Tokens & Standards¶
PezkuwiChain has a dual-token economy and a small, familiar family of token standards.
The two native tokens¶
| Token | Role | Notes |
|---|---|---|
| HEZ | Native gas & security token | Pays transaction fees; staked by validators/nominators to secure the network. Inflationary, with a 48-month synthetic halving schedule for rewards. |
| PEZ | Governance token | Used for governance and treasury. The PezTreasury launched with an initial supply on the order of 5 billion PEZ. |
On Asset Hub, the canonical representations at genesis are PEZ (Asset ID 1) and wHEZ (Asset ID 2, wrapped HEZ).
HEZ vs PEZ-20
Just as ETH itself is not an ERC-20 token, HEZ — the native gas token — is
not a PEZ-20 token. It lives in the Balances pallet. PEZ-20 is the
standard for issued assets registered on Asset Hub.
Token standards: PEZ-20 & PEZ-721¶
PezkuwiChain defines token standards so that anyone coming from Ethereum (ERC-20 / ERC-721), BNB Chain (BEP-20), or Tron (TRC-20) instantly understands how tokens work here.
| Standard | What it is | Backed by |
|---|---|---|
| PEZ-20 | Fungible tokens (currencies, stablecoins, LP tokens) | pallet-assets on Asset Hub |
| PEZ-721 | Non-fungible tokens (NFTs, collectibles, certificates) | pallet-nfts on Asset Hub |
These are not smart-contract standards
Pezkuwi Asset Hub has no EVM and no smart-contract layer. PEZ-20 and PEZ-721 are runtime-native standards: a token is not a deployed contract with an address — it is a registered asset with an on-chain ID managed directly by the runtime. This makes tokens cheaper, faster, and impossible to brick with buggy contract code.
PEZ-20 — fungible tokens¶
A PEZ-20 token is a fungible asset in the Assets pallet, identified by a numeric
Asset ID (the equivalent of an ERC-20 contract address).
| Concept | Ethereum (ERC-20) | Pezkuwi (PEZ-20) |
|---|---|---|
| Token identity | Contract address 0x… |
Asset ID (u32) |
| Where it lives | A deployed contract | The Assets pallet registry |
| Native coin | ETH is not an ERC-20 | HEZ is not a PEZ-20 (it's in Balances) |
| Metadata | name, symbol, decimals |
name, symbol, decimals (on-chain) |
Typical PEZ-20 tokens you may see in wallets and on the exchange include USDT (PEZ-20) — i.e. USDT issued on Pezkuwi Asset Hub, shown with a "PEZ-20" badge the same way other chains show "USDT TRC-20" or "USDT ERC-20".
PEZ-721 — non-fungible tokens¶
PEZ-721 covers NFTs, collectibles, and certificates, backed by pallet-nfts.
Collections and items each have on-chain IDs and metadata.

How "PEZ-20" appears in apps¶
Different apps follow their own existing convention for labeling networks:
- PEX exchange and the mini app / pwap: assets like USDT show a "PEZ-20 (Pezkuwi Asset Hub)" badge — the same pattern they use for TRC-20 / ERC-20.
- Pezkuwi Wallet: shows the chain name only (e.g. "Pezkuwi Asset Hub"), consistent with how it shows "Ethereum" rather than "ERC-20".
