An AMM model that relates two asset reserves through the formula x × y = k.
A swap buys tokens from a constant-product pool, reducing that reserve and increasing the other; the next buyer faces a different price.
An Ethereum account associated with deployed code that runs when it is called.
A lending contract updates your debt when you interact with it, using its code and stored data to decide the result.
The onchain creation of a contract account with executable code.
A change to a contract system’s behavior through a mechanism designed to allow it.
A governance proposal schedules a new implementation, giving users time to read the changes before the proxy begins using it.
The process of matching published source code and compiler settings to a deployed contract’s bytecode.
Before interacting, you check the verified source and discover that an administrator can change a fee, which the app’s homepage never mentioned.
A deterministic digest designed to make reversing it or finding certain matching inputs computationally impractical.
Your node hashes the received transaction data and checks whether the result matches the transaction identifier it was given.
Practical control over the keys or other mechanisms that authorize movement of assets.
A decentralized autonomous organization: a group coordinating decisions and resources through defined rules, often using blockchain contracts.
Community chat: "The treasury proposal is up. We're voting on funding the next development milestone."
A decentralized application with important backend logic or state running on a decentralized network.
Your browser interface calls an exchange's onchain contract after you authorize the transaction in your wallet.
The ability to obtain the data needed to verify or reconstruct a blockchain system's state.
Your rollup node downloads the published batch data and reconstructs balances instead of taking the operator's word for the state.
