Off-chain storage with on-chain integrity
On-chain verifiable storage
Every object gets a cryptographic proof anchored to Filecoin that contracts can verify.
NFT metadata & asset hosting
Serve NFT metadata, images, and media at scale from a reliable S3-compatible endpoint.
Decentralized by default
Data is distributed across independent Filecoin providers, with no single point of failure.
Predictable, low-cost pricing
Flat $4.99/TB/month with no per-request fees and no egress charges as your dApp scales.
S3-compatible API
Use any S3-compatible SDK, including ethers.js flows that write metadata after mint.
Immutable object locking
Lock NFT assets and metadata so they can never be altered or deleted.
What teams are building
NFT collections
Host artwork, metadata JSON, and provenance records. Objects are content-addressed and immutable.
dApp backends
Back your dApp with verifiable, decentralized storage. One endpoint change, zero re-architecture.
Token-gated content
Store gated media behind presigned URLs, unlocked only for wallets holding the token.
On-chain game assets
Store items, skins, and save states with verifiable provenance players can check for themselves.
Frequently asked questions
The S3-compatible API means anything built for AWS S3 works here too. Point your SDK or CLI at our endpoint and authenticate with your API keys.
Security comes first in the S3-compatible design: setup and migration stay simple, and buckets are private by default. Public access with full S3 parity is coming soon.
Read Fil One docs, access the app to get started with no code required, or talk to someone on our team to get started.
Encryption is industry-standard, with per-object data encryption keys that protect your data regardless of which provider it's stored with. SOC 2 Type II and ISO 27001 certifications are actively in progress. Reach out to security@fil.one if you'd like to be notified when those finalize, or have other questions about security.
Filecoin is a distributed storage network launched in 2020, designed to make data portable, verifiable, and resilient by default.
Instead of relying on a single proprietary vendor, Filecoin uses open protocols and an open market to store data with a global network of independent providers, helping reduce single points of failure and deliver true multi-cloud durability.
