📡 Interacting with External Contracts

If you need to interact with external contracts (i.e. not deployed with your ETH Mobile instance, e.g DAI contract) you can add external contract data to your packages/reactnative/contracts/externalContracts.ts file, which would let you use ETH Mobile custom hooks.

To achieve this, include the contract name, its address, and abi in externalContracts.ts for each chain ID. Ensure to update the networks in ethmobile.config.ts to your preferred chains to enable hooks typescript autocompletion.

This is the structure of externalContracts object:

const externalContracts = {
  1: {
    DAI: {
      address: "0x...",
      abi: [...],
    },
    WETH: {
      address: "0x...",
      abi: [...],
    },
  },
  5: {
    DAI: {
      address: "0x...",
      abi: [...],
    },
    WETH: {
      address: "0x...",
      abi: [...],
    },
  },
} as const;
