Section 01
What is Escrow?
A simple explanation for a complex trust problem
Imagine a buyer and seller who do not trust each other. The buyer does not want to pay first — what if the seller never delivers? The seller does not want to deliver first — what if the buyer never pays?
An escrow service solves this by holding the buyer's money in a secure bank account until the seller delivers. Once the buyer confirms delivery, the money is released to the seller. If there is a problem, the money stays safe until the dispute is resolved.
Prime Bank's role: The escrow funds are held in a designated Prime Bank account — not by Hold.bd. This ensures full regulatory compliance with Bangladesh Bank guidelines.
Step 1: Buyer Deposits
Money held safely in Prime Bank escrow account
Step 2: Seller Delivers
Goods or services delivered; buyer inspects
Step 3: Buyer Approves
Money released to seller via Prime Bank

Admin Approved
Hold.bd admin reviews the escrow for compliance (KYC, amounts, terms) and approves it.

Buyer Deposits
Buyer transfers the escrow amount to Prime Bank's designated escrow account via BEFTN, NPSB, RTGS, or cheque.
Bank Verifies Deposit

The escrow amount is now held securely in Prime Bank's escrow account. Neither party can access it unilaterally.
Seller Delivers
The seller delivers the goods or services as specified in the escrow terms.
Buyer Receives
The buyer receives the delivery and the inspection period begins.
Inspection Period
The buyer has a defined period to inspect the goods/services. They can accept, reject, or raise a dispute.

Prime Bank's Role
What Prime Bank does at each stage of the escrow
Fund Custodian
Holds buyer's deposit in a designated escrow account, separate from Prime Bank's own operational funds.
Funds are segregated and not commingled with the bank's own assets — fully compliant with Bangladesh Bank regulations.
Provides the regulatory standing and trust that a technology company alone cannot offer.
Deposit Verification
When a buyer deposits via BEFTN, NPSB, RTGS, or cheque, Prime Bank confirms receipt to Hold.bd operations.
Remitter name is validated against the buyer's KYC-verified identity to prevent third-party deposits.
Hold.bd admin verifies the deposit amount against the escrow record in the system.
Disbursement
When a transaction completes, Hold.bd sends disbursement instructions to Prime Bank operations.
Prime Bank transfers funds to: seller's bank account, broker commission (if applicable), and platform fee split.
Platform fee is split between KaritKarma Limited and Prime Bank PLC (revenue share — configurable from admin console).
Regulatory Compliance
