Over-the-counter trades take place in Telegram groups, forums and direct messages where nobody enforces the trade. The usual problem is well known: one side sends first and the other party disappears. Escrow fixes this by taking custody of the crypto side until payment is confirmed. This is practical with stablecoins, Bitcoin Escrow - https://cryptoescrowdesk.com and major altcoins, and the cost is easily justified by the amount at risk.

Scam escrow websites are widely used in crypto fraud - http://www.techandtrends.com/?s=crypto%20fraud . The scammer proposes a particular escrow provider, which is theirs, and the payment is simply stolen. Red flags include no operating history, fees that are unclear, no resolution mechanism, anonymous ownership and especially insistence on a single provider. Any genuine service has nothing to hide and will be agreed by both parties.

Telegram and Discord groups are full of self-appointed middlemen. The concept mirrors escrow: someone neutral takes custody. What separates the two is what happens when things go wrong. An anonymous MM keeps no auditable record, no formal resolution path and no verifiable identity. A proper escrow operation records every deposit, publishes its fees and crucially provides a resolution mechanism defined before any money moves.

Escrow for cryptocurrency use one of three models. A custodial service - https://app.photobucket.com/search?query=custodial%20service holds the funds and settles when staff signs off, which suits anything that might need a person to decide. Multisig needs multiple signatures to move funds, limiting what any one party can do alone. Contract-based escrow executes automatically on a defined trigger, which is efficient for simple, verifiable conditions though handles disputes poorly.

Crypto transactions cannot be reversed, so this creates a trust problem whenever two strangers deal. An escrow arrangement closes that gap with a neutral third party between the two parties. The buyer deposits, the seller performs, confirmation follows and at that point the funds are released. Neither party has to move first. A typical fee tends to be a fraction of the deal value, which is trivial compared with losing the entire payment.
