After this step your IDO sale page answers on your own domain: https://ido.your-domain.com/<chainId>/<contract>/<template>. The domain does not exist on-chain — it is a DNS record pointing at our entry point, so binding alone opens nothing until that record resolves.

Tip · Order of operations

Add the DNS record first, then save the domain in the console. You can bind first if you like, but the domain only starts working once the record has resolved.

Open the DNS records page for your domainSign in where you bought the domain (GoDaddy, Aliyun, Tencent Cloud, Cloudflare, Namecheap, and others), open your domain list, pick the domain you want, then open DNS / DNS records / Manage DNS. Every registrar names it differently — DNS, DNS records, domain resolution, Manage DNS.
Add a CNAME recordType: CNAME. Host / Name: ido. Value: dns.gtokentool.com. Leave TTL at the default. Enter only ido as the host — some registrars append the domain for you, so typing ido.your-domain.com ends up as ido.your-domain.com.your-domain.com.
Wait for the record to resolveUsually under 10 minutes. A freshly registered domain, or one whose nameservers just changed, can take about an hour. The direct check: open ido.your-domain.com — if the IDO page loads, it is live.
Save the domain in the consoleOpen the My IDOs console → Project site · domain binding → enter ido.your-domain.com → Save domain. Once saved, the link on that panel is your project site and can go straight to your community.

DNS records page at a domain registrar, with the Add new record button outlined — Figure 1: on your registrar’s DNS records page, click Add new record (some providers label it “Add record”).

Add record form with type cName, name ido and value dns.gtokentool.com — Figure 2: set type to CNAME, host name to ido, value to dns.gtokentool.com, then save.

Console domain setting: after the domain is entered it confirms verification and shows the CNAME record to add — Figure 3: back in the console, enter ido.your-domain.com (the old screen called it “Domain settings”; the current console has it under Project site · domain binding), then add the record from the table above at your registrar. The console does not check resolution for you — open the domain yourself once it has had time to propagate.

Careful · A root domain cannot be CNAMEd directly

Per DNS rules a root domain like example.com cannot be a CNAME target, so the subdomain ido.example.com is the easy path. If you must use the root, you need ALIAS / ANAME records from your DNS provider, or move the nameservers to one that supports CNAME flattening.

Field	What to enter
Type	CNAME
Host / Name	ido
Value	dns.gtokentool.com
TTL	Default (10 minutes or 1/2 hour both work)

Still not opening after an hour: confirm the CNAME saved and the host name is right, then confirm the domain’s nameservers still point at your own DNS provider.
Keep one CNAME per host name — duplicate records fight each other and resolution gets unpredictable.
The console rejects the domain: enter ido.your-domain.com only, with no https:// and no path after it.
Still stuck: send us the domain and a screenshot and we will dig in.
