Arbitrum Indexing, Now Self-Serve

Six Arbitrum templates, a self-serve console, and onchain payment in USDC. Everything we shipped for Arbitrum, in one place.

Arbitrum One produces around 345,000 blocks a day. Getting a specific slice of that into your own database has usually meant running an indexer or maintaining a subgraph.

Over the past six months, supported by an Arbitrum Foundation DevTooling grant, we made that self-serve. Here is what shipped.

Templates

Six Arbitrum templates are live in the console, each with a working transformation and deploy config you can edit before deploying:

Template	What it captures	Delivery
Arbitrum DEX Swaps	Swap events on Uniswap V3 and Camelot/Algebra pools	Postgres
Arbitrum Lending Events	Aave V3 and Radiant lending events	Postgres
Arbitrum Bridge Flows	Stargate V1 pool swaps and native ETH withdrawals	Postgres
Arbitrum USDC / USDT Payments	Stablecoin transfers for settlement and treasury flows	Postgres
Large Transfer Alerts	Webhook when a USDC or USDT transfer crosses a threshold	Webhook
Large Bridge Value Alerts	Webhook when bridge flows exceed 10k USDC/USDT or 5 ETH	Webhook

Each one was validated against live Arbitrum blocks before release.

A console you can deploy from

Pick a template, preview the transformation against a real block, point it at Postgres or a webhook, and deploy. Browsing templates and testing transformations needs no account. You sign in when you want to deploy and manage something that stays running.

Deployed pipelines are listed, paused, and removed from the same place.

Onchain payments

New accounts get 10,000 free blocks. After that you can top up in USDC or ETH on Arbitrum, and the payment credits your account balance directly. No invoice, no card.

Coverage

Arbitrum One is indexed in full, with no sampling, at a 500ms poll interval. Delivery latency from block confirmation is consistently under a second. Arbitrum Sepolia runs at the same cadence.

Current chain state is public: live status and a raw data preview.
