SafeSend

Destination-safe Web3 transfers with intelligible Safe IDs.

SafeSend reduces wrong-recipient risk by replacing raw destination-address sharing with intelligible Safe IDs and a recipient-bound, proof-verified claim flow. SafeSend helps users avoid irreversible destination mistakes by making transfer routing human-intelligible first, then cryptographically verifiable.
