Smart contracts

RaaS (Renew, Repair, Replicate as a Service)

RaaS was a smart-contract-based approach to automating storage deal renewal, repair, and replication on Filecoin. It supported both self-hosted and aggregator-hosted (via Lighthouse) architectures.

Key resources:

• RaaS Starter Kit

• Lighthouse documentation

Aggregated deal-making

A workflow for bundling many small data pieces into larger Filecoin deals using data aggregation and Proof of Data Segment Inclusion (PoDSI).

Key resources:

• FRC-0058 — Proof of Data Segment Inclusion

• Data segment specs discussion

• Filecoin Data Tools

Cross-Chain Data Bridge (CCDB)

CCDB enabled EVM-compatible chains (Avalanche, Base, etc.) to initiate Filecoin storage deals via cross-chain messaging through Axelar.

Key resources:

• onramp-contracts

• xChainClient

• dataBridgeDemo

• Architecture deep-dive (Medium)

Client contract tutorial

A tutorial on creating storage deals programmatically via FVM smart contracts using the deal-making starter kit.

Key resources:

• FVM deal-making kit

• ETHGlobal walkthrough (YouTube)

Chain data query

A tutorial on querying Filecoin chain data from a dApp using ethers.js against a public Glif JSON-RPC endpoint. For current chain access, use the Mainnet RPCs or Calibration RPCs and the FEVM indexers guidance.

Projects

Saturn

Saturn was a Web3 CDN in the Filecoin retrieval market, enabling fast content delivery from Filecoin storage providers. The project is no longer active.

For current retrieval guidance, see Basic retrieval and Serving retrievals.
