A wallet that monitors addresses or public derivation data without holding their spending keys.
"The balance is right there on my laptop, but signing still happens on the separate offline device."
A broad label for internet applications using blockchains for functions such as ownership, payments or coordination.
You connect a wallet and interact with the onchain app, while its web interface still arrives from conventional hosting.
The smallest whole unit of ether: one ETH equals 10¹⁸ wei.
A wallet displays 0.01 ETH while the transaction request records 10,000,000,000,000,000 wei.
Wrapped ether: an ERC-20 token representation of ETH created by a wrapping contract.
A token that represents another asset through a wrapping or bridging arrangement.
"The bridge gave me a wrapped token on the destination chain; the original asset is locked on the source chain."
Using crypto positions or protocols to seek returns from interest, fees or incentives.
A cryptographic way to demonstrate a claim without revealing the secret information used to establish it.
"I can prove I'm eligible without sending you the private credential that establishes it."
A rollup that uses cryptographic validity proofs to demonstrate correct execution of transaction batches.
A succinct, non-interactive argument of knowledge that can demonstrate a claim with a compact zero-knowledge proof.
The verifier receives a compact proof that the computation followed its rules, without seeing the private witness or running interactive rounds.
A zero-knowledge form of a scalable, transparent argument of knowledge, typically using hash-based techniques.
The batch's execution is proved with a transparent setup, without a secret trusted-setup ceremony.
