wc_new_connection
The wc_new_connection method returns a connection string which can be scanned as a QR code.
Once the connection has been established, you can activate EVM and Tendermint coins/tokens with WalletConnect via the priv_key_policy parameter in enable_eth_with_tokens and enable_tendermint_with_assets.
EIP155 chain IDs are listed at https://chainid.network/. Cosmos chain IDs are listed at https://cosmos.directory/. For more detailed technical information, check out the Walletconnect documentation.
| Structure | Type | Description |
|---|---|---|
| required_namespaces | object | Contains two WcConnNs objects under the keys eip155 and cosmos, which contain details of approved chains, methods and events while connected. |
| Structure | Type | Description |
|---|---|---|
| url | string | A WalletConnect URI address (EIP-1328) used to send a connection request to the bridge server. |
Generally, this WalletConnect URI will be converted into a scanable QR code in graphic user interfaces, so mobile dapps can easily request a connection.
When connecting with Metamask, only the network currently active in the mobile app should be included under the required_namespaces.eip155.chains parameter. The Metamask app will handle any subsequent coin network changes.
