  • #2292: Switch to maker-taker fee model. Major Trade model rework

    This patch replaces side-related (buy or sell) with maker-taker fee model. Its basic structure gives a fee discount to market makers providing liquidity (the makers); and charges higher fee to customers who take liquidity out of the market (the takers). Fee could be configured per market. Next changes were produced by switching to maker-taker fee model:

    • Replace ask_fee and bid_fee with maker_fee and taker_fee in Market model;

    • Specs for maker/taker_fee;

    Trade model rework consist of next changes:

    • Update Trade model structure:
    • ask_id -> maker_order_id;
    • bid_id -> taker_order_id;
    • ask_member_id -> maker_id;
    • bid_member_id -> taker_id;
    • volume -> amount;

  • #2347 Beneficiaries model with ability to manage via user API (mod)

    Add Beneficiary model which can store both fiat crypto beneficiary data. Custom beneficiary fields like country, account_number, bank_swift_code are stored in JSON format. Also beneficiary contains name, description & currency_id in string format.

    On beneficiary creation pin generated and saved in DB user needs to activate beneficiary with pin sent by email. Create & update actions are published to RabbitMQ by Event API.

    There are 3 states of beneficiary:

    • pending - requires activation with pin;
    • active - activated by user and can be used for withdrawal;
    • achieved - equal to removed except fact that admin can read it.

    Beneficiary account API consists of 5 endpoints:

    • GET /beneficiaries - get paginated list of beneficiaries for user;
    • GET /beneficiaries/:id - get single beneficiary by id;
    • POST /beneficiaries - create beneficiary for user;
    • PATH /beneficiaries/:id/activate - activate beneficiary with pin;
    • DELETE /beneficiaries/:id - delete beneficiary (actually change state to archived).

  • #2355: Integrate ability to withdraw both fiat & crypto with Beneficiary model (ysv)

    Since we can store Beneficiaries in peatio starting from #2347 now we can implement user withdraw API for both fiat & crypto currencies. Itmeans that in this patch we have replaced POST accounts/withdraw rid param with beneficiary_id. This change gives ability to use active beneficiaries for both fiat & crypto withdrawals.

    Beneficiary is now exposed in Admin API as field of Withdraw so admin can validate it directly.

    beneficiary_id foreign key was added to Withdraw model so now it has optional belongs_to association with Beneficiary.

    Also this patch improves Withdraw sum & amount precision logic. Instead of rounding attributes on creation now attributes precision is validated on Withdraw creation.

    This patch also adds additional validation for Beneficiary data attribute
