Swap SOL from Solana to USDC on Arbitrum One

Swap SOL from Solana to USDC on Arbitrum One. SOL leaves Solana, and Circle's native USDC is what can arrive. It is not bridged USDC.e, and it is not mainnet USDC.

The quote names So11111111111111111111111111111111111111112, the wrapped SOL mint. Phantom signs, Solscan shows it, native SOL pays the fee, and there is no ERC-20 approval. Circle on Arbitrum One is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831, chain id 42161, not Nova. Arbiscan is the check. ETH at 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE pays gas. Ethereum USDC is chain id 1, about 12 second blocks, Etherscan.

SOL leaves Solana. USDC is what can arrive on Arbitrum One.

The native Circle contract is the whole test

0xaf88d065e77c8cC2239327C5EDb3A432268e5831 has to be the address in the app. USDC.e will not match. Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 will not match if the invoice said USDT. Arbiscan is how you prove which dollar you hold. Selling SOL into the wrong stablecoin is expensive to unwind, so read the destination before you size the trade.

Native SOL stays behind as the fee

The wrapped mint is what the route names. The fee payer is native SOL. Empty it and Phantom cannot sign. MetaMask cannot show So11111111111111111111111111111111111111112. There is no ERC-20 approval. After arrival, USDC cannot pay chain id 42161. Bring ETH or the dollars sit still. Nova will not display them.

Mainnet is not a delayed view of this credit

0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on Etherscan is a different USDC. About 12 second blocks describe that chain, not this bridge. How to bridge assets between chains is the switch from Phantom to an EVM wallet on 42161. Wait for Arbiscan. A second SOL sale because the first wallet looks empty spends more SOL.

A local mint is enough when Arbitrum is not the venue

Circle on Solana is EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v. Selling SOL into that mint avoids ETH, Nova confusion, and USDC.e. Cross when someone named the Arbitrum contract. The minimum USDC is the floor. A thin conversion of a fee coin into a dollar is still a bad trade if the floor is poor.

Frequently asked questions

What is the best way to swap SOL from Solana to USDC on Arbitrum One?

The quote names So11111111111111111111111111111111111111112, the wrapped SOL mint. Phantom signs, Solscan shows it, native SOL pays the fee, and there is no ERC-20 approval.

Is USDC from SOL the bridged USDC.e token?

No. Circle's native USDC at 0xaf88d065e77c8cC2239327C5EDb3A432268e5831 arrives on Arbitrum One, chain id 42161. USDC.e is different. SOL left as the wrapped mint. Check Arbiscan, not Nova. If the app wants the bridged token, this route is wrong. ETH is required to move the USDC. Confirm the contract on the explorer before you sign.

Can I sell every SOL?

No. Native SOL pays Phantom even though the quote says So11111111111111111111111111111111111111112. There is no ERC-20 approval. Leave a remainder. On Arbitrum, hold ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, or the new USDC cannot transfer on chain id 42161. Keep the destination gas token or the arrival cannot move.

Does this credit Ethereum USDC?

No. That contract is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on chain id 1, about 12 second blocks, Etherscan. This route credits Arbitrum One only. If the receiver pasted the mainnet address, pick another route. Confirm the Arbitrum contract before you sell SOL. The quote minimum is the floor, and a thin floor is a reason to stop.
