Building with the Phyntec SDK

The Phyntec SDK is the primary interface for developers building tokenization systems on our infrastructure. It provides a TypeScript-first API for defining token configurations, selecting compliance modules, generating smart contract systems, and deploying them across multiple EVM-compatible chains. The SDK abstracts the complexity of diamond proxy patterns, storage layout management, and facet wiring into a declarative configuration model that reads like a specification rather than low-level bytecode manipulation.

At its core, the SDK operates on manifests — JSON documents that describe the desired state of a smart contract system. A manifest lists the packages to be installed, their versions, their configuration parameters, and the target chain. When you run the deploy command, the SDK resolves dependencies, checks compatibility, generates the diamondCut calldata, and executes the transaction. If you are upgrading an existing system, the SDK computes the minimal diff between the current and desired states, ensuring that only the changed facets are replaced.

The SDK also includes utilities for testing, monitoring, and interacting with deployed systems. The test runner spins up a local Hardhat or Anvil node, deploys the manifest, and executes a suite of generated and custom tests. The monitoring module watches on-chain events and syncs them to a local database for querying. And the interaction module provides typed wrappers for every function exposed by the diamond, so developers get full autocomplete and type safety when building front-end integrations or automation scripts.
