 Tofn provides the following:
 
 * An implementation of ECDSA SECP256k1 signing scheme.
 * An implementation of ED25519 signing scheme.
 
+tofn is primarily used as part of [tofnd](https://github.com/axelarnetwork/tofnd) for the [Axelar network](https://www.axelar.network). For an older version of the library that included a threshold ECDSA implementation, see the section below on Threshold cryptography.

The GG20 protocol implementation should not be considered ready for production since it doesn't protect against [recently discovered attacks](https://www.verichains.io/tsshock/) on the protocol implementation. This was removed from `tofn` as it is not being used in the Axelar protocol.
