Error in Solana Phantom: Decimal precision error for the tokens swap
As a developer of a decentralized application (DAPP) that changes tokens from a group of liquidity, you are probably not alien to working with tokens about Blockchain Solana. A common problem that can occur when using the Phantom Solana wallet is a decimal precision error when performing the tokens swaps. In this article, we will explore why this could happen and give a solution.
problem: Decimal precision error
When you change chips from one liquidity to another, the Phantom wallet will display the amount of exchange in decimal format (for example, 1000 soil). However, if you enter an amount, such as 1000, the ghost will automatically convert it to a fraction of the total amount available. For example:
- If you have $ 10,000,000 in liquidity basins and you want to change 1000 chips from one pool to another.
- Phantom transforms 1000 chips (in decimal format) into 1/10,000,000 from the total amount.
problem
The problem arises when the conversion is not exact. In a scenario in the real world, the liquidity basin could contain fractions or decimal that are not accurately represented in the solar chip system. This can lead to an error when trying to change chips because Phantom will display incorrect amounts.
Causes of decimal precision error
A few factors contribute to this decimal precision error:
- Rules of token conversion : The solar protocol defines specific rules for transforming between different types of chips and names.
- Fractional representation : Some types of tokens or liquidity basins may contain fractions that are not accurately represented in the chip system.
- The ghost wallet configuration : The ghost wallet configuration can affect the management of decimal precision errors.
Solution: Configure Phantom to manage decimal precision errors
To solve this problem, you can set up the Phantom Solana wallet to manage decimal precision errors:
- Go to
Settings> Wallables> Sola Pluing
- Select the liquidity pool where you want to change chips.
- Under
tokens settings , activate
fractional representation .
Example of configuration
For example, if you have a liquidity basin with activated fractional representation:
`Json
{
"Name": "Liquidyidpool",
"Symbol": "X",
"Type": "Liquidyidpool",
"Minamount": 1000,
"Maxamount": 1000000000,
"Fraction representation": true,
}
`
With this configuration, Phantom will display token amounts in a fractional form (for example, 1000/10,000,000).
best practices
To continue minimizing the risk of decimal precision errors:
- Make sure your liquidity group has an enabled fractional representation.
- Regularly update your wallet configuration to reflect any changes in the solar protocol or token system.
Following these steps and best practices, you can minimize the risk of decimal precision errors when changing chips on the soil using Phantom.
