How to participate Ethereum token crowdsale and which wallets are compatible?

Instructions for participating Ethereum token crowdsales

To participate Ethereum token sale you need a wallet service or an application where you and you only holds the private keys. Private keys are needed to correctly interact with smart contract functions, like transferring tokens.


Participating the token sale

  1. Buy ether in a cryptocurrency exchange
  2. Transfer ether to a compatible wallte (see below)
  3. Send a deposit to token sale address with correct data and gas limit values

Sending a token sale transaction

token sale deposit transactions need to have non-default gas limit (a.k.a. transaction maximum gas). This is because token sale transactions are more complex than simple Ethereum transfer transactions. The default gas limits is too low to correctly perform a token sale deposit.

To participate an Ethereum token sale you need to fill your transaction with following details

  • Address - this is given you on the crowdsalse deposit page.

  • Data - this is your personal reference number and it changes for every transaction. Do not share this with others. If you leave data field out your transaction is rejected.

  • Gas limit: 250000 - gas tells that this is a smart contract transaction and is more expensive than normal Ether transfer.

Note: If you are using please double check your the gas limit field value after filling the data field. MyEtherWallet may reset the gas value to an invalid number after inputting the data field.
