But for now, I cannot see these constants in the SDK, and when I tried using string directly, I received an error: [![sapphire_invalid-network](https://canada1.discourse-cdn.com/flex011/uploads/metamaskbuilderhub/original/2X/e/ee7eddb8c081cc548c9c1480c1956b4fb40b57d2.jpeg) sapphire\_invalid-network1290×2796 110 KB ](https://web3auth.io/community/uploads/default/original/2X/5/5a4c4123cfcb6ce486534a47142ffcedb7a04638.jpeg "sapphire\_invalid-network") I check the community and see [this comment](https://community.web3auth.io/t/sapphire-mainnet-type-is-missing-from-torus-network/4350/4) said it will available by June and early July. I also got an email from Web3Auth that old networks will be migrated to Sapphire in 15-16 July. So I just want to ask if will react native SDK support sapphire networks now (or in the future) so I can use it in my project? ---

We’ve re-enabled testnet support on developer dashboard. Please use that for your development. Sapphire Devnet support for plug n play will be live before the end of this month ---

Hi @vjgee, I tried it but still received an error: “invalid constructor params, network or sdk url”. I even updated “@web3auth/react-native-sdk” to v4.0.0 but that also did not help. I joined last Wednesday Zoom meeting and heard that react native v4 demo and docs will released soon, But I’m still not saw it yet. ---

Plug and plug sdks will support sapphire network once migration is done from existing networks to sapphire. We understand that this might be critical for your product but we are trying our best to complete migration without any damage or downtime hence things are bit slower than wht we expected. We will keep you posted on our community channels once migration is completed.Thanks for your patience and support.
