Onboard primary-source snapshot

Fetched: 2026-04-26 UTC

1) Core identity and ecosystem split

Source: https://docs.onboard.xyz/introduction.md Source: https://docs.onboard.xyz/the-protocol.md

Selected excerpts from the docs:

A global p2p exchange protocol that allows anyone, anywhere to get onchain.

Onboard Protocol is a non-custodial peer-to-peer (P2P) protocol that enables secure exchange of assets in a trustless and globally accessible manner.

Via Onboard, users can trade assets using their preferred self-custody crypto wallet, without the need for a centralized custodian to hold funds.

Additional signals from the docs:

  • The docs clearly separate Onboard Protocol, Onboard Exchange, and Onboard Connect, which helps avoid flattening the project into a single wallet app or single API
  • The official framing is strongly adoption-oriented, but the protocol and exchange docs provide enough operational detail to make the system concrete
  • This appears to be infrastructure for crypto-fiat exchange flows, especially for apps that want local payment rails without centralized custody of crypto assets

2) Escrow-centric technical model

Source: https://docs.onboard.xyz/the-protocol.md Source: https://docs.onboard.xyz/protocol-concepts/architecture.md

Selected excerpts from the docs:

The protocol’s core innovation is a Smart Contract Escrow Account, which securely locks assets during a trade, and only releases these assets after the explicit approval of both buyer and seller, or in cases of disputes, a mediator.

The SCEA is a SmartContract that lives on the Ethereum Virtual Machine and stores records of escrow data, and also holds both native and ERC-20 tokens.

Additional signals from the docs:

  • The architecture page describes owner, initiator, mediator, escrow, and lock-balance roles explicitly, which is useful for understanding the trust and dispute boundaries
  • The protocol is described as deployable on EVM-compatible chains, rather than as a single-chain application
  • The mediator role is important: this is not a pure AMM or simple OTC directory, but an escrow-and-dispute coordination system

3) Exchange flow and local payment rails

Source: https://docs.onboard.xyz/onboard-exchange/how-exchange-works.md Source: https://docs.onboard.xyz/onboard-exchange/supported-currencies-payment-channels.md

Selected excerpts from the docs:

Onboard Exchange enables seamless fiat-to-crypto (onramp) and crypto-to-fiat (offramp) transactions.

Compatible with any EVM-compatible dApps or wallets, Exchange allows anyone get onchain in less than 3 minutes, supporting micro-transactions of as little as $0.5 at near zero-fees.

Additional signals from the docs:

  • The example flows show a real P2P operating model: select an offer, lock crypto in escrow, move fiat over a local rail, then release escrow after confirmation
  • The supported-currencies page exposes regional rails like Nigerian Naira, Kenyan Shillings, Ghanaian Cedis, Mauritian Rupees, Ugandan Shillings, bank transfers, and M-PESA-style channels
  • This regional payment-channel detail makes Onboard more legible as emerging-markets exchange infrastructure rather than a generic wallet feature

4) Integration surface for third-party apps

Source: https://docs.onboard.xyz/onboard-exchange/connect/overview.md Source: https://docs.onboard.xyz/llms.txt

Selected excerpts from the docs:

Build a low-code or native on/off-ramp flow hosted on Onboard

Onboard Connect provides two integration options for enabling on and off-ramp functionality in your Web3 wallets and dApps.

Additional signals from the docs:

  • The docs expose both hosted low-code integrations and native APIs, which suggests Onboard is selling a platform surface in addition to its own exchange
  • Claimed features include 100+ local payment methods, no-KYC and KYC trade modes, best-offer matching, webhooks, and trade APIs
  • The published llms.txt plus OpenAPI references make this a strong docs-first project even without a traditional whitepaper PDF

5) Contract and source-of-truth posture

Source: https://docs.onboard.xyz/contracts/list-of-contracts.md Source: https://docs.onboard.xyz/llms.txt Source: https://github.com/OnboardGlobal

Selected excerpts/signals from the docs:

List of Contracts

Factory Contract

Escrow Contract

Lookup Contract

Additional signals from the public materials:

  • The contract-list page is conceptual and does not publish concrete addresses in the version reviewed here, so the docs are stronger than the onchain registry surface in this pass
  • The docs themselves link to a public GitHub organization, reinforcing that the project presents as open-source protocol infrastructure
  • The best primary sources in this pass were the docs portal, protocol and exchange pages, integration docs, llms.txt, and contract architecture pages

Notes

  • This pass did not locate a canonical standalone whitepaper from official Onboard materials.
  • Onboard appears best cataloged as crypto-fiat on/off-ramp protocol and escrow-based exchange infrastructure, not merely as a wallet app.
  • The strongest signal came from the combination of protocol docs, exchange flow docs, regional payment-channel matrices, and integration/API docs.
