Swap USDC from Solana to USDT on Arbitrum One

Swap USDC from Solana to USDT on Arbitrum One. Circle's SPL mint leaves Solana, and Tether on Arbitrum One is what can arrive. ETH, not USDT, pays the L2 fee.

Send EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v from Phantom. Solscan shows the mint, and there is no ERC-20 approval. Tether is 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 on Arbitrum One, chain id 42161, not Nova. Arbiscan is the explorer. Gas is ETH at 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Circle's native USDC on this chain is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831, which this route does not deliver. Ethereum mainnet is chain id 1.

Diagram for Swap USDC from Solana to USDT on Arbitrum One
USDC leaves Solana. USDT is what can arrive on Arbitrum One.

Arbitrum One is not Nova and not mainnet

Chain id 42161 is the only network where 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 is this balance. Nova will not show it. Ethereum, chain id 1, about 12 second blocks, Etherscan, has its own Tether with a fussy allowance. Do not import that mainnet address on Arbitrum and call it the same coin. If the receiver wanted Circle, this Tether arrival is the wrong issuer.

USDT cannot pay the first Arbitrum transaction

ETH does. The sentinel marks that gas, not the stablecoin. A fresh address can receive Tether and still be unable to forward it. Hold ETH on 42161 before you try. Phantom paid with SOL and will not display the ERC-20. There is no Solana approval to revoke. MetaMask shows the credit only after the network badge says Arbitrum One.

Solscan and Arbiscan do not share a clock

The mint can leave Phantom while Arbiscan is still quiet. That gap is the bridge, and this page will not time it. Arbitrum One is the arrival. Sending the Circle mint again because the EVM wallet looks empty is how you spend twice. Confirm the chain id before you judge the balance.

A Solana dollar swap wins when Arbitrum was optional

Circle and Tether both exist as SPL mints. Use them when nobody named the Arbitrum contract. Cross when the invoice says 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9. The minimum USDT is the floor. A stablecoin hop can still slip. Refuse a number you would not deposit.

Does Solana USDC arrive as USDC on Arbitrum One?

No. Circle's mint EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v leaves Solana and Tether at 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9 is what can arrive on Arbitrum One, chain id 42161. Circle's own USDC there is a different contract. Check Arbiscan, not Nova. ETH pays gas. If the receiver said Circle, this route is wrong. Confirm the contract on the explorer before you sign.

Will the USDT cover Arbitrum fees?

No. Gas is ETH, sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on chain id 42161. Hold ETH before you move Tether. Phantom signed the SPL mint with SOL and will not show this token. There is no ERC-20 approval on the Solana side. Keep SOL so the source transaction can be signed.

Is this Ethereum's USDT contract?

No. Ethereum Tether is on chain id 1, about 12 second blocks, explorer Etherscan, and it has its own allowance behavior. This credit is Arbitrum One only. Nova is a different network.
