Does anybody know a good way of creating a tranche based bonus as opposed to a time based bonus for a crowdsale? I’m looking to create a crowdsale that starts at a certain price per token but the price increases by .05% depending on how many tokens have been sold so far.

Hi @Roodiger In your test, the line you were missing is, this goes after you have created your crowdsale: await this.token.transfer(this.crowdsale.address, this.totalSupply); Please ask all the questions that you need. Everyone was new once (see top three recommendations for a new developer …

Hi @Roodiger welcome to the community :wave: You can take inspiration from the IncreasingPriceCrowdsale.sol You could override the _getTokenAmount function of Crowdsale to use the current rate and then have a function getCurrentRate which has your rate calculation based on how many tokens have bee…

Thank you so much for the reply! I already use Truffle for testing, but thanks for sending the guide over, that will be helpful. I’m new to programming tokens. I come from Java development, and have taken a keen interest in Solidity, Ethereum, and tokens. I’m just having some troubles with getting …

Hi @Roodiger Welcome to developing token smart contracts. Are you developing for a specific project or are you learning? Feel free to ask all the questions that you need. The OpenZeppelin documentation is great for reading up on some of the different options for tokens and crowdsales I think th…

Hey @abcoathup Thank you! A bit of both. It’s for a project, but it’s more so of a learning project for me. Yeah more like the first one. I just want to make it so that every 50,000 tokens sold changes the rate by .05%. Most of the places I looked showed bonuses by time instead of by token supp…

A participant in your crowdsale either sends Ether to your contract or calls the buyTokens function sending Ether. buyTokens calls the function _getTokenAmount in MyCrowdsale that overrides the function in Crowdsale. _getTokenAmount then calls the getCurrentRate function which has your algorithm f…

Is there a simple way to make the algorithm so that the rate multiplication happens every time 50,000 more tokens gets sold? Instead of having to manually make the tiers? Like, is there a way to see how many tokens have been sold so far and only multiply the rate if it’s been 50,000 more than last t…

Hi @Roodiger it depends on your chosen token emission . There is lots of flexibility. :smile: For example, if you used default emission, then you could use the balance of tokens controlled by the contract subtracted from the total supply to calculate how many were sold, otherwise you might need a p…

So what I have so far is kind of a wreck. I can’t seem to get it right quite yet. Where exactly do I send the crowdsale the tokens? And how do I go about that? I know that you use the transfer function, but just can’t seem to get it right. This is what I have so far. I have my crowdsale and my crow…

Hi @Roodiger Some housekeeping: Assuming my reply answered your question, can you mark it as the solution please. I moved your other questions into new topics. It is best to have a new topic per separate question as that is easier for the community to answer and hence get you an answer quicker …
