Sandbox Environment
Full-featured test environment with pre-configured compliance corridors, sample data, and simulated validator consensus. Build and test settlement workflows without touching production.
The sandbox mirrors production infrastructure.
Test real settlement flows end to end. Swap the base URL when you go live - everything else stays the same.
Settlement API (TestNet)
Full REST API with auth, batching, idempotency, and receipt generation. Endpoints match production - swap the base URL when you go live.
Compliance Corridors
Pre-configured policy corridors for US-EU, US-SG, and intra-EU settlement. ATCE sanctions screening runs against test lists so you can validate full flows.
Simulated Consensus
3-of-5 validator quorum on TestNet. Consensus settles in under 2 seconds. Finality receipts are generated with real Ed25519 signatures.
Sample Data
Pre-loaded counterparties, test LEIs, sample IBAN/BBAN accounts, and token balances. Run settlement scenarios immediately without manual setup.
Block Explorer
TestNet block explorer with transaction search, state proofs, and receipt verification. Inspect every step of the settlement lifecycle.
Evidence Bundles
Cryptographic finality receipts generated on every sandbox settlement. Download JSON bundles with Merkle proofs, validator signatures, and compliance attestations.
Four steps from request to first settlement.
Request Credentials
Submit a sandbox request. You receive an API key pair (Ed25519) and a TestNet participant ID within one business day.
Configure Environment
Point your integration at the sandbox base URL. Set your API key in the Authorization header. The SDK handles auth, retry, and receipt parsing.
Submit a Settlement
Create a settlement instruction with originator and beneficiary details. The sandbox processes it through the full pipeline - compliance, binding, consensus, finality.
Verify the Receipt
Download the finality receipt and verify Ed25519 signatures. Includes settlement hash, validator attestations, compliance result, and binding confirmation.
Sandbox vs. Production
The sandbox mirrors production in every way that matters. Only the data and rate limits differ.
