Ethbox is an Ethereum messaging protocol that enables any wallet to bid ETH to send messages to another wallet. Ethbox is the world’s first peer to peer attention marketplace, allowing users to bid on attention that is valuable to them, and monetize their attention if it is valuable to others. Ethbox’s infrastructure is 100% on-chain, allowing for composition, derivatives and other emergent use-cases. All tokens are soul bound to the minting address, and each unique address can mint their SBT Ethbox.
