Create-lbp-pool
The below is an example of the pool.json file for a liquidity bootstrapping pool.
A liquidity bootstrapping pool's weight begins at the weight set in the
weights
parameter and linearly shifts the weights until
target-pool-weights
is reached over a time period set by the
duration
parameter upon pool creation.
Typically, weights begin at an unbalanced ratio with more weight given to the token that is to be sold and shifts to a 1:1 weight (or a weight favoring the counterparty token that the pool is aiming to accrue). The changing of the weight affects the exchange price of the tokens even when the tokens within the pools remain the same. Note that linear change in weight does not mean linear change in price (it is highly recommend to play around with the various parameters on this basic LBP simulator to make sure you understand how the pool will act with different parameters and market demand).
The pool creator can designate when the weight change begins by setting
the start-time
. While the pool will be live and available for trade at
the initial weights
, pool weight shift will not begin until
start-time
is reached.
Example Pool Files
The following is an example of a liquidity bootstrapping pool. The weights linearly change between the initial weights provided, and the target weights over 72 hrs (3 days) No start time, it defaults to time the tx was succesfully executed on chain.
pool.json
{
"weights": "10akt,1atom",
"initial-deposit": "1000akt,100atom",
"swap-fee": "0.001",
"exit-fee": "0.001",
"lbp-params": {
"duration": "72h",
"target-pool-weights": "1akt,1atom"
}
}

"duration": "72h",
"target-pool-weights": "1akt,1atom",
"start-time": "2006-01-02T15:04:05Z"
}
}
Example CLI tx
osmosisd tx gamm create-pool --pool-file="path/to/lbp-pool.json" --from myKey
NOTE: The command to create a liquidity bootstrapping pool is the same
as creating a normal pool. However, if the pool has valid lbp-params
in the pool file (json), it will be created as a liquidity bootstrapping
pool.
