"How to bridge into Arc without the premium?"
The common way is via official CCTP for USDC bridge but that's not open to retail yet.
I've compiled some options you can take:
1) Expensive and usable
What it is:
> OTC desks selling native USDC at a markup
> You buy genuinely native Arc USDC from a maker who already holds it, and pay a premium for the fact that they can and you can't.
> Unstable OTC runs ETH USDC into Arc USDC at a 3% taker fee with a maker-set premium on top.
Caveats:
> Your real risk is maker delivery and the reclaim timeout. Use this bucket only when you need native USDC now and will accept paying for it.
2) Mid-premium and custodial
What it is:
> Claim bridges where trust sits with a team vault
> Cheaper than a filled OTC clip, because the USDC you end up with is backed by an operator's vault rather than by Circle
> The
@Longdotsupply stock leg ( $CRCL, $NVDA and similar) uses a 1:1 claim bridge from Robinhood Chain at 1% each way.
> The long ETH or WETH leg runs the same bridge with an all-in near 80%, useful mainly as a gas bootstrap since the first transfer over 20 dollars seeds 0.1 USDC of dust.
Caveats:
> The backing is on-chain but redeemable only if the operator honours it
> The instability is operational rather than price-driven: RPC congestion, domain swaps, public vault-withdrawal claims
> The premium should compress upon mainnet
3) Advertised cheaper
What it is:
> A route that advertises a 1:1 rate but settles through a shallow pool, so the pool's balance that hour decides what you actually get out
>
@ellipsefun ( $GLD, $USDT, $CRCL, $BTC) has you lock on Robinhood, claim on Arc, then sell the pair
> There is a daily cap and a queue
> Premium depends on pool liquidity - one public test put 150 dollars in and pulled 80 out, an effective 1.88x, with the rate depending on which asset was short at the time
Caveats:
> When the pool is one-sided the premium is very high, and it only beats the OTC desks when coverage happens to be balanced
Across all three, the number moving is the premium, and the premium exists for one reason - which is the get to the trenches earlier.
If you can wait, the cheapest bridge into Arc is the calendar.
If you cannot, price the workaround honestly - you are paying for time, and you should know which one you actually need and see if its worth it.
