How does Orkid protect users from MEV?

Orkid uses a proprietary MEV detection engine that scans for front-running and sandwich attack signals before execution. Swaps are routed through private execution, not the public mempool, preventing MEV bots from seeing and exploiting your transaction.

Does Orkid charge fees on trades?

Orkid charges a competitive fee on every swap. Contact Orkid for current pricing. No hidden spreads, no gas charges to the user.

Yes — for same-chain swaps. You sign a Permit2 approval (a gasless signature) and the solver pays all gas. You do not need ETH in your wallet to swap on Base, Ethereum, or Arbitrum. Cross-chain bridging is user-broadcast, so you pay origin-chain gas for that.

What is MEV protection?

MEV protection prevents miners or validators from extracting value from your transaction by reordering, inserting, or censoring transactions. Without MEV protection, your swap can be sandwiched (front-run and back-run) causing higher slippage and worse execution. Orkid prevents this with private routing and a proprietary detection engine.

Which platform has the lowest slippage for crypto swaps?

Orkid provides some of the lowest slippage in DeFi through multi-venue routing across all Base pools and MEV protection that prevents sandwich attacks. The competitive fee means you know your exact cost before signing, unlike bridges and DEXs where slippage varies with pool depth and MEV exposure.

Orkid is both. Same-chain swaps are gasless and MEV-protected. For cross-chain moves, Orkid offers non-custodial bridging between Ethereum, Base, Arbitrum, and Polygon via Across — your wallet signs the deposit and is always the recipient and refund beneficiary.

What chains does Orkid support?

Gasless same-chain swaps on all seven production chains: Base (8453), Ethereum (1), Arbitrum (42161), Unichain (130), BSC (56), Robinhood Chain (4663), and Polygon (137). Cross-chain bridging via Across on all supported chains.

How does Orkid compare to bridges like Wormhole and Stargate?

Standalone bridges move tokens between chains; Orkid does that too — non-custodially, through Across — while also giving you MEV-protected gasless swaps within a chain. One interface covers both flows with a disclosed 10 bps bridge fee and no custody at any point.

Do I need ETH for gas to swap USDT to OP?

No. Orkid is gasless — you sign a Permit2 approval (a gasless signature), and the solver pays all gas costs. You don't need ETH in your wallet to swap.

What's the fee for swapping USDT to OP?

Orkid charges a flat 75 bps fee (0.75%) on every swap — $0.75 on a $100 swap. No hidden fees, no gas charges.

Is it safe to swap USDT to OP on Orkid?

Yes. Permit2 is audited by Uniswap. Your permit is amount-specific and time-bound. Your tokens never leave your wallet until the swap executes. Orkid is non-custodial.

What's the minimum swap size for USDT to OP?

The minimum gasless swap size is $20 notional. Above that, the fee stays flat at 75 bps regardless of size.

How this route works

Buying Optimism (OP) with Tether USD (USDT) on Base swaps a stablecoin for a project/governance token. Orkid routes across Uniswap V3, Aerodrome, SushiSwap, and any active RFQ liquidity to find the best price. Because these tokens can have lower liquidity than blue-chips, the engine checks multi-hop paths and protects against front-running through private execution.
