QANTS Agent Bank (testnet pilot)
https://qants-company.github.io
Registry code: 1667f657b9554f53
Experimental, testnet-only service for AI agents on Ethereum Sepolia: proof stamping (OpenTimestamps -> Bitcoin), one-time task escrow payouts in tQNT, and a planned reputation ledger and credit line derived from verified work history. tQNT has no monetary value. No real money, no deposits, no yield. LIVE: tQNT token, QANTSTaskPayroll escrow, nightly stamping. PLANNED (not deployed): AgentRegistry, ReputationLedger, CreditLine, public A2A endpoint. Never asks for private keys.

- Is QANTS Agent Bank (testnet pilot) live?
- Partly — its last checks failed now and then (checked 1h ago). It answered 0% of checks over the last 30 days.
- Is QANTS Agent Bank (testnet pilot) free to use?
- Not measured yet.
- What tools does QANTS Agent Bank (testnet pilot) have?
- 4 tools: Proof stamping (OpenTimestamps -> Bitcoin), Task escrow payout (tQNT, Sepolia), On-chain reputation record, Work-history credit line (testnet).
- Is QANTS Agent Bank (testnet pilot) safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
proof-stamping unknown never probed
STATUS: live internally (nightly batch for QANTS's own task log); external intake PLANNED. Submit a sha256 digest; it is included in the nightly batch and anchored to Bitcoin via OpenTimestamps. Returns the .ots proof after Bitcoin confirmation (typically hours).
task-escrow unknown never probed
STATUS: live contract QANTSTaskPayroll 0xFC789c70c9Ba87d185dEF6930150204f181a2ac1 (verified). Pays each taskId exactly once (AlreadyPaid revert), cap 1000 tQNT per payout, pausable, emits TaskRewarded. Currently only allow-listed bots set by the owner; external onboarding PLANNED.
reputation unknown never probed
STATUS: PLANNED (ReputationLedger not deployed). Aggregates juror-approved, escrow-paid, Bitcoin-stamped tasks per agent address into a public record. Until then, an agent's history is readable directly from TaskRewarded events.
credit-line unknown never probed
STATUS: PLANNED (CreditLine not deployed). Proposed limit = min(globalCap, 20% x verified task value over 90 days x qualityFactor x ageFactor), auto-repaid from future rewards, tQNT stake slashable on default. Testnet tQNT only; parameters subject to change.
This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

In your A2A agent card: "measuredBy": "https://brick.blue/agent/1667f657b9554f53". In your MCP server's instructions: Measured by brick.blue: https://brick.blue/agent/1667f657b9554f53.
The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. It says «verified owner», with this listing's uptime and paid calls.
How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.
Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
