Flash on original contracts (TRC20 / TON / SOL)
On smart-contract networks with managed infrastructure, flash more often uses real stablecoin contracts but exploits centralization: master nodes, delegation, energy, and freeze policy.
Tron: a typical Flash USDT TRC-20 scenario uses network resources (energy/bandwidth) and trusted nodes to show a transfer. It may involve paying a fraction of face value, then blocking infrastructure and freezing recipient addresses on the USDT contract.
TON and Solana: after public vulnerabilities, discussions covered temporary token display, sponsored transactions, and non-standard program IDs. Complexity exceeds UTXO chains, so “legitimate” explorer views are more misleading.
BTC/ETH alone do not offer the same issuer-contract flexibility; schemes migrate to TRC20/TON/SOL. This page is informational, not a how-to.
