iEscrow is multi-network: it separates the *asset* (e.g. USDT) from the *network* it travels on (Ethereum, Tron, etc.). That's why every time you deposit or withdraw, you choose currency + network.
The network matters: USDT on Ethereum and USDT on another network are the same currency but have different addresses and fees. Always deposit/withdraw on the network that matches the address.
In crypto-to-crypto trades, each side can receive on the network they prefer; the escrow manages one wallet per side and per network.
