About

Eth Hodler a simple contract that allows you to lock up Ether.
This contract has no owner and cannot be modified by anyone.

There are also some other features to make it more fun:

Each deposit to the Eth Hodler locks your ether and issues you with HODL tokens. These tokens
are then used to make a withdrawal and burned once the withdrawal is processed.

A normal withdrawal would take ~30 days to process, costing only the gas fee.
Should the holder want to withdraw their deposit early, they can, but
they must pay a %1 fee. The fees will be added to a fee-pot. Holders can claim
a chunk from the fee-pot, see the rules to find out how.

How To Use

This page is a DApp (Decentralized application) meaning that you'll need an Ethereum browser to use this.

The easiest way to get started is to download the MetaMask extension for Chrome.

MetaMask is currently probably the best way to use at this time as it offers the lest friction.

Mist Wallet - instructions for the professionals

It's much easier to use an Ethereum Browser / MetaMask, but you can also use the Mist wallet by itself if you have the patience. (Or another non-browser wallet that supports contracts / tokens)
