Ethereum smart contract and library for efficient ERC20 and Ether balance checks.

Ethereum smart contract and library for efficient ERC20 and Ether balance checks.

Truffle Boilerplate with solium, linguist, zeppelin, migrations, tests &tc

An extension to the ERC-20 standard token, which allows tokens to be put on hold. This guarantees a future transfer and makes the held tokens unavailable for transfer in the mean time. Holds are similar to escrows in that are firm and lead to final settlement.

The clearing process turns the promise of a transfer into the actual movement of money from one account to another.
