fix: wagmi write contract params

[enesozturk]

Description

When sending ERC20 tokens, there is an issue with the writeContract method parameters where we get the following error when sending transactions using Wagmi adapter:

W3mWalletSendPreviewView:onSendClick - error sending transaction AppKitError: An unknown error occurred while executing the contract function "transfer".

Request Arguments:
  chain:  undefined (id: 30)
  from:   0xa9054cea9db7965C1dbDe7aa14aAa39ecda98F14
  to:     0x2AcC95758f8b5F583470ba265EB685a8F45fC9D5
  data:   0xa9059cbb000000000000000000000000a462ca0adfda8037ecac46fb0cecde8d103fd93e00000000000000000000000000000000000000000000000006f05b59d3b20000
 
Contract Call:
  address:   0x2AcC95758f8b5F583470ba265EB685a8F45fC9D5
  function:  transfer(address _to, uint256 _value)
  args:              (0xa462ca0adfda8037ecac46fb0cecde8d103fd93e, 500000000000000000)
  sender:    0xa9054cea9db7965C1dbDe7aa14aAa39ecda98F14

Details: Cannot convert eip155:30 to a BigInt
Version: [email protected]
    at getContractError (getContractError.ts:78:10)
    at writeContract (writeContract.ts:208:27)
    at async writeContract (writeContract.ts:108:16)
    at async WagmiAdapter.writeContract (client.ts:436:16)
    ...

As seen in Details: Cannot convert eip155:30 to a BigInt, the Wagmi is getting the chain object with wrong parameters and finding the CAIP id from the network object. Passing the right Wagmi chain object to chain and removing chainId parameter (Viem doesn't have chainId param, see docs).

Steps to reproduce

• Go to https://lab.reown.com/appkit/?name=multichain-all
• Connect with Embedded Wallet
• Try sending some ERC20 wallet (1)
• Confirm sending

*(1): Bc we use writeContract only when the token user want to send is ERC20, in SendController.

Note

Fixes writeContract to pass the correct Wagmi chain and updates tests; also adds Rootstock networks to lab constants.

• Adapters (packages/adapters/wagmi/src/client.ts):
  • Update writeContract to resolve wagmiChain by chain.id and pass it via chain; remove chainId usage.
• Tests (packages/adapters/wagmi/src/tests/client.test.ts):
  • Use Address for typed params; assert wagmiWriteContract is called with chain and correct args.
• Lab app networks (apps/laboratory/src/utils/ConstantsUtil.ts):
  • Add rootstock and rootstockTestnet to EvmNetworks.
• Changeset:
  • Patch release for @reown/appkit-adapter-wagmi noting writeContract param fix.
