Pools

Create Bonding Pool

This endpoint creates a single-sided liquidity pool where only one asset (asset A) needs to be deposited initially. The pool uses a Linear Price Ramp bonding curve mechanism to establish price discovery and liquidity bootstrapping.

Single-Sided Pool Mechanics

Single-sided pools use a Linear Price Ramp bonding curve that differs from constant product pools:

Only asset A requires an initial deposit
Price follows a linear progression: P(S) = P_start + S * (P_end - P_start)
Where S is the fraction of tokens sold (tokens_sold / initial_supply)
Ideal for new token launches and price discovery
Graduates to constant product (x*y=k) after reaching graduation threshold

Pool Creation Process

Validate request parameters and authentication
Verify host configuration and fee structure
Calculate Linear Price Ramp parameters (start/end prices)
Submit pool creation to the settlement service
Store pool metadata for deposit confirmation
Return pool ID and deposit instructions

Fee Structure

Fees are split between:

LP providers (lp_fee_rate_bps)
Host platform (if namespace provided)
Flashnet protocol

Authentication

Requires a valid JWT bearer token. The token’s public key must match the pool_owner_public_key in the request.

After Creation

After successful creation, the pool owner must:

Send the initial asset A deposit to the pool’s address
Call the confirm deposit endpoint to activate the pool

Arguments

pool_owner_public_key - Public key of the pool creator
asset_a_token_public_key - Public key of the deposited asset
asset_b_token_public_key - Public key of the paired asset
asset_a_initial_reserve - Amount to deposit
graduation_threshold_pct - Percentage of initial supply to sell before graduation
target_b_raised_at_graduation - Target asset B amount that determines end price
lp_fee_rate_bps - LP fee in basis points
total_host_fee_rate_bps - Total host fees in basis points
host_namespace - Optional host identifier
nonce - Unique value for replay protection
signature - Request signature

Returns

202 Accepted with pool creation details and deposit address
400 Bad Request if validation fails
401 Unauthorized if authentication fails
500 Internal Server Error if creation fails

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json

Single-sided pool creation parameters including bonding curve configuration and fee settings

Request body for creating a new single-sided AMM pool.

Single-sided pools allow liquidity providers to deposit only one asset (asset A), while the pool creates a Linear Price Ramp bonding curve against a paired asset (asset B). This is useful for launching new tokens with price discovery and initial liquidity.

poolOwnerPublicKey

string

required

Public key of the pool owner who will control the pool. Must match the authenticated user's public key.

Example:

"03b06b7c3e39bf922be19b7ad5f19554bb7991cae585ed2e3374d51213ff4eeb3c"

assetAAddress

string

required

Address of asset A (the deposited asset). This is the asset that liquidity providers will deposit.

Example:

"0338d6978bd3163d1547f9ddb8b215d1c163bc7b4a552e559b89057f5449ba69de"

assetBAddress

string

required

Address of asset B (the paired asset). This asset forms the other side of the trading pair.

Example:

"020202020202020202020202020202020202020202020202020202020202020202"

assetAInitialReserve
