Synthetix sUSD bridge is live

The most popular stablecoin on the Optimism Foundation, sUSD, has improved and the sUSD bridge has been enabled. Users may now transfer sUSD between Ethereum Mainnet and Optimism, and users are allowed to transfer in both directions.

All sUSD transfers must be carried out through direct contract interactions. To make transferring sUSD between chains simple, a guide has been prepared.

Step 1: Approve sUSD to be bridged by the Synthetix Bridge contract on Optimism
Step 2: Write and call “initiateSynthTransfer” on the Synthetix Bridge Contract
Step 3: Write the transaction and wait for confirmation

Scroll is releasing the pre-alpha version for external testers

After working closely with the PrivacyScaling team at the Ethereum Foundation for more than a year to develop zkEVM-based zkRollup, Scroll is now releasing the pre-alpha version of it accessible for external testers.

The first release will run on a privately managed PoA fork of the Ethereum testnet L1 run by Scroll. Early adopters and developers will have the first opportunity to engage with Scroll's infrastructure and test out dapp workflows on the pre-alpha testnet.

Users and developers alike benefit from ZK proofs' futuristic features while also enjoying Ethereum's decentralization, security, and familiarity.

The performance of Polygon's ZK teams has considerably improved, and proof generation times have been reduced. By doing this, Polygon zkEVM is now ready for utilization, and users will see significantly lower prices and faster performance. Users may deploy any Ethereum smart contract and develop on Polygon zkEVM in the same way they do on Ethereum. Any toolset that is compatible with Ethereum is also compatible with Polygon zkEVM.
