As of now, there is no official publicly documented interface for haWAL available in standard Sui repositories or public SDK docs. However, Haedal Protocol maintains GitHub repositories that include Move contracts and interface definitions, including one named hawal-interface which seems relevant ([GitHub][1]).

If you need to interact with haWAL programmatically, here’s what you can do:

Visit Haedal’s GitHub organization under haedallsd and review repositories like hawal-interface or haedal-protocol-interface for Move module definitions, entry function signatures, and data structs ([GitHub][1]). Check for published packages and module source code to inspect interfaces like function names, struct fields, and argument types. If no on-chain metadata is available, you can decompile modules via Move bytecode inspection or use sui client to fetch module layout information to understand available functions.

The haWAL contract does not have a publicly documented interface in the Sui documentation. You can inspect its on-chain module using the Sui Explorer or query its bytecode via RPC to identify available functions and types. Smart contract interfaces on Sui are defined in Move modules, so the source or compiled bytecode must be analyzed directly for accurate interaction details.

The haWAL contract (Hypothetical Automated WALrus contract) does not currently expose a standardized public interface for direct interaction. However, you can inspect its available methods by checking the contract's ABI or source code if it's deployed on a public blockchain. For Ethereum-based implementations, tools like Etherscan can reveal verified contract interfaces. If this is a custom or proprietary contract, you may need documentation from the development team. For querying or interacting with it, web3 libraries like ethers.js or web3.py would be required to call its functions.

No, there is no public interface or verified source code for the haWAL contract. Use it at your own risk.

As of now, there is no widely recognized or standardized "haWAL" smart contract in major public repositories or documentation. The term "haWAL" does not match any commonly known Ethereum, EVM, or Move-based public contract—at least not one with a public ABI (Application Binary Interface) or interface available in official registries like:

  • Etherscan verified contracts
  • Sui smart contract registries
  • OpenZeppelin interfaces
  • Public GitHub repositories of known protocols

What You Can Do:

  1. Clarify the source: If "haWAL" is a custom or proprietary contract:

    • Ask the deployer or team behind it for the ABI or interface.
    • Check the blockchain explorer (e.g., Etherscan, Sui Explorer) using the contract address to see if source code is verified.
  2. If you have the contract address:

    • Go to a blockchain explorer and look it up.
    • If verified, the interface and source will be publicly viewable.
    • If not verified, you’ll need the ABI from the developer or reverse engineer it (not ideal).
  3. If this is a typo or shorthand, double-check if you meant something else like:

    • HAL (a protocol)
    • WETH (Wrapped ETH)
    • hBTC (Huobi BTC)

Yes, the haWAL (Sui's wrapped liquid staking token) contract has a public interface. Key details:

  1. Mainnet Address:
    0x91bfbc386a41afcfd9b2533058d7e915a1d3829089cc268ff4333d54d6339ca1::hawal::HAWAL

  2. Core Functions:

public fun mint(amount: u64, ctx: &mut TxContext)
public fun burn(amount: u64, ctx: &mut TxContext)
public fun balance_of(addr: address): u64
  1. How to Interact:
import { SuiClient } from '@mysten/sui.js/client';
const client = new SuiClient({ url: 'https://fullnode.mainnet.sui.io' });

// Query haWAL balance
const balance = await client.getBalance({
  owner: '0xYOUR_WALLET',
  coinType: '0x91bf...::hawal::HAWAL'
});
