July Zerion Alpha: Robinhood Chain brought the trenches back

July was a heavy shipping month: a new chain from block one, DeFi history in balance charts, and faster webhooks. Here's the rundown that we sent in our monthly newsletter, plus what's next.

Robinhood Chain: live from day one

Robinhood Chain mainnet launched on July 1. Zerion API covered it from block one, serving both RWAs and the newly re-ignited trenches. 

Apps already building on Zerion API pick up Robinhood Chain wallet data automatically. No code changes, the data flows through the same endpoints.

Zerion CLI levels up

The Zerion CLI got several updates: zerion login signs you in with your dashboard account over OAuth, multi-transaction signing is live, and new agent skills. For example, you can now use the CLI to consolidate all your tokens with the treasury management skill. 

You can even use the CLI to recover some long-forgotten tokens:

 Plus, with a new open-source skill, you can use the CLI to migrate your codebase from Zapper, Dune Sim, DeBank, Allium, or OneBalance automatically. 

Sandwich Trading: real-time onchain balances across 8 chains

Sandwich Trading runs its portfolio view on Zerion API. It shows the total value with chain and type breakdown, token positions, wallet balances, DeFi, and NFT positions across 8 chains.

Everything is done with one integration and no indexers to maintain.

More DeFi in Zerion API

If you’re using Zerion API endpoints for DeFi features, here are a couple of things you should know.

  • Historical DeFi in balance charts. Uniswap V2 and V3 LP positions and Morpho vault positions now flow into the wallet balance chart alongside token balances, when using only_complex or no_filter. Rolling out now.
  • Filters for pool, position, and vault filtering. Balance charts accept pool and position filters, not just token-level include and exclude.
  • Receipt tokens on DeFi positions. A new receipt field tells you which token balance represents a protocol position, so you can dedupe token balances against DeFi positions instead of double-counting. Live now on /positions.

Webhook updates

Zerion’s webhooks got even better. 

  • Faster delivery. We shaved roughly 800ms off end-to-end webhook delivery on Base mainnet by tightening our block-ingestion pipeline. More latency work is in progress.
  • Testnet transaction subscriptions. Webhooks now also work on testnets, starting with Base Sepolia.

Data quality improvement

Zerion API’s token spam scanning now runs across Solana assets the same way it does on EVM. And we cut the polling interval on Base to tighten data freshness.

Case study: Tria

Tria is a self-custodial neofinance app with a Visa card and 1,000+ tokens across Solana and EVM chains. Displaying a unified portfolio and cross-chain history would have meant running and maintaining a separate indexer per chain.

They wired up three endpoints instead (Portfolio, Positions, and Transactions) and are now doing millions of API calls a month, with tens of millions ahead.

Case study: El Dorado

El Dorado is a Latin American fintech super-app with over 1 million registered users and 5M+ transactions across 12 countries. Launching El Dorado Business on Tempo meant instant deposit confirmations on a tight deadline.

They added customer addresses to Zerion API webhooks and got parsed transactions right into their backend in real time. No issues since deployment.

Zerion Live: stablecoins, payments, and privacy

Are stablecoins the next real payment rail or just a well-funded narrative? Max from Privy and Juan Andreau, CTO of El Dorado, joined us to get into payments, privacy, and the $1.79T question.

Coming soon

Here’s what’s coming next to Zerion API.

  • Tokenized asset labeling. Clear asset classes for tokenized stocks, commodities, stablecoins, and treasuries in positions and transactions, so RWAs and stablecoins are distinguishable from ordinary tokens.
  • Pay as you go with fixed caps. Go past your plan quota with a hard spend cap you set yourself, managed from the dashboard.
  • More chains, based on your requests. Tell us which ones you need.

Improved docs

The docs now have an open-source agent skill that migrates a codebase for you and all the details on Zerion Streams, our managed Kafka feeds for real-time transactions and prices.
