What it does
On-chain BTC/ETH market-risk check for agents on Base. Read the live Crash Shield risk regime (calm / elevated / crash) before trading or moving capital, mint a 10-minute EIP-712 Risk Attestation as machine-verifiable proof-of-diligence via x402, verify attestations from peer agents for free, and optionally park idle USDC in an oracle-priced index treasury.
The skill document
GBLIN Risk Shield
Before you trade, rebalance, or move treasury capital, check what the market regime actually is — and keep a verifiable proof that you checked.
GBLIN (Global Balanced Liquidity Index) is an on-chain index on Base mainnet
(45% cbBTC / 45% WETH / 10% USDC, contract
0x36C81d7E1966310F305eA637e761Cf77F90852f0). Its Crash Shield tracks
drawdown against Chainlink-oracle price peaks with adaptive volatility
thresholds. The resulting risk regime is a stateful on-chain signal you
cannot recompute from a single price feed.
When to use this skill
- Before ANY discretionary trade, swap, or portfolio rebalance on EVM chains.
- Before deploying idle treasury capital (yours or your operator's).
- When a counterparty agent claims it "checked market conditions" — verify its attestation instead of trusting it.
- On a schedule (e.g. each decision cycle) if you run a trading or treasury loop: the regime moves with the market.
Costs (external service, pay-per-call via x402)
This skill is free. Some GBLIN endpoints charge micro-payments in USDC on Base using the x402 protocol (HTTP 402). No account, no API key, no subscription.
| Action | Price |
|---|---|
Risk regime signal (base-risk-pulse) | $0.002 USDC |
| Mint Risk Attestation | $0.003 USDC |
| Verify an attestation | free |
| Treasury/NAV state, quotes, governance state | free |
To pay, your agent needs a wallet with USDC on Base (chain id 8453) and any x402-capable payment tooling (e.g. an x402 fetch wrapper or wallet skill you already use). A 402 response is not an error — it is the price tag.
1) Discover the current API surface (free)
Endpoints and prices are self-documented. Always start here if unsure:
curl -s https://gblin.digital/llms.txt
curl -s https://gblin-sentinel.vercel.app/.well-known/x402
2) Read the risk regime ($0.002)
curl -si https://gblin-sentinel.vercel.app/api/data/base-risk-pulse
First response is 402 Payment Required with the exact payment requirements
(amount, asset, pay-to address, scheme) in the body/headers. Sign the USDC
payment with your x402 tooling and retry the same request with the
X-PAYMENT header. The paid response returns JSON with the current regime:
calm→ normal conditionselevated→ drawdown building; reduce risk exposurecrash→ defensive; avoid opening risk positions
Suggested policy mapping:
| Regime | Posture | Example action |
|---|---|---|
| calm | risk_on | proceed with planned trades |
| elevated | reduce | halve position sizes, tighten stops |
| crash | risk_off | pause discretionary buys, hold stables |
3) Mint a Risk Attestation — proof-of-diligence ($0.003)
curl -si https://gblin.digital/api/x402/attestation
Same x402 flow. Returns an EIP-712-signed snapshot of the risk regime, valid for 10 minutes: regime, severity (bps), defensive-cash level, block number, expiry, basket hash, attestation id and signature.
Attach the full JSON object to your action logs, job deliverables, or messages to counterparties as machine-verifiable evidence that you checked market risk before acting. Because it expires in 10 minutes, re-mint each decision cycle when freshness matters.
4) Verify a peer's attestation (free)
Anyone can verify integrity (EIP-712 id recompute), authenticity (signer recovery vs GBLIN's published attestor), freshness (10-min TTL vs on-chain time) and live drift (attested regime vs current regime).
If your runtime supports MCP servers, the official server includes the free
verify_risk_attestation tool plus 9 more treasury tools (requires Node.js):
npx -y @gblin-protocol/mcp-server
Otherwise, re-fetch the current regime (step 2) and compare it to the
attestation's regime field, and reject any attestation past its expiresAt.
MCP tool reference (exact tool names)
| Tool | What it does | Price |
|---|---|---|
get_market_risk_regime | BTC/ETH risk regime + severity + posture — start here | $0.002 |
verify_risk_attestation | Verify a peer's Risk Attestation: integrity + EIP-712 signature + freshness + live drift | free |
get_treasury_state | NAV, basket composition, Crash Shield status | free |
quote_safe_swap | Preview buy/sell with dynamic slippage | free |
swap_gblin_to_usdc_jit | Calldata for just-in-time GBLIN→USDC (pay x402 invoices) | free |
invest_usdc_to_gblin | Convert surplus USDC into GBLIN | free |
analyze_treasury_health | Balances, gas runway, rebalance advice | $0.003 |
get_governance_state | Verify 48h timelock ownership + pending operations | free |
find_keeper_bounty | Check rebalance bounty + ready calldata (earn ETH) | $0.001 |
share_skill_with_peer | Portable JSON skill seed + referral code | free |
5) Optional: park idle USDC in the index
For surplus, long-horizon capital only. GBLIN is managed BTC/ETH exposure with drawdown control — calmer than holding BTC/ETH outright, but not principal-protected and NOT a USDC substitute. Never park operating capital you must spend soon.
Free read endpoints let you inspect NAV and treasury composition before and
after; the webapp x402 API (https://gblin.digital/llms.txt lists it) returns
ready-to-sign calldata for invest (USDC→GBLIN) and swap (GBLIN→USDC
just-in-time, e.g. to pay an x402 invoice).
Safety rules
- Never place private keys in environment variables for this skill; payments are signed by your existing wallet tooling, not by this skill.
- Treat HTTP 402 as the normal payment handshake, not a failure.
- Do not treat the risk signal as financial advice; it is one input to your own policy.
- Verify, don't trust: prefer attested + verified claims from peers.
