Built on Camino Network

Blockchain-Backed Booking Infrastructure

Replace centralized OTA intermediaries with smart-contract escrow. Tour operators publish experiences on-chain, distributors book against atomic inventory, and funds settle automatically.

Create a Booking
$ curl -X POST inventory.test/api/v1/bookings \

Everything you need to decentralize bookings

One API replaces intermediary settlement, manual reconciliation, and opaque fee structures.

Smart Contract Escrow

Funds locked in EURe escrow on-chain. Automatic release after the cancellation deadline. No manual settlement, no spreadsheets.

Custodial Wallets (AWS KMS)

Every operator and distributor gets a wallet backed by AWS KMS hardware security modules. No seed phrases, no key management headaches.

Multi-Tenant API

Single API, isolated tenants. Each booking platform gets its own API keys, rate limits, and scoped data. No cross-contamination.

Fiat On/Off-Ramp

EUR to EURe via Monerium SEPA/IBAN. Operators withdraw to their bank account at any time. No crypto knowledge required.

Real-Time Chain Indexer

Event indexing under 5 seconds. Your database stays in sync with on-chain state. No polling, no stale reads.

Webhook Delivery

HMAC-SHA256 signed webhooks with automatic retry. Get notified of booking confirmations, cancellations, and settlements in real time.

Four steps to on-chain bookings

From API key to settled funds in four API calls.

01

Connect

Register your platform as a tenant. Get API keys in minutes. No blockchain setup needed.

02

Publish

Operators create experiences via the API. One call publishes inventory on-chain with pricing and capacity.

03

Book

Distributors book against atomic capacity. EURe escrow locks funds instantly on the smart contract.

04

Settle

After the cancellation window closes, funds release automatically to the operator. No manual action.

Why put booking inventory on a blockchain?

The travel industry runs on trust between strangers. Smart contracts replace that trust with code.

Atomic capacity

No double-bookings. Ever. On-chain state is the single source of truth for available inventory.

Trustless escrow

Funds governed by smart contracts, not intermediary goodwill. Release rules are transparent and immutable.

Transparent fees

3% protocol fee, enforced on-chain. No hidden charges, no surprise deductions at settlement.

Instant reconciliation

No end-of-month settlement spreadsheets. The chain is the ledger. Every transaction is auditable.

Cancellation policy enforcement

Refund rules coded in Solidity. No disputes about policy interpretation. The contract decides.

Frequently asked questions

Everything you need to know about integrating with Onvoy.

A REST API that manages travel booking inventory on the Camino Network blockchain. Tour operators publish experiences, distributors book them, and all escrow and settlement is handled by smart contracts. You interact through standard JSON endpoints — no blockchain tooling required.

No. We create custodial wallets automatically using AWS KMS hardware security modules. Your operators and distributors interact through a standard REST API. No seed phrases, no MetaMask, no blockchain knowledge required on their end.

EURe, a EUR-backed stablecoin issued by Monerium. 1 EURe always equals 1 EUR. Operators can convert EURe to EUR via SEPA bank transfer at any time through their Monerium IBAN.

Cancellation rules are encoded in Solidity smart contracts. The platform supports full-refund-before-deadline and non-refundable policies, both enforced automatically. A force-majeure override is available for admin use in exceptional circumstances.

A flat 3% protocol fee on each booking, deducted automatically at settlement. No setup fees, no monthly charges for the API itself. You pay only when bookings happen.

Camino Network C-Chain — an EVM-compatible blockchain purpose-built for the travel industry by the Chain4Travel foundation. Currently on Columbus testnet, with mainnet support planned.
