Glossary

Chain ID - It is a unique identifier that represents a blockchain network. It can be used in an application to distinguish different blockchain networks from each other and to ensure that transactions and messages are sent to the correct network.

Client ID - The client_id is a public identifier for apps.

Client Secret - The client_secret is a secret known only to the application and the authorization server.

Custodial Wallets - Custodial wallet is a wallet in which a third party (usually a crypto exchange) is responsible for managing your private keys.

EOA - Externally Owned Accounts. They are the most common type of blockchain account for direct control. These accounts are created using private keys. The associated key gives you a unique signature and access to the blockchain, which can be used to send and receive transactions and interact with applications.

Extrinsic - Particularly in Substrate-based blockchains like Polkadot, "extrinsic" are actions or transactions that originate from an external source, outside of the blockchain runtime, and are submitted to the blockchain for processing. Extrinsic is a term specific to Substrate's framework.

Auth - It is an all-in-one smart wallet. Auth is a unified platform to manage identity data, assets, permissions, and status across various apps, experiences, and worlds, ensuring a simpler and safer journey.

Non-Custodial - Non-custodial wallets are a type of wallet in which the crypto owner holds their own private key and, therefore, their funds.

OICD - OpenID Connect.

Signer - An abstraction on externally owned wallet accounts allowing the signing of messages, transactions, and TRN pallet extrinsics. A Signer allows you to verify that you own a particular account so that you can send transactions to the blockchain from that account.

Signed transactions - These are a type of transaction that must include the signature of an account sending an inbound request to execute some runtime call. The sender signs the transaction using their private key, demonstrating ownership of the assets being transferred.

Signed messages - Message signing is the action of signing a cryptographic message using a private key and its associated address to prove that you have access to the address. Wallets can verify these messages by checking the signature against the address to see if they correspond to each other. The result of a message signing is often called a signed message.

Transactions - Transactions in a blockchain are fundamental data units that represent a transfer of value or the execution of a specific action within the blockchain network. They are the building blocks of the blockchain and are used to record changes to the ledger securely and verifiable. There are three types of Ethereum network transactions:  transferring cryptocurrency from one account to another, deploying a smart contract, and interacting with a smart contract.
