Deposits for onchain apps, simplified.

Halliday is the end-to-end deposit platform for onchain apps: one embedded widget and API that unifies fiat onramps and offramps (cards, bank transfers, Apple Pay, Google Pay, PayPal), centralized exchange balances, and cross-chain stablecoin and crypto deposits, so users fund an account in one click and receive the right token on the right chain, typically in under a minute. Halliday is non-custodial by design and never holds user funds.

Halliday powers deposit flows for trading platforms first: perp DEXs, prediction markets, and meta-trading apps that trade across venues. It also onboards users to L1, L2, and appchain native tokens, and powers stablecoin funding for RWA platforms, neobanks, and FinTechs, plus wallets, DeFi protocols, and consumer crypto apps.

Yes, and more. Halliday routes fiat onramps across global providers such as Coinbase Onramp, Stripe, Binance, Banxa, Ramp, Transak, MoonPay (and more), and also accepts deposits from centralized exchange accounts and from crypto held in an EOA on any chain. Everything is covered by one integration and one agreement, with automatic failover and retries across providers.

A single onramp covers one payment method in some geographies and usually redirects users away from your app. Halliday embeds every funding method inside your product, lets verified users skip repeat KYC, chooses the best route by geography, payment method, and price, and delivers the final token on the destination chain automatically.

No. Each payment starts at a deposit address that only the owner address specified in the API call can control via signatures. Once a payment is funded, Halliday's routing network executes any required bridging and swaps onchain and the user receives the output token in their own wallet. If a payment stalls, the owner can recover or retry it.

Halliday supports deposits to any token on any supported chain, including EVM and non-EVM networks. New tokens on supported chains can be added quickly by the Halliday team, and new chains can be onboarded. The current list is in the docs.

Yes. Users can deposit USDC, USDT, or any other supported stablecoin from any wallet on any supported chain, and Halliday delivers the token your app expects on your settlement chain. Stablecoins held on a centralized exchange work the same way. Crypto deposits need no KYC.

Yes. Users can pay from any wallet on any supported chain. Halliday quotes routes across bridges including Circle CCTP and Stargate (among others) and across DEXs, ranks them by highest output and lowest latency, and executes the bridge and swap steps automatically so the user receives the destination token in one interaction.

Yes. Any centralized exchange that can send major tokens such as USDC to an external address works with Halliday. Supported tokens and chains are listed in the docs.

Yes. The same widget and API handle withdrawals. A balance can be withdrawn as tokens onchain with a normal transfer to an address you define, swapped and bridged to a different token on a different chain and delivered to any address, or offramped to fiat in the user's bank account through supported offramp providers.

Yes. Users can offramp a crypto or stablecoin balance to a bank account through supported offramp providers, inside your app. Any swap or bridge needed to reach the provider's accepted asset runs automatically. Payout methods and availability depend on the user's location and the provider.

Halliday supports bank deposits from local and multi-currency accounts over ACH, wire, and SWIFT; local payment rails including SEPA (EU), Faster Payments (UK), PIX (Brazil), and SPEI (Mexico); and real-time payment networks including UPI (India), KFTC Open Banking (South Korea), and FAST (Turkey). Each user sees the rails available in their location.

Pricing is usage-based and charged per successful deposit. Pay as You Go has no commitment, and you can go live immediately with a free API key. Custom contracts add commitment discounts and forward-deployed support for higher volumes. Contact sales for exact rates.

Halliday operates globally. Crypto deposits are supported in every jurisdiction outside Halliday's exclusion list, and fiat onramp providers are shown to each user based on their location and available payment methods.
