Create Your Own Pair

Instantiation by Contract Address #

You should use the Dezswap factory contract.

The JSON message format is as follows:

{
  "create_pair": {
    "assets": [
      {
        "info": {
          "token": {
            "contract_addr": "xpla1..."
          }
        },
        "amount": "0"
      },
      {
        "info": {
          "native_token": {
            "denom": "axpla"
          }
        },
        "amount": "0"
      }
    ]
  }
}

This is a JSON constructor of pair contract. Tokens of pair can be either CW20 tokens or XPLA Chain native tokens(including IBC tokens). Use JSON keys with their corresponding values as described below.

• assets[x].info.token.contract_addr: CW20 token address
• assets[x].info.native_token.denom: XPLA Chain native token(including IBC token) denominator

Then, you may execute the contract with the organized JSON above.

If you want to register a brand-new XPLA Chain native or IBC token that are not listed yet, please find Dezswap team on #Dezswap discord (for metadata)

Provide initial liquidity #

Dezswap pair contract derives the swap rate from the amount of the remained assets on the pool. However, if you have just created your own pair and haven’t provided its liquidity yet, the contract won’t be able to calculate the rate and all swap simulations and transactions will fail. So, for the pair to work successfully, you should provide the initial liquidity.

A user can provide initial liquidity during creating a pair or by executing a distinct provide_liquidity transaction. When providing liquidity during pair creation, a user should increase an allowance to the factory address by the amount of CW20 tokens that he or she wants to provide to the pair. Otherwise, in case of providing liquidity by a separate transaction, the allowance needs to be increased for the pair contract.

Increase allowance (CW20 token) #

If one of or both of assets of the pair are CW20, you should execute increase_allowance before providing liquidity. You may follow the instruction from here. Don’t have to do this action of native tokens like XPLA.

• Make sure that you should input the pair contract address on spender.
• Make sure the input number amount that the number is multiplied by the decimal.

e.g:

xplad tx wasm execute <token_address> '{"increase_allowance":{"spender":"<pair_address>","amount":"<amount_with_decimal>","expires":{"never":{}}}}' --fees 200000000000000000axpla --from <your_key_name_on_local>

Provide liquidity #

Now you can provide the initial liquidity. Replace to your parameter and execute it!
Make sure that:

• The native token part should be input on both of contract & bash args, and the amount should be same.
• In --amount args, no space between the amount and the denom like <same_amount_above>atestfet.

xplad tx wasm execute <pair_address> '{"provide_liquidity":{"assets":[{"info":{"token":{"contract_addr":"<token_address>"}},"amount":"<amount_with_decimal>"},{"info":{"native_token":{"denom":"axpla"}},"amount":"<amount_with_decimal>"}]}}' --fees 800000000000000000axpla --from <your_key_name_on_local> --amount <same_amount_above>axpla
