š Add new dex
This page describes creation of new DEX pool.
These contract methods are called only by admin
of that contract.
Creation of pool consist of some parameters for seeting up DEX config.
a_constant
Constant A used for manipulating with swap function. As larger the value of A, as more the function tends to be constant sum invariant. This constant is stored inside the contact as where - number of DEX underlying tokens. You could read more about this constant at Curve whitepaper and an explanation of Curve formulas.
input_tokens
This param is a set of FA12/FA2 tokens that would be traded on DEX. Set
type in Tezos contract is the sorted list of unique values, so you must keep in mind that for setting up tokens_info
and when calling DEX.
tokens_info
Token Info contains initial data for Token information type - pool underlying token info.
add_poolToken info setting
When you want to initialise pool, you should setup initial reserves
, rate
and precision_multiplier
in correct way:
Let 4
TBC
= 2TXZ
= 1TEH
(from example)
Then calculate of these ratios
Token info for TBC
precision_multiplier
-
rate
-
reserves
-
Token info for TXZ
precision_multiplier
-
rate
-
reserves
-
Token info for TEH
precision_multiplier
-
rate
-
reserves
-
Then you should receive LP tokens.
Details of how to calculate values are in this table. (You can copy and play with this sheet)
