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.
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).
Build directly on Layer 1
Deploy on the Haidrun Network without third-party API overhead — full access to the settlement and execution engine.
EVM-compatible contracts
Deploy Solidity contracts using standard tooling, with parallel, deterministic execution.
Specs from the API
Documentation generated from the API itself, so references stay in sync with the running implementation.
From credentials to confirmed transaction in three steps
Get credentials
Authenticate with OAuth 2.0 and receive your access token.
Call the API
Submit a transaction or query wallets over REST.
Confirm
Receive a webhook with the transaction hash and finality in under 500 ms.
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 /v1/stablecoins/{id}/mint Authorization: Bearer ••• { "amount": "1000000", "to": "0x…", "reference": "treasury-01" } → 201 Created { "status": "settled", "tx": "0x…" }
