Web3 authentication implemented in Scala 3 on top of ZIO

• User will be identified from his/her wallet address

Current version only supports evm wallets (ETH, BSC, etc.)

• User needs to request a challenge before login
• User has to sign the challenge with its private key
• Signature is validated and a token is created with all relevant information about the user

Token format supported: JWT

• Token can be validated and then extract the information about the user (claims)

Claims example { "sub": "urn:wallet:$wallet-address", "iac": 123456 }
