Why swap USDC to USDT on Base with Orkid?
Stablecoin swaps between USD Coin and Tether USD are the most common DeFi transaction. Whether you are rebalancing between USDC and USDT for yield farming, or moving from DAI to USDC for payments, the goal is the same: get from one stablecoin to another with zero slippage and minimal fees.
How USDC-to-USDT swaps work on Base
Stablecoin-to-stablecoin swaps should execute at or near 1:1. Any deviation is slippage or fee extraction. Orkid's routing engine finds the deepest stablecoin pools on Base to minimize slippage, and the 9 bps flat fee means you know exactly what you are paying — no hidden spread.
Step 1: Connect your wallet
Connect any EVM-compatible wallet to Orkid. No registration, no KYC, no deposit. Your funds stay in your wallet until the swap executes.
Step 2: Select USDC and USDT
Choose USD Coin (USDC) as the input token and Tether USD (USDT) as the output token. Orkid automatically detects the best routing path across all Base DEX venues.
Step 3: Sign the swap intent
Instead of broadcasting a transaction to the mempool, you sign a message (via Permit2) authorizing the swap. This signature is sent to a solver who executes the swap on your behalf. No gas required from your wallet.
Step 4: Receive USDT
The solver executes the swap and Tether USD (USDT) arrives in your wallet within seconds. You pay 9 bps flat — no hidden fees, no spread, no gas charge.
Tips for USDC-to-USDT swaps
For large stablecoin swaps ($50K+), split into multiple transactions to avoid moving the pool price. Orkid's routing engine does this automatically when it detects that splitting reduces total cost.

Frequently Asked Questions
How much does it cost to swap USDC to USDT on Base?
Orkid charges a flat 9 bps (0.09%) fee on the swap value. There are no hidden spreads, no gas charges (gasless via Permit2), and no additional fees. On a $1,000 swap, the fee is $0.90. On a $10,000 swap, the fee is $9.00.
Do I need ETH to swap USDC to USDT?
No. Orkid uses Permit2 for gasless swaps. You sign a message approving the swap, and a solver executes the transaction on your behalf, paying the gas. The gas cost is included in the 9 bps fee. You only need USDC in your wallet.
How long does a USDC to USDT swap take on Base?
Swaps on Base typically execute within 2-5 seconds. Base has ~1-2 second block times, so your swap is usually included in the next block after the solver submits it. You will see the USDT in your wallet within seconds of signing.
Is swapping USDC to USDT on Base safe from MEV?
Yes. Orkid uses intent-based execution, which means your swap is not broadcast to the public mempool. A solver matches your intent and executes the swap privately. Sandwich bots cannot see your transaction, so they cannot front-run it. This is fundamentally different from swapping on Uniswap or 1inch, where your transaction is visible to MEV bots before it executes.
What is the minimum amount to swap USDC to USDT?
The minimum swap amount depends on the pool liquidity. For USDC-to-USDT on Base, the practical minimum is around $1 equivalent. Below that, the 9 bps fee (less than $0.01) may be smaller than the gas cost the solver pays, making the swap uneconomical. There is no maximum — Orkid handles large swaps via split routing.
