From day one, Zerion API supports Arc, the stablecoin-native Layer-1 from Circle, giving developers production-ready wallet data on a chain built for real-world finance.

Arc is a stablecoin-native Layer-1 blockchain from Circle, purpose-built to move real value at scale. Fees are paid in USDC, transactions settle in under a second, and the chain integrates directly with Circle's full stack.

With Zerion API, developers building on Arc can access clean, indexed wallet data without running their own infrastructure.

What Zerion covers on Arc

Zerion API provides the same endpoints on Arc that developers already use across EVM chains and Solana:

Positions: Token balances for any Arc address.
Portfolio balance: Portfolio value over time, ready for charts and dashboards.
Transactions: Parsed, human-readable transaction history for reporting, reconciliation, and tax compliance.
Webhooks: Subscribe to new transactions on any Arc address for real-time notifications and event-driven workflows.

All endpoints follow Zerion's unified schema and a consistent data format across 40+ chains.

If you already use Zerion API for Ethereum or Solana, adding Arc takes minimal code changes.

Why this matters for Arc builders

Arc's design is optimized for moving real value, and that creates specific data needs:

Fees are denominated in USDC rather than a volatile gas token, so a user's gas, balances, and payment assets are all stablecoins.
Settlement is deterministic and final in under a second.
Because Arc uses Circle's stack, liquidity can move across chains like Ethereum and Solana through Arc as a settlement hub.

Zerion API abstracts all these complexities away and you can use Arc like a regular EVM chain.

You get normalized, enriched wallet data through a single REST call, fully interpreted and ready to plug into interfaces.
