  method: 'wallet_getCapabilities',
  params: ['0xd46e8dd67c5d32be8058bb8eb970870f07244567']
})
{
 
  "0x2105": {
 
    paymasterService: {
 
      supported: true,
 
    }
 
  }
 
}
