DALP concepts

Find the DALP concept page that defines each part of the digital asset lifecycle: settlement, compliance, custody, records, and operations.

DALP is SettleMint's Digital Asset Lifecycle Platform for issuing, governing, settling, and servicing regulated tokenised assets. The concept library has ten groups, in the order an institution meets them: the platform, modelling assets, issuing and markets, settlement, Compliance & Identity, custody and signing, records and evidence, events out, operating, and API and integration.

Each concept page defines its subject and explains its controls and limits. Some cards link to platform and API reference pages, which hold the detail for those subjects.

Ten stations, in the order an institution meets them.The concept library is arranged as one path with ten stations, read left to right along each row, wrapping to the next row after every three stations. The first station, and the recommended entry point, is the platform: what you deploy, and how it is divided. The second is modelling assets: what an instrument is, from template to token. The third is issuing and markets: how assets reach investors, and where they trade. The fourth is settlement: how value moves, and what makes it final. The fifth is Compliance & Identity: who may hold it, and what gates a transfer. The sixth is custody and signing: who holds the keys, and who approves signing. The seventh is records and evidence: what is recorded, and what an auditor reads. The eighth is events out: what the platform reports to your systems. The ninth is operating: how you run the Console and the portal, and read the platform's health. The tenth is API and integration: the contract every request follows. The order is the order an institution meets these questions, not a required reading sequence. Every page stands on its own.Ten stations, in the order an institution meets them.The same figure as the desktop variant, drawn portrait for phone widths: the ten stations of the concept library stack top to bottom, from the platform you deploy, through modelling assets, issuing and markets, settlement, Compliance & Identity, custody and signing, records and evidence, events out, and operating, down to API and integration. The order is the order an institution meets these questions, not a required reading sequence. Every page stands on its own.

Read Where to start next for the fastest way in, based on why you are here.

Where to start

Four entry points cover most arrivals. If none of them fits, start with the platform, as the figure does.

To work out what DALP is and where it runs, start at DALP Instance, then read Platform Architecture for how the platform divides responsibility across named systems.

For issuing or servicing an instrument, Asset Lifecycle covers the whole arc, and Instrument Templates explains how one product shape is defined once and reused.

For compliance, audit, or day-to-day operating, Compliance Policy covers what gates a transfer, Audit Trail covers the off-chain record of who did what, and Platform Health covers how you read the platform's own condition.

Integration work starts in the API reference. API Key covers how a request authenticates, and Idempotent Write covers the one rule that keeps a retried instruction from settling twice.
