Turn swaps into revenue
Set your own fee on every swap, paid out to you in USDC.
Competitive execution
Route through aggregated liquidity for competitive pricing, without building or maintaining routing logic yourself.
Same-network and cross-network
Trade within a network or move value across them, including between EVM chains and Solana, through a single integration.
Monetize what your users do onchain
You set the fee, and Turnkey powers execution and settlement.
Set your rate
Choose your fee on every swap and your share of the yield your users generate.
Your users transact
Fees accrue automatically as swaps execute and balances earn. Nothing to invoice or reconcile.
Get paid
Swap fees settle to you in USDC. Your yield share accrues in the asset your users deposited and are paid out to you in-kind.
