Built API-first

Integrate in weeks with industry-standard REST APIs — or build directly on Layer 1 with our SDK and EVM-compatible smart contracts. OAuth 2.0 security, OpenAPI specs and deterministic execution.

What you get
REST API

Clean, versioned endpoints

Secured with OAuth 2.0 + JWT and TLS 1.3 / mTLS. Core endpoints: authentication, transactions, KYC/KYB, wallets and complaints (MiCA Art. 71).

SDK

Build directly on Layer 1

Deploy on the Haidrun Network without third-party API overhead — full access to the settlement and execution engine.

HVM / Solidity

EVM-compatible contracts

Deploy Solidity contracts using standard tooling, with parallel, deterministic execution.

OpenAPI

Specs from the API

Documentation generated from the API itself, so references stay in sync with the running implementation.

Quickstart

From credentials to confirmed transaction in three steps

1

Get credentials

Authenticate with OAuth 2.0 and receive your access token.

2

Call the API

Submit a transaction or query wallets over REST.

3

Confirm

Receive a webhook with the transaction hash and finality in under 500 ms.

Illustrative

Mint a stablecoin with a single call.

Issue against your reserves with a REST call — signing keys stay inside FIPS 140-3 Level 3 HSMs, settlement is deterministic and final.

Illustrative only — final API reference lives in the docs.

POST · api.haidrun.com
POST /v1/stablecoins/{id}/mint
