Address
A public identifier used to receive assets or interact with a blockchain account. It does not reveal the private key.

Account abstraction
A wallet design that moves account rules into programmable logic so authentication, recovery, batching, and fee payment can be customised.
Address
A public identifier used to receive assets or interact with a blockchain account. It does not reveal the private key.
Bitcoin
A public network and scarce digital asset that uses proof of work to order transactions without a central operator.
Block
An ordered batch of validated transactions added to a blockchain’s shared history.
Bridge
A system that coordinates assets or messages between separate networks using a particular custody and verification model.
Confirmation
Evidence that a transaction has been included in the network history and is becoming harder to replace.
Consensus
The rules and incentives that let distributed participants agree on a valid transaction history.
Crypto wallet
Software or hardware that manages signing keys and prepares instructions for blockchain accounts.
Custody
The arrangement that determines who can authorise transactions and restore access to assets.
DeFi
Financial applications implemented through smart contracts, often allowing users to trade, lend, or borrow directly from a wallet.
Ethereum
A programmable public blockchain used for smart contracts, tokens, and decentralised applications.
Finality
The point at which a network treats a transaction or block as practically or cryptographically irreversible.
Gas
The unit used to measure computational work and calculate transaction fees on networks such as Ethereum.
Hardware wallet
A dedicated device designed to isolate private keys and sign transactions away from a general-purpose computer.
Liquidity
The available depth for buying, selling, borrowing, or redeeming an asset without a large price impact.
MPC
Multi-party computation: protocols that let several participants compute a signature without reconstructing one complete private key.
NFT
A token whose identifier and metadata distinguish it from otherwise interchangeable units.
Private key
Secret signing material that proves authority over a blockchain account. Anyone with the key can usually authorise its transactions.
Proof of stake
A consensus family in which validators place capital at risk and participate in proposing and confirming network history.
Proof of work
A consensus family that uses costly computation to make block production competitive and attacks expensive.
Seed phrase
A human-readable backup from which a wallet can derive its private keys. Exposure usually means loss of control.
Smart contract
Code deployed to a blockchain that applies deterministic rules to transactions and stored state.
Token
A digitally represented unit created and managed by a protocol or smart contract.
Transaction
A signed instruction that asks a network to transfer value or execute application logic.
Validator
A participant that checks transactions and helps a proof-of-stake network agree on its history.
Volatility
The speed and magnitude of price changes over time. High volatility increases both opportunity and loss risk.
