Sorry, you cannot participate in our ICO as you did not pass our KYC process and your Ethereum address was not whitelisted in our database. ![](https://cdn-images-1.medium.com/max/800/0*jjpexPL0bn_gCDDW) #### **Step 4：Check and Verify Smart Contract Address** Please follow the instructions on our only official website [https://www.oneledger.io](https://www.oneledger.io/) to check and verify the contribution smart contract address. Please remember to verify the addresses with our Telegram announcement channel, video and ENS name as instructed on the website. #### **Step 5: Send ETH** After you check and verify the ICO smart contract address on our website [https://www.oneledger.io,](https://www.oneledger.io%2C/) you can send ETH to the ICO contract **after** it starts. Please note that your allocation on the first day is **GUARANTEED **if your Ethereum address is whitelisted. You can only contribute once every 24 hours. We recommend you record your transaction time so you can calculate when your next contribution time will begin, which is 24 hours after your last transaction. **Important**: Our smart contract will only accept transactions after 24 hours have elapsed from the previous transaction. If you send a transaction early — before the 24-hour period has elapsed — our smart contract will reject your payment and you will not be refunded the transaction fee. For instance, if you are in Tier 3. Then on **day 1**, you can contribute up to 0.7954 ETH. Go to [https://www.myetherwallet.com/](https://www.myetherwallet.com/) (MEW), and enter your **whitelisted** Ethereum account page. You can type in oneledgertech.eth in the To Address field, and verify again the showed contract address matches the one in the video on our website [https://www.oneledger.io.](https://www.oneledger.io./) **The minimum gas required is 150,000 and the recommended gas amount is 250,000.** ![](https://cdn-images-1.medium.com/max/800/1*ValMkeK6O7tPw3_Wt7eilQ.png)   On **day 2**, you can repeat the same process to contribute up to 0.7954 * 2 = 1.5908 ETH after 24 hours of your last transaction. If you are among other Tiers, then basically follow the same procedure with different allocations. On **day 3 **(after 24 hours of last transaction), you won’t have a contribution limit. You can purchase additional OLT tokens only if there is spare unsold allocation. #### How to receive OLT OLT will be minted directly by the ICO smart contract into your Ethereum address right after your transaction goes through. You will be able to see related ERC20 token transaction information on [https://etherscan.io/](https://etherscan.io/) with your transaction ID. After the ICO, we will announce the OLT token address so that you can add a custom token with it in MEW. #### When will OLT be unlocked OLT will be locked until being listed on our official exchange partner. **Thank you for being part of the OneLedger community.** **We would not have been here without you.** Tags: [GENERAL](https://blog.oneledger.io/tag/general), [ALL](https://blog.oneledger.io/tag/all) ### You may also like - ## [AMA RECAP - Internal Update 07/07/2022](https://blog.oneledger.io/internal-ama-recap-07/07/2022) [Read more ](https://blog.oneledger.io/internal-ama-recap-07/07/2022) - ## [AMA RECAP - WORLD TOKEN/ ONE PUNKS NFT  12/05/2022](https://blog.oneledger.io/ama-recap-world-token/-one-punks-nft-12/05/2022) [Read more ](https://blog.oneledger.io/ama-recap-world-token/-one-punks-nft-12/05/2022) - ## [OneLedger Technology Inc partners with Effective Marketing Solutions to deliver a unique decentralised exchange](https://blog.oneledger.io/oneledger-technology-inc-partners-with-effective-marketing-solutions-to-deliver-a-unique-decentralised-exchange) [Read more ](https://blog.oneledger.io/oneledger-technology-inc-partners-with-effective-marketing-solutions-to-deliver-a-unique-decentralised-exchange)
