Glossary
Definitions of key DALP architecture terms, token standards, identity concepts, operating components, and settlement primitives.
DALP architecture terms map to concrete product boundaries: tokens, identities, compliance rules, settlement flows, execution components, and EVM chain connectivity. Use this glossary when a term appears in an architecture page and you need the exact platform meaning.
Related pages: Architecture map, System context, ERC-3643 compliance standard, and SMART Protocol integration (ERC-3643).
Start with the term table when you need a definition. Use the standards table when you need to map a DALP concept to an Ethereum or identity standard. Follow the next-step links when you need the architecture page that explains the term in context.
| Term | Definition |
|---|
| DALP | Digital Asset Lifecycle Platform. SettleMint's platform for issuing, managing, and servicing tokenized financial instruments across their full lifecycle. |
| SMART Protocol | SettleMint Adaptable Regulated Token. The protocol framework for regulated token behavior, compliance modules, and identity interfaces based on ERC-3643. |
| ERC-3643 | Ethereum standard for regulated tokens with conditional transfers based on investor eligibility and identity verification. DALP uses ERC-3643 concepts through SMART Protocol asset contracts. |
| Asset type | A base deployable asset type such as bond, equity, fund, stablecoin, deposit, real-estate, or precious-metal. DALP uses the type to route asset creation to the matching factory and validation rules. |
| Asset class | A higher-level product grouping used by the asset catalogue and templates. System asset classes include fixed-income, equity, funds, cash, real-assets, and structured. |
| Asset factory type ID | The on-chain factory identifier used when DALP deploys an asset. Most IDs match asset types, and dalp-asset is a synthetic factory type for generic asset creation rather than a standalone asset class. |
| Factory pattern | Deployment pattern where factory contracts create new asset, addon, or infrastructure contract instances from approved configuration. Factories are registered so DALP can deploy assets consistently. |
| Denomination asset | The settlement currency or token configured for an asset's financial operations, such as distributions, offerings, yield claims, or redemptions. |
| Token feature | Runtime-configurable token capability registered through the Configurable extension. Features can be added after deployment when the asset policy and deployed contracts support them. |
| Addon | Operational contract capability that extends assets beyond the core SMART Protocol. Addons are registered through the Addon Registry and include Airdrop, Vault, XvP Settlement, Token Sale (DAIO), and Yield. |
| Term | Definition |
|---|
| OnchainID | On-chain identity framework implementing ERC-734 key management and ERC-735 claim management. OnchainID stores verifiable claims about users and entities. |
| Identity Registry | Per-system contract that maps wallet addresses to OnchainID identity contracts. The registry manages verification status and supports wallet recovery workflows. |
| Trusted Issuer | An approved issuer of verifiable claims for specific claim topics. Trusted issuers are registered in the Trusted Issuers Registry, and more than one issuer can cover the same topic. |
| Claim Topic | A category of verifiable attestation, such as KYC status, nationality, accreditation, or another eligibility rule. Tokens reference claim topics to express required participant claims. |
| Compliance Module | A pluggable on-chain rule evaluated during regulated token operations. Examples include country allow or block lists, identity verification, transfer limits, and time-based lockups. Multiple modules compose into an asset's compliance policy. |
| Term | Definition |
|---|
| Key Guardian | Secure cryptographic key storage component. Key Guardian abstracts custody backends such as local encrypted keys, DFNS MPC wallets, Fireblocks vaults, and hardware security modules. |
| Transaction Signer | Execution component that prepares transactions, estimates gas, assigns nonces, delegates signing to the custody provider, and manages broadcast and confirmation. |
| Execution Engine | Durable workflow layer for long-running platform operations such as signing, broadcasting, retrying, and reconciling blockchain outcomes. |
| Virtual Object | A keyed durable state machine in the Execution Engine. A virtual object preserves workflow state across process restarts for operations such as signing and multi-step execution. |
| Dead Letter Queue | Holding area for operations that exhaust retry attempts in the Execution Engine. Operators investigate these items before retrying or closing them. |
| Chain Indexer | Service that listens to on-chain events from SMART Protocol contracts, translates them into structured data, and persists them to the application database. |
| Chain Gateway | Multi-network connectivity layer for EVM RPC access. Chain Gateway abstracts network-specific details such as gas models and confirmation depth behind DALP's chain access layer. |
| Feeds System | Market data infrastructure that provides price and FX rate feeds through a central FeedsDirectory. The feeds system is Chainlink-compatible and supports global and token-specific feeds. |
| Term | Definition |
|---|
| XvP Settlement | Cross-value proposition settlement addon for coordinating token exchanges between parties. DALP uses the primitive for delivery-versus-payment and payment-versus-payment token flows. Configured local legs complete together or the exchange does not complete. |
| DAIO | Digital Asset Initial Offering. Primary distribution mechanism for moving newly issued assets to verified investors with settlement, lock-up enforcement, and soft-cap refund mechanics. |
| Airdrop | Token distribution addon that delivers tokens to recipient addresses according to a configured strategy. Airdrop integrates with the compliance layer for eligibility checks. |
| Vault | Multi-signature treasury management addon for holding and governing settlement currency or digital assets with configurable approval thresholds. |
| Standard | Full name | Usage in DALP |
|---|
| ERC-20 | Fungible token standard | Base token compatibility for SMART tokens |
| ERC-165 | Interface detection | Programmatic capability queries on SMART tokens |
| ERC-734 | Key management | On-chain identity key management in OnchainID |
| ERC-735 | Claim management | Verifiable claims on identity contracts |
| ERC-2771 | Meta-transactions | Gasless transaction support through trusted forwarders |
| ERC-3643 | Regulated security tokens | Foundation for SMART Protocol compliance architecture |
