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



IMPORTANT: DO NOT SEND EXPANSE TRANSACTIONS DIRECTLY FROM CRYPTOCURRENCY EXCHANGES. YOU NEED AN EXPANSE-COMPATIBLE TOKEN WALLET TO PROCEED.

Steps to Participate in the Tokenlab Sale

Buy EXP in a cryptocurrency exchange. Transfer the EXP you purchase to an EXP-compatible wallet (see below). Send an EXP deposit from your EXP wallet to the token sale address with correct Data and Gas Limit values. (Extra EXP is needed to cover the extra gas required for this complex transaction. The Expanse Mist wallet automatically calculates the correct amount.)

Compatible Wallets

The following wallets are known to be compatible with Expanse tokens (ERC-20 standard):

Expanse Mist Wallet (Desktop)

Parity (Desktop)

MyEtherWallet - Make sure to choose the Expanse Network (Online)



Incompatible Wallets

Important Note: Before you begin, first move your EXP to a compatible wallet as outlined above. Do not use the following wallets to participate in any Tokenlab token sale.

Poloniex

Bittrex

Other wallets - If you know of any other wallets that are known to behave correctly with ERC-20 tokens, please contact us at contact@expanse.tech.

Sending a Token Sale Transaction (Buying LAB)

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

To participate in a LAB token sale, you need to access the EXP wallet where you have stored your EXP for the sales. Then make sure the following details are provided for each LAB purchase transaction:

Address - This is provided for you on the Tokenlab crowd sale deposit page.

- This is provided for you on the Tokenlab crowd sale deposit page. Gas Limit: Enter 250000 if using MyEtherWallet. (If using the Expanse Mist wallet, the amount of gas needed is calculated for you.) The Gas Limit entry is necessary, given that this is a smart contract transaction and is more expensive than a normal EXP transfer.

Important Note: If you are using MyEtherWallet, please double-check the Gas Limit value after filling information into the Data field. It must reflect 250000. MyEtherWallet may reset the Gas Value to an invalid number after entering information into the Data field.

Troubleshooting

Incorrect Gas Limit - If you set the gas limit value too low, your transaction is rejected and automatically refunded. The transaction might not appear in the blockchain explorer.
