Partial hardhat -> viem migration for tests.

Notably all calls to p2pix.callStatic.getStr() were replaced by viem.stringToHex() due to bug in ethers (https://github.com/ethers-io/ethers.js/issues/4965)
Typescript updated to v5.
Full migration to viem might not be possible currently due to hard-chai-matchers incompatibility:
> The hardhat-chai-matchers plugin is designed to work with hardhat-ethers. Attempting to use it in conjunction with hardhat-viem results in compatibility issues.

 ## Usage
 
 ### Pre Requisites
 
-Before installing, create a `.env` file and set the authentication method and other env criteria as in `.env.example`.
+Before installing, create a `.env` file and set a BIP-39 compatible mnemonic and other env criteria as in `.env.example`.
-
-You can authenticate with either:
-- `PRIVATE_KEY` — a raw hex private key (e.g. `0x123...`). Takes priority if both are set.
-- `MNEMONIC` — a BIP-39 compatible 12-word mnemonic phrase. Used as fallback when `PRIVATE_KEY` is not set.
 
 ### Install

-## Deployment (Hardhat Ignition)
+## Deploying to local environment
 
-Deployments are orchestrated by
+On the first teminal, use the following command and import some wallets to your Metamask, then connect to the network pointed:
-[Hardhat Ignition](https://hardhat.org/ignition). Each module declares its
-contracts; Ignition handles ordering, idempotency, and per-network state
-under `ignition/deployments/`.
-
-### Modules
-
-- `ignition/modules/MockToken.ts` — ERC20 mock used in dev / testnets.
-- `ignition/modules/Reputation.ts` — Reputation + Multicall.
-- `ignition/modules/P2PIX.ts` — production deploy (no MockToken). Token
-  addresses passed via parameters (`tokens` + `allowed`).
-- `ignition/modules/P2PIXWithMock.ts` — dev/test deploy. Wires Reputation +
-  MockToken and deploys P2PIX.
-
-### Per-network parameters
-
-Network-specific values (e.g. `defaultBlocks`, `validSigners`, MockToken
-`supply`) live in `ignition/parameters/<network>.json`. Only
-`localhost.json` is checked in; copy it to e.g. `sepolia.json` and set the
-network values before running the deploy script.
-
-### Local environment
-
-On the first terminal:
 
 ```sh
 yarn hardhat node
 ```
 
-On the second terminal:
+On the second teminal, run the following commands:
 
 ```sh
-yarn deploy:mock --network localhost --parameters ignition/parameters/localhost.json
+yarn deploy1:localhost
+yarn deploy2:localhost
 ```
 
-Addresses for every deployed contract are written to
+**_NOTE_:** The second script transfers 2M tokens to the first wallet of the node.
-`ignition/deployments/chain-31337/deployed_addresses.json` (this path is
+To use the P2Pix smart contract first transfer some of the tokens to other wallets.
-gitignored — local-only state).
 
-### Testnets
+## Deploying to testnets
+
+Deploy to Ethereum's Goerli testnet:
 
 ```sh
-yarn deploy:mock --network sepolia
+yarn deploy1:goerli
+yarn deploy2:goerli
 ```
 
-Requires the matching `ignition/parameters/sepolia.json` and the relevant
+Deploy to Polygon's Mumbai testnet:
-API keys in `.env`.
 
-### Production (real tokens)
+```sh
-
+yarn deploy1:mumbai
-Use the `P2PIX` module when the target network already has the ERC20
+yarn deploy2:mumbai
-tokens you want P2PIX to support — no MockToken is deployed.
+```
-
-1. Copy `ignition/parameters/prod.example.json` to
-   `ignition/parameters/<network>.json` and set:
-   - `defaultBlocks`, `validSigners`
-   - `tokens` — array of ERC20 addresses on the target network
-   - `allowed` — array of booleans, same length as `tokens`
-2. Run:
-
-   ```sh
-   yarn deploy --network <network> --parameters ignition/parameters/<network>.json
-   ```
-
-The deployed Reputation/Multicall/P2PIX addresses are written to
-`ignition/deployments/chain-<id>/deployed_addresses.json`.
