DEX v2 guide

This section contains SDK reference for DEX

The remaining sections of the documentation will demonstrate specific examples of the DEX usage:

Referral Fees

DEX v2 stores each swap's referral portion in a dedicated Vault contract (one per referrer × token pair). The fee percentage can be set between 0.01 % and 1 % and must be withdrawn later by the referrer.

Inspect vault balances and history using the Stats & Vaults REST API:

  • GET /v1/wallets/{addr_str}/fee_vaults – lists all known vaults per referrer

  • GET /v1/stats/fee_accruals – shows all operations leading to fee accrual for the referrer, filterable by period

  • GET /v1/stats/fee_withdrawals – lists withdrawals from the referrer's vaults by period

  • GET /v1/stats/fees – returns aggregated referral fee information, for example total accrued USD value

See the Omniston referral fees guide (note: although the guide is Omniston-oriented, the referenced paragraph explains DEX V2 referral fees in detail). Full API documentation is available in the Swagger UI.
