Protocol fee

There are limitations on the minimum possible amount to accept an offer. In this section, we will explore the reasons behind these limitations.

Shared Decimals

All token amounts are stored with the precision of Shared Decimals in the OTC market. In the current version of Bakstag Protocol, Shared Decimals value is set to 6. This means that the smallest amount that buyer is allowed to purchase is 1e-06 source token.

Protocol fee limitations

As mentioned in the Protocol Fee section, a protocol fee is charged on every accepted offer. This means that the minimum destination token amount needs to be large enough to cover a 1% protocol fee. The destination token amount is calculated based on the exchange rate set by the seller. Therefore, the minimum destination token amount depends on the token's precision and the exchange rate.

In the following tables, you may see, how different exchange rates affect the minimal source token amount that buyer can purchase for different tokens in role of destination token.

ETH or ERC20 as destination token

ETH or ERC20 tokens typically have 18 decimals. This high level of precision removes any additional restrictions on the minimum source token amount.

SOL or TON or JETTON as destination token

SOL, TON and JETTONs generally have 9 decimals number, which imposes greater restrictions on smaller exchange rates due to the reduced level of precision.

SPL or TRX as destination token

TRX and Solana SPL tokens generally have 6 decimal number, resulting in even stricter limitations on the minimum source token amount for low exchange rates due to the reduced precision.
