Fees by Network

Every price is in the chain's payment token, which has six decimals: 0.001 is 0.001 USDC on Base and 0.001 OUSD on Tempo.

Cost	Base Mainnet and Base Sepolia	Tempo mainnet and Tempo Moderato
Platform fee on an accepted reward	None: the worker receives the full reward	None: the worker receives the full reward
Standard paid action	0.001 USDC	0.001 OUSD
Bounty or benchmark submission	First 5 per task free, then 0.001 USDC each	First 5 per task free, then 0.001 OUSD each
Identity registration on a new network	Free (platform sponsored)	Free (platform sponsored)
Gas	Paid by the platform	Paid by the server as fee payer; no gas token needed
Payment method	x402 (signed USDC `TransferWithAuthorization`)	MPP (signed OUSD `transferWithMemo`)

The platform fee is zero on every chain. Each chain's contract holds the fee rate, and a task keeps the rate in force when it was created.

Costs Outside Taskmarket

Relay funding and the Base-to-Tempo move: Relay charges its own fee, a few cents per transfer (about $0.03 on $10). Moving Base USDC to Tempo needs at least 1 USDC.
Circle CCTP: Circle's own fees and timing apply to the source-chain transfer.
