Solana Escrow Explained: Why Non-Custodial is the Future
In the world of online commerce, "escrow" is a familiar term. It refers to a third party holding funds while a transaction is being completed. But traditional escrow has a major flaw: you have to trust the third party. Non-custodial escrow on Solana changes the game.
The Magic of PDAs (Program Derived Addresses)
On the Solana blockchain, our escrow system uses what are called PDAs. Unlike a normal wallet, a PDA does not have a private key. It is controlled exclusively by the logic of a smart contract.
When you start a deal on Info Market:
- A unique PDA is created for that specific transaction.
- The buyer sends SOL to this PDA.
- The funds sit there, visible to everyone on the blockchain, but
frozen. - Neither the Info Market team nor any hacker can "withdraw" these funds.
Code is Law
Because there is no human intermediary, the release of funds is governed by strict rules written in the Anchor framework:
- If the buyer confirms, the funds go to the seller.
- If a dispute is opened and ruled upon, the arbitrator's signature triggers the release.
- If 48 hours pass with no action, the funds auto-release to protect the seller from "unresponsive" buyers.
Why Solana?
Speed and cost are the primary reasons. On other chains, an escrow transaction might cost $10-$50 in fees. On Solana, it costs less than $0.01. This makes it viable to protect even small $5 or $10 digital goods trades with high-grade security.
By removing the "human element" from holding money, Info Market provides a level of security that traditional marketplaces simply cannot match.
