Value Transfer API

The Value Transfer API is the canonical interface for value movement in crypto. One API replaces multiple bridge and swap integrations, giving you access to OFTs, Stargate, Aori, CCTP, and multihop flows through a single endpoint.

The problem​

Moving value across blockchains today is fragmented. Developers integrate multiple bridges, swap protocols, and settlement systems to offer users seamless cross-chain experiences. This creates friction for wallets, DeFi apps, exchanges, and fintechs that need a single, predictable way to move assets anywhere in crypto.

LayerZero already powers much of this infrastructure through OFTs, Stargate, and Aori. The Value Transfer API abstracts that complexity into one programmable interface to move value of any kind—stablecoins, OFTs, native tokens, wrapped assets—across any chain.

What the API provides​

  • A single integration point that replaces multiple bridge and swap connections. Access 450+ tokens across 150+ chains without managing separate integrations for OFT, Stargate, CCTP, or Aori.

  • Production-ready infrastructure with a quote-then-execute pattern, comprehensive error handling, and end-to-end status tracking.

  • Unified routing that evaluates all available paths - OFT transfers, Stargate pools, CCTP, intent-based swaps and returns optimal routes based on speed, cost, and liquidity.

How it works​

The API follows a quote-then-execute pattern:

  1. Request a quote: Submit source and destination details to receive available transfer routes
  2. Execute user steps: Sign and submit the transactions or signatures returned in the quote
  3. Track status: Poll the status endpoint until the transfer completes

Supported route types​

The API automatically selects the optimal route based on your transfer parameters:

TypeDescription
OFTOFT Standard transfers
STARGATE_V2_TAXIStargate V2 instant transfers
STARGATE_V2_BUSStargate V2 batched transfers
CCTPCircle CCTP for native USDC
AORIIntent-based swaps via Aori

Learn more about route protocols​

  • Stargate: Unified liquidity pools enabling native asset transfers with instant guaranteed finality
  • OFT (Omnichain Fungible Token): Token standard for seamless cross-chain token transfers without wrapped assets
  • CCTP (Cross-Chain Transfer Protocol): Circle's native USDC cross-chain transfer protocol with burn-and-mint mechanism
  • Aori: Intent-based trading protocol enabling optimal cross-chain swaps through a decentralized order book

Key capabilities​

  • Transparent pricing: Upfront quotes with fees, slippage, and USD valuations before execution
  • End-to-end tracking: Monitor transfer status from initiation to delivery
  • Multi-VM support: Transfer between EVM, Solana, Aptos, TON, and other chains
  • Source-chain gas only: Users pay gas once; destination chain fees are handled through LayerZero messaging
  • Intelligent routing: The API evaluates transfer speed, fees, and liquidity to return optimal routes

Use cases​

Wallets​

Embed cross-chain swaps and bridges without managing multiple integrations. Provide users with transparent fee breakdowns and real-time transfer tracking.

Exchanges and on/off ramps​

Accept deposits from any chain and credit users on your settlement chain. Enable cross-chain withdrawals without manual reconciliation.

DeFi applications​

Enable one-click deposits from any chain into your protocol. Abstract away the complexity of liquidity fragmentation.

Fintechs and neobanks​

Build crypto transfer features using a single, well-documented API. Monetize transfers with configurable fee structures.

Authentication​

Some endpoints require an API key passed in the x-api-key header. Public endpoints like /chains and /tokens can be accessed without authentication.


  curl -X POST "https://transfer.layerzero-api.com/v1/quotes" \
    -H "x-api-key: YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{"srcChainKey": "base", ...}'
