ETH Orders and Smart Contracts
Some blockchains, like the Ethereum blockchain, support a specific type of transaction called a smart contract.
Smart contracts were designed by Nick Szabo as a way for two parties to transact with one another without involving the services of a validated third party - instead, the contracts are self-executed on the Blockchain network under stipulation. Put simply, it's code that provides a way to digitally record and execute an agreement (transaction) between two parties
Unfortunately, since smart contracts are technically different from 'regular' currency transactions, some wallet providers do not support them. In these cases, one of two things will happen:
- Despite being confirmed on the blockchain, the coins may never arrive in your wallet, OR
- Your wallet provider needs to manually approve the transaction, causing unpredictable delays
Here are some of the known providers with this issue:
