Neo Mamba SDK

Installation

pip install neo-mamba

Quick Start

import asyncio
from neo3.api.wrappers import ChainFacade, NeoToken, GasToken
from neo3.wallet.wallet import Wallet

async def check_balance():
    # Connect to mainnet
    facade = ChainFacade.node_provider_mainnet()

    # Get NEO balance
    neo = NeoToken()
    address = "NUVaphUShQPD82yoXcbvFkedjHX6rUF7QQ"
    balance = await facade.test_invoke(neo.balance_of(address))
    print(f"NEO Balance: {balance}")

    # Get GAS balance
    gas = GasToken()
    gas_balance = await facade.test_invoke(gas.balance_of(address))
    print(f"GAS Balance: {gas_balance / 1e8}")  # 8 decimals

asyncio.run(check_balance())

Transfer Example

import asyncio
from neo3.api.wrappers import ChainFacade, NeoToken
from neo3.api.helpers.signing import sign_with_account
from neo3.network.payloads.verification import Signer
from neo3.wallet.wallet import Wallet

async def transfer_neo():
    # Load wallet
    wallet = Wallet.from_file("./wallet.json")
    account = wallet.account_default

    facade = ChainFacade.node_provider_mainnet()
    facade.add_signer(
        sign_with_account(account),
        Signer(account.script_hash)
    )

    # Transfer NEO
    neo = NeoToken()
    receipt = await facade.invoke(
        neo.transfer(account.address, "NZwvGPNXprXj2KnKEFbpz3aG87bGECZThL", 10)
    )
    print(f"Transaction: {receipt.tx_hash}")

asyncio.run(transfer_neo())

NeoFS Integration

REST Gateway

NeoFS provides a REST API gateway for easy integration:

Base URL: http://localhost:8090/v1 (self-hosted)

Upload Object

curl http://localhost:8090/v1/get/{containerId}/{objectId}

NeoX (EVM Sidechain)

NeoX is Neo's EVM-compatible sidechain with:

• dBFT consensus with immediate finality
• Anti-MEV capabilities
• Native bridge to Neo N3
• < $0.01 gas costs
• >1,000 TPS throughput

Connect with ethers.js

const provider = new ethers.JsonRpcProvider("https://mainnet-1.rpc.banelabs.org");
const chainId = await provider.getNetwork().then(n => n.chainId);
console.log(`Connected to NeoX (chain ID: ${chainId})`);

Token Standards

NEP-17 (Fungible Tokens)

Standard methods:

• symbol() - Token symbol
• decimals() - Decimal places
• totalSupply() - Total supply
• balanceOf(account) - Account balance
• transfer(from, to, amount, data) - Transfer tokens

NEP-11 (Non-Fungible Tokens)

Standard methods:

• symbol() - Collection symbol
• decimals() - Always 0 for NFTs
• totalSupply() - Total NFTs minted
• balanceOf(owner) - NFT count for owner
• tokensOf(owner) - List token IDs for owner
• ownerOf(tokenId) - Owner of specific NFT
• transfer(to, tokenId, data) - Transfer NFT

Best Practices

1. Always Validate Addresses: Neo addresses start with "N"
2. Check GAS Balance: Ensure sufficient GAS for transaction fees
3. Use Testnet First: Test transactions on testnet before mainnet
4. Secure Wallet Files: Encrypt and backup wallet JSON files
5. Verify Contract Hashes: Always verify contract script hashes

Security Warnings

• Never share private keys or wallet passwords
• Verify contract addresses before interactions
• Be cautious of unverified contracts
• Use hardware wallets for significant holdings
• Keep wallet software updated

Example Queries

1. "Check my NEO balance for address N..."
2. "Transfer 10 GAS to address N..."
3. "Get the total supply of NEO"
4. "Query a NEP-17 token contract"
5. "What's the current block height on Neo N3?"

Context Variables

• {{action}}: Operation to perform
• {{address}}: Neo N3 address
• {{contract_hash}}: Contract script hash
• {{network}}: Network (mainnet/testnet)
