Casper Agentic Buildathon 2026
From prototype to production.
Sluice is built to be a real product, not a hackathon throwaway. Here's what's already
live on Casper testnet, and where the streaming x402 meter goes next.
Qualification Round · shipped
What's live today Shipped
- Per-second streaming x402 meter, running live on Casper testnet
- Interactive live demo console: one click runs a real agent session, settling on-chain in front of you
@sluice/x402 client SDK + sluice-mcp MCP server: any agent, including an LLM over MCP, can rent and pay for a stream- 301 real on-chain settlements · 5 autonomous agents · 3 providers · 17 recorded agentic decisions
- Three deployed Casper contracts: on testnet a CEP-18 X402 token and the
SluiceRegistry anchoring stream terms + settlement checkpoints, plus our own CEP-18 token on mainnet
- Trustless on-chain verifier: every published number is re-derived straight from the Casper ledger, so the feed can never over-claim
- Real CoinGecko price feed driving the trading-agent streams
Now → Final Round
Hardening & the SDK In progress
- Provider-side SDK: any provider drops a streaming paywall in front of an endpoint in ~5 lines
- Harden the meter: micro-batched settlement, reconnection, quota-aware pacing
- Expand the proof feed with more agents and more live streams
Final Round · shipped
Mainnet Shipped
- Sluice streams on Casper mainnet. The same meter, the same agent and the same x402 scheme settle real per-second payments on
casper:casper: 8 settlements across 2 streams and 2 providers, blocks 8381075 to 8381217.
- Our own CEP-18 token deployed on mainnet, and
npm run verify:mainnet checks every claimed mainnet settlement against a public mainnet node, with no API key and no account.
- Sluice runs its own x402 facilitator, so there is no third-party dependency in the settlement path on either network.
Q3 2026
Design partners Next
- 2–3 design-partner data / compute providers, starting with the trading-agent price-feed use case already proven on both networks.
- Usage-based revenue share for providers metering their resources through Sluice.
Q4 2026
Open network + agent SDK Planned
- Open provider onboarding: self-serve streaming paywalls
- Agent SDK so any autonomous agent can rent metered resources
- Pursue Casper grant / incubation
