Stable

EVM Layer 1 / Chain ID 988 / Private dataset

Stable is a payments Layer 1 that uses USDT0 as its native gas token, so stablecoin transfers settle at predictable sub-cent fees without holding a separate gas asset.

Stable on SQD

Validated at ingestion

Stable data is validated by SQD Network workers before it reaches the Portal. Validation is performed across the network rather than by a single ingestion node, so a faulty upstream source can't poison the dataset.

Decoded, schema-typed

Stable data served as decoded, schema-typed tables, ready to query. Your indexer queries the data directly without writing RLP parsers.

Archive plus real-time

Single Portal endpoint serves Stable through the current head, with sub-second hot-path latency. No separate streaming pipeline to wire up.

Open-source SDK

Both the Squid SDK and the Pipes SDK are open-source. Connectors for Postgres, ClickHouse, MongoDB, SQLite and Parquet, plus a custom-target hook. Run your Stable indexer on your own infrastructure or on SQD Cloud.

Frequently asked questions

How does SQD compare to running a Stable RPC node?

A Stable RPC node serves raw bytes for recent state and rate-limits per request. SQD's Portal pre-indexes the full Stable archive into decoded, schema-typed tables (blocks, transactions, logs) and serves them as a single streaming endpoint. You skip the multi-day node sync, archive storage, monitoring, and scale-out work, and pay only for the data you stream.

What does SQD cost for Stable data?

Stable is available to Enterprise customers via SQD Private Portal. Contact us for pricing.

How is SQD's Stable data different from a block explorer like Etherscan?

Block explorers are read-optimized for human browsing of single blocks or addresses. SQD is built for programmatic indexing: stream millions of Stable blocks into your own database, run analytical queries across the full history, and back production applications with decoded data. Output is structured tables, not HTML pages, and there are no per-call rate limits geared toward UI traffic. If you wanted to build your own Stable explorer, the SQD Portal is what you would back it with.

Can I self-host SQD's Stable indexer?

Yes. Both the Squid SDK and the Pipes SDK are open-source. You can run a Stable indexer on your own infrastructure pointing at the SQD Network or the Portal. SQD Cloud also offers managed hosting if you'd rather not operate it yourself.

Can I export Stable data to a data warehouse or pipeline?

Yes. The Pipes SDK streams Stable data from the Portal into Postgres, ClickHouse, MongoDB, SQLite, Parquet, or a custom target you implement. See the SDK docs for the connector reference.

Does SQD validate Stable data?

Every Stable block ingested into SQD is validated by the SQD Network workers (hash chain, parent reference, and where applicable finality) before it reaches the Portal. Validation is performed across the network, not by a single ingestion process, so a faulty upstream node can't poison the dataset.

Does SQD support real-time Stable data?

Yes. Stable is served with both real-time and historical data from the same Portal endpoint, with sub-second latency on the hot path. No separate streaming pipeline to wire up.
