The same coin exists on several blockchains that don't talk to each other. BNB Chain, Polygon and Ethereum addresses look alike (they all start with "0x"): so a wallet will accept the transfer even on the wrong network.
If it happened:
- don't send again to the same address;
- write to us right away from Profile › Chat with an agent, with the transaction ID (the "hash"), the network used and the amount.
Recovery isn't always possible and can take time. The best protection: pick the same network on both sides before every transfer.
