Developer Goals
- Prototype new dapps with realistic datasets (blocks, transactions, pools) without standing up heavyweight indexers.
- Enrich wallets or explorers with verified metadata (token registries, pool classifications, lineage proofs).
- Validate onchain workflows—deployment, settlement, compliance—against auditable tables.
Key Assets
| Need | Dataset / Endpoint | Why it matters |
|---|---|---|
| Execution primitives | blocks, transactions, logs | Fuel backends, analytics, and debugging with deterministic block data. |
| Contract + token metadata | contracts, erc20 tokens, erc721 tokens | Populate UI components, compliance checks, and upgrade monitoring. |
| Liquidity + pricing | liquidity pools, reserves, pricing layers | Build routing, quoting, and analytics services with normalized data. |
| Proof & lineage | Lineage endpoints, Verification suite | Provide “view onchain proof” buttons that recompute roots/log blooms. |
Delivery Workflow
- Backfill: hydrate dev/test environments using Archive SFTP or S3 buckets for deterministic datasets.
- Real-time sync: subscribe to WebSocket feeds or REST pollers for live UX updates (new pools, token listings, governance proposals).
- Environment targeting: use the Chain enumeration to toggle between mainnet and supported L2s/L3s; align dataset IDs with API payloads.
- Testing: leverage
_tracing_idto create reproducible fixtures; pair with Function Results for deterministic smart-contract outputs.
Best Practices
- Schema-first development: treat the SQL in
/BlockDb.Postgres.Tables.Publicas the contract for your backend models. - Access control: rely on delivery SLAs +
_updated_atfields to detect lag before it impacts production UX. - Version pinning: store the dataset ID + version (e.g.,
0101_blocks_v1) in your configuration to simplify upgrades when new versions ship.
When rolling out user-facing analytics (wallet insights, explorer charts), combine BlockDB datasets with your proprietary data via Visualization delivery guides or custom frontends that query curated APIs.
