With the growing cross-chain ecosystem combined with the rise of smart contract wallets, a wallet address has become a very poor identifier for the human we intend to send an asset to. To accurately send assets, we have to ask questions like:

What asset do you want to receive?
On what chain?
To which address?

Failing to collect this information from the recipient can be an inconvenience (at best) or lead to lost funds (at worst).

Vitalik and others have proposed new addressing schemes that include information about the chain on which an address should receive assets, but that requires a significant ecosystem shift.

Wallet Hopper enables a simple wallet address to express full details about how you want to receive each asset.
