Relay is onchain payments infrastructure that lets payment service providers add universal onchain acceptance and payouts through a single integration. Consumers and businesses can spend any onchain currency they hold and Relay routes, converts, and settles to your chosen asset and chain.

## Use Cases

### Pay-ins or Commerce

Accept funds in any asset on any of 85+ chains — or the same chain — and receive your settlement asset (e.g., USDC on Base or Solana). Two integration paths:

**Connected or embedded wallet payments** — Use the standard [quote and deposit flow](https://docs.relay.link/references/api/get-quote-v2) when your user connects a wallet. Quote, deposit, fill. Deposits are optionally [gasless](https://docs.relay.link/features/gasless-execution), with [fixed or market rates](https://docs.relay.link/features/price-stabilization).

**Deposit addresses** — Generate one [deposit address](https://docs.relay.link/features/deposit-addresses) per order for wallet-less acceptance. Anything sent to it is routed and converted to your settlement asset automatically, with no frontend integration on the payer side. Deposit addresses also power QR and scan-to-pay for cross-chain acceptance, and are extremely valuable for centralized exchange payments.

### Disbursements

Run pay-ins in reverse to send funds out — marketplace seller payouts, creator and worker disbursements, and cross-border payout — to any chain and asset from your settlement balance, through the same integration.

## Compliance & Screening

Relay screens every transaction in real time against multiple independent blockchain-analytics providers and a continuously maintained internal blocklist, enforcing OFAC and other global sanctions requirements. Screening covers every party to a transfer — sender, recipient, and fee recipient, plus the depositing wallet on deposit-address flows — not just a single address. A match on any party blocks the quote and fill. See [Compliance](https://docs.relay.link/security/compliance) for details.

## Features

**[Exact-output settlement](https://docs.relay.link/references/api/api_core_concepts/trade-types)** — Specify the exact amount you need to receive; Relay sizes the input. No slippage, no shortfalls.

**[Price stabilization](https://docs.relay.link/features/price-stabilization)** — Lock a fixed rate (e.g. 1:1) on stablecoin pairs, or sponsor fees so the user receives the full market-rate output. Removes exchange rate surprises from settlement.

**[Gasless execution](https://docs.relay.link/features/gasless-execution)** — Your users transact without spending gas directly. This can be used for Relay deposits or more generally for any onchain gasless execution.

**[Fee sponsorship](https://docs.relay.link/features/fee-sponsorship)** — Pay or subsidize gas or spreads on your users’ behalf, and let them pay in the asset they already hold.

**[App fees](https://docs.relay.link/features/app-fees)** — Attach your own fee to any flow and collect it at settlement, automatically settled in USDC on Base.

**[MEV protection](https://docs.relay.link/security/mev-protection)** — Swaps are routed for best execution.

**[Webhooks and tracking](https://docs.relay.link/references/api/api_guides/webhooks)** — Lifecycle events are pushed to your backend (HMAC-signed), and every payment carries a `requestId` for reconciliation.

**Reliability** — 99.9%+ fill success with sub-3-second settlement on supported routes.

## Pricing

Relay’s cost is transparent in every quote. The `expandedPriceImpact` object breaks each payment into its execution, swap, and Relay fee components, plus any app fee you add — so your finance team can model unit economics exactly. Integrators above a volume threshold qualify for a revenue share on the Relay fee. See [Fee Structure](https://docs.relay.link/references/api/api_core_concepts/fees).

## Security

Relay’s contracts are independently audited, and the protocol runs an ongoing bug bounty. Review the [Contract Audits](https://docs.relay.link/security/contract-audits) and [Bug Bounty](https://docs.relay.link/security/bounties) before you integrate.

## Get Started

Add cross-chain pay-ins and disbursements to your platform through a single integration. The [Quote API](https://docs.relay.link/references/api/get-quote-v2) is the core endpoint behind both flows.

- **[Quickstart Guide](https://docs.relay.link/references/api/quickstart)** — make your first cross-chain transaction.
- **[Quote API reference](https://docs.relay.link/references/api/get-quote-v2)** — the core endpoint behind pay-ins and disbursements.
- **[Deposit Addresses](https://docs.relay.link/features/deposit-addresses)** — wallet-less acceptance.
