Developers can now build applications on Arbitrum Nitro chains using WASM-compatible languages, including Rust, C, and C++. The launch includes the release of the code, a public testnet, and an SDK. According to the project, Stylus significantly lowers gas costs. Developers can build resource-intensive blockchain use cases, including alternative signature schemes, larger generative art libraries, and C++-based gaming. Offchain Labs will host a Stylus Hackathon at ETHGlobal in NY on September 22nd and will offer $20,000 in bounties. **Prisma Finance Goes Live** ---------------------------- Prisma Finance, an LST-backed stablecoin protocol, is now [deployed](https://mirror.xyz/prismafinance.eth/6UbQ6QAaodBuXvaFNrzGr1jPAzDR5fMLcJb6AxzB_Ac) on Ethereum Mainnet. Starting on September 1st at 9 am UTC, users will be able to mint the mkUSD stablecoin using wstETH, cbETH, rETH, or sfrxETH as collateral. Debt caps will also be enforced for each collateral during the initial launch. Prisma will also release its PRISMA token, which can be locked for vePRISMA, enabling governance voting power. LST issuers can channel incentives towards their own assets using vePRISMA. In a bid to bootstrap TVL, Prisma is introducing a 0% initial interest rate. Prisma is built on the codebase of Liquity Protocol. **Optimism Highlights 🔴✨** --------------------------- **Gitcoin Passport Introduces Onchain Stamps** Identity verification platform Gitcoin Passport [introduced](https://www.gitcoin.co/blog/gitcoin-passport-onchain-stamps) onchain stamps on OP Mainnet. An onchain stamp is a verifiable credential stored onchain. The solution uses  Ethereum Attestation Service (EAS) for its onchain data structure. EAS is an open-source tool for onchain and offchain attestations that is available for OP Stack chains. Credentials can be assigned by various identity providers. The system aggregates stamps and assigns weights based on their cost of forgery. Stamps were previously stored offchain and required developers to query the Gitcoin Passport API to read the Unique Humanity Scores. Users can now migrate their passport onchain to OP Mainnet by visiting passport.gitcoin.co. **PoolTogether V5 Beta Release** Prize savings protocol PoolTogether [released](https://pooltogether.mirror.xyz/IeSRsl6cRCF64LqBruoHINJb1EipiBcRm-JU2U9-WuI) the fifth iteration of its protocol to private beta. The new iteration introduces immutability, permissionless vaults, and automatic yield-to-prize conversion. The private beta features boosted USDC and wETH vaults on OP Mainnet that generate a yield from Aave V3. Users with a pooly, pfer, GitPOAP, or PoolyCon POAP NFT can access the beta release. The V5 release is expected to launch for all users on October 2nd. PoolTogether also introduced Cabana.fi, a series of open-source and user-friendly interfaces for interacting with the new protocol. **Other OP News** * [![User Avatar](https://storage.googleapis.com/papyrus_images/c5bbedc41a2372425a6c88ca97c84744756fe903979c18c6f10481df82f35775.jpg)](https://twitter.com/CurveFinance) [Curve Finance](https://twitter.com/CurveFinance) [@CurveFinance](https://twitter.com/CurveFinance) [![Twitter Logo](https://paragraph.com/editor/twitter/logo.png)](https://twitter.com/CurveFinance/status/1696988969647448170) We are on @BuildOnBase ![](https://storage.googleapis.com/papyrus_images/20a3e706d233e89997c496645563e96c1aba9f69cd2d65a5cc3b20507ef904f5.jpg) [![Like Icon](https://paragraph.com/editor/twitter/heart.png) 496](https://twitter.com/CurveFinance/status/1696988969647448170)[ 3:51 PM • Aug 30, 2023 ](https://twitter.com/CurveFinance/status/1696988969647448170) * [Alchemy adds support for Base.](https://alchemy.com/blog/base-on-alchemy) * [![User Avatar](https://storage.googleapis.com/papyrus_images/f194426026b9f5208564dd915836063341797664398d97e8212fe5fa6d7cbf1c.jpg)](https://twitter.com/matchaxyz) [Matcha 🍵✨](https://twitter.com/matchaxyz) [@matchaxyz](https://twitter.com/matchaxyz) [![Twitter Logo](https://paragraph.com/editor/twitter/logo.png)](https://twitter.com/matchaxyz/status/1697301063156772971) Even more liquidity on Base now available on [matcha.xyz](https://t.co/hZioVuVKqo) ![🍵](https://abs-0.twimg.com/emoji/v2/72x72/1f375.png)![✨](https://abs-0.twimg.com/emoji/v2/72x72/2728.png)[ ![](https://storage.googleapis.com/papyrus_images/89736a280443d7729eb36b40c6132e7948e614cba427e8ccf9e9414a90a58766.jpg) matcha.xyz Matcha | DEX aggregator by 0x | Search, trade, done. ---------------------------------------------------- Matcha DEX aggregator | Search and trade over +9 million tokens across +100 exchanges on 15 chains.
