Hyphen Review 2026: Biconomy's Cross-Chain API

Our verdict on Hyphen
5.5/10Hyphen may suit developers who want to add cross-chain transfers between EVM networks and Layer 2s through an API. Its clearest strength is the integration-focused approach and support for several major networks. The main caveat is that current product availability, fees, route details, and the bridge's security design are not clearly documented. Treat it as a product to investigate rather than a fully assessed transfer option until you can review current documentation and audit reports.

What is Hyphen?
Hyphen is Biconomy's cross-chain transfer service, described as a set of APIs for offering value transfers between EVM chains and Layer 2 networks. It is intended to help applications support transfers between networks and onboard users from Layer 1 to Layer 2.
Biconomy's current platform presents itself as a broader execution layer for Web3, with cross-chain transactions, gas sponsorship, and smart sessions. The exact relationship between those platform features and Hyphen is not explained, and the current availability of Hyphen as a distinct product is unclear.
The listed networks are Ethereum, Polygon, Arbitrum, BNB Chain, Avalanche, and Optimism. Fees, current route availability, transfer limits, and the underlying bridge design are not published in the available product details.
How Hyphen works
Hyphen is described as an API service that lets applications offer transfers between EVM chains and Layer 2 networks. A user or application requests a transfer from a source network to a destination network, while Hyphen's integration layer is intended to handle the cross-chain transaction process. The detailed routing, settlement, and custody mechanisms are not published in the product details available here.
Cross-chain transfers involve transactions on separate networks, so users should confirm the selected route and destination before proceeding. Biconomy describes Hyphen as aiming to make these transfers fast, but does not publish a guaranteed completion time or a complete list of current routes.

Pros and cons
What we like
- API-based approach can let developers build cross-chain transfers into an application.
- Designed for transfers between EVM networks and Layer 2s.
- The listed network set includes several major EVM chains and scaling networks.
Watch out for
- Hyphen's current availability and supported routes are not clearly explained on Biconomy's homepage.
- Fees and transfer limits are not published.
- The bridge's specific security and custody design is not described.

Hyphen fees
Hyphen's transfer fees, limits, and pricing structure are not published in the available product details. Check the quote shown before a transfer or the current integration documentation for any service charges; network gas costs may apply separately.
Is Hyphen safe?
Biconomy lists two audits, but the audit names, scope, and findings are not specified in the available product details. Hyphen's specific custody model, routing design, and recovery process are also not published, making it difficult to assess the bridge's full security assumptions.
Cross-chain transfers carry smart-contract and network risks, and a mistake in the destination network or address may be difficult to reverse. Check current audit reports and product documentation before transferring funds.
