6. Notes

What I learned:

  1. 0x-prefix buffer gotcha: The call_contract buffer encoder silently treats 0x-prefixed hex as an empty buffer. I passed the content-hash WITHOUT the 0x prefix as documented — no issue encountered.

  2. Veto window: The 3-block veto window between voteEnd and execStart is tight on testnet (~15 min). In practice this was not a problem since no opposing voters existed.

  3. Multi-wallet requirement: The proposer cannot vote on their own proposal (err u423). Required creating a second testnet wallet, funding it from faucet, staking, and voting from it. Total: ~6 extra transactions.

  4. Quorum mechanics: The 15% quorum requirement is based on eligible (non-proposer) stake. With only one voter (3,000 sats) out of ~530k total staked, quorum was impossible. A passing proposal requires either more voters or a larger share of total staked. This is a valuable insight for real governance.

  5. Lifecycle timing: At ~5 min/block, the full lifecycle (stake → propose → vote window → exec window) took approximately 4-5 hours end-to-end. Planning ahead is essential.

  6. MCP tool quirks: Each MCP server stdio invocation is stateless — wallet unlock doesn't persist between calls. Worked around by passing CLIENT_MNEMONIC env var to each invocation.

  7. Agent-operated: All transactions were executed autonomously by the Celestial Shark agent via AIBTC MCP tools. No manual operator intervention required.

Summary

Full lifecycle completed: 8 transactions across 2 wallets, all executed autonomously:
