People ask which one is safer. The honest answer is that they fail differently. A smart-contract escrow is safer against the escrow itself: nobody can take the coins because nobody holds them, code does. A custodial escrow is safer against the deal: when the goods did not arrive or the bank transfer never cleared, there is someone who can read the evidence and decide. The question is which failure you are protecting against.
Where a smart contract is better
- No custodian to trust, no platform that can freeze or lose your funds. If both legs of the deal are on the same chain and the condition is verifiable on-chain, this is the cleaner design.
- Transparent: anyone can read the contract and see the funds locked.
Where it stops
- It cannot see a bank transfer, a PIX, cash, or a shipping document. Every crypto-for-fiat trade, every goods or services deal, needs someone or something off-chain to say "the condition was met".
- Disputes still need a decider. Most "trustless" escrows end up with an arbiter, an oracle or a multisig of people, which is a custodian with extra steps.
- A bug is final. There is no one to call.
Where custodial is better, and what it costs you
- It can hold the crypto while the other side pays in any method of your country, and an arbiter can read receipts, chats and documents and decide with the reason in writing. That is the whole use case of P2P and of goods and services.
- It costs you trust in the custodian. iEscrow is custodial: the platform controls the escrow addresses until release. We say it plainly because the alternative is claiming to be something we are not.
- What makes that trust checkable instead of blind: the mechanism is written down (30-minute windows, automatic escalation, no cancellation after acceptance), the dispute decision comes with the reason, and the funds are not in anyone’s personal wallet.
Practical rule: crypto for crypto on one chain with an on-chain condition, a smart contract is enough. Crypto for fiat, goods, services, or anything that needs a human to say "delivered", you need an arbiter, and then the question is who holds the funds and how clearly they say so.
