component

Replace any AddressInput for example in packages/nextjs/app/debug/_components/contract/ContractInput.tsx you can add the import and replace the AddressInput with MagicAddressInput:

import { MagicAddressInput } from "~~/components/ext/MagicAddressInput"; // add this import
//...
export const ContractInput = ({ setForm, form, stateObjectKey, paramType }: ContractInputProps) => {
//...
  const renderInput = () => {
    switch (paramType.type) {
      case "address":
        return <MagicAddressInput {...inputProps} />; // replace `return <AddressInput {...inputProps} />;`
//...

hook - add custom suggestions

Below you'll find an example of how you can add an address every time the user submits a successful write transaction in packages/nextjs/app/debug/_components/contract/WriteOnlyFunctionForm.tsx.

import { useMagicAddressBook } from "~~/hooks/ext/useMagicAddressBook"; // add this import
// ...
export const WriteOnlyFunctionForm = ({
  abi,
  abiFunction,
  onChange,
  contractAddress,
  inheritedFrom,
}: WriteOnlyFunctionFormProps) => {
const { addAddress } = useMagicAddressBook(); // add this line
// ...
  const handleWrite = async () => {
// ...
        await writeTxn(makeWriteWithParams);
        // add below block
        Object.keys(form).forEach(key => {
          if (key.endsWith("_address")) {
            const [contractName, inputName] = key.split("_");
            addAddress(form[key], `${contractName} ${inputName} -`);
          }
        });
// ...
