STEP 01
Filecoin
Prove
Storage Provider submits a Proof of Data Possession on Filecoin Calibration — cryptographic evidence that the data chunk is intact and stored.
Calibration TestnetStorage providers get paid per verified chunk. Miss the SLA? Automatic slash. Zero human intervention.
The infrastructure exists. The proofs are verifiable. The payments just weren't automated — until now.
Massive scale, zero payment automation
Since Filecoin genesis. Storage providers subsidize the network
Doing the work, not getting paid for it
SlaStream wires together three independent blockchains into a single, unstoppable payment rail. Each chain does what it does best — no trust required at any handoff.
Live pipeline
Storage Provider submits a Proof of Data Possession on Filecoin Calibration — cryptographic evidence that the data chunk is intact and stored.
Calibration TestnetLit Actions on Chronicle Yellowstone verify the proof and relay a signed cross-chain attestation to Starknet — no intermediary, no trust.
Chronicle YellowstoneThe Cairo smart contract validates the attestation and auto-streams the escrowed STRK payment directly to the storage provider.
Sepolia TestnetConnect your wallet, lock escrow, and let SlaStream handle the rest. Every proof verified, every payment streamed.
