Glossary

Term	Definition
Account	In Okto, a user's account is a unified representation of all wallets (embedded and external) linked to their identity within client applications. It provides a consolidated view of a user's Web3 presence.
API Key	A unique identifier for your application within the Okto ecosystem. It is used to authenticate your application and authorize access to Okto services.
Authorization	The process of verifying if a user or application has the right permissions to access specific resources or perform actions. In Okto, this is managed using Okto Auth Tokens.
Auth Token	A secure token generated by combining user's login credentials, client API Key, and session data. Also known as Okto Auth Token.
Broadcasting Transactions	The process of submitting a signed transaction to the blockchain network to be included in a block.
Bulk Order ID	An identifier used when multiple orders are processed together for efficiency. A bulk order consists of multiple individual orders grouped for processing.
Chain Abstraction	The ability to interact with multiple blockchain networks without dealing with chain-specific details, simplifying development and user experience.
Chain Abstraction Embedded Wallet	Wallets that works seamlessly across all major blockchains with unified interface and social login access.
Client	The application or service integrating Okto SDK to provide seamless on-chain interactions to their users (previously referred to as Vendor).
Client ID	A unique identifier for your application within the Okto ecosystem.
Client Wallets	Treasury and Sponsor wallets that enable applications to execute on-chain operations and provide gasless transactions for users.
Connected Wallets	Refers to both external wallets that users connect to your application and embedded wallets created within your app. Okto provides a unified way to access and manage these wallets.
Cross-Chain Operations	Transactions or operations that involve multiple blockchain networks, facilitated by Okto's interoperability features.
Delegated Actions	Okto's session management system allowing users to grant temporary permissions to apps, enabling signless transactions within defined limits.
DTN (Decentralized Transaction Network)	Okto's execution layer that orchestrates multi-chain operations, translating user intents into atomic sub-transactions across blockchains.
DWN (Decentralized Wallet Network)	Network of secure, independent nodes using MPC technology to manage user wallets in a trust-minimized manner across all supported chains.
Embedded Wallets	Self-custodial wallets integrated directly into applications via Okto SDK, offering seamless onboarding through social logins with military-grade MPC security.
ERC-7683	The cross-chain intent standard that Okto implements for universal liquidity access and standardized cross-chain operations.
External Wallets	Cryptocurrency wallets managed by third-party providers (e.g., MetaMask, Phantom, WalletConnect). Users connect these existing wallets to your Okto application.
Filler/Solver	Specialized actors in the ULL that provide liquidity and execute cross-chain intents competitively for optimal pricing.
FST (Filler/Solver-Supported Tokens)	Tokens directly supported by the ULL's solver network for efficient cross-chain transfers without additional DEX routing.
Gasless Transactions	Transactions where users don't need native tokens for fees - they can pay in stablecoins or apps can sponsor fees entirely.
Intent/Intent-Driven	Okto's approach where users express desired outcomes (e.g., "swap USDC for BONK") rather than managing complex transaction steps.
Interoperability	Within Okto, refers to how embedded wallets can be shared across multiple client applications under the same Wallet Provider.
Job ID	A sub-task within an "order" in Okto. Each order, representing a blockchain action, may consist of multiple jobs to complete the overall process.
JWT (JSON Web Token)	A standard for securely transmitting information as a JSON object. Okto Auth Tokens are JWTs, encoding user and application identity for secure authorization.
MAW (Monthly Active Wallets)	Total number of unique wallets where a user performs at least one on-chain session in a Web3 application using the Okto SDK within a calendar month (30 days).
MPC (Multi-Party Computation)	Cryptographic technique used to secure wallet operations by distributing key management and signing processes across multiple parties, enhancing security and reducing single points of failure.
MFA (Multi-Factor Authentication)	An enhanced security measure for embedded wallets that requires users to verify their identity using multiple authentication factors before performing sensitive wallet actions.
Okto Chain	Specialized Layer-2 blockchain serving as the coordination and verification platform for the Okto ecosystem.
Okto SDK	Wallet infrastructure toolkit enabling developers to integrate embedded wallets, signless transactions, and gasless operations across multiple platforms.
Order	In Okto, an "order" represents a request or instruction to perform a specific action on the blockchain, such as token transfer or smart contract interaction. Orders have associated IDs and states.
Order ID	A unique identifier for a single "order" in Okto. Each order, representing a blockchain action, is assigned a unique Order ID for tracking and management.
Pathfinder	Okto Trade Service's Intelligent routing system that determines optimal execution paths for cross-chain transactions.
Policy Engine	A component of Okto's key management system that enforces predefined rules and permissions for actions within the Okto ecosystem, ensuring security and compliance.
Session Key	Key generated by the client for initial authentication processes, used to establish secure communication channels and initiate user sessions.
Session Management	System enabling users to grant temporary permissions to apps for signless transactions within defined limits.
Signless Transactions	Transactions executed without repeated signing popups, enabled through session management and delegated permissions.
Social Authentication	Login methods using familiar providers (Google, Email OTP, WhatsApp) instead of seed phrases, key to seamless onboarding.
Sponsor Wallet	Wallet holding funds to pay gas fees on behalf of users, enabling gasless transactions across all supported chains.
Sponsorship	Feature allowing clients to cover transaction fees for users, enhancing user experience by removing gas fee friction and simplifying onboarding to Web3 applications.
Sponsor Wallets	Wallets used by Client to cover transaction costs, especially gas fees, on behalf of users. Sponsor wallets enable users to transact without needing to hold native tokens for gas.
Tokens	In the context of blockchain, tokens represent cryptocurrencies and digital assets that users can manage within their Okto wallets. Okto supports various tokens on different chains.
Trade Service	API suite built on the ULL providing any-to-any token swaps across chains through simple intent-based requests.
Transaction Hash	A unique identifier generated by the blockchain when a transaction is executed and confirmed on the network. Transaction hashes are used to track and verify on-chain actions.
Treasury Wallet	Application's on-chain identity for executing direct operations and authorizing gas sponsorship for users.
TSS (Threshold Signature Scheme)	Cryptographic method where multiple parties must cooperate to sign transactions, part of Okto's MPC implementation.
ULL (Unified Liquidity Layer)	Okto's infrastructure aggregating liquidity across chains, enabling one-click cross-chain swaps through the ERC-7683 standard.
User	Any individual who uses a Client's application and, by extension, utilizes Okto's services to interact with Web3 functionalities.
Wallet Provider (WP)	Entity managing wallet infrastructure. Okto operates as a WP, providing EOA and AA wallet types with defined interoperability rules.
