Supported Networks and Currencies: Powered by Relay, Updated Automatically

March 15, 2026 — OrcaRail uses Relay Link for payments and cross-chain bridging. As a result, we support the same networks and currencies that Relay supports—and they’re integrated automatically. No hardcoded list to maintain; when Relay adds or updates chains and tokens, our system picks them up.

Where the List Comes From​

We don’t maintain a separate, hand-curated list of supported networks and tokens. Instead:

  • Networks are synced from Relay’s Chains API (api.relay.link/chains for mainnet, plus testnets). Our seed process builds network records from Relay’s chain data—including EVM, Bitcoin, and Solana chain types where Relay supports them.
  • Currencies and tokens are synced from Relay’s Currencies v2 API (get-currencies-v2). Tokens are upserted per network, so each chain gets the right set of payables and bridgeable assets.

When Relay adds a new chain or currency, our seed/update process brings it in. You get automatic alignment with Relay’s coverage without extra integration work on your side.

What “Support” Means​

Payments and (where applicable) bridging follow Relay’s supported routes. Relay currently supports 69+ blockchain networks across:

  • EVM chains (Ethereum, Base, Polygon, Arbitrum, Optimism, and many more)
  • Bitcoin
  • Solana (SVM)
  • Tron

Per chain, token support can be "All" (tokens where Solver or DEX liquidity exists) or "Limited" (only tokens listed with supportsBridging: true). For the canonical picture of routes and token support, see Relay’s docs:

How to See What OrcaRail Supports​

Use our API to get the current set of networks and tokens available in OrcaRail:

  • Networks: GET /payments/networks — list all supported networks (optionally filter with ?active=true).
  • Tokens per network: GET /payments/networks/:id/tokens — list tokens for a given network (use the network id from the list above).
  • Fiat/display currencies: GET /price/currencies — list supported fiat currencies for pricing and quotes.

Full details are in the Payments API – List Networks / List Tokens and Price API – List Currencies docs.

Supported networks and currencies at OrcaRail are powered by Relay and updated automatically—one integration, many chains.
