Response to the RFP #003 (Complex Vouchers) > [@\[RFP #003\] \[BEGINNER\] \[SOLIDITY\] Complex Vouchers](https://governance.cartesi.io/t/rfp-003-beginner-solidity-complex-vouchers/90): > > Introduction: Cartesi DApps interact with external parties, including smart contracts and other DApps, through the use of vouchers. Vouchers are designed to be highly generic, enabling a wide range of potential interactions and use cases. This level of flexibility opens up the possibility of expanding the behavior of vouchers to support more complex interactions by targeting smart contracts that extend their functionalities. This Request for Proposal (RFP) aims to encourage the development of a… - Deliverables: Solidity library with each specified voucher caracteristcs quoted in the RFP as listed below: - Detailed test report for the library - A user guide that provides step-by-step instructions on how to use the Solidity library. - Duration: 1 month - Funds request (USD) : 2000 - The Team: -Felipe Bizzo - Blockchain engineer Linkedin: [https://www.linkedin.com/in/felipe-bizzo-81b709131/?locale=en\_US](https://www.linkedin.com/in/felipe-bizzo-81b709131/?locale=en_US) ## ERC-20 Payee address: 0x6a1f1531255df3a703dd1610d22c8524d133367b ---

Thanks for the submission! Your proposal does not include progressive deliverables or milestones. Should we assume all deliverables will be presented at once, with a single payment upon successful completion? Besides this confirmation, I have no objections to the proposal and suggest that it be sent to voting immediately. ---

Yes, that is correct. Since it is a small project I had not seen the need to split it in multiple deliverables. However, I am open to changing that if it is best for the project. ---

Thanks for your reply. We will move this forward to a vote on Snapshot, with the assumption of a single milestone payout. I will post the Snapshot link here when it is live. ---

**Grants Council Commentary:** This RFP has been completed and the Grants Council has awarded @Sidocha with 2000 USDC for their outstanding work on the Complex Vouchers RFP. We see a Solidity library that extends the expressiveness of Complex vouchers as something needed for Cartesi dapps. The code can be reviewed here, [GitHub - cartesi/rollups-contracts at feature/complex-vouchers](https://github.com/cartesi/rollups-contracts/tree/feature/complex-vouchers) ---
