Main Features

• Create EGLD/Token/MetaESDT/NFT/SFT transactions for Smart Send contracts

Quick start guide

Basic example

provider = ProxyNetworkProvider("https://devnet-gateway.multiversx.com")
account = provider.get_account(Address.from_bech32("MY_ADDRESS"))
network_config = provider.get_network_config()
config = DefaultTransactionBuildersConfiguration(network_config.chain_id)

smart_send = SmartSend(account, config, "MY_CONTRACT_BECH32_ADDRESS")

input_transactions: List[TokenAmount] = []
for i in range(1, 10):
    input_transactions.append(TokenAmount("RECEIVER_ADDRESS", TokenPayment.egld_from_amount(f"0.0{i}"))) # TokenPayment can also be fungible_from_amount / meta_esdt_from_amount / non_fungible / semi_fungible

try:
    # You can sync the account before creating transactions (to have the latest nonce)
    # account = provider.get_account(Address.from_bech32("MY_ADDRESS")) # get account data from network
    # smart_send.sync(account) # sync account

    txs = smart_send.create_egld_transactions(input_transactions) # or create_token_transactions / create_metaesdt_transactions / create_nft_transactions / create_sft_transactions
    # sign and send txs
except Exception as ex:
    print(ex)

Advanced example

The following example is using a wallet signer that should not be used in production, only in private!

provider = ProxyNetworkProvider("https://devnet-gateway.multiversx.com")
account = provider.get_account(Address.from_bech32("MY_ADDRESS"))
network_config = provider.get_network_config()
config = DefaultTransactionBuildersConfiguration(network_config.chain_id)

signer = UserSigner.from_pem_file(Path("/path/wallet.pem"))

smart_send = SmartSend(account, config, "MY_CONTRACT_BECH32_ADDRESS")

input_transactions: List[TokenAmount] = []
for i in range(1, 10):
    input_transactions.append(TokenAmount("RECEIVER_ADDRESS", TokenPayment.egld_from_amount(f"0.0{i}")))

try:
    txs = smart_send.create_egld_transactions(input_transactions)
    for tx in txs:
        tx.signature = signer.sign(tx)

    response = provider.send_transactions(txs)
    print(response)
except Exception as ex:
    print(ex)
