The payment locked up in the contract will be released directly to the seller’s wallet address entered in the contract terms. In other words, you receive payment to your Metamask address and not Zenland account. This can be verified via Etherscan, or another applicable blockchain explorer.
Your Zenland (in-app) wallet is only for the service fees for creating a contract and does not support any operations with the contract.
