Place order

post

https://api.testnet.rise.trade/v1/orders/place

Place order via RISExUniversalRouter. Client signs permit (server does not hold signer keys).

Permit: Client signs EIP-712 VerifyWitness over order data. Server builds byte-packed payload and submits via Router.

Signature: 64-byte EIP-2098 compact (r + yParityAndS) or 65-byte (r+s+v, auto-converted).

Body Params

market_id

int64

Market ID (uint16)

size_steps

int64

Order size in steps (uint32)

price_ticks

int64

Order price in ticks (uint24, max 16777215)

Order side: 0=Buy, 1=Sell

post_only

boolean

reduce_only

boolean

stp_mode

Self-trade prevention: 0=ExpireMaker, 1=ExpireTaker, 2=ExpireBoth

order_type

time_in_force

int64

Time-in-force: 0=GTC, 1=GTT, 2=FOK, 3=IOC

builder_id

int64

Optional builder ID (uint16, 0 = none)

client_order_id

string

Optional client order ID (uint64, 0 = none)

ttl_units

int64

Optional TTL units for GTT orders (uint16, 0 = none)

permit

object

Permit parameters for v3 authenticated operations.
Client signs EIP-712 VerifyWitness; server builds byte-packed permit suffix.
Uses bitmap nonces for replay protection.

builder_fee_bps

int64

Per-order builder fee in parts per million, denominator 1e6 (uint16, 0 = none). 100 = 1 bps = 0.01%. 10 = 0.1 bps. Must not exceed the user-signed max for this builder (see ApproveBuilderFee). Setting this non-zero changes the signed action hash: builder_fee_bps must be encoded as an extra uint16 word right after builder_id (which is always part of the hash) and before client_order_id/ttl_units. Leave at 0 to use the hash layout without that word.
