Cardano Address

Overview

A Cardano address identifies conditions for controlling transaction outputs. Shelley-era formats include base, enterprise, pointer, and reward addresses, combining payment credentials, staking credentials, or references depending on the address type.

Addresses use network tags and encoded checksums, helping wallets distinguish mainnet from test environments. A valid address can receive ada and Cardano native assets, but receiving an asset does not prove its authenticity or policy identity. Wallets and payment services should validate the network, address type, and full encoding before submission. Deposit systems need to monitor UTXOs and asset policy identifiers rather than treating the address as an account balance. Stake credentials and reward accounts have different purposes from ordinary payment destinations and should not be substituted. A string that passes a format check can still belong to the wrong chain, unsupported asset, contract type, or destination that requires a memo or tag. Cardano Address must be interpreted with its network, address or account type, encoding rules, and any required routing fields.

Cardano Address is an identifier or spendable object, not proof of legal ownership and not a secret credential. Authorization depends on keys, scripts, contracts, or protocol rules, while custodial systems may expose an identifier without giving the user direct control of the underlying account. Normalization, case conversion, truncation, and alias resolution need protocol-aware rules, because a visually similar value can represent a different destination or fail checksum validation. Systems storing Cardano Address should preserve the exact value together with chain identifiers and type metadata. Settlement consideration: Cardano addresses encode payment, staking, and network context, so address type and asset policy must be validated.
