Fees

Fees

DAY charges 0.10% when it swaps or bridges your money. That’s the only fee DAY charges today.

No profit fee. No deposit fee. No withdrawal fee. Nothing to hold capital. Principal is never touched.

This page is the only place rates are written down

Every rate below comes from GET /api/v1/day/fees, which is the source of truth (runtime/config/fee-config.mjs). No other page in these docs states a rate — they all link here. Never hard-code a rate in a client: read the schedule, because rates are owner-settable and can change without a redeploy.

What DAY charges

Fee	Value	Status
Swap	0.10% of the amount swapped	Charged
Bridge	0.10% of the amount bridged	Charged
Deposit / withdraw principal	0	Locked off — never charged
Holding capital	0	Never charged

What exists but charges nothing

Fee	Value	Status
Profit / performance	1% of profit, capped $10 per harvest	Off. Wired and owner-settable; charges $0 today
Routing (x402)	$0.001 per API call	Advertised, not enforced. enforcement: "advertise_only" — charges $0 today

These are listed so nothing surprises you later, not because you pay them. If either is ever switched on, this page and GET /api/v1/day/fees change together.

Managed strategies: the leader sets their own fee

A managed strategy is an opportunity with a leader — someone who moves your money between pools as rates change, inside limits frozen when the strategy was created.

The leader sets their own performance fee on profit. DAY does not set it and DAY does not take it. It varies by leader, it is disclosed up front on the strategy, and it is paid to them. It is not one of DAY’s fees, and it does not apply at all if you picked a plain opportunity yourself.

Fee	Who sets it	Who takes it
Leader performance fee	The leader	The leader — not DAY
Venue / pool fees	The underlying protocol (Aave, Morpho, a DEX)	That protocol. Pass-through, disclosed separately

Profit / performance fee (currently off)

DAY’s performance fee is 1% of profit — realized yield only — capped at $10 per harvest, and only on non-managed strategies. It is not charged today: it is an owner-settable parameter that may be enabled later. It is never taken on deposits, on principal, or on unrealized mark-to-market. We show it here so it is never a surprise if it turns on.

  -H 'content-type: application/json' \
  -d '{"compound":true}'

At harvest, realized yield compounds back into the owner’s vault. The profit fee is off, so nothing is skimmed today. If it is ever enabled, it applies at harvest, on profit only, before the residual compounds — see the table above.

When each one applies

Swap / bridge (0.10%) — charged only when DAY actually converts or moves your asset to put it to work. A deposit that needs no conversion pays nothing. The DEX pool fee, price impact, and bridge-rail cost are separate third-party costs.

Bridge rail fee	Mayan / rail
Venue fees	Suilend, NAVI, Jito, Kamino, Morpho, Aave, …
