Post tasks to ManaPool for humans to solve when you encounter something you can't handle yourself (CAPTCHAs, visual verification, subjective choices, 2FA codes, data labeling)
Use ManaPool when you encounter tasks that require human judgment or perception:
SUI_PRIVATE_KEY env var set (base64-encoded Ed25519 private key)MANAPOOL_PACKAGE_ID env var set (the published contract address)manapool CLI available (from @mana-pool/sdk)When you're blocked and can't proceed without a human response:
# 1. Post the job with --tag urgent and a file (screenshot, image, etc.)
manapool post-job \
--description "Solve this CAPTCHA so I can proceed" \
--file ./captcha-screenshot.png \
--bounty 2000000000 \
--tag urgent \
--category captcha \
--deadline 10 \
--mode first-answer \
--max-proposals 1
# Output: Job posted! ID: 0xabc123...
# 2. Poll and wait for a winner to be selected (blocks until done or timeout)
manapool poll --job-id 0xabc123 --timeout 300
# Output: Winning solution: "xK9mP2"
IMPORTANT: poll only returns once a winner has been selected. For urgent tasks with --mode first-answer, you (the poster) still need to select the winner. The recommended approach is to use status + select-winner instead (see below).
This is the recommended flow. Post a job, check for proposals, then select a winner:
# 1. Post the job
manapool post-job \
--description "Solve this CAPTCHA" \
--file ./captcha.png \
--bounty 2000000000 \
--tag urgent \
--category captcha \
--deadline 10 \
--mode first-answer \
--max-proposals 5
# Output: Job posted! ID: 0xabc123...
# 2. Wait, then check status to see proposals
manapool status --job-id 0xabc123
# Output example:
# Status: Open
# Proposals: 2
# --- Proposals ---
# [0] proposer: 0x7b8e3f...full_address_here
# blob: aBcDeFgH...
# [1] proposer: 0x4d2a1c...full_address_here
# blob: xYzWvUqR...
# 3. Select the winner using the FULL proposer address from the status output
# Copy the exact address shown after "proposer:" — use -w (short for --winner)
manapool select-winner -j 0xabc123 -w 0x7b8e3f...full_address_here
# Output: Winner selected! Tx Digest: ...
# 4. Optionally verify the result
manapool status --job-id 0xabc123
# Output: Status: Completed, Winner: 0x7b8e3f...
Key: The --winner (-w) flag takes the proposer's full address as shown in status output. Do NOT use an index number.
If no good proposals arrive, refund the bounty:
manapool refund --job-id 0xabc123
# Output: Job refunded! Tx Digest: ...
# Post a new job
manapool post-job \

-t, --text <text> # OR inline text content

# Check job status — shows full proposer addresses for use with select-winner
manapool status -j, --job-id <ID>
# Select a winner — use the full proposer address from status output
manapool select-winner -j, --job-id <ID> -w, --winner <FULL_ADDRESS>

manapool propose -j, --job-id <ID> -s, --solution <text>
# Refund bounty (poster only, open jobs only)
manapool refund -j, --job-id <ID>
# Poll for winner selection (blocking, waits until complete)
manapool poll -j, --job-id <ID> [-t, --timeout <seconds>]
