gblin

gblin is a skill for Claude Code, Codex from gblinproject/gblin-treasury-risk-regime. It costs 150 tokens per session (1,925 once invoked), scanned A, original, MIT.

A Base blockchain vault that holds cbBTC, WETH, and USDC as one ERC-20 token called GBLIN. It mints and redeems shares based on the basket's net asset value and can rebalance its holdings after a sharp fall in one asset.

In plain words
What is it for?
Use it to inspect the vault, plan or confirm token transactions, and mint or redeem GBLIN on Base, an Ethereum-compatible blockchain network.
Why use it?
It provides one token representing a basket of crypto assets instead of requiring separate management of each holding. The read-only endpoints allow checking its state without an API key or account.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

gblin scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GBLIN

One ERC-20 on Base backed by a basket of cbBTC, WETH and USDC held in the vault contract. Shares are minted and redeemed at net asset value (NAV) read from Chainlink feeds. When a basket asset falls sharply from its peak, the contract cuts that asset's target weight; a Dutch auction then rebalances the reserves. Redemption in kind needs no price and charges no fee.

Rules for the agent

  1. Read before you act. Call treasury-state (and plan when the user has a wallet) first. Quote numbers only from the responses, never from this file: weights, fees and the shield state change on-chain.
  2. Confirm with the user before every submission. Show the amount in, the expected and minimum amount out, the fee, and that the value of GBLIN moves with BTC and ETH. Wait for an explicit yes. Do not describe GBLIN as advice, a savings account or a yield product.
  3. Submit prepared steps in order and promptly. Every prepared transaction carries minimum outputs set from current prices. Send the steps one after the other within about a minute; if a step fails or time passes, prepare again instead of resending old calldata.
  4. Keep the gas limit a step carries. Steps that include a gas field must be sent with that limit (the vault reserves gas for capped transfers, so an automatic estimate can run out of gas).
  5. Never resend blindly. A failed submission that returned a transaction hash was broadcast; look the hash up before trying again.
  6. Arbitrary contract calls must be enabled in the Bankr wallet's Security settings for the raw steps below. Named swaps are not affected.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
