Ryntra on Arc · Reviewer evidence
TESTNET VERIFIED — direct-EOA ERC-20 USDC transfer only. Every settlement figure on this page — amount, fee, block, hashes, statuses — is read from that run rather than typed into the markup. The product itself is at ryntra.io/arc.
One direct-EOA ERC-20 USDC transfer on Arc Public Testnet, authorized and signed by the wallet owner, reconciled against the chain and sealed into a receipt whose hash and integrity digest were recomputed independently of the application.
What you see while your wallet is still closed.
Before, settlement and after — each carrying its own truth label, because a frame without one invites the reader to assume it is a live capture.
The recorded proof covers the one operation that completed the whole lifecycle on Arc Public Testnet and nothing wider. Anything not covered by it carries its own weaker label. The last four rows have no registry record on purpose: nothing was proven, so there is nothing to register.
| Capability | Status | What that covers |
|---|---|---|
| Arc Testnet connection | TESTNET VERIFIED | Correct network and chain id confirmed against the chain. |
| USDC treasury transfer | TESTNET VERIFIED | One real direct-EOA ERC-20 transfer settled end to end. |
| Preflight and policy | TESTNET VERIFIED | Exact action and versioned policy evaluated before authorization. |
| Human authorization | TESTNET VERIFIED | Recorded separately from the policy result and from the signature. |
| Wallet signature | TESTNET VERIFIED | Performed by the key holder. Ryntra observes the resulting hash, not the act. |
| Transaction tracking | TESTNET VERIFIED | Confirmed and linked to a public Arc Explorer record. |
| Expected versus actual | TESTNET VERIFIED | Reconciled from chain data; the fee difference is recorded. |
| Execution receipt | TESTNET VERIFIED | Finalized only after confirmation, hash and integrity recomputed independently. |
| USDC to EURC swap | IN BUILD | Implemented in source. No real swap has ever executed. |
| Bridge and unified balance | IN BUILD | Visible in the product and deliberately disabled. |
| Reliability under load | IN BUILD | One successful run is not a reliability claim. |
| Arc mainnet | NOT VERIFIED | Modelled in the network registry and not selectable. No mainnet claim. |
Arc has no separate native gas token, so the cost of an action and the action itself are the same currency. The workspace shows one financial picture instead of two.
Arc keeps a single USDC balance behind an 18-decimal native accounting view and a 6-decimal ERC-20 transfer interface. Ryntra distinguishes them everywhere and never adds them.
Arc emitted this single movement as two Transfer events — 1000000000000000000 from the native precompile at 18 decimals, and 1000000 from the ERC-20 interface at 6. Reconciliation reads only the ERC-20 log, so the recorded amount is 1.000000 USDC rather than a 10^12 error.
One confirmation is final on Arc, so there is no countdown to wait through — but a receipt still waits for reconciliation, because confirmed is not the same as matched.
No. Ryntra prepares, checks and reconciles. The signature and the broadcast happen in a wallet you control, and Ryntra never receives a seed phrase, a private key or withdrawal authority.
One direct ERC-20 USDC transfer on Arc Public Testnet, executed by the wallet owner, reconciled against its expected effects and sealed into a receipt. Every settlement figure on this page — amount, fee, block, hashes, statuses — is read from that run rather than typed into the markup.
No. The request and the deterministic preflight are implemented against the provider contract, and execution stays disabled. No swap has been verified end to end, and nothing on this site says otherwise.
Because no indexer runs yet. Block time, gas in USDC, throughput, contract coverage and address activity need one with a stated backfill window, so they are named as unmeasured rather than estimated.
No. The Hub is reachable without one. A wallet adds address-scoped reads and is required before any authorization step; a Ryntra account adds the cabinet and the journal.
No. Everything here is Arc Public Testnet, where no real value moves. Mainnet is a separate release programme and never arrives through a network dropdown.

Ryntra Guard for Arc · Decision & Settlement Evidence for Programmable Money. STALE_PUBLIC_SNAPSHOT at b8af07a — Bounded public extraction; it predates the corrective candidate and does not prove source or deployment parity. The in-product verifier re-hashes a receipt this deployment stores; a receipt it has never stored answers NOT_FOUND, which is not a judgement about that receipt.
