You sent it on the wrong network
The money is almost never gone in the way people fear. It is sitting at that address on the chain you sent it on, exactly where the ledger says it is. Whether you can get it back depends on one question: does anyone control that address on that chain?
The three cases
If the address is one you hold the key to on an EVM chain, the funds are yours: the same key opens it on every EVM chain, and you need a wallet that will show that chain. A deposit address this wallet issues is not one of those: no key of yours opens it, on any chain. If it belongs to an exchange, recovery depends on their policy and their staff, and it is a support ticket, not a technical problem. If it is a contract or an address nobody holds the key to, it is gone.
Why this happens at all
Every EVM chain shares the same address format. The same 0x string is a valid address on Ethereum, BNB Chain, Polygon, Arbitrum, Base, Optimism and Avalanche, so nothing about the string tells you which one was meant. Tron and Solana formats are distinct, which is precisely why sending to them by mistake is rare.
What this wallet does about it
The network is chosen with the asset, before the address is asked for, so the pair is fixed by the time you paste anything. That prevents the ordinary version of this mistake. It cannot prevent an exchange giving you an address for a chain they did not mean.
What to do first
Do not send a second transfer to "test" it. Find the transaction on the explorer for the chain you actually used, save the hash, and check who controls the destination. If it is an exchange, open a ticket with the hash and the chain named explicitly. That is the information their recovery process needs and the thing people usually leave out.

Several wallets in one account, separate on-chain
Hold as many wallets as you need inside one Telegram account. Each is its own account on-chain, and nothing links them until you move money between them, so paying from one tells nobody about the others. Send to a @username or to any address.
Questions
Are the funds destroyed?
No. They are at that address on that chain. Whether they can be moved depends on who holds its key.
What if I sent to my own address on the wrong EVM chain?
If you hold its key, that key controls the address on every EVM chain: use a wallet that lets you select the chain you sent on, and the balance is there. A deposit address from this wallet is not one you hold a key to, and no wallet, this one included, opens it on another chain.
Can the wallet reverse it?
No. Nobody can reverse a settled transfer. Our share of the key cannot sign alone, and we have no special power over any chain.
