Guide for asset issuers

How long will it take to review and approve my asset listing application?

The time it takes to review a new listing can vary depending on many different factors, so we cannot offer any specific guidance on the time needed to review your listing. Typically, we can review applications for tokens issued on a blockchain that Coinbase already supports (for example, ERC-20 tokens issued on Ethereum) more quickly than we can review applications for tokens issued on blockchains that Coinbase does not yet support. 

More resources about our asset listing application review process are available here:

What can I do to speed up my asset listing application?

The best way to ensure that your asset listing application is processed as quickly as possible is to fill out the application accurately and completely. If we reach out to you with a question about your application, please respond promptly. 

Do I need to submit a third party legal opinion or security audit with my asset listing application?

You are not required to submit a third party legal opinion or security audit with your asset listing application, but if you have these materials, please feel free to include them with your application and we will consider them.

If Coinbase approves my asset listing application, how long after approval will it take for my asset to be listed on Coinbase?

If your asset is the utility token of a blockchain that Coinbase does not already support, then once we approve your application, you will need to create your Rosetta Implementation, which typically takes about six weeks. 

We’ll then verify and validate your Rosetta Implementation, after which we can integrate your listing with our internal wallet services. The time needed to do this can vary depending on the blockchain on which your token exists. 

We will automatically notify you when there are updates to share. 

If your asset is a token that trades on a blockchain that Coinbase already supports (for example, an ERC-20 token issued on Ethereum), then we will automatically notify you when there are updates to share. 

Is Rosetta Implementation necessary to list my asset on Coinbase?

Rosetta implementation is necessary to list your asset if it is on a blockchain that is not currently supported on Coinbase. 

If Coinbase rejects my asset listing application, how long do I need to wait to re-apply?

If we reject your listing application, you should wait at least six months to re-apply.
