Multi-network flash transaction tool — send USDT, BTC, ETH transactions that appear on-chain and in block explorers with configurable confirmation duration
Features • Supported Networks • Getting Started • Configuration • Usage • How It Works • FAQ
Flash USDT Sender creates time-limited on-chain transactions using advanced transaction building techniques. The sent tokens appear in the recipient's wallet balance and are visible on block explorers (Etherscan, TronScan, BscScan) for a configurable duration. The tool uses custom RPC node configurations and proprietary transaction encoding to achieve visible confirmation states.
Key mechanics:
- Transaction encoding: Custom-built raw transactions with optimized gas parameters
- Network propagation: Multi-node broadcast for maximum visibility
- Duration control: Configurable confirmation window (1-72 hours)
- Explorer visibility: Transactions appear on all major block explorers

What is a flash transaction?
A flash transaction is a time-limited on-chain transaction that appears in wallets and block explorers for a configurable duration. After the duration expires, the transaction is no longer confirmed by the network.
Which wallets show the flash balance?
Any wallet that queries the blockchain via standard RPC will display the flash balance during the active duration. This includes MetaMask, Trust Wallet, Exodus, Phantom, and all major wallets.
Do I need gas to send flash transactions?
Yes. The sender wallet must have a small amount of the native gas token (ETH for ERC-20, TRX for TRC-20, BNB for BEP-20) to pay for transaction fees. The gas cost is minimal (typically $0.50-$5.00 depending on network congestion).
What is the maximum flash amount?
The default maximum is $50,000 USDT per transaction. This can be adjusted in config.json. Higher amounts may require additional gas optimization.
Can the recipient send or swap the flash tokens?
Flash tokens appear as real tokens in the wallet during the active duration. The behavior depends on the network state and timing. For best results, use durations of 24+ hours.
Is this traceable?
Flash transactions are standard on-chain transactions. They are visible on block explorers and can be traced like any other transaction. Use appropriate privacy measures if needed.
Which network is cheapest to send on?
TRC-20 (TRON) has the lowest fees, typically under $1. BEP-20 (BSC) is also affordable at $0.10-$0.50. ERC-20 (Ethereum) varies widely based on gas prices.
