CAPABILITIES

Everything you need to build on Bittensor.

Contract Indexing

Query any indexed ink! contract: events, transactions, balances, and blocks — all decoded from pallet-contracts in real-time.

Multi-Event Webhooks

Subscribe to any contract event by type. Filter by address, receive signed HTTP callbacks within milliseconds — no polling required.

On-chain Explorer

Browse blocks, transactions, addresses, and token balances through a live Bittensor explorer backed by the indexer.

OTC Trading

Swap PSP22 tokens for TAO and other tokens peer-to-peer with escrow-backed over-the-counter orders — no centralised exchange.

ink! ABI Decoding

Raw contract event data decoded automatically using registered ink! ABIs and delivered as structured, human-readable JSON.

Signed Payloads

Every webhook delivery is signed with HMAC-SHA256. Verify authenticity with your secret key before processing.

HOW IT WORKS

From chain to your stack in three steps.

Register a contract or webhook

Add your ink! contract address to start indexing. Optionally create a webhook to receive HTTP callbacks on any of its events.

We index the chain

Our node subscribes to Bittensor blocks via Substrate RPC, decodes ContractEmitted extrinsics against registered ABIs, and stores every event, transaction, and balance update.

Query, stream, or trade

Explore indexed data via the REST API, receive signed webhook deliveries in milliseconds, or place OTC orders to swap PSP22 tokens and TAO peer-to-peer.
