Circle Dog · Aros · Live on Robinhood

One token.
Two chains.
One eventual home.

Circle Dog is live in its official Robinhood Aros / USDG pair. Holder balances are mirrored to Arc after confirmations and batched settlement, until the final migration makes Arc the token's permanent home.

How it works

Trading there. Ownership visible here.

Robinhood is the source of truth during the bridge-waiting phase. Arc stores absolute holder balances, not a second market.

Launch

The official Aros / USDG Uniswap V2 pair launched with the full 1 billion Aros supply and 2,990 USDG of initial liquidity.

Trade & sequence

Users buy and sell through the official pair. Every user balance change receives a strict sequence; direct wallet transfers stay disabled.

Mirror

After 20 confirmations, the relayer groups changed addresses and writes their final balances to Arc in one batch.

Migrate

Source trading closes, the last sequence is reconciled, liquidity moves out, and Arc becomes the live ERC-20 home.

State machine

A controlled path with one irreversible turn.

MIRRORING→LIVE · 0% TAX

Pause is reversible. It stops public trades without ending the migration window.

Close is final. It freezes the source sequence; only after Arc catches up can liquidity be migrated and Arc transfers be enabled.

The temporary tax

Gas is the scarce bridge before the bridge.

Arc uses stable-value gas, but access is constrained before normal bridging opens. Project-reported OTC quotes for Arc gas have reached roughly 40× face value.

3%Tax during Robinhood trading

Collected in Aros on buys and sells; each trade must be worth at least 10 USDG.

~40×Reported OTC premium

The reason gas funding needs a temporary mechanism.

0%After Arc migration

No transfer tax in the final Arc ERC-20 state.

3% Aros→Fee wallet→Batch sale to USDG→OTC Arc gas

Controller inventory, the official Pair balance, and collected tax are system balances. Arc represents them together in the Dev Reserve rather than as separate holders; only user balances are mirrored. This is an operating-cost mechanism—not a promise of price support, yield, or return.

The Aros story

First, dog treats. Now, a path into Arc.

In 2015, Circle posted about a dog named Aros learning that Bitcoin could buy treats. The name now sits one letter away from Arc—and the payment idea still lands.

Then, Bitcoin made a new payment rail feel ordinary enough to buy dog food. Now, Robinhood USDG can buy Aros while its ownership is reflected on Arc before direct bridging is available. Different rails, same instinct: remove the payment boundary.

“Aros just learned he can buy dog treats with #bitcoin! Another happy Circle customer (arguably our cutest)!”
