See the network, the supported assets, the provider state and the evidence behind an action — before a wallet is asked for anything.
Ryntra for Arc
A professional control layer for programmable money on Arc.
Ryntra brings network intelligence, owner-defined policy, human authorization and verifiable receipts into one Arc workspace.

Arc moves value.
Ryntra adds the control and proof around it.
Apply owner-defined policy, limits and approvals first. The signature stays a separate, explicit human act in a wallet you hold.
Compare what was authorized with what actually settled, and finalize a receipt anyone can recompute.
Ryntra never holds a key and never signs for you.
One Arc workspace.
Built for people, businesses and developers.
Workspace
For people and treasury teams. Mission Control, network intelligence, the money operations at their exact maturity, policies and receipts.
Guard API
For Arc applications and businesses. The same evidence, decision, reconciliation and receipt model behind a documented boundary.
Agent tools
Bounded, read-only facts and receipts for agents. Nothing that signs, authorizes, sends, swaps or changes a policy is in the first tool set.
Open it yourself at ryntra.io/arc/workspace — no account and no wallet are required to read it.
Start with one real workflow:
a controlled USDC payout.
The treasury defines who is paid, how much and why. Ryntra checks the action against the applicable policy, then the wallet owner authorizes and signs.

Receipt
Preview · live not verified Treasury Payout is currently a preview workflow; one separate direct USDC transfer has completed the full testnet receipt lifecycle.
Working today.
Expanding by proof.
TESTNET VERIFIED — direct-EOA ERC-20 USDC transfer only. The recorded proof covers the one operation that completed the whole lifecycle on Arc Public Testnet and nothing wider.
Arc Workspace
Open on Arc Public Testnet, without an account.
USDC lifecycle
One exact transfer reconciled end to end, with a finalized receipt.
Treasury Payout & Swap
Policy, approval and estimate are real; neither has been executed end to end.
Bridge & Unified Balance
Opened only after their own end-to-end proof and a recovery case.

Why Arc
USDC-native economics
Value and fees use the same dollar-denominated unit, which makes a budget, a limit and a total debit all readable in the thing being controlled.
Deterministic settlement
Arc simplifies network finality, so Ryntra can spend its complexity on the decision instead of on waiting — and still verify the application outcome separately.
Circle developer stack
App Kit, CCTP, Gateway and Agent Stack create a clear path from payments to programmable workflows, and a clear place for owner policy around them.
Arc reduces transport complexity. Ryntra focuses on decision quality, human control and proof.

Ryntra does not claim to be the first transaction firewall, the first policy engine or the only receipt product. Existing transaction-security, wallet-policy, compliance, signer and settlement systems remain competitors, adjacent providers or substitutes. No partnership with Arc or Circle is claimed.
