Onboard Connect & Merchant API — Crypto On/Off-Ramp Infrastructure

Onboard provides battle-tested B2B infrastructure enabling Web3 wallets, dApps, fintech platforms, and high-volume merchants to embed crypto on/off-ramp functionality via SDK, API, or hosted redirect.

Product Overview

Built on the Onboard Protocol — a suite of open-source, EVM-compatible smart contracts — the platform powers fiat-to-crypto and crypto-to-fiat conversion through a peer-to-peer exchange model with 2-minute settlement finality. Onboard is registered as a money services business with FINTRAC (Canada), FinCEN (USA), and as a VASP in Poland, providing out-of-the-box regulatory compliance across multiple jurisdictions.

Key Features

• Over 100 local payment methods across 13+ fiat currencies including mobile money and bank transfers
• Both no-KYC trades (with limits) and full KYC-enabled trades
• Low-code hosted redirect for rapid deployment or fully native API for custom UX
• Multilingual support: English, Portuguese, and Spanish
• Supported networks: Base, BSC, Polygon, Arbitrum, Celo, Ethereum, TRON, and Optimism
• Supported assets: USDT, USDC, and additional tokens
• Merchant API for high-volume programmatic buy/sell order management
• Trustless escrow smart contracts providing transparent, auditable settlement

Use Cases

Onboard Connect is used by Web3 wallet providers, dApp developers, and fintech platforms seeking to add compliant on/off-ramp rails without building liquidity infrastructure from scratch. The Merchant API serves exchanges, remittance platforms, and digital businesses operating at scale in emerging markets across Africa, Latin America, and Asia. Production integrations include Coinbase Wallet (50+ markets), IDRx, and Lisk. Backed by Coinbase Ventures.
