 ## Requesting signatures
-At its core the Signer Module simply provides a signature on a 32-byte data digest. The signatures are currently provided with either the validator keys (BLS) or a proxy key (also BLS) for a given validator key, both on the [builder domain](https://github.com/Commit-Boost/commit-boost-client/blob/main/crates/common/src/signature.rs#L88-L96). Eventually we plan to support [alternative](https://github.com/Commit-Boost/commit-boost-client/issues/20) signing schemes, too.

 ### With a proxy key

+You'll have to first request a proxy key be generated for a given consensus key.
+We support two signature schemes for proxies: BLS or ECDSA.
+
+To request a proxy:
 ```rust
-let proxy_delegation = self.config.signer_client.generate_proxy_key(pubkey).await?;
+// BLS proxy
+let proxy_delegation = self.config.signer_client.generate_proxy_key_bls(pubkey).await?;
+let proxy_pubkey = proxy_delegation.message.proxy;

+// or ECDSA proxy
+let proxy_delegation = self.config.signer_client.generate_proxy_key_ecdsa(pubkey).await?;
 let proxy_pubkey = proxy_delegation.message.proxy;
 ```
 
 Where `pubkey` is the validator (consensus) public key for which a proxy is to be generated.
 
-Then, the only difference from the direct approach is explicitly saying that the signature request uses a proxy key:
