AI agents need wallets not blank checks.
$sig17z brings USDG payments to Robinhood Chain with human-set spending caps, balance ceilings, pause/revoke controls, requests, history, webhooks and a machine-readable API.
Sign once. Spend within the seal. ✦

A Signet seal links its visual card to a public commitment and the underlying Robinhood Chain transaction. Inspect the seal, follow the on-chain explorer record, copy its public link, or share the generated card without exposing wallet credentials or signing another transaction. $sig17z

[SIGNET @sig17z]

Every settled Signet transfer can become a public payment seal: browse the live gallery, switch between the latest and rarest seals, then open a detail page to inspect the payment’s proof surface and its position in the transaction. $sig17z

[SIGNET @sig17z]

MCP tools and commerce agents need trustworthy state changes after a request moves. Signet supports scoped HMAC-signed webhook events, timestamp-and-body verification, and bounded retry backoff rather than infinite delivery loops. $sig17z

[SIGNET @sig17z]

Payment rails fail at the smallest unit. Signet requires decimal-string USDG amounts with up to six decimals never floating-point values before policy evaluation. A precise payload boundary for x402-style adapters without pretending the transport is native x402. $sig17z

Autopilot v1 just shipped 👇

→ agents swap USDG ↔️ AAPL/TSLA/NVDA via @Uniswap v3 on @RobinhoodApp chain
→ same per-tx + daily caps as payments — enforced on-chain
→ every swap mints a rarity card: https://t.co/ZA7ZOcZulz, speed.instant, slippage.tight
→ owner sweep pulls every stock home on revoke

open source: https://t.co/zBrNuidfHL

[SIGNET @sig17z]

Agentic commerce is more than push payments. An agent can create a payment request, inspect incoming requests, then explicitly accept or dismiss each one under the same human-set spending policy. No silent wallet pull and no automatic signing. $sig17z

[SIGNET @sig17z]

Give an agent a scoped payment identity without handing over the human wallet. Signet uses a one-time pairing handoff, exposes a machine readable API surface for MCP integrations, and lets credentials rotate immediately when access must change. $sig17z

[SIGNET @sig17z]

One payment. One public proof. One shareable identity layer.

Signet renders an OG card for each seal, gives it a stable share link, and keeps the underlying Robinhood Chain transaction independently checkable. Turn payment history into portable, verifiable distribution. $sig17z

[SIGNET @sig17z]

A payment card should be verifiable, not merely decorative.

Open a Signet seal to inspect its amount, parties, traits, score version, and transaction hash, then follow that same hash to Robinhood Chain Blockscout. The chain remains the source of truth. $sig17z

[SIGNET @sig17z]

Every confirmed Signet payment and every $sig17z transfer can become a deterministic seal derived from public Robinhood Chain data.

Browse the latest activity, rank seals by rarity, and open the live showcase. The traits come from the transactio, not a randomized metadata reveal. $sig17z

[SIGNET @sig17z]

Agentic payments need policy before execution.

Signet's live rails expose per-payment caps, rolling 24-hour limits, pause and revoke controls, and wallet balance as the hard ceiling. This is the control surface an x402 adapter can integrate with; native x402 transport is not live yet. $sig17z

[SIGNET @sig17z]

Signet gives agents a machine-readable payment surface on Robinhood Chain: one-time pairing, wallet and allowance reads, USDG sends and requests, key rotation, and signed webhooks.

That published API can be wrapped by MCP clients without placing a human wallet key on an agent server. Human-set limits stay in control. $sig17z

[SIGNET @sig17z]

Not every invoice should be paid. SIG17Z lets an agent inspect an incoming request and dismiss it without requesting a wallet signature or moving funds.

[SIGNET @sig17z]

The human keeps the switch. Once an agent is paused, a new send attempt stops at policy with HTTP 403 PAUSED before any server signature or transaction hash exists.

[SIGNET @sig17z]

Human-set limits are enforced before server signing. A 6.00 USDG draft against a 5.00 USDG cap is rejected with PER_TX_LIMIT no signature and no on-chain transaction.

Demo for new feature of Payment Seals on Signet ✦ Every Signet payment and $sig17z transfer can become a shareable seal, generated from public chain data, independently verifiable, and ready to unfurl on X.

[SIGNET @sig17z]

Payment Seals are live on Signet ✦
Every payment and $sig17z transfer on Robinhood Chain becomes a verifiable seal with its own rarity, OG card and public /seal/<txHash> page.
One tap turns settlement into distribution.
Posting demo video again in few minutes.

[SIGNET @sig17z]

An agent can create a USDG payment request without pulling from the recipient wallet. The request stays PENDING until the recipient makes a separate decision.

[SIGNET @sig17z]

Agents should know their boundaries before they spend. SIG17Z exposes the live wallet balance, per-payment cap, rolling 24-hour usage, and remaining allowance in one policy snapshot.

[SIGNET @sig17z]

Launching new feature today. Stay tuned for announcement. "Payment seals , shareable cards
Auto-generated OG image per payment at /seal/<txHash>, unfurling on X with the aurora look, plus a one-tap Share button prefilled with $sig17z. Turns every transaction into distribution."
