Distribute TAO to hundreds of recipients in a single atomic transaction. Built for subnet operators, DAOs, and the Bittensor ecosystem.
Everything subnet operators need for efficient TAO distribution.
All recipients get paid or nobody does. Uses Substrate's utility.batch_all for guaranteed all-or-nothing execution.
Upload your miner/validator payout list as CSV or JSON. Auto-validates ss58 addresses and amounts.
Preview exact costs before confirming. See network fees and service fees broken down transparently.
Send to 1,000+ recipients. Spraay TAO automatically splits into optimal batch sizes and executes sequentially.
Import directly into your Python scripts. Perfect for automated reward distribution pipelines and bots.
Uses transfer_keep_alive to prevent draining wallets below existential deposit. Dry-run mode for testing.
Install from GitHub, create your recipient list, and execute. Spraay TAO handles the batching, signing, and submission to Subtensor.
Works on mainnet (finney), testnet, and local chains. Add --dry-run to simulate without executing.
Substrate-native batching. No smart contracts needed.
Provide a CSV or JSON file with ss58 addresses and TAO amounts. Spraay validates every address and checks for duplicates.
Spraay composes a utility.batch_all extrinsic containing all transfers, signs it with your coldkey, and submits to Subtensor.
All transfers execute atomically in a single block. If any fails, everything reverts. No partial payments, ever.
Any scenario involving multiple TAO recipients.
Distribute mining and validation rewards to all participants in one transaction.
Execute grant payments, treasury payouts, and governance distributions efficiently.
Pay all prize winners at once. Variable amounts, one transaction.
Reward contributors, beta testers, and community members with TAO.
Proven on Bittensor's live testnet.
