Smart Contract

A smart contract is program code stored at an address on a blockchain that executes deterministically when invoked and maintains its own persistent state.

A smart contract is bytecode deployed to an address that runs when a transaction or another contract calls it. On EVM chains it executes in the virtual machine; its persistent storage holds balances, ownership, and configuration. Because execution is deterministic and public, anyone can verify outcomes, but bugs are immutable once deployed. Contracts back tokens, exchanges, and lending. Our archive RPC lets you read a contract's historical state at any block and replay calls over past state, while decoded data turns its emitted events and inputs into named, queryable fields.
