ERC20 example

Repository contains implementation of the example smart contract and deployed sig/mtp validator onchain zero-knowledge proof verification.

We aim to provide deployment of:

• Atomic query MTP validator https://github.com/iden3/contracts/blob/master/contracts/validators/CredentialAtomicQueryMTPValidator.sol
• Atomic query Signature validator https://github.com/iden3/contracts/blob/master/contracts/validators/CredentialAtomicQuerySigValidator.sol
• Example contract that inherits ZKP Verifier contract https://github.com/iden3/contracts/blob/master/contracts/verifiers/ZKPVerifier.sol

Also, it contains the example of ERC20 based smart contract with enabled zkp verifications for token transfers.
