Description
We have brought two protocols already widely established on EVM to Polkadot PassetHub Testnet:

• Ethereum Attestation Service (EAS) is an open-source infrastructure public good for making attestations onchain or offchain. It's already used from popular platform like Coinbase as KYC for the withdraw address, Uniswap for KYC pools and is automatically implemented in every new Superchain from Optimism
• Sablier is one of the most well-established protocols in the EVM ecosystem for streaming payments. We have implemented their Flow smart contract, which does not require an upfront deposit and has no fixed start or end dates. This makes Flow ideal for use cases such as payroll and grants, as it is all about flexibility.
