This library support only ed25119 base64 format ?

Hi @peacekeeper the signing format in the proof is now base64 format for ed25119
but i need base58btc format whether is possible to do that ?

Signing isn't done by this library, but by ld-signatures-java, e.g. here:
https://github.com/WebOfTrustInfo/ld-signatures-java/blob/main/src/main/java/info/weboftrust/ldsignatures/signer/Ed25519Signature2018LdSigner.java

Ed25519Signature2018 uses Base64, not Base58btc.

Can you clarify what you mean?
