GBLIN Protocol

Finance

Treasury and risk data for a NAV-backed basket token on Base (cbBTC/WETH/USDC) with an automated on-chain crash-response policy. Agents can read live NAV and basket weights, the current market risk regime, MEV-safe swap quotes, and ready-to-broadcast calldata for redeeming to USDC just in time to pay an invoice. Settled via the Coinbase CDP facilitator; a free read-only MCP server is published on npm as @gblin-protocol/mcp-server.

Pay from $0.001 to $0.003 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

risk clean

No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.

Top buyer share is a concentration signal, not part of the ranking score.

WHAT IT DOES

ai-derived

GBLIN Protocol provides an API for AI agents to interact with a treasury standard on Base mainnet, offering services like reading protocol state, getting swap quotes, and generating calldata for investment and redemption operations.

OVER TIME

All charts share the 30d window selected here. Every series is also served as JSON at /api/v1/services/gblin-protocol/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
