Swap USDT from Solana to USDC on Base
Swap USDT from Solana to USDC on Base. Tether's SPL mint leaves Solana, and Circle's native USDC is what can arrive on Base. The older bridged USDbC token is not this contract.
Send Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB from Phantom. Solscan is the explorer, and there is no ERC-20 approval. Circle on Base is 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, chain id 8453. Basescan is the check. Base is an Ethereum L2. Gas is ETH at 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE. Ethereum's Circle USDC is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on chain id 1, about 12 second blocks, Etherscan.
Native USDC and USDbC still split Base deposits
Tether becomes Circle, and neither pays the L2
Mainnet USDC is not a slow version of this credit
A Solana issuer swap is enough when Base was optional

Frequently asked questions
What is the best way to swap USDT from Solana to USDC on Base?
Send Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB from Phantom. Solscan is the explorer, and there is no ERC-20 approval.
Does Solana USDT arrive as bridged USDbC on Base?
No. Circle's native USDC at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 is what can arrive on Base, chain id 8453. USDbC is a different contract. Tether's mint left Solana. Check Basescan. If the app still names the bridged token, this route is wrong. ETH is required to move the USDC.
What pays gas on Base after the USDC lands?
ETH, the sentinel 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE, on chain id 8453. Base is an Ethereum L2, and USDC cannot pay it. Hold ETH in the EVM wallet. Phantom signed the SPL mint with SOL. There is no ERC-20 approval on Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB. Confirm the contract on the explorer before you sign.
Is this the Ethereum USDC contract?
No. That address is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 on chain id 1, about 12 second blocks, explorer Etherscan. This credit is Base only. If the receiver pasted the mainnet contract, choose another route. Confirm 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Basescan. Keep the destination gas token or the arrival cannot move. The quote minimum is the floor, and a thin floor is a reason to stop.
