The Project ID is consumed through URL parameters.
URL parameters used:
projectId
: Your Project ID can be obtained from cloud.reown.comExample URL:
https://relay.walletconnect.com/?projectId=c4f79cc821944d9680842e34466bfbd
This can be instantiated from the client with the projectId
in the SignClient
constructor.
To help prevent malicious use of your project ID you are strongly encouraged to set an allowlist of origins or application/bundle ids for mobile applications where the project ID is used. Requests from other origins will be denied.
[scheme://]<hostname[:port]
.Using localhost
(or 127.0.0.1
) is always permitted, and if empty all origins are allowed. Updates take 15 minutes to apply.
If scheme or port is specified, it must match exactly. Hostname must also match exactly, but wildcards can be used for individual labels within the hostname.
Example of possible origins in the allowlist:
example.com
- allows https://example.com
or http://example.com
but not https://www.example.com
https://example.com
- allows https://example.com
but not http://example.com
https://www.example.com
- allows https://www.example.com
but not https://example.com
https://example.com:8080
- allows https://example.com:8080
but not https://example.com
https://*.example.com
- allows https://www.example.com
but not https://example.com
https://*.*.example.com
- allows https://www.subdomain.example.com
but not https://www.example.com
or https://example.com
