What Is Oku in Gem Wallet?

What Is Oku?​

Oku is a trading interface and aggregator for Uniswap v3-style pools, built by GFX Labs. Gem Wallet uses Oku's deployments for same-chain swaps on networks where Uniswap itself is not deployed.

You don't select Oku yourself. When you swap, Gem Wallet compares quotes from all supported swap providers and shows Oku when it offers a route for your pair. The provider is shown on the swap screen before you confirm.

Supported Networks​

Gem Wallet uses Oku for same-chain swaps on: Sonic, Mantle, Gnosis, Plasma, and Sei EVM.

Both assets must be on the same network. To move assets between networks, Gem Wallet uses a cross-chain provider.

note

A pair only appears when the provider returns a live quote for it. Liquidity, amount limits, and route availability can change at any time.

If a Oku Swap Fails​

A Oku swap is a single transaction on the selected network, so it either completes or fails as a whole. If it fails, the assets you were swapping stay in your wallet, but the network fee is still spent.

Common causes are a price move larger than your slippage setting, low liquidity for the pair, or not enough of the network's coin for the fee. See Why Was My Crypto Transaction Reverted? and What to Do When No Swap Quote Is Available.

Need Help With a Swap?​

Contact Gem Wallet support from Settings > Support in the app, and include the transaction ID of your swap. Before you share anything, read What Information Is Safe to Give Wallet Support?.

warning

Gem Wallet support will never send you a direct message first, ask for your Secret Phrase or private key, or ask you to send funds to "fix" a swap. Anyone who does is a scammer.
