Comments / Remarks

Expected behavior

  • wallet_addEthereumChain: Adds a new chain to the wallet if it’s not already recognized, and switches to it.
  • wallet_switchEthereumChain: Switches to a recognized chain; fails if the chain is not already added to the wallet.
  • wallet_watchAsset: Adds a new asset to the wallet if it’s not already recognized.
  • wallet_requestPermissions: Requests specific permissions from the wallet, triggering a modal for user approval.
  • wallet_getPermissions: Retrieves the list of permissions the dApp currently has from the wallet.
  • wallet_revokePermissions: Revokes previously granted permissions from the dApp.

Metamask

  • wallet_requestPermissions and wallet_getPermissions: Returns a full response containing all permission fields according to the specification.

Coinbase Wallet

  • wallet_addEthereumChain: It does not fully adhere to the specification, as it changes the network temporarily but doesn’t save it. As a result, if the wallet does not natively support the network, following up with wallet_switchEthereumChain for the same network will fail.
  • wallet_watchAsset: The wallet responds with a modal with the following message: "Coinbase Wallet automatically tracks token ownerships on the Ethereum network. There is no need to import USDC."

Trust Wallet

  • General Behavior is very similarly to MetaMask.
  • wallet_watchAsset: Requires symbol and decimals fields, which are optional according to the specification and in other wallets.

Enkrypt

  • wallet_requestPermissions: Returns a limited response object, but no permissions appear to be granted, and no modal is shown to request user approval.

Rainbow

  • wallet_addEthereumChain: Adds a chain but does not switch to it; fails if the network is already known to the wallet.

Rabby Wallet

  • wallet_requestPermissions and wallet_getPermissions: Returns a response object containing only parentCapability, but functions as expected.

Exodus

  • wallet_addEthereumChain and wallet_switchEthereumChain: Only work with chains natively supported by the wallet; new chains cannot be added.
  • wallet_watchAsset: The promise resolves successfully with a value of true, but no asset is actually added.
  • wallet_requestPermissions and wallet_getPermissions: Returns a response object containing only parentCapability, but functions as expected.
  • wallet_revokePermissions: Revokes permissions but also triggers an error: DisconnectedError: The provider is disconnected from all chains. This appears to be an issue with the wallet itself.

Phantom

  • wallet_addEthereumChain and wallet_switchEthereumChain: Only work with chains natively supported by the wallet; new chains cannot be added.

Uniswap Extension

  • wallet_switchEthereumChain: Only works with chains natively supported by the wallet; new chains cannot be added.
