# What is StableNet

> StableNet is an EVM-compatible, KRW-backed blockchain built for stablecoin operations with governance-managed validators and supply.

> StableNet is an EVM-compatible Proof-of-Authority blockchain where the native gas token is a KRW-pegged stablecoin (WKRC) and transaction fees are predictable by design.

StableNet extends go-ethereum with three additions: Anzeon WBFT consensus, five governance system contracts, and a stablecoin-optimized gas policy. Every contract you write in Solidity runs without modification.

## Anzeon WBFT Consensus

StableNet uses Anzeon WBFT (an enhanced QBFT variant) as its consensus engine. Validators are managed on-chain through the GovValidator contract rather than through staking.

Key properties:

* **No staking** — validators are approved through governance voting
* **No block rewards** — supply changes only via mint/burn
* **BLS signature aggregation** — reduces consensus message overhead
* **1-second finality** — blocks are final once committed (no reorgs under normal operation)

## WKRC (KRW-Pegged) Native Coin

WKRC (KRW-pegged) is both the gas token and the primary stablecoin. It is exposed as a standard ERC-20 token via the NativeCoinAdapter system contract at `0x0000000000000000000000000000000000001000`.

| Property       | Value                                        |
| -------------- | -------------------------------------------- |
| Symbol         | `WKRC`                                       |
| Decimals       | 18                                           |
| Peg            | Korean Won (KRW)                             |
| ERC-20 address | `0x0000000000000000000000000000000000001000` |
| Standard       | ERC-20, FiatTokenV2\_2 compatible            |

`balanceOf(address)` and gas balance are the same value — the same WKRC used to pay gas can also be transferred or approved like any ERC-20 token.

## Five System Contracts

Five governance contracts are deployed at genesis and can only be upgraded via hard fork:

| Contract          | Address   | Purpose                                     |
| ----------------- | --------- | ------------------------------------------- |
| NativeCoinAdapter | `0x…1000` | ERC-20 wrapper for WKRC                     |
| GovValidator      | `0x…1001` | Validator set and gas tip governance        |
| GovMasterMinter   | `0x…1002` | Minter registry                             |
| GovMinter         | `0x…1003` | Mint/burn proposal voting                   |
| GovCouncil        | `0x…1004` | Blacklist and authorized account management |

## EVM Compatibility

StableNet runs the **Anzeon** EVM instruction set, which includes London + Shanghai opcodes. Blob opcodes (`BLOBHASH`, `BLOBBASEFEE`) from Cancun are not supported. Set `evmVersion: "shanghai"` in your Hardhat or Foundry config.

## Developer benefits

* Your existing Solidity contracts, ethers.js, viem, Hardhat, and Foundry tooling work without modification
* `tx.origin` and `msg.sender` behave identically to Ethereum
* Fee Delegation (type `0x16`) lets you sponsor gas for users without changing contract logic
* Gas fees are priced in WKRC (KRW), making cost estimates predictable in fiat terms
